A study on the effect of altitude-compensation and the possibility of throttling is performed by designing an E-D nozzle that is a type of altitude-compensation nozzles. In order to examine the effect of the altitude-compensation, a CFD analysis is conducted by using three kinds (sea level, altitude at 10 km and 16 km) of the atmosphere condition while maintaining the chamber pressure. Results show that the effective nozzle exit area is also gradually increased when the altitude get increased. Understanding the possibility of throttling, a CFD analysis is conducted by moving the location of the pintle. Just as same as a general pintle thruster, the chamber pressure and thrust are increased when the nozzle throat area get decreased.

철강재의 산소절단은 연료가스의 연소열 및 철의 산화 반응열을 이용하여 강재를 절단하는 방법이다. 연료가스의 연소열을 이용하여 강재를 가열 및 용융시키고, 여기에 고순도의 산소를 취입하면 강재의 용융물질 중 철의 급격한 산화반응이 발생된다. (중략)
