Outline of Final Research Achievements

The final purpose of this research is to develop a new algorithm to calculate the optimal trajectories of aircraft in the terminal area. In order to generate the algorithm, time-space coordinate is introduced and the optimal control problem is transformed to a problem to draw optimal line in a mathematical space. In the time-space coordinate, time is treated as one of state variables. In a case when two aircraft have risk of conflict, there are two ways for pilots to avoid the collision. One is to change the course of aircraft to provide separation in space and the other is to change the speed of aircraft to provide separation in time. It is sometimes difficult to choose one of two ways. In such case, time-space coordinate provides benefit to reduce computational time. Numerical results using actual data show the benefit and the applications of time-space coordinate.
