| 摘要： | This study presents a preliminary evaluation of the application of Thrust Vector Flight Control (TVFC) technology for improving windshear recovery of civil aircraft in a microburst encounter on final approach. A numerical trajectory optimization technique based on the method of multiple shooting is applied to achieve a microburst escape with minimal loss of altitude for a Boeing 727 type aircraft. Although the application of TVFC does result in a slight improvement in recovery altitude, there is also a price to pay in the sense that TVFC utilization significantly hampers the ability to gain specific energy during recovery. Maintaining an energy buffer during a microburst encounter is highly desirable to achieve robustness with respect to uncertainties in windshear size and strength. TVFC aided windshear recovery has been compared with an alternative approach to improve the windshear survivability capability, namely the application of lateral maneuvering. |
