我国进行了重型火箭25吨级膨胀循环氢氧发动机首台推力室挤压试验,试验取得圆满成功
Combustion chamber of third stage engine for CZ-9 (
11) was tested. The engine is 25 tonne force thrust, expander cycle. Two tests were done at 60% and 100% thrust. The tests did not involve the expansion of LH and LO, only the combustion chamber. LH and LO were fed by compression. It is ready for full system test.
There is a statement "该型发动机是目前世界推力最大的膨胀循环氢氧上面级发动机"/This engine has the highest thrust among expander cycle. I know why it is claimed to be so. Just curious if anyone is going to reject that on what definition.
