Abstract
An active oleo system for an aircraft semi-levered landing gear system disclosed herein includes a main strut, an auxiliary strut, bogie beam, and a pressure boost mechanism. During a takeoff roll phase, the pressure boost mechanism may increase the pressure in the main strut, forcing the main strut piston to the fully extended length. Thru the action of main strut, auxiliary strut, and bogie beam this may increase the height of the aircraft above ground, providing for a larger achievable rotation angle of the aircraft.
