Analysis

Buriag this period all data reduction for Model 309A take-off and landing

taste has 'beca coaplated aad all take-off and landing teete have bsen r«plottad

for reps-eduction. Report So. 1309-9* Flight Teax Observed aad Corrected Data

Report toe been written aad is nearly reedy for releaee.

Calculations are now being aade for uee in Report Bo. 1309-IO, Flight Test

PerforHanoe Data Report, which will contain result* and analysis of take-off and

landing testa of Model 30?A.

The at>at algnlfioant iaprsveaeat in perferaance di« to boundary layer

control (K£) appeared in the reduction of air diatanoe over a 5$/-foot obstacle

during take-off. Thia haa been attributed to differencea in effect Ira thrust

(thrust sinus drag) at clinb-out speeds. For the ease with ELC operating this

speed waa lover ao tuat greater propeller thrust was developed. In addition

the phyelcal nagnitude of drag in pounds waa analler even though the drag co-

efficient with 3LC was greater. The overall effect increased the angle of

clisab-cart to the extent that substantial reduction in air distance occured.

Analysis

Tiss analysis of elevator defleetloa required to lead indicated that

considerable ao&ificatioa to a standard L-19 tail will be reoaired. The

oos$«tations skew that this present tall tau 1 aanffjciaat power to 3-polat

the earplflae vita flaps full down aad ailerons drooped. This difficulty has

been experienced vlth the Cessna Model 339&# sad is being corrected oa that

airplane ay adjustment of horisontal stabiliser incidence aad e snail Increase

la elevator area. Due to considerable issagxr pitching neaatBta e^pseted froa

the |19A K£ wtsg taa siHAgle ch«#ms «r«iaa are being ss& ts the 309 tail would

net be sufficient.

Siase the aerodynamic aad structural design of an entirely sew aorlaoatal

tail is expensive aad tine consunlng, a Ceaaaa Model l£0 variable i«eid«w«

horissntal tail was considered.. It vas found that t&* use of this tall alleviated

the prcolem considerably, and steps are underway to incorporate it oa the 319*.

Svt>n vita this improved tail it may bacons necessary to add elevator zsm. aad

Impose nev limitations on the forward center of gravity location. These factors

will he resolved during preliminary flight testa.

Ifc should he noted that all computations have been based upon the standard

question exists aa to the validity of these charts for wings developing the

high lift coefficients associated vlth ELD (or circulation control); therefore,

Propellers

Final arrangements for the delivery of two propellers has bees cornpieted

vlth Hartsell Fropeller Company, Piqua, Ohio. Both propellers are to be flight

tested sad one returned without cost. Deliver/ to Cessna .'s scheduled for the

week of 13 July, 1953.

Miscellaneous

Plans for beach tests of various ssthods for Bl£ power transmission,

other than hydraulic, have been altered considerably since the time of last

reporting. The electrical system has been abandoned after discussion by

Cessna personnel vlth Major J. Willcox (OUR), Mr. R. Putnas and W, J. Bsaeh

(Office ©f the Chief of Transportation, U.S. Army), ^he development cost of

the solid propellent system proposed by General Electric Company exceeds the

financial limitations of the present contract. Therefore the following companies

were invited to make proposals of solid and liquid propellent gas generator

systems utilizing existing turbine wheels %

AlReseareh &fg. Co., Los Angeles, California Turbo Products Inc., Faeoima, California AaroJet-General Corp., Axusa, California Reaction Motors, Inc., Dover, Hew Jersey

Preliminary survey Indicates that several light weight, compact package-

power units have been developed for missile application. I'; is possible that

at least two ess be adapted to our needs as turbo-fan unite.

Personnel

During this period three additional engineers have been added to the

analysis section. Their full time activities will be devoted to the Cessna

Models 309c (hydrogen peroxine Jet r'Jap) And 319A-- Education and experience

of each man is as follows»

Trips

Mr* A. S. Petroff and Mr. J. W. Fisher visited Washington, D.C. on June

23 and 2V, 1953. The purpose of the trip was to attend the IAS symposium on

boundary layer control held the 2Uth. In addition, an June 23rd a conference

was conducted at the sffioes of the U.S. Army Chief of Transportation. Attend-

ing, in addition to Cessna personnel, were;

Major J. Wiliocx, ONR „ < K. Putnam, U.S. Army Mr. J. Beach, U.S. Army Mr. K. Rasak, UaiYeraity of Wichita

Mr. Putaarn and Mr. Beach disclosed a plan for am orientation lecture to

he presented before Army personnel at sows date prior to demonstration of the

319A. This met with agreement by Cessna, and the lecture d»te will be estch-

listed when a firm initial flight date is known. It was fslt that the time

period between lecture and demonstration should be as short as possible. Final

delivery date of all purchased parts fixes the initial flight date, and It is

expected to be established by the week of July 20, 1953,
