What are the 4 factors of an aircraft?

*sufficiently strong


*not excessivly heavy


*provide adequate mounting for wepons and equiptment


*streamlined and compact

SS


NEH


PAMFW


SC

Breifly discribe the cockpit/flight deck including location and 2 things you can see from this area.

*An area where the pilot controls the aircraft.


*Fuel contents, flight controls, navigation instraments...

Pilot


FC FC NI

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.

Draws


Compresses


Adds


Ignites to produce...

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

What is the waterline method used for? Where is its datum?

*used to identify longerons by their distance in mm and inches from datum.


*horizontally in line with the deck of the cabin
