Analysis of the Flight Dynamic During Flying Wing UAV Carrier Landing
摘要
Abstract
Flying wing UAV has distinct aerodynamic characteristic.It's of great significance to research the flight dynam?ic character for the design of control law during the carrier-landing of flying wing UAV.A six-degree-of-freedom flight dynamic model of flying wing UAV carrier landing was presented.Based on the analysis of the flight stability of the UAV gliding,the range of approaching velocity achieving flight quality of first-class level was calculated,according to the re?quirement of the flight quality to the flight stability.Through the trim calculation and small perturbation linearization,the linear model of UAV gliding motion was obtained. The longitudinal and lateral-directional modal properties were ana?lyzed. Results showed that during the flying wing UAV gliding, the longitudinal long-periodic and short-periodic mode and the lateral-directional roll and spiral mode became convergent slowly,but the dutch roll mode was divergent.关键词
