高速弹射试验机操稳性能的计算与试飞

本文介绍了为研究高速弹射试验机的操稳性能和在弹射力扰动下飞机的动态响应,把弹射力以瞬态脉冲载荷的形式作用于飞机时所建立的数学模型和采用的计算方法.把计算结果与试飞结果和原型机试飞结果作了比较,计算结果与试飞结果的一致性是令人满意的。这为高速弹射试验机的安全飞行和指导飞行员实施弹射试验提供了可靠的依据。

CALCULATION AND FLIGHT TEST ABOUT CONTROL AND STABILITY OF A HIGH-SPEED EJECTION TEST AIRCRAFT

This paper presents the mathmatic modeles and calculating method of the dynamic response under the disturbance of the launch force, which is acted on the aircraft in the form of instantaneous pulse load, in order to study the control and stability of high-speed ejection test aircraft. The computed results is compared with the flight test results of the test aircraft and the prototype aircraft. The identity between the computed results and the flight test results is satisfactory. That provides the reliable basis for the safety flight, ejection test, as well as guiding pilot to make ejection test.
