Route Planning Technology In Vxworks

The integration of terrain following/terrain avoidance/threat avoidance is a new technique for the aircrafts to achieve low altitude penetration flight. And the trajectory programming technology is the important base of the design of control laws. It makes full use of the terrain shelter and the characteristic of the earth's curvatures to improve viability of aircrafts. The real-time operating system VxWorks can be used to develop embedded real-time system, so the trajectory programming technology is realized in it. This paper mainly studies the algorithm of the terrain following/terrain avoidance/threat avoidance trajectory programming technology and its realization in VxWorks.The main tasks of this dissertation are summarized as follows:1) The trajectory programming technology. This paper presents a wider research field -RISK ANALYSIS.Through the study of the effects that threat factors and error factors impact on the flight risk and adjusting performance rules, the horizontal safe corridor, threat avoidance, vertical altitude real-time modification and the fastest trajectory programming are progressed.2) The realization of trajectory programming technology in VxWorks. The tasks are sorted and scheduled according to the astringency and classifiability of the algorithm.
