ABSTRACT:
Nose landing gear jump strut assembly includes an outer main housing cylinder containing a jump cylinder which is normally retained in a retracted position but is extendable on command during the take-off ground roll of the aircraft to accelerate the outer main housing cylinder upward thus to rotate the nose of the aircraft upward and thereby increase the angle of attack of the aircraft. Within the jump cylinder is the main strut piston which is free to move relative to the jump cylinder except during extension of the jump cylinder, the main strut piston is hydraulically locked for movement with the jump cylinder. After the jump cylinder has been fully extended, and the aircraft starts to become airborne, the main strut piston will move to its fully extended position. Then the jump cylinder is retracted, while still leaving the main strut piston fully extended.
