Abstract

The flight loads analysis was carried out on the aircraft with high aspect ratio flexible wings by using commercial software MSC/NASTRAN. The aerodynamic model for flight loads analysis was corrected, compared with results of the wind tunnel test. And in-house program was developed for pre and post works. In-house program enabling management of much data automatically consists of three modules: 'Construction of the mass distributed model', 'Selection of critical load cases', 'Generation of external loads for structural design'. By utilizing these techniques and programs, the procedure of flight loads analysis was established for effective development of an aircraft.

상용 프로그램 MSC/NASTRAN의 FlightLoad를 사용하여 고세장비 유연날개 항공기의 하중해석을 수행하였다. 풍동시험 결과를 이용하여 공력모델을 보정하고, 항공기의 모든 기동조건을 묘사하기 위한 트림조건을 정립하였다. 또한 항공기 중량 모델링, 설계 임계조건 판단 및 해석용 하중카드 생성 등 모든 업무를 자동으로 생성할 수 있는 프로그램을 개발하였다. 이러한 기법과 프로그램을 이용하여 효율적인 항공기 개발을 위한 비행하중해석 절차를 수립하였다.
