  1. Frequency sweep flight technique is used to collect the flight data of a model helicopter near its hover and low speed working condition, window frequency spectrum is combined to obtain the frequency response of both lateral and longitudinal channels, then weighted fitting method is utilized to obtain the transfer functions of the two channel

    摘要利用掃頻試飛技術獲取了某無人直升機在懸停工作點附近的舵機輸入和直升機動態輸出數據，利用組合窗頻譜分析的方法獲取了直升機橫滾通道與俯仰通道動態的頻率響應特性，利用加權擬合的方法獲取了各自的傳遞函數。
  2. The acoustic noise generated by the rotate point source, uh - 1h rotor in hover and ah - l / ols in forward flight were calculated, and the computed results from several methods were compared with each other and with the experimental data

    採用旋轉點源、 uh - 1h懸停旋翼、 ah - 1 / ols前飛旋翼作為算例，對所採用的各種噪聲預測方法進行了比較。
