The propellers of a C-130J Super Hercules military transport aircraft. In aeronautics, an aircraft propeller, also called an airscrew, [1] [2] converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards.
Contra-rotating propellers Contra-rotating propellers on the Rolls-Royce Griffon-powered P-51XR Mustang Precious Metal at the 2014 Reno Air Races. Aircraft equipped with contra-rotating propellers (CRP) [1] coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston engine or turboprop engine to drive a pair of coaxial propellers in contra ...
A constant-speed propeller is a variable-pitch propeller that automatically changes its blade pitch in order to maintain a chosen rotational speed, regardless of the operational conditions of the aircraft. This is achieved by use of a constant-speed unit (CSU) or propeller governor, which automatically changes the propeller's blade pitch.
A pusher aircraft is a type of aircraft using propellers placed behind the engines. Pushers may be classified according to lifting surfaces layout (conventional or 3 surface, canard, joined wing, tailless and rotorcraft) as well as engine/propeller location and drive. For historical interest, pusher aircraft are also classified by date.
An advanced type of propeller used on the American Los Angeles-class submarine as well as the German Type 212 submarine is called a skewback propeller. As in the scimitar blades used on some aircraft, the blade tips of a skewback propeller are swept back against the direction of rotation. In addition, the blades are tilted rearward along the ...
Feathering of these propellers is performed by the propeller control lever. [14] The constant-speed propeller is distinguished from the reciprocating engine constant-speed propeller by the control system. The turboprop system consists of 3 propeller governors, a governor, and overspeed governor, and a fuel-topping governor. [14]
The model was just 23-years-old when she walked into a plane's propeller in the dark, losing an eye, a hand and suffering brain damage. Because her tragic story made news headlines that night, the ...
Prop sychrophase acts much like a synchronizer to precisely match r.p.m., but the synchrophaser goes one step further. It not only matches r.p.m. but actually compares and adjusts the positions of the individual blades of the propellers in their arcs. There can be significant propeller noise and vibration reductions with a propeller synchrophaser.
