Abstract
A nose landing gear assembly for an airplane which can be launched with catapult assistance. The landing gear assembly includes a nose strut, upper drag link, lower drag link, launch bar and launch bar actuator. When the nose shut is in the extended position, the upper drag link, lower drag link and launch bar form a direct load path between the catapult shuttle and the airplane thereby avoiding subjecting the nose strut to loads reacted from the shuttle. The nose strut, launch bar, launch bar actuator and airplane fuselage form a first four bar linkage. Furthermore, the nose strut, upper drag link, lower drag link and airplane fuselage form a second four bar linkage such that during retraction of the nose strut, the launch bar, launch bar linkage, upper drag link and lower drag link are caused to move up and into the airplane wheel well.
