面向在线变形的跨域变构型飞行器气动设计方法
Aerodynamic design methods for cross-domain morphing aircraft oriented to online deformation
摘要
Abstract
Morphing aircraft,which adapt their aerodynamic shape online to meet mission demands,are a prominent research topic for maintaining high performance across wide flight envelopes.To address the challenges of integrated coordination between online/offline design variables and multi-profile heterogeneous constraints in the aerodynamic de-sign of morphing aircraft,we develop a multi-mission aerodynamic design method for cross-domain aircraft.The pro-posed method parameterizes the aerodynamic shape with both online and offline variables and constructs an inner-outer dual-layer coupled optimization framework aimed at achieving a globally optimal offline shape while meeting the optimal online configurations for each flight profile.The method was applied to a variable-sweep cross-domain aircraft,and shape optimization is carried out for take-off/landing(max lift coefficient)and high-speed flight(max lift-to-drag ra-tio with center of pressure constraints).Depending on the objective weights,the optimized lift coefficient at Ma=0.4 in-creased by 55.03%and 56.85%,while lift-to-drag ratios at Ma=6.0 and Ma=10.0 increased by 1.16%,1.69%and 0.94%,1.68%,respectively.Crucially,the high-speed center of pressure variation was successfully controlled within the 2%design constraint in all cases.These results verify the effectiveness of the proposed optimization framework.关键词
