The time it takes the engine to accelerate and give the required power increase.Aerodynamic drag --force which thrust must overcome to move an aircraft forward. Design can lesson aerodynamic drag through streamlining. Drag increases with increased speed.Airbleed actuator --device that operates the interstage bleed system, to improve compressor acceleration characteristics by unloading small amounts of compressed air.Air density--total mass of air per given volume, the weight of a given volume of air. Air is denser at lower altitude, at lower temperature, and lower humidity.Airfoil profile --outline of an airfoil section.Airfoil section --cross section of an airfoil parallel to a specific reference plane.Air-fuel ratio --Ideal mixture of 15 parts of air to 1 part of fuel by weight; the mixture to be burned in the combustion chamber.Air inlet --large, smooth aluminum or magnesium duct at mouth of engine which conducts air into the compressor with minimum turbulence and restriction.Aluminum alloy --any of a variety of alloys formed by combining commercially pure aluminum with other metals or materials such as copper, silicon, manganese, magnesium, and zinc. These alloying agents maybe added singly or in combination to produce a metal with desired characteristics or strength, heat resistance, corrosion resistance, and the like. Both wrought-and cast-aluminum alloys are widely used in the manufacture of rotor blades and aircraft propellers.Ambient --condition of atmosphere existing around the engine, such as ambient pressure or temperature.Annular combustion chamber --two-part combustion chamber made up of an annular liner and a housing assembly. The compressed air goes into a ring-shaped space formed by the annular liner around the turbine shaft rather than into individual combustion chambers. The space between the outer liner wall and the housing assembly allows the flow of cooling air. Used with axial-flow and dual compressors.Annular reverse-flow engine --type of gas turbine engine most commonly used in Army aircraft. Airflow direction is reversed in the combustion area.Anti-icing system --device that supplies hot air under pressure to prevent icing of the inlet housing areas and inlet guide vanes. Hot scavenged oil is also circulated through internal passages in the walls and struts.Army Spectrometric Oil Analysis Program (ASOAP) --periodic oil analysis for microscopic metal particles. This takes place at an oil analysis laboratory.Atmospheric pressure --barometric pressure exerted by the atmosphere as a result of gravitational attraction above the point in question.Atomizer --nozzle that creates minute particles and accurately shaped spray of fuel suitable for rapid mixing and combustion.Axial-flow compressor --one in which the air is compressed parallel to the axis of the engine.

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.Centrifugal twisting movement --force that tends to streamline rotating blades with the plane of rotation.Choked nozzle --a nozzle whose flow rate has reached the speed of sound.Chord line --imaginary line drawn between the leading and trailing edges of an airfoil.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.Compressibility effects --the phenomenon encountered at extremely high speeds (near the speed of sound) when air ceases to flow smoothly over the wings (or blade) and piles up against the leading edge, causing extreme buffeting and other effects.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 pump.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 freed 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.Convergent area --place where the cross-sectional area of a duct becomes smaller.Convergent exhaust duct --duct used on fixed-wing aircraft; formed by tapering toward the rear of the duct.Convex --suction side of an airfoil.Crossover tube --duct carrying flame to the individual cylindrical liners of thecan-annular combustion chamber.飞机发动机术语英文解释(D)Diffuser --aft structural member of an engine. It receives high velocity air from the centrifugal impeller and decreases velocity and increases air pressure. In the combustor, a diffuser forms a divergent flow path for the exhaust gases.Diffusion --process by which gases intermingle as the result of their spontaneous movement caused by thermal agitation.Directional references --specific definitions of terms referring to gas turbine engines to identify front and rear, right and left, bottom and top.Divergent area --place where air flows from a smaller into a larger area.Divergent exhaust duct --used on helicopter. Device to diffuse the exhaust gases rearward and to eliminate thrust.Drag parasite --drag caused by any member or structure which does not contribute to lift, such as engine cowlings.Drag profile --friction resistance produced by a member moving through the air; in simple terms, the "stickness" of air against the surface of an airfoil.Dry-cleaning solvent --cleaning compound that maybe used for all metal parts.Dry-sump engine --one in which the oil is stored separate from the engine.Dual compressor --see centrifugal-flow, axial-flow compressor.Duplex nozzle --dual-orifice channel through which highly atomized and accurately shaped sprays of fuel go into the combustion chamber.Dynamic load --load on an aircraft due to a dynamic force.飞机发动机术语英文解释(E)Effective angle of attack --that part of a given angle of attack that lies between the chord of an airfoil and a line representing the resultant velocity of the disturber airflow.End play --longitudinal back-and-forth play of a shaft.Engine airflow path --route of the airflow through the engine.Engine oil pressure indicating system --device that gives continuous readings of engine oil pump pressure in psi.Engine oil temperature indicating system --device electrically connected to the 28 VDC system which transmits temperature readings to the indicator in degrees centigrade.Engine speed notation --the capital letter N, which represents the rotational speed of the engine. When a number is placed after the N (as in "N1"), it indicates a specific system on the engine.Engine stations --specific locations on the engine designating temperature orpressure-measuring locations. For example, T3 means the third temperature pickup on the engine.Engine surge --result of compressor stall. The complete engine in stall.Exhaust --hot gases discharged from the engine through the exhaust diffuser section.Exhaust diffuser --section composed of an inner and outer housing, separated by hollow struts across the exhaust passage. It forms a divergent flow path for the exhaust gases.Exhaust gas temperature indicator --sensitive millivoltmeter calibrated in degree centigrade, activated by an electrical force generated by its thermocouple.飞机发动机术语英文解释(F)Feedback --relay through the controls of aerodynamic forces exerted on the control surfaces and felt by the pilot.Fir tree mount --manner of attaching the blades to the disk in the turbine rotor assembly. The root of the blade where it is attached to the disk is shaped like a fir tree.Foreign object --any object such as a tool, piece of equipment, engine part (nut, bolt, lockwire) that could in any way damage the engine.Foreign object damage --commonly called FOD, harm or destruction to the turbine engine caused by foreign objects sucked into the inlet area of the engine with the required air.Forged --shaped by hammering. Only the malleable metals are worked successfully. The application of heat increases plasticity.Free-power turbine engine --the turbine engine used by the Army. Sixty percent of the energy produced by combustion is extracted by the gas producer turbine to drive the gas producer rotor. The rest of the energy is converted to shaft horsepower to drive the output shaft of the engine.Frictional loss --resistance to the relative motion of air flowing along a duct.Frontal area --front part of a gas turbine engine, smaller than that of a reciprocating engine, therefore producing less drag.Front of engine --end from which power is extracted. An exception is the T73 engine on the CH-54, in which the power is extracted at the end where the exhaust gas is expelled.Fuel-air ratio --see air-fuel ratio.Fuel atomizer --see atomizer.Fuel controls --devices to control fuel flow. They are usually hydromechanical and include speed governors, servo systems, valves, metering systems, and sensing pickups.Fuel divider --device that meters fuel to the engine nozzles according to a predetermined schedule of secondary flow versus primary flow.Fuel nozzle --device to inject fuel into the combustion chamber in a highly atomized and accurately shaped spray.Fuel pressure indicating system --device that gives continuous readings in psi of fuel pressure in the main fuel supply line.飞机发动机术语英文解释(G-I)Gas producer--the compressor in a free-power turbine engine.Gas turbine engine --aircraft power plant that is adaptable for both airplanes and helicopters.Gerotor pump --modified gear-type pump with two moving parts, an inner toothed element and an outer toothed element. The inner one has one less tooth than the outer.Glow plug --device that consists of a heating element in a short conventional-looking spark plug.Ground angle --angle between the wing chord and the horizontal plane when the airplane is at rest on the ground.Heat exchanger --fuel-oil cooler, to help cool the oil. The exchanger is a cylindrical oil chamber surrounded by a jacket through which the fuel passes. Heat from the oil is transferred to the fuel by conduction.Hot start --overtemperature during starting.Hung start --failure to reach normal idling RPM during starting.Igniter plugs--spark plugs which function only during starting and cut out of the circuit as soon as combustion is self-supporting.Imbalance --uneven distribution of weight resulting in rotating parts being out of balance.
