The Measurement Technique of Burning Rate in Solid Proplellant at High Pressure
고체추진제의 고압 연소속도 측정기법
Abstract
The burning characteristics of HTPB/AP solid propellants were measured by closed bomb of internal volume of 200 cc and 700 cc up to 30,000 psia. The burning rates of closed bomb method showed good agreement with those of strand burner method between 1,000 psia and 5,000 psia, and the sharp increment of pressure exponent(n) around 6,000 psia as a result of testing in accordance with loading densities. The burning rate measured in 200 cc and 700 cc of internal volume of closed bomb agreed well without the relation of internal volume size.
본 연구에서는 내부용적이 200 cc와 700 cc인 closed bomb을 이용하여 30,000 psi까지 HTPB/AP 추진제의 연소 특성을 고찰하였다. 장전 밀도에 따라 closed bomb법에 의해 측정한 결과 연소속도는
