ABSTRACT OF THE DISCLOSURE A rapidly extendible, rough-field attenuating shock- absorbing strut, particularly adapted for use with an aircraft having a tricycle landing gear, The strut is used during takeoff and is adapted for rapid extension to provide angular or upward momentum to the aircraft and thus facilitate takeoff. The strut comprises an outer cylinder which is secured to the aircraft and an inner cylinder adapted for longitudinal reciprocation within the outer cylinder. The inner cylinder has a wheel mounted thereon at the end opposite that of the outer cylinder, A piston is secured for longitudinal reciprocation within both the outer and inner cylinders, The piston has a piston head adapted for reciprocation within the outer cylinder. Means are provided for applying fluid pressure to the piston head to cause is to move longitudinally toward the inner cylinder and means are provided in association with the piston and inner cylinder for moving the inner cylinder longitudinally and away from the aircraft and outer cylinder when said piston moves toward the inner cylinder, This causes rapid extension of the inner cylinder to provide angular or upward momentum to the aircraft, Also means are provided to allow the inner cylinder to reciprocate within the outer cylinder by altering the flow and/or amount of the fluids within the strut for shock attenuation over rough surfaces. *********
