내추락성 요구도 개정을 위한 미 육군 헬기 사고사례 분석 고찰

군용 헬기 내추락성 설계를 위한 대표적인 기준문서는 MIL-STD-1290 및 항공기 추락생존 설계지침서(ACSDG)로서, 두 문서가 최종 개정된 것은 1980년대이다. 다양한 미 육군 헬기 사고사례 분석결과를 감안할 때, 신규 개발 항공기에 적용하기 위한 적절한 내추락성 설계지침서는 존재하지 않는다고 볼 수 있다. 본 논문에서는 새로운 내추락성 설계기준(FSCC)의 근거를 제공한 미 육군 연구개발사령부(RDECOM) 주관으로 수행된 미 육군 헬기 사고 분석결과를 고찰하고 재정리하였다. 이 분석에서는 군용 헬기 추락사고의 결과들을 체계적으로 분석하고 정량화함으로써 새로운 설계기준문서의 정량적 기준을 제공하였다. Representative crashworthiness requirement documents for military helicopter are MIL-STD-1290 and the Aircraft Crash Survival Design Guide(ACSDG) which were lastly revised in the 1980's. Taking analysis results of diverse U.S. Army helicopter mishaps into account, we can say that adequate guidelines do not exist to ensure crashworthiness of new generation aircraft. In this paper, U.S. Army helicopter mishap analysis conducted by U.S. Army Research, Development and Engineering Command(RDECOM) is readjusted to review the basis of new crashworthiness design criteria for military helicopter, in other words, Full Spectrum Crashworthiness Criteria(FSCC). This analysis effort is a part of FSC development. This effort was to research and quantify the dynamics of military aircraft crashes to be used as the quantitative basis for new design criteria.

Missile System Modeling in a Distributed Virtual Environment

In April 2003, The U.S. Army Research, Development, and Engineering Command (RDECOM) conducted an experiment called the First Application (1stApp), using a distributed virtual environment across a wide area network. The two objectives of this HLA-based distributed simulation were to establish a modeling and simulation cost/schedule/performance baseline for the development of a target distributed virtual environment for Future Force technical experimentation and to match tactics to physics to produce realistic expectations of the technical performance of networked fires for the U.S. Army Future Combat Systems (FCS). The core set of models and simulations for this event was developed and provided by the networked fires using Non-Line-of-Sight Launch System (NLOS-LS) Science and Technology Objective (STO). In particular, NLOS-LS developed models and virtual simulations of the NLOS-LS missiles and Mission Management Application (MMA), including modeling of the LADAR seeker on the Loitering Attack Missile (LAM) and the man-machine interfaces to display and utilize LADAR imagery in the battlefield context. This paper describes the LADAR models, missile flight models, MMA virtual simulations, LADAR visualization, and networked fires context that was used to represent NLOS LS in the 1stApp event. It also describes the distributed virtual environment and the simulation architecture that was used to represent the networked fires functionality, through the integration of simulations from a variety of organizations within the RDE Command.
