Jet engines

Engines that propel aircrafts by using discharged gases to produce forward thrust. The thrust is generated by jet propulsion of a rearward discharge of fluid, usually combustion gases, in accordance with Newton's laws of motion.

pressurizing and drain dump valve

Aviation; Jet engines

Device to prevent flow of fuel to the nozzle until enough pressure is built up in the fuel control. One also drains the fuel manifold at engine shutdown and traps fuel in the upper portion of the ...

primary air

Aviation; Jet engines

Air that mixes with fuel in the combustion chamber to form a combustible mixture. The ratio is 15 parts of air to 1 part of fuel.

radial inflow turbine

Aviation; Jet engines

Type of turbine made by some manufacturers, not used in any Army aircraft today, even though it is rugged and simple, relatively inexpensive, and easy to manufacture. Similar in design and ...

ram

Aviation; Jet engines

The amount of pressure buildup above ambient pressure at the engine's compressor inlet due to the forward motion of the engine through the air (initial momentum of the air).

ramjet

Aviation; Jet engines

A basic type of ram powered jet engines, consisting of three sections; an inlet to compress incoming air, a combustor to inject and combust fuel, and a nozzle to expel the hot gases and produce ...

ram air pressure

Aviation; Jet engines

Free stream air pressure, provided by the forward motion of the engine.

scramjet

Aviation; Jet engines

Mechanically similar to ramjets, scramjets consist of an inlet, a combustor, and a nozzle. The main difference between ramjets and scramjets is that scramjets do not slow the oncoming airflow to ...
