LANDING GEAR DEVELOPMENT

Abstract

A screening test program was conducted on five promising materials for use in the X-20 landing gear energy-absorbing system. The materials tested were Inconel, 'A' Nickel, Hastelloy X, 19-9DL, and 304 ELC. A total of two hundred and two (202) two-inch gage length tensile specimens were tested under various combinations of temperatures and strain rates to obtain stress-strain curves for comparing the materials. Inconel was concluded to be the over-all best energy strap material for the X-20 landing gear application. The energy strap development program was continued with the testing of proposed full-scale main gear and nose gear energy strap configurations under simulated X-20 landing environments.
