Rapid On Board Prototyping of Near-Optimal Spatial Trajectories for Pilot's Associate
Abstract
The paper deals with a concept, mathematical foundation and results of testing a prototype of onboard system providing an aid for pilot's control actions during more or less long-term maneuvers, such as takeoff/climbing, waypoint flight through the threat zones, surface-based and air target attack, descent and landing approach. The key issue of this system is to provide an algorithm allowing on-line prototyping of spatial trajectories for these maneuvers and visualisation of the reference trajectories to a pilot on 3-D flightpath display for further tracking. As an efficient tool for onboard optimization the, present paper considers different modifications of a direct method of calculus of variations, implemented to the tasks of flight dynamics first time by Prof. Taranenko in the early 60's. The paper contains a brief survey of the methods used so far by the other researches in the field, discloses main ideas of proposed approach, based on independent optimization of a trajectory and speed profile, shows how to assure a required convergence robustness. The paper is concluded with the reference to the semi-natural and flight test of the proposed system prototype, carried out in Russia in mid 90's in Zhukovskiy Air Force Engineering Academy and Gromov Flight-Test Institute.
