RADIAL ENGINE

The #adial ngine is a reciprocating type internal combustion engine configuration in

which the cylinders point outward from a central crankshaft like the spokes on a wheel.This type

of engine was commonly used in most of the aircrafts before they started using turbine engines.

In a #adial ngine, the pistons are connected to the crankshaft with a master


9/74

piston on its power stroke and the ne3t piston on fire(the piston on compression!. If an even

number of cylinders was used the firing order would be something similar to 5,6,A,E,9,:,C,L,F,57

which leaves a three

FIGURE SHO,ING MASTER ROD

$.1.$ CONNECTING ROD#

In a reciprocating piston engine, the nne*ing +d or n+d connects the piston to

the crank or crankshaft. Together with the crank, they form a simple mechanism that converts

linear motion into rotating motion.

'onnecting rods may also convert rotating motion into linear motion. +istorically, before the

development of engines, they were first used in this way.

$s a connecting rod is rigid, it may transmit either a push or a pull and so the rod may rotate

the crank through both halves of a revolution, i.e. piston pushing and piston pulling. arlier

mechanisms, such as chains, could only pull. In a few two


11/74

#adial engines typically have a master rod for one cylinder and multiple slave rods for all the

other cylinders in the same bank.

$.1. PISTON#

$ /is*n is a component of reciprocating engines, reciprocating pumps, gas

compressors and pneumatic cylinders, among other similar mechanisms. It is the moving

component that is contained by a cylinder and is made gas


12/74

The gap in the piston ring compresses to a few thousandths of an inch when inside the cylinder

bore.

The split piston ring was invented by Dohn #amsbottom who reported the benefits to

the Institution of *echanical ngineers in 5FAC. It soon replaced the hemp packing hitherto usedin steam engines. The use of piston rings at once dramatically reduced the frictional resistance,

the leakage of steam, and the mass of the piston, leading to significant increases in power and

efficiency and longer maintenance intervals.

$.1. PISTON PIN PLUG#

The piston pin plugs are placed as a cap over the pistonRgudgeon pin locking them in the

cavity of the piston and connecting rod. They are placed on both the sides of the gudgeon pin of the piston connecting rod assembly i.e., each cylinder contains two piston pin plugs.

The piston pin plugs keep the gudgeon pin centered within the cylinder diameter, without

damaging the cylinder walls (itBs softer!. In the absence of the piston pin plug, the piston pin

wobbles a little up and down with each stroke. The wobbling gets worse and worse, till the pin is

able to roll over in itBs cavity in the piston. >hen it starts to roll over, nothing stops it, and it can

turn whichever way it wants. Invariably, it beats itBs way out through the piston skirt, and is now

floating around in the crankcase. Thus the piston pin plug plays a very vital role in keeping the

gudgeon pin in its place without any wear and tear.

$.1.2 MASTER ROD BUSH#

$ ('s&ing or +'((e+ ('s&ing is a type of vibration isolator; It provides an interface

between two parts, damping the energy transmitted through the bushing. $ common applicationis in vehicle suspension systems, where a bushing made of rubber (or, more often, synthetic

rubber or polyurethane! separates the faces of two metal obects while allowing a certain amount

of movement.

12

http://en.wikipedia.org/wiki/Suspension_(vehicle)http://en.wikipedia.org/wiki/Suspension_(vehicle)http://en.wikipedia.org/wiki/Synthetic_rubberhttp://en.wikipedia.org/wiki/Synthetic_rubberhttp://en.wikipedia.org/wiki/Polyurethanehttp://en.wikipedia.org/wiki/Polyurethanehttp://en.wikipedia.org/wiki/Suspension_(vehicle)http://en.wikipedia.org/wiki/Synthetic_rubberhttp://en.wikipedia.org/wiki/Synthetic_rubberhttp://en.wikipedia.org/wiki/Polyurethane


13/74

This movement allows the suspension parts to move freely, for e3ample, when traveling

over a large bump, while minimizing transmission of noise and small vibrations through to the

chassis of the vehicle. $ rubber bushing may also be described as a 3le4i(le )'n*ing or an*i

5i(+a*in )'n*ing.

The master rod bush is placed centrally in the cavity provided in the model to avoid the

vibrational and torsional damping caused due to the continuous movement of the engine. It helps

in avoiding the wear and tear of the master rod by decreasing the vibrational energy.

$.1.6 ROD BUSH UPPER#

The connecting rod consists of two ends i.e., the bigger and the smaller ends. These ends

connect the connecting rod to the cylinder and the master rod of the radial engine respectively.

The upper end of the connecting rod is fitted with a bushing according to its size. The

bushing helps to decrease the damping effect due to the continuous motion of the connecting rod.

The bushing encases the gudgeon pin which connects the connecting rod with the piston.

The upper end of the connecting rod is connected to the piston by the piston pin. If the

piston pin is locked in the piston pin bosses or if it floats in both the pistonand the connecting

rod, the upper hold of the connecting rod will have a solid bearing (bushing! of bronze or similar

material. $s the lower end of the connecting rod revolves with the crankshaft, the upper end is

forced to turn back and forth on the piston pin. $lthough this movement is slight, the

bushing is necessary because of the high pressure and temperatures. If the piston pin is semi

floating, a bushing is not needed.

$.1.7 ROD BUSH LO,ER#

The lower end of the connecting rod connects the piston to the camor to the master rod in

case of a radial engine. %ue to the rapid motion of the connecting rod the vibrational and

damping effects produced in the connecting rod have to be reduced in order to obtain the smooth

working of the engine. +ence the lower end of the connecting rod is fitted with a bush.

The lower rod bush is used to decrease the damping effect in order to obtain efficient

functioning of the engine. It is made of various materials depending upon the type of engine

being used.

The upper end of the connecting rod is connected to the piston by the piston pin. If the piston

pin is locked in the piston pin bosses or if it floats in both the piston and the connecting rod, the

upper hold of the connecting rod will have a solid bearing (bushing! of bronze or similar

material. $s the lower end of the connecting rod revolves with the crankshaft, the upper end is

forced to turn back and forth on the piston pin. $lthough this movement is slight, the

bushing is necessary because of the high pressure and temperatures. If the piston pin is semi

floating, a bushing is not needed.

15/74

$.1.8 LOC9 PIN#

The connecting or the articulated rods of the radial engine are connected to the main hub of

the master rod in the radial engines. This is done with the help of the lower ends of the

connecting rods having cavities placed in alignment with the cavities on the master rod and then

locking them using a bolt.

The bolts or the pins which are used to lock the connecting rods with the master rod hub are

called the lock pins. They restrict the movement of the connecting rods, thus fi3ing themselves to

the hub for the efficient functioning of the engine.

The lock pins pass through the lower rod bush thus recieving less damping effect. Thus the

lock pins are helpful in restricting the degrees of freedom of the connecting rod.

$.$ HO, A RADIAL ENGINE ,OR9S#

The radial engine is a reciprocating type internal combustion engine configuration in

which the cylinders point outward from a central crankshaft like the spokes on a wheel. This

configuration was very commonly used in large aircraft engines before most large aircraft

started using turbine engines. In a radial engine, the pistons are connected to the crankshaft

any time during the product development process and automatically update downstream

deliverables. This capability enables concurrent engineering design, analysis and manufacturing

engineers working in parallel and streamlines product development processes.

$lmost thirty five years, ro ngineer has been the most powerful and popular

three dimensional computer aided design software in the industry. It has the most variety in terms

of advancement in product development capabilities that are currently available on the market.

The current version of ro ngineer is simple to use and learn. It is also very affordable, no

matter whether you have small or medium size company.

-asically, it has every functionality that a small business re0uires to be successful.

There are many client testimonials that provide product feedback. This is very important because

it is always good to hear it straight from your peers. *any people who represent the small

business sector were recently asked about why they used this particular '$% software.

The testimonials were located in various countries and represented various

industries, too. They e3plained how the software provided a positive impact on their operations

and the feedback was 0uite comprehensive. $lmost everyone has business operations that

involve daily tasks, including product design. ome types of proects and product design include

the creation of an overall design for the primary components. This is an assembly type that could be assisted by the ro ngineer program.

)nce you have created the digital model you may need to apply plastics on the

form. The software allows you to create the styling and surfacing as it is able to simulate the

characteristics of different materials. This step will then drive the design for all the product sub<

components. The pro ngineer software allows you to drive the complete design from a single

primary file. >hen this product is used, be sure to be aware of the specifications and references

in the very beginning of the proect.

If changes need to be made, the software can do it automatically. -oth the

measurements and the design of the components can be altered according to your desire. This

creates very big opportunities for time saving processes, which is why this software program is

27

28/74

such a powerful tool. >ithout the ability to make changes so easily, you would have to make

drafts for every component on an individual basis.

If for e3ample the complete dimensions of your design change, some types of

software would force you to change each individual component where asro ngineer allows

you to change all the units and measurements easily in one go.

It can also be used for production. >hen three dimensional files are sent to a

manufacturer, they can construct the tooling straight from the files that were sent. ince the file

is 6% and it has all the necessary measurements, it can save you from the task of needing to

create the two dimensional sketches that the manufacturer used to have to have in order to review

the part.

2ou can easily make call outs to the important measurements that you want them

to perform total analysis on. This is a real time saver. In fact, it can save about twenty per cent of

the time that you would generally spend on the whole process.

If you need a powerful solution for your product development process, ro

ngineer is a good choice, as it allows you to work more efficiently and with improved design

verification.

tructural analysis is probably the most common application of the finite element

method. The term structural (or structure! implies not only civil engineering structures such as

ship hulls, aircraft bodies, and machine housings, as well as mechanical components such as

pistons, machine parts, and tools.
