Aircraft Powerplant Outer Structures

 Aircraft Powerplant Outer Structures

               Aircraft powerplants produces the source of thrust to move the aircraft through the air, at the same time they are also the source of vibration, heat and drag forces. Powerplant Structures includes both the propeller and Engine work in combination to produce thrust. Engine provides the source of power to rotate the propeller.  Propeller is mounted at the front of the engine converts the rotatory force into Thrust in the engine.

Nacelles

Nacelles encloses the engine provide the streamline flow (uniform flow) of air over the outer surface of the engine to improve the aerodynamics of the aircraft. Protect the engine and its components during flight. Allow the proper flow air to engine for cooling and combustion.

Fire walls

Firewalls are normally located near to the engine compartment. Engine, Auxiliary power units, combustion chamber and turbine produces tremendous amount of heat which affect other aircraft component and it functionality, to protect other aircraft component from this heat effect sections of the turbine engine must be isolated from the remainder of the aircraft by means of firewalls. Firewall is used to protect the nacelle strut and systems from the exposure.

Engine Mount

Engine mount is frame structures that support the engine and connect it to the fuselage. Which are designed to distribute the weight of the engine and distribute torque and vibration generate from the engine.

Cowlings and Fairings

Cowlings and Fairings both are similar, which are removable covering for covering the portions of the airplane (Engine, Mounts and other engine components). Design to provide uniform flow of air over the engine surface improve the aerodynamics of the aircraft.
