赫克力斯宇航分公司研制了一种全尺寸、全石墨纤维的火箭发动机壳体,并成功地进行了试验。这是三叉戟-2先进研制计划的一个组成部分。这种直径为1.88米的壳体是用 AS4石墨纤维制成的。爆破试验表明,壳体强度、容积和重量诸特性均是优良的。初步试验说明,这种材料可能是三叉戟-2计划的一种有希望的待选材料。用这种纤维制 Hercules Aerospace has developed a full-size, all-graphite fiber rocket motor housing and successfully conducted the test. This is an integral part of Trident-2’s advanced research and development program. This 1.88 meter diameter shell is made of AS4 graphite fiber. Blasting tests show that the strength, volume and weight characteristics of the shell are excellent. Preliminary testing shows that this material may be a promising candidate for the Trident-2 program. Made of this fiber
