autorotation n.自動旋轉;自轉。

autoroute

Gliding descent in autorotation is a maneuver used by helicopter pilots in case of engine failure . it requires considerable skill , and since it is seldom practiced , it is considered quite dangerous 當直升機的發動機失效后,自轉下滑就成為駕駛員實現安全著陸的唯一有效手段,這需要熟練的駕駛技術。

Starting from an altitude of no less than twenty ( 20 ) meters and on a heading parallel to the flight line , with the helicopter inverted and to the pilot right , start your autorotation 機頭保持與航道平行,且高度不得低于20公尺,直升機保持倒飛姿態,向操控者的右側開始執行熄火降落。

By combining with the machining needs of parallel machine tools , the working space and the law along with the variation of its autorotation angle were studied 結合并聯機床的加工要求,研究了工作空間及其隨自轉角的變化規律。

Starting from an altitude of no less than twenty ( 20 ) meters and on a heading parallel to the flight line , start your autorotation 機頭保持與航道平行,且高度不得低于20公尺,開始執行熄火降落。

A three - dimensional rigid body model is used to study the landing of a helicopter in autorotation 首先,建立了一個描述直升機自轉著陸飛行動力學特性的三維剛性體模型。

The landing of a helicopter in autorotation is formulated as a nonlinear optimal control problem 本文將直升機的自轉著陸過程定義為一個非線性的最優控制問題。

The helicopter must complete a 180 degree turn after the autorotation has started 熄火降落的程序開始執行后,直升機必須完成180轉彎的動作。

During the autorotation , pirouette the helicopter a minimum of three ( 3 ) times 執行熄火降落的過程中,機體至少需自旋3圈。

The helicopter does not have to be pirouetting when the autorotation starts 在執行熄火降落的動作之前,機體不須保持自旋。

Repeat the above , but start the autorotation from the pilot left 重覆執行上述的步驟,但由操控者的左側開始執行熄火降落。
