스크램제트 추진기술에 대한 최근 개발동향과 주요기술을 분석하였다. 스크램제트엔진은 지난 10여년간 급속한 기술 발전으로 지상시험에서 비행시험 단계에 접어들고 있으며, 수년 내 실용시험을 목표로 활발하게 연구개발 중이다. 광범위한 비행 마하수를 만족하는 이중연소램제트와 이중모드램제트 형태의 엔진은 각각 군용과 민수용으로 개발되고 있으며, 복합엔진은 차세대 우주발사체의 대안으로 개발되고 있다. 엔진 작동 특성의 미케니즘에 대한 정확한 이해와 이에 상응되는 기술, 흡열연료 및 CSiC 복합재료를 사용한 내열 문제 해결, 가변 흡입구와 노즐을 이용한 안정된 추진력 구현을 목전에 두고 있다.

Abstract

A technical analysis of current scramjet and combined-cycle engine is presented. Substantial research has been pursued to characterize the operation mechanism of scramjet propulsion, especially in the areas of flame stabilization and system integration, dramatically over the years in support of both military and space access application. Major technology that had significant impact on the maturation of scramjet propulsion technology are dual combustion ramjet, dual mode ramjet, and combined cycle engine to cover a typical wide rage of flight, up to flight Mach number 10. Notable are the fundamental and practical techniques, for instance, scram propulsion itself, thermal relaxation and protection using endothermic fuel and/or CSiC composit materials, and design/manufacture of movable intake and nozzle, to realize high speed propulsion system in near future.
