- Company Profile:
A precision electric motor whose output shaft position is changed in steps by pulses from the control device. Stepping motors can make high-torque changes in small angular increments to their output shaft.
Industry:Aviation
A precision measuring instrument used to measure the depth of the hone marks in the surface of a cylinder wall.
Industry:Aviation
A precision steel bar on which a propeller is mounted for balancing. The mandrel is placed across two perfectly level knife-edge plates, and the propeller is allowed to rotate until it stops with its heavy point at the bottom.
Industry:Aviation
A pressure wave that forms on a sharppointed object when air flows past it at a supersonic speed.
Industry:Aviation
A procedure in which an aircraft engine is operated on the ground to determine its condition and performance.
Industry:Aviation
A professional organization that has formulated standards for the automotive and aviation industries.
Industry:Aviation
A progressive decrease in RPOM with load in a gas turbine engine whose speed is governed with a fly-weighttype governor in the fuel control. As the load increases, the pilot valve drops down to meter more fuel. The lower position of the valve decreases the compression of the speeder spring and allows the flyweights to assume an on-speed position at a lower rpm.
Industry:Aviation
A propeller blade made from several materials such as metal, graphite, glass or aramid fibers, and foam.
Industry:Aviation
A propeller installed on an aircraft engine so that it faces the rear of the aircraft. Thrust from the propeller pushes rather than pulls the aircraft.
Industry:Aviation
A propeller that is rotated by air flowing over the blades rather than powered by the engine. work. The product of a force times the distance the force is moved.
