ABSTRACT:
A wheel-through ski for the landing gear of an aircraft is disclosed. The ski has an airfoil shape, and the ski and its attachments are aerodynamically clean. The ski is provided with a three sided recess that permits the mounting of the ski on the aircraft without lifting the landing gear off the ground. The members of the articulated attachment between the ski and the aircraft are joined by a removable pin and are fixedly attached to the ski and landing gear. The ski is of aircraft construction. It has a thin skin, air frame-like internal structures, foam material internal cores that provide stiffness to the ski and wear strips on the bottom of the ski.
