Aircraft Systems Part 1(Undercarriage, Wheels & Tyres) Flashcards
related to the bungee chord undercarriage mechanism:
The system is not damped in any way and there is a natural -
tendency for the aeroplane to bounce up and down
The type of undercarriage that is also susceptible to bouncing upon landing?
Spring steel
related to the oleo, which chamber holds the hydraulic fluid?
The lowest chamber
Related to the oleo, nitrogen is held in the -
upper chamber
the part of the oleo that determines the leg extension length?
The nitrogen filled chamber
The component that limits the oleo from rotating?
Torque links
What is this effect called?
A vibration which may occur if the wheel oscillates either side of centre during the ground roll, or taxi.
Shimmy
The device used to limit shimmy?
Shimmy dampers
when more than two wheels are attached to one support, it is known as?
Bogie
The 3 types of gear retraction systems
Hydraulic
Electric
Pneumatic
What is the name of the safety switches to prevent accidental retraction of the undercarriage while on the ground?
Squat switches
What type of nosewheel steering:
in this system, the nosewheel fork has complete freedom of movement in the rotational plane. Steering is accomplished by use of differential braking.
Castoring nosewheel
Aeroplane wheels are usually made of either -
an aluminium or magnesium alloy
What type of wheel:
The construction of this wheel is similar to that of a motor car, in that it is made from one piece and the tyre has to be forced over the rims when it is fitted. They are used on some light aeroplanes.
Well base or drop centre wheel
What type of wheel:
This type of wheel is the most commonly used wheel on both large and small aeroplanes, because the wheel can be split into equal halves, thus allowing easier removal and installation of the tyre
Divided wheels
