초록

항공기의 임무수행 시간을 연장하기 위해 도입된 공중급유를 수행하기 위해서는 두 항공기간의 랑데부 기동이 필수적으로 요구된다. 본 논문에서는 공중급유를 위해 가변 추적유도법칙을 이용한 랑데부 유도기법을 다룬다. 르야프노프 안정성 이론을 이용하여 가변 추적유도법칙 기반 랑데부 유도기법을 설계하였다. 제안한 유도기법은 두 항공기가 일정한 속력으로 비행하고 있을 때, 두 항공기 간의 헤딩각이 일치하도록 작동하여 랑데부 기동을 수행하도록 한다. 수치 시뮬레이션을 통해 제안한 랑데부 유도기법의 성능을 검증하였다.

A lot of studies to overcome the limitation of flight time have been studied, since the requirement of complicated mission achievement of aircraft including Unmanned Aerial Vehicles(UAVs) has been increased. The fuel limitation could bring about not enough flight time to accomplish missions. For this reason, the rendezvous maneuver is required to accomplish aerial refueling missions. The rendezvous guidance law based on variable pursuit guidance is designed using Lyapunov stability theory in this study. Numerical simulation is performed to demonstrate the performance of the proposed rendezvous guidance.
