摘要
通过对某型固定翼舰载机(以下简称舰载机)纵向动力学运动特性的分析计算,绘制了其推力/阻力与速度的关系特性曲线和进场轨迹稳定性的飞行品质分析判定曲线,阐明了舰载机进场动力补偿区(以下简称反区)操纵特性的成因;通过飞机非线性全量模型仿真计算了舰载机正区操纵和反区操纵的完整响应过程,指出了其中的差异,进一步论证了这种分析方法的科学性;最后对现行的保持速度恒定和迎角恒定的两种油门控制策略进行了仿真研究,指出了两种油门控制策略的优缺点。
This paper analyzes the characteristics of a carrier aircraft longitudinal dynamics movement,plots its characteristic curve of thrust/drag and speed and the approach trajectory stability curve, and describes the causes for power compensation area （backside） handling characteristics of carrier aircraft approach. Then a nonlinear model simulated the whole aircraft response process at the front side, pointed its difference and further demonstrated the scientific nature of this analysis method. Finally, two popular throttle control strategies-maintaining a constant speed or constant angle of attack, and point out the ad- vantages and disadvantages of the two throttle control strategies.
