1/2 inch

1/8 inch

1 inch

3) Acoustic linings made from composite materials are used in what section of the engine? Report

Cold section only

Hot section & Cold Section

Not used to suppress noise

4) Vibration mounts are used for Report

stopping vibrations entering the engines

preventing engine vibration loads being transmitted to the airframe structure

damping out vibration stresses on engine when being transported on an engine stand

5) An aircraft has a heavy landing and on inspection of the engine mounting bolts the bolts torque loading has reduced, you should Report

add washers to take up any gap or slackness and re-torque to correct value

remove bolt and carry out inspection as the bolt may have increased in length due to heavy landing

re-torque bolt up to correct torque value

6) Forward engine mounts take which loads? Report

Thrust, vertical and shear loads

Centrifugal, thrust and axial

Thrust, vertical and impact

7) Forward engine mounts take which form? Report

Castings

Forgings

Fabricated sheet steel

8) Pipes around engines are Report

aluminium

mild seamless steel

stainless steel

9) Fibrous metallic lining for noise suppression is used Report

in cold area

in hot area

for lobe type noise suppressors

10) Noise lining in the fan area is made from Report

layers of bonded resin

felt with aluminium sheet

porous type Honeycomb and backing sheet

11) A powerplant consists of Report

a basic engine plus E.C.U

a basic engine plus thrust reverser, exhaust system and gear box with accessories

the complete engine as it would be found on aircraft including all connections, controls, cowlings, intake etc

12) Acoustic blankets are installed to Report

reduce noise levels

increase thermal efficiency

aid the streamlining of the engine

13) When checking the effect of inertia on the engine after heavy landing you would first check the Report

thrust line

module alignment

compressor shaft for distortion

14) Following the reports of a heavy landing you would Report

carry out a complete visual examination of the power plant

examine the engine mountings and borescope the nozzle guide vanes and turbine

examine the engine mountings and fuse pins

15) The purpose of spring back and cushion on an engine power lever is Report

used when friction builds up in a system

used to prevent the controls hitting the fuel control stops

used when full travel is used but slight movement is still required on the fuel control unit

16) What are sometimes installed in an engine mounting system to tune out the worst engine vibrations? Report

Spring cushioned mounting pads

Vibration absorbers of calibrated weight

Rubber encased wire-mesh vibration isolators

17) Where are the lifting points on a high bypass turbine engine? Report

On the fan and compressor casing

On the fan and turbine casing

On the fan, turbine and compressor casing

18) Rubber anti-vibration pads are fitted to engine Report

components to prevent fatigue

cradles to prevent damage during transportation.

pylons to prevent vibration through the airframe.

19) Engine thrust is transmitted through mountings that Report

are designed to transmit eng thrust equally through front and rear supports

are designed to prevent the thrust line of the engine varying

allow for radial and axial expansion

20) If you reduced the length of bellcrank (2) what would happen to the input to the F.C.U? Report

Reduce

Increase

remain the same
