Impact pressure distribution measurements in free and impacting cold nitrogen thruster jets operated in atmospheric and low-pressure environments,and N2-H2 arc-heated jets generated in low-pressure environment have been made by using a self-designed impact pressure probe.The integrated sums of the impact pressure have been compared with the thrust force measured by the impulse method.Results show that the measured impact pressure of the cold nitrogen free/impacted jets operated at atmospheric pressure exhib...
