Stress Analysis Of An Aerodynamically Loaded Structure Under Supersonic Conditions

Abstract

This paper presents a stress analysis carried out in order to understand the effect of engine intake aerodynamic loads on the F-111 FS496 former and surrounding intake structure. In the cases investigated, the air pressure distributions were known, so the air pressure was applied directly to the intake nacelle wall. A sensitivity study was subsequently carried out to compare a real pressure distribution and different functions representing the pressure distribution. It was concluded that the results were not greatly affected by the different functions
