Panel-Frame Interaction Studies for High-Speed Vehicles
Abstract
Fielding high speed vehicles has long been a goal of the U.S. Air Force to increase its operational envelope. Given the high speed flow, parts of such vehicles, referred to as panels here, will be subjected to large aerodynamic pressure and heating. This will result in large deformations and strong nonlinearities in the structural response with feedback to the aerodynamics inducing a strong fluid-thermal-structural interaction (FTSI). However, other parts of the vehicles, referred to as frame here, will experience smaller loading and lower temperatures inducing reduced structural responses and possibly decreased FTSI coupling. Panel-frame assemblies form a general framework to understand the interactions of different parts of the vehicle and to upscale panel only knowledge-methods to multi-component vehicles. Designing high speed vehicles will require physical understanding and efficient prediction strategies of the response of panels and frame but also of their interactions. These include frame deformations effects on panel buckling, panel snap-through induced by frame dynamics, nonlinear energy transfer between panel and frame, etc.
