10.1.3.2 Experimental Results and Analysis of Thrust
(1) Thrust Experiment Without Orifice
The high-pressure gas source is directly ejected through the relief valve and nozzle,
and the thrust fluctuates greatly. The change of air pressure or load flow in the relief
valve will make the displacement of the relief valve core change dynamically,
which will cause the output pressure of the relief valve to change dynamically and
