A method of evaluating reliability of large-scale rocket engines during a research and development program prior to missile flight tests is presented. Reliability estimates are obtained even though the configuration of the engine is undergoing change and the objectives of test firings vary. Each ...
The Sixth Academy of the China Aerospace Science and Technology Corporation (CASC) announced on Tuesday that the time for the test – accounting for the time the engine was placed on the test stand to ignition – has been reduced from three days. The announcement was made ...

My father worked there in the early 70s, when they went bankrupt due to engine development costs. MC01 Jun 2, 2019 at 11:50 am The problem is not that RR will become insolvent (if I remember correctly only individuals can go bankrupt in England). The company is doing fine and is ...
Through the status analysis of software development modes of ground testing and control system for the domestic large-scale rocket engines,the Rational Unified Process"4+1"view method is proposed.The modeling of measurement and control system software was carried out in combination with object-oriented...
摘要: Large, liquid, rocket‐engine‐component tests demonstrated the effectiveness of an acoustic filter in decoupling propellant‐feed‐system oscillations from the combustion process in a gas‐generator system. Test data are included. Reference is made to several other acoustic‐filter applications....
