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。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。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。Because of the rotation and revolution of the earth and the moon, and the variety of opposite geography position between lunar rover and earth station brought by them, sometimes the lunar rover will be placed in district which is beyond control of the earth station, so the wandering explorer make use of the metering equipment that the itself takes to carry on control and navigation independently have already become an important development direction
月球車通常藉助地面站通過無線電測控進行導航控制，但由於地球和月球自轉和公轉運動及所帶來的地面站和漫遊車相對地理位置的變化等，有時月球車會處于地面站無法測控的區域內，因此漫遊車利用自身或者著陸器攜帶的測量設備進行自主導航控制已經成為重要的發展方向。In fact, during certification, a region of low altitude and low velocity ( the h - v restriction zone ) is established where it is considered impossible to make a safe descent
然而由於缺乏充分的訓練，自轉飛行過程具有一定的危險性。實際上，在高度和速度的一定范圍內，直升機無法實現安全的自轉著陸。分享友人
