초음속 유동장치의 설계 및 성능시험 = The Design and Performance Evaluation of a Supersonic Cold Flow System

다국어 초록 (Multilingual Abstract)

Theoretical analysis, design and evaluation of a supersonic cold-flow system were conducted. It is designed to study of jet-vane for Thust Vector Control system, but a design process is similar general that of supersonic cold-flow system. The nozzle for this system was designed same exit Mach number as that of real rocket motor, because the jet boundary of designed nozzle approximated to real jet boundary very closely. The working gas is air exit Mach No. is 2.88, and nozzle chamber volume is 1.5ℓ.
From the result, proper test time is about 0.3 seconds, low pressure chamber pressure and the measured axial thrust are appeared to 83% and 83.7% of the theoretical data respectively. It is due to pressure loss in sudden divergent-convergent section.
