Splines --  teeth in a gear.   Stable operation --  condition where no appreciable fluctuation, intentional or unintentional, is occurring to any of the engine's variables such as RPM, temperature, or pressure.   Standard day conditions --  59o F, sea level barometric pressure (29.92 inches of mercury).   Static-balanced surface --  surface that is in balance about its hinge axis.   Stator --  part of assembly that remains stationary with respect to a rotating part. Stator vanes are a stationary set of airfoils in a compressor.   Stress --  resultant condition of strain or pressure. 
 

 
 
飞机发动机术语英文解释(T-V)
 

 

Tachometer generator --  device that supplies power at a frequency proportional to the driven speed which drives the synchronous motors in the indicator.   TBO --  time between overhauls. This is established by the Army and the engine manufacturer.   Test cell --  building, usually concrete, that contains both a control room and an engine room, used for testing engines. The test cell is at the manufacturer's; a mobile engine-test unit is used in the field.   Thermodynamic cycle --  succession of processes which involve changes in temperature, pressure, and density in which the substance acts as a means of transformation of energy. See Otto and Brayton cycles.   Thrust --  a reaction force in pounds.  
 

 

Thrust, gross --  the thrust developed by the engine, not taking into consideration any presence of initial-air-mass momentum.   Thrust, net --  the effective thrust developed by the engine during flight, taking into consideration the initial momentum of the air mass prior to entering the influence of the engine.   Thrust, reverser --  a device used to partially reverse the flow of the engine's nozzle discharge gases and thus create a thrust force in the rearward direction.   Thrust, specific fuel consumption --  the fuel that the engine must burn per hour to generate 1 pound of thrust.   Thrust, static --  same as gross thrust without any initial airmass momentum present due to the engine's static condition.   Torque --  a force, multiplied by its lever arm, acting at right angles to an axis.   Torquemeter --  hydromechanical torque-measuring device located in the reduction-gear section of the inlet housing. The measurement is read as torque oil pressure in psi.   Torquemeter indicating system --  pressure indicator for continuous readings of engine output-shaft torque.   Transient conditions --  conditions which may occur briefly while accelerating or decelerating or while passing through a specific range of engine operation.   Turbine nozzle --  stationary nozzle which discharges a jet of gas against the blades on the periphery of a turbine wheel.   Turbine rotor --  rotating portion of a turbine engine. It is made of specially alloyed steel because of severe centrifugal loads, the result of high rotational speeds.   Turbine section --
