[IBRGAC] A Lumped-Parameter Interior Ballistic Computer Code Using The Ttcp Model.pdf
1.18MB
IBRGA is a simple FORTRAN code for making computer simulations of the interior ballistic performance of guns. It can be run on computers as small as an IBM PC. It is based on the lumped-parameter mathematical model of interior ballistics recently adopted by the The Technical Cooperation Program (TTCP), and therefore it permits validation of that model. While the TTCP model is limited to a Lagrange pressure gradient equation, IBRGA also permits using a gradient equation which takes into account the chambrage of the gun. Calculations with IBRGA agree with the results of gun firings, which slow higher muzzle velocities for guns with chambrage than for guns with chambers of constant diameter. IBRGA is used to slow gun optimizations performed with Lagrange gradients for guns without chambrage lead to nearly-optimal propellant grain dimensions for use in guns with chambrage.
This report documents IBRGA thoroughly. It includes comparisons with IBHVG2, a complete FORTRAN listing of the IBRGA code, and sample inputs and outputs.
IBRGA는 총포의 강내탄도 성능을 컴퓨터로 시뮬레이션하기 위한 간단한 FORTRAN 코드입니다. IBM PC만큼 작은 컴퓨터에서도 실행할 수 있습니다. 이 코드는 최근 The Technical Cooperation Program(TTCP)에서 채택한 강내탄도학의 집중 매개변수 수학적 모델을 기반으로 하며, 따라서 해당 모델의 검증을 가능하게 합니다. TTCP 모델은 라그랑주 압력 구배 방정식으로 제한되지만, IBRGA는 총포의 chambrage를 고려한 구배 방정식도 사용할 수 있습니다. IBRGA를 사용한 계산은 chambrage가 있는 총포의 발사 결과와 일치하며, chambrage가 있는 총포의 총구 속도가 일정한 지름의 공간이 있는 총포의 총구 속도보다 느립니다. IBRGA는 chambrage가 없는 총포의 라그랑주 구배로 수행된 느린 총구의 최적화를 위해 사용되며, chambrage가 있는 총포의 경우 거의 최적의 추진제 입자 크기를 제공합니다.
이 보고서는 IBRGA를 철저히 문서화합니다. IBHVG2와 비교, IBRGA 코드의 전체 FORTRAN 목록, 샘플 입력 및 출력을 포함합니다.
