6 FAQs about [Servo valve boost accumulator]
What is a boost servo?
Boost servos make it easier for the pilot to move the pedals and collective stick and prevent SAS feedback into the flight controls in the yaw and pitch channels. 2. Stall force (power piston). Force is approximately 785 pounds at 3000 psi. (c) Mixing Unit. 1. Description.
What is a yaw boost servo?
(2) Yaw boost servo. This servo reduces flight control friction, and prevents feedback from the Yaw SAS actuator in the cockpit controls. (3) Tail rotor cables (2 each). Two cables connect to the yaw controls (located aft of the mixer) to an aft quadrant (located just forward of the tail gearbox). (4) Tail rotor quadrant. (a) Description.
How do servos work?
The servos control the non­rotating swashplate, allowing the pilot to control the M/R system. 3. Two pressure switches, one for each stage, are located on top of each servo assembly. These switches will illuminate the first or second stage primary servo pressure caution lights if there is a loss of pressure.
How does a 2 servo system work?
The #2 hydraulic system supplies hydraulic pressure through the #2 transfer module to the second stage of all primary servos and to all pilot assist servos. b. Components. (1) Pump module. This module is the same as the #I pump module and is located just inboard of the #2 generator on the right­hand accessory module.
Where is the boost servo located?
These servos are located in the hydraulic compartment forward of the mixing unit. The collective boost servo is on the right­hand side, and the yaw boost servo is on the far left­hand side of the pilot assist manifold.
What is the purpose of a servo?
Purpose. Servos assist the pilot to overcome friction created by flight controls. They eliminate SAS feedback and friction to the flight controls caused by the engine controls and also provides a means for FPS inputs to go through the flight controls.
