Evaluation of the capabilities of CFD to predict store trajectories from attack aircraft

Abstract

This paper explores the advantages of using computational fluid dynamics (CFD) to predict store trajectories. The focus will be on comparing CFD based store separation predictions with experimental data derived from wind tunnel and flight tests. Of particular interest are the abilities of new engineers to use various CFD packages to accurately predict store captive loads and separation forces, moments and trajectories in support of real stores clearance processes. The first phase made use of existing CF-18 Aircraft/MK-83 trajectory data from on-going flight-tests by the Canadian Airforce. NOMENCLATURE
