Hydraulics and Pneumatics part 2

Question 1

What type of component:

This component is the end part of the system, the component which converts the hydraulic fluid power into a mechanical force and motion

Answer 1

Hydraulic actuator

Question 2

what type of hydraulic actuator:

This actuator usually comprises a cylinder and piston operating in back and forth movement, with the cylinder being attached to part of the airframe structure and the piston to the device being operated

Answer 2

Linear actuator

Question 3

what type of hydraulic actuator:

This actuator changer linear movement of the piston into a rotary movement through teeth cut into the piston shaft and which drives a pinion in a similar manner to the rack and pinion steering mechanism of a motor car.

Answer 3

Rotary actuator

Question 4

An actuator can be locked in position, for example holding flaps at a set deflection by the action of a rotary valve. This is called?

Answer 4

Hydraulic lock

Question 5

The high pressure pneumatic system, pressure range is?

Answer 5

1 000 - 3 000psi

Question 6

The medium pressure pneumatic system, pressure range is?

Answer 6

100 - 150 psi

Question 7

The low pressure pneumatic system, pressure range is?

Answer 7

1 - 10psi

Question 8

What type of pneumatic pressure system:

The bottle is normally recharged on the ground with a compressor and with such an arrangement, this supply of air is reserved for emergency use only.

Answer 8

High pressure system

Question 9

What type of pneumatic pressure system:

This system normally do not include an air bottle. Bleed air is taken from the compressor stage of the turbine engine and lead through tubing via pressure control valves to the operating units

Answer 9

Medium pressure system

Question 10

What type of pneumatic pressure system:

This type of system is used to drive certain of the aircraft’s gyro instruments

Answer 10

Low pressure system
