Abstract

This paper provides a brief overview of the activities undertaken by the Missile Facet of NATO STO AVT 316 (Vortex Interaction Effects Relevant to Military Air Vehicle Performance) since its first meeting in April 2018. Rather than setting out to provide definitive technical statements, a broader, more narrative approach is taken towards summarising some of the key developments that have occurred during the early stages of the facet’s existence. To date, work has focussed on investigating a blind test case (CFD_OTC1) based on a generic missile airframe at a supersonic flight condition. Attention is focussed on the predicted total rolling moment coefficient, the polarity of which determines the airframe’s local static roll stability. While the facet is still some way from demonstrably achieving verified CFD solutions at the flight condition of primary interest, there is now little doubt that the airframe will be predicted to be locally unstable in roll.
