missile is flying, the deflection of the rudder surface and the rotating missile body
form a control force to control the missile flight.
Previously, the main quality problems of the gas steering engine were poor
reliability, and there were some major faults such as valve core stopping, piston
jamming, and unqualified performance. Many times, the pilot fire test failed
because of the quality problems of the gas steering engine (Table 10.4). Only after
batch repairs, the pilot fire test passed.
In combination with production practice, the relevant personnel have carried out
many years of process technological research and ignition tests, and finally found
out the causes of the failure, and took effective measures to ensure the reliability
and performance requirements of the gas steering engine.
10.4.2 Redundancy Control
In gas steering engine, the fit clearance between valve sleeve and valve core, body
and piston is very small. In the work, the spool, piston, and bushing are in the
reciprocating linear motion state, especially with flowing gas. These characteristics
make the redundancy a great threat to the reliability and performance of gas steering
