摘要
本文研究了舰载飞机的前起落架突伸对弹射起飞航迹的影响．在动力学模型中，把起落架看作是由油气减震器和充气轮胎组成的减震装置．在弹身器末端，前起落架在压缩空气的推动下开始突伸，以增加飞机的离舰迎角。本文计算了两种突伸方式，并比较了它们的结果，这两种方式均能减小离地后的航迹下沉量，并能很好改善弹射起飞性能．
This paper studies the influence of the nose gear fast-extension on the catapult trajectory for the carrier-based airplane. In the dynamic model,the landing gear is considered as a damping device, which consists of an oil-air damper and an air tire. At the end of the catapult stroke, the nose gear begins fast-extending by compressed air to increase the attack angle of the airplane. In this paper, two kinds of fast-extension are calculated and compared with each other. Both kinds can reduce the height loss after the airplanetaking off from the carrier. It can improve the catapult take off performance considerably.
