In aeronautics, a swashplate is a mechanical device that translates input via the helicopter flight controls into motion of the main rotor blades. Because the main rotor blades are spinning, the swashplate is used to transmit three of the pilot's commands from the non-rotating fuselage to the rotating rotor hub and mainblades.
By varying the angle of the swashplate, the pistons' stroke (and, therefore, the compressor's cooling capacity) can be dynamically adjusted. A helicopter swashplate is a pair of plates, one rotating and one fixed, that are centered on the main rotor shaft. The rotating plate is linked to the rotor head, and the fixed plate is linked to the ...
The data portion is organized into 512 range bins per scan angle value. Each (three-bit) range bin contains a color value to indicate the intensity at that position. Settings for the ARINC 708 system is typically controlled using an ARINC 429 interface.
The position of the lenses A and B are known, and the angle of the lenses α and/or β is set by the operator so that both are aimed at the target. Because the distance between A and B on a coincidence rangefinder is typically fixed, once the angle is set correctly the operator need only read the range from the scale.
For instance, Kaman Aircraft helicopters do not use a traditional swashplate and instead operate servo flaps on the rotor blades to adjust the angle of attack of the blades. Unfortunately, the link for "servo flaps" leads to an article about fixed -wing flaps; I can't find anything there about flaps on rotor blades.
In fax systems, skew is the angular deviation of the received frame from rectangularity caused by asynchronism between the scanner and the recorder. This is the same as the angle between the scanning line, or recording line, and the perpendicular to the paper path. [1] Skew is expressed numerically as the tangent [broken anchor] of the ...
The Cylindrical Energy Module (CEM) is a sine-wave swashplate engine that can also be used as a standalone pump, powered by an external source. The rotating swashplate rotor assembly is moved back and forth with the help of piston drive pins, which follow a stationary sinusoidal cam track that encircles the rotor assembly. [citation needed]
A depression position finder measured the range to a distant target (such as a ship) by solving a right triangle in which the short side was the height of the instrument above mean low water; one angle was the constant right angle between the short side and the plane of the ocean, and the second angle was the depression angle from the horizontal of the instrument as it sighted down from a fire ...
