bell mouth inlet duct
Aviation; Aircraft maintenance
A form of convergent inlet-air duct used to direct air into the compressor of a gas turbine engine. It is extremely efficient, and is used where there is little ram pressure available to force air ...
internal-combustion engine
Aviation; Aircraft maintenance
A form of heat engine in which the fuel and air mixture is burned inside the engine to heat and expand the air so it can perform useful work.
external-combustion engine
Aviation; Aircraft maintenance
A form of heat engine in which the fuel releases its energy outside of the engine. This released heat expands air which is used to perform useful work. Steam engines are a popular type of external ...
reaction engine
Aviation; Aircraft maintenance
A form of heat engine that produces thrust by heating a mass of air inside the engine and discharging it at a high velocity through a specially shaped nozzle. The amount of thrust is determined by ...
rotating combustion (RC) engine
Aviation; Aircraft maintenance
A form of internal combustion engine in which a rounded, triangular-shaped rotor with sliding seals at the apexes forms the combustion space inside an hourglass-shaped chamber. Expanding gases from ...
residual magnetic particle inspection
Aviation; Aircraft maintenance
A form of magnetic particle inspection for small steel parts that have a high degree of retentivity. The part is magnetized, removed, and inspected away from the magnetizing machine.
rocket engine
Aviation; Aircraft maintenance
A form of reaction engine whose fuel and oxidizer contain all of the oxygen needed for the release of heat energy. The released heat expands the gases which are ejected at a high velocity from a ...
