过去本刊已多次报导,所谓小体积冲压发动机就是火箭药柱装在冲压燃烧室中的整体式火箭——冲压发动机。由灵——特姆科——沃特航宇公司为美国海军航空系统司令部研制的这种发动机,已在马夸特公司的范奈斯高超音速风洞中第一次完成了工作转换试验。工作转换时,四个进气口打开,火箭喷管被抛掉。固体药柱大约在5秒内耗尽,接着冲压发动机工作,持续了差不多10秒,以前进行的冲压发动 In the past, we have reported many times that the so-called small-volume ramjet engine is a one-piece rocket-ramjet engine equipped with rocket lances in a stamped combustion chamber. The engine, developed by Spirit-Temuco-Waters Aerospace for the U.S. Naval Aerospace Systems Command, has completed its work-transfer test for the first time in the Marquardt’s Beaune’s hypersonic wind tunnel . Work conversion, the four air intakes open, rocket launchers were thrown away. The solid pellets were depleted in about 5 seconds, followed by ramming the engine for about 10 seconds, the previous ram launch
