MH-60R - Systems - Miscellaneous Flashcards
(6 cards)
Briefly describe the main landing gear
Each single-wheel main gear is mounted on a drag strut that trails aft from a pivot point mounted on the fuselage. A separated air/oil type shock strut is mounted on the fuselage and to the aft end of the drag strut. A landing gear Weight-on-Wheels (WOW) switch is installed on the left main mount and controls operation of selected systems.
What is the purpose of the long stroke of the landing gear?
It is designed to dissipate high sink rate landing energy without exceeding the ship deck strength limits.
Briefly describe the tail landing gear
The tail landing gear (Figure 2-54) is of a cantilever design, with an integral shock strut capable of swiveling 360°. The two tail gear wheels are mounted on a splined axle incorporated in the shimmy damper. The shimmy damper causes both of the tail gear wheels to rotate at the same rate, preventing aircraft tail oscillations during taxi, takeoff, and running landings. For helicopter guidance for traversing on the flight deck, a RAST tail probe and probe actuator are mounted on the tail gear.
How does the tail wheel lock pin work?
The tail wheel can be locked in the trail position by a TAIL WHL switch, located on the lower console, labeled LOCK/UNLOCK. An electrical actuator positions the locking pin in the fork assembly.
What makes up the brake system?
The wheel brake system consists of four master cylinder/reservoirs, two slave valves, a parking brake valve, and two wheel brake assemblies.
To what are the brake master cylinders connected?
A master cylinder is connected to each tail rotor pedal.
