摘要:在直升機設(shè)計過程中,準(zhǔn)確預(yù)估各系統(tǒng)的重量非常重要。文章研究了國內(nèi)外現(xiàn)有的直升機機體結(jié)構(gòu)重量估算經(jīng)驗公式,并建立了適用于國內(nèi)直升機機體結(jié)構(gòu)重量估算模型,結(jié)果表明其成功減小了估算誤差。

Abstract:During the helicopter design process, it is very important to accurately estimate the weight of each system. This paper collects and studies the existing domestic and foreign helicopter body structure weight estimation empirical formulas, and establishes a body structure weight estimation model suitable for domestic helicopters with reference to successfully reduce the estimation error.
Key words: helicopter,airframe structure, weight estimation
1前言
重量分析與控制是直升機總體設(shè)計過程中的重要內(nèi)容,重量預(yù)估則是初始設(shè)計階段重量分析與控制的基礎(chǔ),因此需要構(gòu)建直升機各部件的重量估算模型。(剩余4661字)
