Centrifugal-axial flow compressor -- combination of the centrifugal-flow and the axial-flow
compressors. It usually consists of a five- or seven-stage axial-flow compressor and one
centrifugal-flow compressor. Also called the dual compressor.
Centrifugal-flow compressor -- one with an impeller (rotor), stator, and compressor manifold. The rotor
revolves at high speed, drawing air into the blades. Centrifugal force accelerates the air, and it
moves through the stator and through the manifold.
Combustion -- process of burning the fuel-air mixture in a gas turbine engine.
Combustion chamber -- part of a turbine engine in which the propulsive power is developed by
combustion of the injected fuel and the expansive force of the resulting gases.
Combustion chamber liner -- engine part usually constructed of welded high-nickel steel, subjected to
flame of extremely high temperature. It is behind the compressor and receives the compressed
air which is mixed with fuel and ignited. The combustor is where the combustion takes place.
Combustor -- the combustion chamber of a gas turbine engine with its associated burners, igniters, and
Compressor -- that section of an engine that produces an increase in air pressure. It is made up of
rotating and stationary vane assemblies. It is the gas producer, or it may be thought of as an air
Compressor rotor -- impeller, may be thought of as an air pump. It accelerates the air rearward into the
first stage vane assemblies.
Compressor stall -- separation of the airflow from the suction surface of the fixed or rotating blades of a
compressor. Any degree of stall reduces airflow.
Concave -- pressure side of an airfoil.
Conduction -- transfer of heat through material by communication of kinetic energy from particle to
particle rather than by a flow of heated material.
