Measurement of suspension loads and determination of suspension reliability for a store in the F-111 weapons bay

PDF Version Also Available for Download.

Description

The dynamic store suspension environment in an open bay of the F-111 aircraft is under investigation. This experimental study was prompted by the uncertainties relative to the loads on the store suspension system which result from the severe aerodynamic environment in the open bay. Because of the complex flow field which exists, the loads on the swaybraces, vertical chocks, horizontal chocks, and lugs are not amenable to accurate analytical predictions. In an effort to verify that a store is capable of withstanding the loads experienced during carriage to the performance limits of the aircraft, an experimental buildup program was undertaken ... continued below

Description

The dynamic store suspension environment in an open bay of the F-111 aircraft is under investigation. This experimental study was prompted by the uncertainties relative to the loads on the store suspension system which result from the severe aerodynamic environment in the open bay. Because of the complex flow field which exists, the loads on the swaybraces, vertical chocks, horizontal chocks, and lugs are not amenable to accurate analytical predictions. In an effort to verify that a store is capable of withstanding the loads experienced during carriage to the performance limits of the aircraft, an experimental buildup program was undertaken and is currently in progress. This paper discusses the design of the unit which is being used to measure the random loads on the suspension system during open-door carriage and the methods used to establish the reliability of the store suspension system. A numerical example shows that the suspension system of the store under consideration is highly reliable.
