舰载飞机弹射起飞参数的优化研究

为了充分利用各种有利因素提高舰载飞机的弹射起飞性能，采用共轭方向法对舰载飞机弹射起飞参数进行了优化研究，优化计算结果表明，单独依靠前起落架的突伸会导致过大的前起落架载荷，只有把前起落架的突伸和升降舵的操纵相配合，才可以获得满意的弹射起飞航迹。

THE STUDY OF THE PARAMETER OPTIMIZATION OF CATAPULT TAKE-OFF FOR A CAKRIER-BA8ED AIKPLANE

In order to make full use of all the advantages to improve the performance ofthe catapult take-off for carrier-based airplanes,this paper studies the parameter optimiza-tion of catapult take-off for a carrier-based airplane by the conjugation direction method(Powell).The results of optimization computation show that,supposing we only use the fast-extension of the nose gear,it will lead to the over load of the nose gear.The satisfactorycatapult take-off path can be obtained only by matching the nose gear fast-extension with the control of the elevator.
