Integration of Wake Vortex Eects in Simulationsof UAVs in Close Formation Flight

摘要

This paper addresses the development of multiple UAV deployment simulation models so as to includerepresentative aerodynamic cross-coupling eects. Applications may include simulations of autonomousaerial refuelling and various surveillance and search & rescue scenarios. A novel wake vortex modelwas developed and successfully integrated within a Matlab/Simulink simulation environment. The wakevortex model meets the following requirements: (I) it is suciently representative to support studies ofaerodynamic interaction between multiple air vehicles; (ii) it is straightforward enough to be used withinreal time or near real time air-to-air simulations. The emphasis of this paper is put on the integrationprocess, and simulation results of a two vehicles formation flight are presented.The simulation models will be used to support in-depth investigations on the likely impact of dynamicair vehicle interactive coupling on autonomous control requirements for multiple vehicle deployment.The wake vortex model has been integrated within the Cobham Synthetic Environment for air-to-airrefuelling studies.
