Abstract

As the survivability of an aircraft in the battlefield becomes a critical issue, there is a growing need to improve the survivability of the aircraft. In this study, the survivability of an UCAV associated with plume IR signature was investigated. In order to analyze the survivability of the aircraft, the lock-on range and the lethal envelope, defined as the IR detection distance of the aircraft and the range of shooting down by the missile, respectively, were first introduced. Further, a method to calculate the lethal envelope for the scenario of surface-to-air missiles including the vertical plane was developed. The study confirmed that the red zone of an UCAV shows a substantial difference in the zone size as well as the characteristics in the upward and downward directions.

전장에서 임무를 수행하는 항공기의 생존성이 위협을 받음에 따라 항공기의 생존성을 향상시키기 위한 연구의 필요성이 커지고 있다. 본 연구에서는 항공기 Plume IR 신호에 관련된 무인전투기의 생존성을 분석하였다. 항공기의 생존성을 분석하기 위해 먼저 항공기의 IR 탐지거리인 Lock-on Range와 미사일 격추 범위인 Lethal Envelope 개념을 도입하였다. 또한 수직면 기준 분석을 포함하는 지대공 미사일에 대한 Lethal Envelope를 계산하는 기법을 개발하였다. 계산결과 무인전투기의 Red Zone이 고도 위 방향과 아래 방향의 특성 뿐만 아니라 정량적인 Zone 사이즈에서 상당한 차이가 생김을 확인하였다.
