The invention discloses a DogLeg cooperation-based escort search and rescue calculation method. The method comprises the following steps of: 1, acquiring rescue machine information of a search and rescue aircraft; 2, acquiring aircraft information of the auxiliary aircraft, and setting a value of a DogLeg corner theta in a flight accompanying path of the auxiliary aircraft; thirdly, cooperative constraints between the search and rescue aircrafts and the auxiliary aircrafts are set; fourthly, the turning speed V1 of the auxiliary aircraft flying at a constant speed in the arc corner and the average speed V2 of the auxiliary aircraft flying along a straight line are set; 5, constructing a time cooperation relational expression f (t) = 0 between the search and rescue aircrafts and the auxiliary aircrafts; 6, constructing an air route cooperation relation formula f (x) = 0 between the search and rescue aircraft and the auxiliary aircraft; seventhly, the relative position relation between the search and rescue aircraft and the auxiliary aircraft is obtained. The invention aims to provide a DogLeg cooperation-based escort search and rescue calculation method and a DogLeg cooperation-based escort search and rescue calculation system which can timely and accurately plan flight routes of a helicopter and an auxiliary aircraft.

    本发明公开了一种基于DogLeg协同的护航搜救计算方法,第一步:获取搜救飞机的救援机信息;第二步:获取辅助飞行器的飞行器信息,设置辅助飞行器飞行的伴飞路径中DogLeg拐角θ的值;第三步:设置搜救飞机和辅助飞行器间的协同约束;第四步:设置辅助飞行器在弧线拐角内匀速飞行的拐弯速度V1,及辅助飞行器沿着直线飞行的平均速度V2;第五步:构建搜救飞机与辅助飞行器间的时间协同关系式f(t)=0;第六步:构建搜救飞机与辅助飞行器间的航路协同关系式f(x)=0;第七步:求得搜救飞机和辅助飞行器间的相对位置关系。本发明的目的是提供一种能够能够及时、准确规划直升机和辅助飞行器飞行路线的基于DogLeg协同的护航搜救计算方法及其系统。
