In order to achieve autonomous landing, a micro helicopter should have the ability to recognize the landing target (a helipad). 为了实现微型直升机自主着陆,需要使其具有自主识别着陆目标的能力。 更多例句>> 6) Automatic landing 自主着陆 1. For solving UAV s automatic landing in all weather, a...

In this situation, pilots typically perform an autorotation maneuver to a safe landing, which demands great skill on the part of the pilot. Similarly, unmanned helicopters can encounter engine failure during autonomous operations. Typically, an autorotation maneuver of a helicopter under engine failure...

One of their latest achievements wasteaching the bot the emergency landing technique autorotation.Autorotationis used wh...
If there is a suitable landing spot within the aircraft's gliding or autorotation distance, an unplanned landing will often result in no injuries or significant damage to the aircraft, since powered aircraft generally use little or no power when they are landing. WikiMatrix 可用...
