验证土星S—IC箱体结构强度的方法是一种无损液压试验法。虽说这个方法可用,但有时也要做破坏性液压试验。而且只有做这种试验,才能取得有用的数据。由于飞行设计的重量考虑,取安全系数很小,一般取屈服/设计载荷之此为1.1到1.0,材料有一点制造上或碰伤缺陷都会导至彻底毀坏。虽然大多数缺陷在工厂检验中已能排除,但只有满载验证试验才能取得飞行的尤其是载人飞行的历要求的安全度。目前使用的大箱体的锥壁厚设计不能用以往的方法试验.因为以往的液压试验条件同
Saturn S-IC box to verify the structural strength of the method is a non-destructive hydraulic test. Although this method is available, sometimes destructive hydraulic tests are also required. And only by doing this kind of experiment can we get useful data. Due to the weight of the flight design, taking the safety factor is very small, usually take the yield / design load of 1.1 to 1.0, a little material manufacturing or bump defects will lead to complete destruction. Although most of the deficiencies have been ruled out in factory inspections, only full load validation tests can achieve the required safety of flight, especially manned flights. The cone wall thickness of the large box currently used can not be tested by the conventional method because the conventional hydraulic test conditions are the same
