Abstract

The PID controller with fin angle and thrust as control input was designed based on the aerodynamic data of scramjet system. Flight simulation following a given trajectory which strike the target point after climb and cruise with constant dynamic pressure was conducted. After that, the required thrust for the climb and cruise was calculated and the required fuel flow rate for the hydrogen fuel dual mode scramjet combustor was analyzed. The combustor analysis of this study which conducted on integrated model of independently developed inlet, combustor, nozzles and external aerodynamic models, laying the foundation for the integrated design of the air breathing hypersonic system.

공기 흡입식 극초음속 비행체인 스크램제트의 공력 데이터를 기반으로 하여 꼬리날개 각도와 발생추력을 제어 입력으로 가지는 PID 기반 제어기를 설계했다. 일정한 비행 동압을 가지는 상승궤적과 순항 이후 목표지점을 타격하는 궤적을 기준으로 입력하여 해당 궤적을 추종하는 비행 시뮬레이션을 수행했다. 시뮬레이션 결과에 대해서 초기 상승궤적과 순항 궤적에 대해 비행체 모델에 요구되는 추력을 계산하여 수소 연료 이중 모드 스크램제트 연소기에 요구되는 연료 유량 분석을 위한 연소해석을 진행했다. 본 연구의 연소해석은 독립적으로 개발된 흡입구, 연소기, 노즐, 외부 공력 모델을 통합한 모델에 대해 진행되어 공기 흡입식 극초음속 비행체 통합 설계에 대한 기반을 마련했다.
