Abstract

A validation study is conducted for the conceptual design and performance analysis of UH-60A Black Hawk in order to establish the conceptual design and performance analysis techniques for conventional helicopters using a single main rotor and a tail rotor. As a tool for conceptual design and analysis, NDARC(NASA Design and Analysis of Rotorcraft) is used for the present study. The conceptual design for UH-60A is successfully validated as compared with the target values. Then, various performance analyses in hover and forward flight are conducted for the UH-60A model obtained from the present design work, and they are compared well with the wind tunnel test, flight test, and previous analyses using various analysis tools. Through this validation work, the conceptual design and performance analysis techniques for the conventional helicopter are appropriately established.

본 연구에서는 단일로터-꼬리로터 형상의 일반 헬리콥터에 대한 개념설계 및 성능해석 기법을 정립하고자 회전익 항공기 개념설계 및 성능해석 코드인 NDARC을 이용하여 UH-60A 헬리콥터에 대한 개념설계 및 성능해석을 수행하였다. 적절히 가정한 임무 형상을 이용하여 UH-60A 헬리콥터의 개념설계를 수행한 뒤 설계 목표 값과의 비교를 통하여 UH-60A 헬리콥터의 형상 및 중량을 적절히 설계할 수 있음을 확인하였다. 더불어, 본 연구로부터 설계된 UH-60A 헬리콥터 모델을 이용하여 다양한 비행 조건에서의 성능해석을 수행한 뒤, 본 연구의 해석 결과를 UH-60A의 성능 시험 및 선행 연구의 해석 결과와 비교하여 본 연구 결과의 타당성을 검증하였다. 그 결과, 단일로터-꼬리로터 형상의 일반 회전익 항공기의 개념설계 및 성능해석 기법을 적절히 정립하였음을 확인하였다.
