KRASH Analysis Correlation. Transport Airplane Controlled Impact Demonstration Test.

Abstract

The analyses results of a transport airplane Controlled Impact Demonstration (CID) test using programs KRASH are described. Pre-CID analyses, presented in FAA technical report DOT/FAA/CT-85/9, are provided in summary form. The KRASH post CID correlation consists of modeling two sequences; a symmetrical impact of the fuselage with the ground (after engine-loss at initial air-to-ground impact) and the unsymmetrical air-to-ground including initial engine ground contact and subsequent fuselage impact with the ground. The analyses and test results are compared with regard to floor acceleration responses, fuselage shear and bending moment distribution, wing and engine acceleration responses, wing bending moment distribution, structural failures, fuselage underside crush, and sequence of events. Keywords: Aircraft fires; Aviation safety; Crash landings; Crash resistance; Aviation accidents.
