AT S T -A PORCH O THE RED BARN

The long-awaited porch on the Antique /Classic Headquarters also known as the Red Barn at Oshkosh willhave been completed by the time this issue reaches thereaders . All the design and construction work was doneby volunteers , mostly members of Antique /Classic Chapter 11 from the Milwaukee , Wisconsin area .

The project was headed up by Al Kelch of Mequon,Wisconsin who contributed many hours and dollars, andput many miles on his van driving to and from the worksite and picking up tools and materials for the job. Alshopped around and negotiated some real bargains a tlocal Oshkosh lumber and supply outlets .

Initially the covered porch was to have been only onthe north side of the Red Barn but when construction was

begun, it became obvious that there were many advantages to extending it to the east side. Not only was thearea of the porch doubled , but it now provides protectionfrom the elements for the main entry to the building.

Most assuredly, the porch is one of the choice spots onthe Convention grounds where folks can relax and visit.A big thank you and a well-deserved pat on the back isdue each volunteer who worked so hard to complete thisfine addition to the Antique /Classic Red Barn .

Aero Digest is the premier aviation journal for thosestudents of aircraft in the Golden Age of Aviation in theUnited States. Foremost in its field , this journal coveredall aspects of civil and military aviation .

Its strongest suit was in its descriptions of individualaircraft. Also covered were technological advancements,record flights, history, personality profiles, air races, andforeign activities. It was profusely illustrated with photosand three-view drawings.

The April, 1928 issue provided articles and descriptions on 18 different aircraft. Among the aircraft coveredin this issue were the Taylor Chummy , Bellanca 6-passenger monoplane , Alexander Eaglerock, Avro Avian ,and the Fokker F-I0 Super Trimotor. There was also athree-page article on the Cierva Autogiro.

The journal not only kept track of developments oflight aircraft such as the Taylor C hummy , it helped tofoster their development through the Aero Digest Trophy.This trophy was awarded to the winner of the speed andefficiency race for planes with under 80 cubic inch displacement at the 1925 New York Air Races .

Not only were the articles and notices on aircraft informative, but so were the advertisements; many of whichwere full page . Aero Digest prided itself on the amount ofaeronautic advertising . It stated that it provided a

greater variety of advertising than any other aeronautical publication. The May, 1929 issue was a good examplewith over 340 advertisers.

A large proportion of its advertising was by aircraftmanufacturers . A comparison of a 1929 issue of Aero Di-gest with one of Aviation shows that 38 % of Aero's advertising was for aircraft while Aviation had 25 %. Thus AeroDigest is a very good source for aircraft manufacturer'sinformation.

Though not noted for its cover ar t work , as most of itscovers were duo-tone Aero Digest did have some full color

nual series, which began in April, 1935, was preceded byan irregular feature - Descriptions of approved typeairplanes and engines, which first appeared in April,

1931. The descriptions were a third of a page each andprovided two photos and a three-view drawing plus specifications for each aircraft. The first appearance in 1931covered 90 aircraft from the Aeronca to the Zenith Z-6-B.The annual directory appeared as the March issue from1935 to 1956.

The size of the issues of Aero Digest reflected thegrowth of the aviation industry and the interest it genercated. In the early 20s, the issues consisted of 50 to 80pages . After Lindbergh 's flight , this jumped to 150-180pages . The size continued to grow from there with thepeak coming in September, 1929, with an issue of 366pages. The last issue of December , 1956 had only 48 pages .

Aero Digest was published by the Aeronautical DigestPublishing Corporation of New York. Its second president,Frank Tichenor, for several years provided an editorialcolumn called Air - Hot and Otherwise .

Purists in the field of prescriptive grammar wincepainfully when they hear the adjective "unique" used inthe comparative or superlative degrees. How, they lament,can anything be "more unique" or "most unique" when,by definition, the distinction of being unique guarantees

hospitable towards an industry that had suddenly dem-onstrated its ability to produce something more worth-while than just expensive play toys.

twas into this new but promising arena of combatthat Otto Timm elected to cast down his gauntlet. A fac-

tory site, adjacent to the Glendale, California Airport wasacquired, and, in September of 1928, Timm Aircraft Com-pany became a reality midst rampant but justifiable op-timism .

At this point, who could guess that, even then, ominousclouds of economic catastrophe were gathering on the hori-

that boldly breaks with accepted traditions (the para solTimm) , why not mate it with an engine that likewiseflaunts convention (the L-head MacClatchie ? That s theultimate in iconoclasm

Now , whoever heard of an L-head aircraft engine? Thiswriter certainly never did except for those less than artistic attempts from the late twenties through the mid-thirties when several hopefuls tried desperately to give wingsto various motorcycle and automobile engines. Nonetheless, the seven cylinder, 150 horsepower MacClatchiePanther appeared on the scene at this time and dared tointroduce an L-head valve concept to the field of aviation.

True , practically all automobile engines of that periodfeatured this same flat head principle, but even they converted to overhead valves in the late "forties" and early"fifties" when the insatiable demand for additional horsepower necessitated the change .

The MacClatchie valving, like all other L-heads , extracted a small penalty in volumet ric efficiency and resultant horsepower per cubic inch, still, on the plus side, it

provided smaller overall diameter (an d drag) plus far lesscostly construction and maintenance. It is estimated thatit required 400 fewer parts than similar overhead contem- poraries . And how many seven cylinder ra d ials of 612cubic inches displacement can boast a trim diameter ofonly 36 inches?

Lest there be any doubt as to the relia bility of thissimple but sturdy engine, let it be note d he r e t h a t , onNovember 15 , 1930, this MacClatchie powere d Timm, flying out of Rosamond Dry Lake, California, establishe d anew world's record for non-maintenance fl ig h ts. Thisgrueling test permitted a la n d ing every fou r hour s tochange pilots and take on fuel an d oil , however, a t no ti m ecould the engine be shut down nor even the si mp lestrepairs or adjustments be made.

This tortuous grind went on for 378 h ou rs and 48minutes , ultimately being terminated beca use of two"fouled" spark plugs. The number of la n dings tota led 97and average ground time was 10.2 mi n u tes. For the statistically minded, 18.5 gallons of oil a nd 2,717 gallons of

gasoline 7 .1 gal.lhr.) were consumed.At the conclusion of this endurance run, the aircraft,

equipped with a new Panther engine, was awarded toLeo Root, one of the three pilots who participated in the

record flight . At this late date, a rumor that refuses to dieinsists that Leo was the last pilot to fly in the endurancetest, and when it was discovered that he and the airplanehad inseparably grown together , there was little choicebut to formalize the union by awarding him the airplane .

The travels and travails of NC279V, from this pointon, would rival those of the legendary Aeneas and Odysseus . Summarily, it goes something like this: From LeoHart , she went to an unnamed brother-in-law who in turntransferred ownership to a R L. McCreery . McCreeryparted company with our heroine in 1936 or 1937, and herhistory is totally obscured from that time until she reappeared in Prescott , Arizona late 1941. We can only guessas to the doughty lady's whereabouts in this interimperiod, but her general appearance, when she surfaced inPrescott, strongly suggests that she fared not too well .

At this point, the Timm , in a partially disassembledstate, was acquired by the Prescott High School to serveas a classroom training aid. Sadly enough, this acquisitionwas accomplished for the settlement of a $150 lien plus apaltry $100 to the owner How can a virtuous lady fall solow?

The next scene in our little drama is dated 1947 andshows "279V" being purchased by agriculture pilot MackSheers of Buckeye, Arizona . Mack had gathered togetherquantities of surplus WW II aircraft and engines in whatsome have described as an aeronautical junk yard, and itwas into this ignominious scene of refuse that our proudli l l bi d itt d f h il ld

Alexander Aircraft Service located at Glendale Airport inPeoria, Arizona. Those baffiing Goddesses of Fate musthave had a hand in this. Our Timm first saw the light ofday at Glendale Airport in California - her rebirth oc-

curred at Glendale Airport in ArizonaBut whatever the mysterious and unseen forces at playhere, the visible fact was that, in the coming months andyears, many willing hands would take part in this challenging and exciting project. Keith and Jack Sheble rebuilt the fuselage, which required extensive sandblastingand welding plus the addition of replacement pulleys andcables. These two also rebuilt the MacClatchie into alike-new engine.

Only eight of these powerplants had been built, andany spare parts that had previously existed were lostforever in a warehouse fire in 1943. Cylinders had to berebored and resleeved, while parts that had to be manufactured included pistons, bearing and valves. Fortunately,truck engine valves were found which very closely approximated those of the MacClatchie .

Meanwhile, experienced aircraft restorer and mastercraftsman, Floyd Newt on (EAA 187544, lC 7777), undertook the exacting job of creating a new wing (the originalwas beyond repair). This task alone consumed 18 monthsof Floyd 's time and was, for the most part, accomplishedin his own garage.

Old timers will recognize the identification of the airfoil - a Fage and Collins #4 . This more than ample wing(8.27 lbs /ft 2) boasts a seven foot chord with one rib perfoot and nose ribs evenly spaced between main ribs .

Finally, after four years and two months of arduousbut unflagging effort, all things came together , includingan FAA inspection, and the Collegiate was ready to reclaim her rightful place in the sky . A few shots of primerand the durable MacClatchie roared to life after not having spoken for 38 years . The memorable day had arrived .Floyd and Keith gave their mount a few taxi tests in orderto familiarize themselves with the Johnson Bar and differential rudder braking system as well as the full swiveltail wheel.

The last week of June is usually a very special timefor Waco owners and admirers . The most dedicated willannually either fly drive walk or crawl to attend thegreatest gathering of meticulously restored Wacoairplanes ever to assemble on one airport. Wacos fromcoast to coast and from Canada usually make up thisawesome display each year at Hamilton, Ohio .

Beautiful Wacos flew in from such distant points asDenver Colorado; Fort Worth, Texas; New OrleansLouisiana ; Ocala Florida; Trenton New Jersey; BethelMaine ; and Rapid City South Dakota . The four-day reunion of Waco pilots started with an impromptu picnic at theHamilton Airport on Thursday evening June 28 1984 .

Friday s activities included additional arrivals of beautiful Wacos. Throughout the day another delicious bar-becue was prepared by Waco club member George Vaughnand members of his family at the Hamilton Airport . A

on Krantz's UPF-7 from Waitsfield, Vermont.

restoration and maintenance forum was conducted Fridayafternoon while sitting on the grass in t he shade of one ofHogan Air's DC-3s. This provided excellent sharing ofinformation leading to sources for critical replacementparts for Waco airplanes.

That evening, many outstanding slides of Wacos fromprevious Waco reunions, dating back to 1974 , where

shown in the refreshment hangar at the airport .. By Saturday, there was a mass of Wacos and Wacoadmirers . That evening, the annual Waco Reunion Banquet was held at the very comfortable facilities of VFWPost 1069 and was attended by approximately 230 persons.Following an excellent buffet, an outstanding programwas provided with such notable Waco personalities asCharlie Moffitt, Waco parts and service manager,Montgomery Monty Chumbley, Waco sales promotionmanager for Central and South America, and Len Povey,aerialist supreme and a member of the American Air AcesShow prior to being appointed by Generalissimo Batistato head up and reorganize the Cuban Air Force. These

persons provided a very interesting program as they related some of the many interesting past experiences oftheir lives during a very colorful period in aviation.

A special commemorative patch was awarded all pilotswho flew a Waco to this 25th Annual Reunion . Fifty-yearpins were awarded to Harmon Moss and Dick Jacksonwhose Wacos celebrated their fiftieth birthday this year.

Dick Jackson 's S3HD, the only Model D to ever be soldwithin the U. S., is also the only one known to exist today .This outstanding high-performance Waco is restored andmaintained in immaculate condition, including its original colors .

All activities on and off the airport were againadequately coordinated by Waco Club member Mike Heinsand his very unique commuter bus.

Sunday was fly-out day as the many colorful Wacostaxied out and headed for their distant homes . With the25th Annual Waco Reunion almost a memory , we findourselves eagerly anticipating next year s reunion of oldand new Waco friends .

The one and only Waco S3HD and the one and only Waco CRG.These outstanding Wacos are owned y Dick Jackson ofRochester , New Hampsh ire an d Mike and Pete Heins of Dayton ,Ohio respect ively .

ANTIQUE/CLASSICMAINTENANCE TIP

Wood Propellers: Installation, Operation MaintenanceIntegral Flange Crankshafts

Your Sen senich wood propeller was manufacturedfrom aircraft quality selected lumber . The laminationsare bonded with high-strength water-proof resorcinalglue, and were assembled under closely controlled factoryconditions . Propeller balance was strictly maintained during manufacture and verified before shipment from thefactory . Assembly of Type Certificated propeller /engine /aircraft must be accomplished by personnel holding theappropriate FAA license .

Installation of the propeller will require a front faceplate of adequate stiffness (approximately the same sizeas the propeller hu b ), a flange adapter (in some cases ), anda set of attaching bolt s of the proper length.

t can be shown th a t an engine mus t de liver it s drivingtorque to a good propeller through static friction . That is ,the force which resist s movement of the propeller hub onth e engine fl a nge is du e to compre ss ion of the wood surfaceagainst the flange . Therefore , it is important to avoidcrushing the wood. Although the drive bushings incorporated in most flanges provide a back-up system, a load willbe imposed on them only if there is a movement of thepropeller on the flange . The bu shings can carry engine

driving-torque load s for only a short period of time .Forest Products Laborator yl data for Yellow Birch

wood shows that th e optimum compression pre-load of awood propeller hub is approximately 0 .006 inch per inchof hub thicknes s ( i .e. : a propeller hub which is 1 inch thickbefore installation should be compressed 0 .006 inch to athickness of 0 .994 inch by drawing up the propeller attaching bolts ). Knowing the hub thicknes s and the number ofthreads in each inch of attaching bolt thread, it is possibleto calculate the proper additional rotation of each attach

ing bolt after the front face place, propeller , and flange(or adapter ) are snug . For example , a propeller hub whichis 4.50 inches thick should be compressed 0.006 * 4.50equals 0 .027 inches. If 1 2 inch dia. bolts are used (112-20UNF threads) , they should be turned 0.027 * 20 =0 .54 , or just over 12 revolution after the front face plate,propeller , and flange are snugged. See Table No . 1 forexamp.le s of common installations .

Generally recommended wrench torque to achieveproper hub compression against standard flanges are inTable No . 2. These torque recommendations do not consider variations of thread condition, and assume that thethreads of the bolts and in the drive bushings are cleanand dry .

INSTALLATION PROCEDURE

After study of the preceding discussion of wood propeller installation requirements and ofyour propeller assem

The tips must track within 1116 inch of each other whenthe installation is completed . Track should be corrected a tthis time by snugging up the bolts nearest the blade whichis forward . This will result in a common starting point for

all of t he attaching bolts.6 . Tighten the attaching bolts in small increments ,moving diagonally across the bolt circle . t is good practiceto check track frequently while tightening the bolts . Takecare to tighten bolts on opposite sides of the blade centerline evenly so that blade-to-blade conformity of angles ismaintained.

7. Since a small part of the wood compression i s plastic(permanent) , it is good practice to loosen the bolts , and toallow the wood to relax for an hour. Retighten following

the same procedure.8 . Install safety wire . t is good practice to wire theattaching bolts in pairs (not a continuous wire), twistingthe wire between bolt heads . 'Forest Products Laboratory , U.S. Dept. of Agriculture , Mad ison , Wiscons in .

The clean lines of this airplane inthis front view are unusual for 1927

when the airplane was built . Thephoto is from the Wally Norman collection recently donated to the EAAAviation Museum . This was anotherattempt by a well-known designer tomeet the demand for a light tran sport ,the result of the boom in aviationtriggered by Lindbergh 's successfultransatlantic flight. Answers will bepublished in the December, 1984

issue ofTHE VINTAGE AIRPLANE.The Mystery Plane for the June ,1984 issue of THE VINTAGEAIRPLANE was no mystery to H .Glenn Buffington of San Diego,California, who writes , The JuneMystery Plane is the Commercial'Sunbeam ' used by Bobbie Trout andElinor Smith in setting the first in-airrefueling record for women, 45 hours5 minutes on November 27-29 , 1929 .

t was built by the Commercial Aircraft Corp. , Van Nuys, California andwas powered with a Wright J-6 300hp engine . The girls flew it withoutthe wheel fairings during the recordflight. A first-hand account of thisrecord flight is given in ElinorSmith's book Aviatrix. Doug Roundsof Zebulon , Georgia and Dr. H . M .Richey of Waco, Texas also correctlyidentified the airplane . Note thestreamlined tube extending from theupper wing to the cabin roof , evidently the arrangement to accept thefuel into the tanks .

shows around 1930 thrilled the crowds with the grandfinales. In these, a squadron of prop planes, playing followthe leader , would power dive down and flatten out in frontof the stands one after another . As each came down withmotors racing , additional distinct sharp explosive soundsat the rate of about 100 a second would occur . They wereprobably not quite as loud as those of an aerial bomb , butthey were plenty loud .

The crowds were thrilled by this demonstration andmost of them probably thought the extra roar came fromthe motors . The pilot knew what he was producing, butcould not have explained what resulted. The early cattledrover knew how to produce the explosive bank of hisbullwhip , but could not have explained what actuallycaused it. For a while it was thought that the suddenturning of the "cracker" caused a vacuum in the air whichgave a loud bang when it came together again . Then camethe modern sonic boom.

For a while there was much fumbling in explaining itscause . A British aeronautical publication stated that twobooms occurred each time, one when the plane exceededthe speed of sound and another when it slowed down . Ihad wondered for years what caused the terrific roar ofthe early power dives . They had stopped in the '30s because adjustable propellers had slowed down the RPM ofthe motors . Then in 1966 the explanation came to me . Iwas showing a film to my students, "Approaching theSpeed of Sound," put out by the Shell Oil Co. The film

showed what caused the sonic boom graphically and withsound effects . Any object, large or small, builds up a shockwave in front of it when it exceeds the speed of sound. Itis like the wake of a boat . The volume of sound it createswhen it reaches us depends upon the size of the object. Thesmall cracker of the bullwhip produces a loud firecrackerlike sound . The sonic boom of a jet plane is like that of acannon.

Now I had it - the tips of the propellors of those earlyplanes were creating good-sized booms when they ex

ceeded the speed of sound during the power dive. Manyprobably thought that the exhausts of the motors werejust that much louder and did not notice the distinctivesharpness of the explosive sounds. t also explained whya silencer is ineffective on a high-velocity rifle - thebullet has its own explosive sound . (Could that be whatthe spectators at the Kennedy assassination heard, think-ing it was another gun over by the railway overpass? )

Having solved a problem and getting it before thepeople who wondered about it for many years (as I had) isanother thing. I sent my calculations to the head of thephysics department ofmy alma mater for verification. Thereply - Your explanation of change in character andintensity of sound of a power dive is reasonable ." Therewas no attempt to pass this information on to those whowere so thrilled years ago. Sent to a popular scientificmagazine, the reply was Irrelevant ".

I sent it to the appropriate department of another

As a resultEAA's participati on in the release of the movie has beenreduced considerably from the plans we announced previously . Because of the delayed release date it would benecessary for the EAA Headquarters stafTto initiate preparations for the premier at the same time that they arecoordinating and organizing our own 32nd Annual EAAInternational Fly-In Convention and Sport AviationExhibition . EAA Headquarters has, for that reason, withdrawn from participation in the mall exhibits and previewshowings of the movie . During this critical time period itwould be unwise to add a second major project to an already busy schedule. We have made this decision in orderto maintain the high standards EAA has become knownfor in all of its activities .

EAA 's decision to withdraw from participation in thisproject should not be construed as a reflection upon themovie or its producers. We are looking forward to seeingi t when released. Any EAA Chapter that is interested inparticipating in the opening of THE AVIATOR at localmalls is encouraged to do so .
