Q

The shock struct is made up of?

A

2 scoping cylinder or tubes

17
Q

What are the two cylinders in the shocks rat called?

A

Cylinder and piston

18
Q

What happens when the cylinder and piston or assembled?

A

They form an upper and lower chamber for movement of the fluid

19
Q

Among the two chambers which one is filled with fluid in which one is filled with compressed air?

A

The lower chamber is filled with fluid while the upper chamber contains compressed air

20
Q

Is placed between the two chambers and provides a passage for the fluid into the upper chamber during compression and return during extension of the strut

A

Orifice

21
Q

Most shockstruts employ a ______ for controlling the rate of fluid from the lower chamber into the upper chamber.

A

Metering pin

22
Q

Some shock struct are equipped with _______Consisting of a recoil valve on the piston or recall tube to reduce the rebound during the extension stroke and to prevent too rapid extension of the shock struct

A

Dumping or snobbing device

23
Q

Majority of shockstruts are equipped with an ____ attached to the lower cylinder to provide for installation of the wheels

A

Axle

24
Q

Is located near the upper and of each shock strat to provide a mean of filling the hydraulic fluid and inflating it with air

A

Fluid filler inlet and air valve assembly

25
Q

Designed to seal the sliding joint between the upper and lower telescopics cylinders is installed in the open end of the outer cylinder

A

Packing gland

26
Q

Is also installed in the groove in the lower bearing or gland nut on most shockstrap to keep the sliding surface of the piston free of debris

A

Packing gland ring

27
Q

Entry of foreign matter into the packing land would result in?

A

Leaks

28
Q

To maintain correct alignment of the wheel, shockstrap without dark arms having spleen piston heads and cylinder switch maintain correctly

A

Torque arms attached to the upper and lower cylinder

29
Q

Nose gear shock strats are provided with an ____ attached to the upper cylinder and a _ ____ attached to the lower cylinder

A

1.Upper locating cam
2. Mating lower locating cam

30
Q

Prevents the nose wheel from being cocked to one side when the those gear is retracted

A

Cam line

31
Q

Generally, nose gear strut are equipped with _____ to enable quick turning of the aircraft when it is in standing idle on the ground or in the hanger

A

Locking pin

32
Q

What happens if the lacking pin is disengaged?

A

It will allow the will fork spindle to rotate 360°

33
Q

Occurs at the end of the compression stroke

A

Extension stroke

34
Q
