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 ...
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.
Tilts main rotor disk left and right through the swashplate: Induces roll in direction moved To create movement to sides To move sideways Collective Collective angle of attack for the rotor main blades via the swashplate: Increase/decrease pitch angle of all main rotor blades equally, causing the aircraft to ascend/descend Increase/decrease torque.
Phase lag is not to be confused with advance angle, which refers to the mechanically fixed angle between the pitch link attachments at the blade and the swashplate. Advance angle is fixed and cannot vary.
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]
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.
Side-scan sonar and magnetometric sensors for proximity detection of submarines and decoys have been added. Torpedo agility and maneuverability are also improved. The Type 12 has approximately 38% parts commonality with the Type 97; plans are in effect to use parts from decommissioned Type 97 units to construct new Type 12 units.
A swashplate at one end is connected to the pistons. As the pistons rotate, the angle of the plate causes them to move in and out of their cylinders. A rotary valve at the opposite end from the swashplate alternately connects each cylinder to the fluid supply and delivery lines. By changing the angle of the swashplate, the stroke of the pistons ...
