저진공상태에서 노즐 팽창비와 비열비에 따른 마이크로 노즐의 특성 연구
Characteristic Study of Micro-Nozzles according to the Ratios of Nozzle Expansion and Specific heats in low vacuum condition
- 발행 : 2006.08.23
초록
We conducted the experiment to analyze characteristics of micro-nozzle using different cold gas under two different nozzle expansion ratios in low vacuum condition. We measured thrust and chamber pressure and mass flow rate under low vacuum condition, and then compared them with those in ambient pressure.
