Abstract

Developments in aircraft require safety verification through flight testing for many hours with prototype design and production. The test evaluation step of performing flight tests was an important process that determines the success in the development of the system. In particular, safety development through flight tests in the armed flight test is important for the development of attack helicopters. In the development of attack helicopters, the evaluation period and cost related to the armed flight test are closely related to the required ammunition requirement. Therefore, this paper presents the amount of ammunition required for the military flight test between attack helicopter developments through an analysis of the AH-1 helicopter in a similar case and ADS-44-HDBK of military specification. The AH-1 can be used to calculate the ammunition demand by considering the exclusion of redundant firing tests and configuration differences. In the case of the machine gun-equipped configuration, approximately 10,500R was required, and approximately 324R was required in the case of a rocket-mounted configuration. In addition, if the armed integrated bench is used properly, it is expected to promote efficiently the flight test in the armed flight by identifying the possible risk factors with armed flight tests and excluding them.

헬기와 같은 항공기의 신규 개발에는 시제품 설계 및 제작과 함께 많은 시간동안 비행시험을 통한 안전성 검증이 요구된다. 비행시험을 수행하는 시험평가 단계는 시스템의 개발에 있어 성공을 좌우하는 중요한 과정이며, 특히, 공격헬기 개발을 위해서는 무장분야 비행시험을 통한 안전성 검증이 매우 중요하다. 이러한 공격헬기의 개발에 있어서 무장분야 비행시험 관련 시험평가 기간 및 비용은 비행시험의 소요탄약 발수와 밀접한 관계가 있다. 따라서, 본 논문에서는 미 군사 규격인 ADS-44-HDBK와 유사 사례로 AH-1 헬기의 분석을 통해 공격헬기 개발 간 무장분야 비행시험에 요구되는 탄약소요량을 제시하였다. AH-1 헬기의 사례 분석을 통해 중복 사격시험 배제 및 형상차이를 고려하여 탄약 요구량 산출이 가능하며, 기관총 장착 형상의 경우 사격시험 관련 탄약이 약 10,500R 요구되고, 로켓 장착 형상의 경우 사격시험 관련 탄약이 약 324R 요구된다. 또한, 무장통합벤치를 적절하게 사용을 한다면 무장분야 비행시험간 발생 가능한 위험요소 식별하여 미연에 배제함으로써 무장분야 비행시험의 효율적 추진이 예상된다.
