Diffraction Phase Loading of Structures.

Abstract

The response of the KC-135 and 747 aircraft to a nuclear gust were calculated using the VIBRA-4 code. Runs were made with and without diffraction phase loading to determine the effect on the aircraft response. The differences in the calculated ratios were small for the KC-135 model, but large differences were found with the 747 model. Clearly the diffraction phase can exert a large influence on the nuclear gust imposed loads, but it was not possible to predict this effect in advance. (Author)
