“…It was estimated that it was because the line pressure oscillation level was not so large (about 20 % of the normal pressure). 5) As a result, the surge pressure due to the water-hammer phenomena can be accepted in the propulsion sub-system design if the propulsion system is kept compact with short feed line, the required pulse patterns are not so severe or the duration of the pulse operation is short. In most cases, the surge pressure level or the thermal tolerance of thrusters are evaluated after the system design is almost completed.…”

This paper describes the evaluation method of the new Japanese thrusters design, balancing and verification of interface compatibility with the HTV system and operation design. Thruster performance directly affects the performance of the space craft. Therefore, the thruster replacement from the imported thrusters to the new Japanese thrusters required the evaluation from the view point of high-order system level. It is important to select the appropriate elements, verify their relationships, and create a feedback mechanism which allows modification of each element. This method will facilitate the overall systems design for future inter-orbit transfer vehicles.
