1. Non-rotating outer ring (blue). 2. Turning inner ring (silver). 3. Ball joint. 4. Control (pitch) preventing turning of outer ring. 5. Control (roll). 6. Linkages (silver) to the rotor blade. In aeronautics, a swashplate is a mechanical device that translates input via the helicopter flight controls into motion of the main rotor blades.
A line-replaceable unit (LRU [1]), lower line-replaceable unit (LLRU), [citation needed] line-replaceable component (LRC), or line-replaceable item (LRI) [2] is a modular component of an airplane, [3] ship or spacecraft [4] (or any other manufactured device) that is designed to be replaced quickly at an operating location (1st line). The ...
Contra-rotating, also referred to as coaxial contra-rotating, is a technique whereby parts of a mechanism rotate in opposite directions about a common axis, usually to minimise the effect of torque. Examples include some aircraft propellers , resulting in the maximum power of a single piston or turboprop engine to drive two propellers in ...
A PTO at the rear end of a farm tractor A PTO (in the box at the bottom) in the center of the three-point hitch of a tractor. A power take-off or power takeoff (PTO) is one of several methods for taking power from a power source, such as a running engine, and transmitting it to an application such as an attached implement or separate machine.
In 1980, the American Helicopter Society International offered a prize of US$10,000 for the first human-powered helicopter flight (60-second duration, a height of 3 meters, and staying within an area of 10 x 10 m) and soon increased prize money to US$25,000. In 2010, Sikorsky Aircraft pledged to increase the prize sponsorship to US$250,000.
The helicopter rotor is powered by the engine, through the transmission, to the rotating mast. The mast is a cylindrical metal shaft that extends upward from—and is driven by—the transmission. At the top of the mast is the attachment point (colloquially called a Jesus nut) for the rotor blades called the hub.
The pitch of the tail rotor blades is adjustable by the pilot via the anti-torque pedals, which also provide directional control by allowing the pilot to rotate the helicopter around its vertical axis. Its drive system consists of a shaft powered from the main transmission and a gearbox mounted at the end of the tail boom.
