  • 1

    Diffuser It is a divergent shape located between compressor and combustion chamber

    used to decrease the velocity of the air.

  • 2

    Compressed air is mixed with fuel,

    in the combustion chamber

  • 3

    Over rich mixture will produce

    exhaust smoke and carbon particles formed inside combustion chamber

  • 4

    The method used a network of passages between two laminated skins forming the flame tube is

    a transpiration cooling.

  • 5

    The purpose of dilution zone in the combustion chamber is

    to protect combustion chamber from melting

  • 6

    The overall fuel/air ratio entering combustion chamber is approximately

    (45:1 – 130:1)

  • 7

    Reverse Flow Combustion is best suited for

    turbo-prop and turbo-shaft engines

  • 8

    Combustion in Multiple-can Combustion Chamber occurs in

    two cans by igniter plugs then moved through interconnector tubes to the remaining cans

  • 9

    Compressor outlet and the duct at the forward part of the combustion is

    snout shape

  • 10

    Another name for can – annular combustion chamber is.

    A tubo-annular.

  • 11

    Can-annular compared to a multiple can design is

    smaller and lighter

  • 12

    Rich mixture that has

    too much fuel for the primary air in the combustion chamber

  • 13

    The best ratio of air fuel mixture within

    the primary dilution zone is 15:1

  • 14

    The primary condition that are necessary for safe and correct combustion

    is correct mixture ratio and air velocity must be slow enough

  • 15

    can annular combustion chamber

    has a set of flame tubes with common outer casing

  • 16

    Annular combustion chamber disadvantages

    Removal difficult and time consuming

  • 17

    Annular combustion chamber advantages

    Better thermal load distribution for the turbine

  • 18

    Swirl vanes cause

    air flow vortex and help air fuel mixing

  • 19

    Combustion stability means

    smooth burning coupled with ability to remain alight over a large range of air fuel ratio and air mass flow
