在直径为100英尺、压强为20乇(0.39磅/英寸~2)的真空容器里,完成了三次半人马座标准整流罩(以下简称标准罩——译者注)的高空抛掷试验。该真空容器是刘易斯研究中心普卢姆·布鲁克站空间动力研究设备的一部分。这些抛掷试验是在太阳神和海盗任务的准备阶段、在新的标准罩系统上完成的一系列鉴定飞行试验中的一部分。前两次抛掷试验模拟了爬高状态气动加热的温度变化,第三次试验是在一定高度压力和常温条件下进行的,常温试验的目的是为了提供基本数据。利用这些数据可分别考虑影响抛掷特性的力学的和温度的因素。上述的三次试验都是成功的,获得了温度、应力、结构挠度的数据。这些数据检验了标准罩承包者(洛克希德导弹空间公司)所预示的标准罩飞行环境条件和抛掷特性。同时,也获得了标准罩与有效载荷之间在抛掷之前和抛掷期间的临界间隙损失的数据。爆炸索分离系统在最高飞行温度状态下,证明是有效的。
Three throws of Centaur fairing were completed in a vacuum vessel with a diameter of 100 feet and a pressure of 20 torr (0.39 lb / in 2). The vacuum vessel is part of the Space Dynamics Research Facility at the PLUMB Research Station at Lewis Research Center. These toss tests are part of a series of qualification flight tests performed on a new standard hood system during the preparation phase of the Apollo and Pirates missions. The first two throwing tests simulate the temperature change of the high-temperature aerodynamic heating. The third test is carried out under a certain degree of pressure and room temperature. The purpose of the room temperature test is to provide basic data. These data are used to take into account the mechanical and temperature factors that affect the casting behavior, respectively. The above three tests were successful and obtained the data of temperature, stress and structural deflection. These data verified the standard hood flight environmental conditions and throwing characteristics as forecasted by a standard hood contractor (Lockheed Martin Missile Space Company). At the same time, the data of the critical clearance loss between the standard cowl and the payload before throwing and during casting are also obtained. Explosive cable separation system at the highest flight temperature state, proved to be effective.
