A type of heat treatment in which the metal is heated in a furnace until its temperature is uniform throughout. It is then removed from the furnace and quenched in cold water. When the metal is hot, ...

stress relieve

Aviation; Aeronautics

A type of heat treatment of steel. When steel parts are forged, machined, or welded, stresses are often locked in them that cause the parts to warp or break. These stresses can be relieved by heating ...

convertaplane

Aviation; Aeronautics

A type of heavier-than-air aircraft able to rise and descend vertically. The convertaplane rises vertically by using rotors similar to those on a helicopter. But, when it is in the air, the rotors ...

flying wing

Aviation; Aeronautics

A type of heavier-than-air aircraft that has no fuselage or separate tail surfaces. The engines and useful load are carried inside the wing, and movable control surfaces on the trailing edge provide ...

semirigid rotor

Aviation; Aeronautics

A type of helicopter rotor that allows the pitch of the blades to be changed by rotating the blades about their feather axis (the axis that extends along the length of the blade). The blades cannot ...

capacitor-discharge ignition system

Aviation; Aeronautics

A type of high-energy ignition system that produces a hot spark for starting a gas turbine engine. In a capacitor-discharge ignition system, electrons are stored under high voltage in capacitors. ...

Deutsch rivet

Aviation; Aeronautics

A type of hollow-shank, high-strength blind rivet. The rivet is put into the hole in the structure, and a tapered pin is driven into the hollow shank. The pin expands the rivet so serrations on the ...
