Breifly discride the fuselage...what does it house? (Fixed wing) |
*This is the main body of the aircraft to which other parts of the aircraft are attached. E.g the mainplane. *It houses the remaining aircraft systems. |
MB AS |
|
|
Briefly discribe how the gas turbine engine works. What is another name for this part? (Fixed wing) |
*Draws air into itself throuh the intake *Compresses it *Adds fuel in the combustion chamber *Ignites the mixture to produce thrust. |

|
|
What are the two purposes of the lubracation system? |
*Minimise wear *Dissapate heat |
MW DH |
|
|
What is the mainplanes primary purpose? (Fixed wing) |
To provide lift and lateral stability. |
PL and LS |
|
|
What does the mainplane house? (Fixed wing) |
*The under carridge *Fuel tanks which store and deliver fuel to the engine *Can be fitted with pylons to carry wepons and stores |
UC FT P |
|
|
What is the purpose of the flaps and where are they situated? (Fixed wing) |
*They are to increase lift from the mainplane when travelling at low speeds. *Situated on the innerside of the mainplane. |
IL at low speeds .....of the mainplane |
|
|
What is the purpose of the Ailerons and where are they situated? (Fixed wing) |
*They allow the pilot to roll the aircraft from port to starboard. *they are situated on the outer side of the mainplane. |
Role ....of the mainplane |
|
|
What is the purpose of the Tailplane? (Fixed wing) |
*The tailplane provides pitch stability to atop the aircraft doing undemanded nose-up/down motions *A horizontal stabiliser |
*PS *HS |
|
|
What is the purpose of the fins? (Fixed wing) |
*Act as a vertical stabiliser *Used for directional stability by supporting the rudder. |
VS DS |
|
|
What is the purpose of the rudder and where is it situated? (Fixed wing) |
*This allows for directional control. *Situated on the fin |
DC F |
|
|
What is the fuction of the undercarriage? (Fixed wing) |
Allows the aircraft to taxi, take-off, land and brake. |
T TO L B |
|
|
What is the purpose of the cabin? (Rotary wing) |
*Acts as a seating area *Provides equiptment fits and internal cargo carrying |
SA EF CC |
|
|
What is the purpose of the tail pylon? What does it house? (Rotary wing) |
*Provides a mounting point fornthe tail rotor. *Houses the intermediate gearbox which changes the angle of drive from the tailcone to suit the tail rotor |
MP IG |
|
|
What is thr purpose of the tail cone? What does it house? (Rotary wing) |
*Extends the tail pylon so theres a clear path for the tail rotor blade. *Houses a drive shaft which transmits the rotational drive from the transmission system to the intermediate gear box. |
Extends DS |
|
|
Briefly descride the gas turbine engine... (Rotary wing) |
*Similar to that of the fixed wing however it transmits the drive to the rotor blades via a transmission system. |
Transmits |
|
|
What are the two types of main rotor head? What is the purpose and how do they work? (Rotary wing) |
*fully articulated (sea king) *semi-rigid (lynx) *Attachment for the main rotor blades. *They are attached to a rotating output shaft driven from the engines via a main gearbox and transmits the pilots control movements. |
FA SR Attachment for... ROS |
|
|
What is the purpose of the main rotor blades? |
To provide lift and thrust to counteract the drag during forward flight. |
L and T |
|
|
What is the purpose of the tail rotor blades? |
The tail rotor blades provide direcrional control, they develop thrust to counter the torque reaction created by the main rotor. |
DC Counters TR |
|
|
Flotation system purpose... |
So the aircraft can stay afloat should it be forced into the sea. |
SA |
|
|
Discribe the monocoque principle, give an example... |
*A structure with an outer skin that distrsbutes the stresses placed upon it. *An egg |
OS distrabutes S E |
|
|
Discribe semi-monocoque construction |
*A skeletal framework to strengthen the overall structure. This is cover with a stressed skin. |
SF cover with SS |
|
|
What is a frame? |
*The main structural componant which forms the cross section shape of an airframe. |
Main |
|
|
What is a longeron? |
*Mail longitudinal componant use to tie frames together. |
Tie |
|
|
What is a stringer? |
*Short and light componants which add aditional strength where needed. |
Aditional S |
|
|
What's the purpose of a bulkhead? |
*Protevtion for aircrew. *Attachment points for equiptment |
P AP |
|
|
Briefly discride the airframe of a mailplane... |
*the main lateral member is called a main spar. *The for and after members are the ribs. |
MS R |
|
|
What are zonal locations used for? |
These are used to locate equiptment and positions on airframes. |
E and POA |
|
|
What is the numbering method used for? Breifly discride how it works... |
This is used to identify: *frames - numbering from the datum, foremost frame towards the tail *ribs - lettering from the datum, where the mainplane meets the fuselage outward. |
F R |
|
|
What is the station methodnused for? Where is the datum? |
*To identify frames by their distance in mm or inchs from the datum. *Virtically in line with the main rotor head. |
F MRH |
|
|
