• constant-speed propeller — A propeller in which the pitch is adjusted automatically, so that the propeller revolves at a given rate dictated by the pilot and remains at that rate irrespective of maneuvers or throttle position. The pitch of the propeller is altered suitably …   Aviation dictionary

• Constant Speed Drive — Mechanism CSDs are mainly used on airliner and military aircraft jet engines to drive the alternating current (AC) electrical generator. In order to produce the proper voltage at a constant AC frequency, usually 3 phase 115 VAC at 400 Hz, a… …   Wikipedia

• constant-speed unit — An engine driven unit used for variable pitch propellers. A CSU automatically permits adjustment of the pitch for varying the speed and power. This allows the propeller to operate more efficiently at any selected combination of RPM, manifold… …   Aviation dictionary

• Propeller — A propeller is essentially a type of fan which transmits power by converting rotational motion into thrust for propulsion of a vehicle such as an aircraft, ship, or submarine through a mass such as water or air, by rotating two or more twisted… …   Wikipedia

• Propeller governor — History = In the history of development of the airplane it became apparent that it is necessary to improve aircraft performance. One of influential factors was the propeller design in relation to the most efficient blade angle. The first… …   Wikipedia

• Controllable pitch propeller — A controllable pitch propeller (CPP) or variable pitch propeller is a type of propeller with blades that can be rotated around their long axis to change their pitch. If the pitch can be set to negative values, the reversible propeller can also… …   Wikipedia

• controllable-pitch propeller — A propeller whose pitch can be altered by the pilot in flight. Unlike in a constant speed propeller, where the governor automatically controls the pitch, here the pilot carries out the pitch adjustments. Takeoff is made with a low blade angle, so …   Aviation dictionary

• Constant-velocity joint — Rzeppa six ball CV joint Constant velocity joints (aka homokinetic or CV joints) allow a drive shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction or play. They are mainly… …   Wikipedia

• propeller governor — A device that keeps the propeller speed constant irrespective of the forward speed and power. The governor is usually centrifugal and keeps the shuttle valve oscillating about the null position feeding oil to change the propeller pitch and thus… …   Aviation dictionary

• Controllable Pitch-Propeller — Ein Verstellpropeller Verstellpropeller sind Propeller, bei denen der Einstellwinkel der Propellerblätter variabel ist, wodurch der Anstellwinkel der Blätter an verschiedene Betriebssituationen angepasst werden kann. Verstellpropeller kommen als… …   Deutsch Wikipedia
