Aero-thermo-servo-elastic Analysis and Optimization for High Speed Vehicles
Abstract
The objective of this proposal is to develop and demonstrate techniques that enableaccurate simulation and design optimization of high speed vehicles which include all therelevant disciplines in a high ?delity and tightly coupled manner. For high speed vehi-cles, the relevant disciplines include not only aerodynamics and structural dynamics, butalso thermal heating e -ects and the coupled interaction of all these disciplines with ightcontrol systems. Our strategy is based on coupling an existing unstructured mesh Reynolds-averaged Navier-Stokes (RANS) computational uid dynamics (CFD) solver that incorpo-rates a demonstrated time-dependent adjoint capability with an open source ?nite-elementstructural analysis solver. The structural analysis code is to be extended to include thermalanalysis, as well as multi-body dynamics of control surfaces for enabling analysis, forwardsensitivity, and adjoint sensitivity computations of realistic exible high-speed vehicles withmoving control surfaces. The goal of the project is to advance the state-of-the-art in compu-tational methods for high speed vehicles by developing and making available the necessarytechniques and software modules to accelerate the adoption of high-?delity aeroelastic, aero-thermo-elastic and aero-thermo-servoelastic simulations for high-speed vehicles.The proposed project directly targets advances in computational tools to enable predic-tive analyses, uncertainty quanti?cation and optimization for high speed vehicles such as theNavy s Hyper Velocity Projectile (HVP). The current project addresses critical technologiesfor high-speed vehicles that go well beyond the present state-of-the-art and are not on thecritical development path of the current DoD tool development e -ort. Although the currentproject does not address the e -ects of real gas behavior in the hypersonic regime, the resultswill be immediately applicable for lower speed regimes (e.g. supersonic) with the potentialto be extended to real gas hypersonic problems in future work. The emphasis in the cur-rent project is on the development and demonstration of the tightly coupled multidisciplinaryanalysis and adjoint capabilities for steady-state and time-dependent problems, in a modularfashion, that enables extension to further regimes and the inclusion of additional disciplinesin future work. At the same time, the basic technology of aero-servo-thermo-elastic analy-sis, uncertainty quanti?cation and optimization which is developed in this project will haveapplications to other classes of vehicles of interest to the Navy including ?xed and rotarywing aircraft. Our on-going association with the CREATE-AV project will provide a natu-ral pathway for rapid adoption by the Navy and other DoD entities for use of the softwaremodules developed in this project either as stand-alone tools or in conjunction with otherCREATE-AV software components.
