DEVELOPMENT OF AIRCRAFT SHOCK ABSORBERS USING FRICTION AS THE ENERGY DISSIPATOR

Abstract

The purpose of this study is to evolve and evaluate a number of preliminary aircraft landing gear designs or concepts utilizing shock absorbers based on friction energy absorption methods adaptable to high temperature use (1000 F and up). Initial studies developed as many concepts as possible, without attempting to size components, but merely to portray an idea. Four concepts were selected from the initial study and preliminary designs of the selected concepts were prepared based on landing and take-off characteristics of the USAF F-100 aircraft. Scale model drawings were then developed based on the full scale landing gear designs to experimentally evaluate the proposed designs. Data indicates that friction methods have extremely high energy absorption capacities, that the coefficient of friction is relatively insensitive to temperature variations and that a centrifugally controlled friction device has sufficient advantages to warrant further research effort.
