Active flow control device and method for attitude adjustment of airship and fixing device for active flow control device

Abstract

The invention relates to an active flow control device and method for attitude adjustment of an airship and a fixing device for the active flow control device. The active flow control device comprises a plurality of active flow control arrays fixed on the airship, which are placed on the surface of the hull of the airship respectively, wherein opening and closing of a part or all of the active flow control arrays are changed to realize attitude adjustment of the airship; each active flow control unit includes a substrate and an electromagnetic drive vane array; the electromagnetic drive vane array is composed of one or more electromagnetic drive vanes respectively fixed on the substrate through a rotary shaft; and a closed state is formed through rotation of the rotary shaft and fitting of the substrate, or an opening state is formed through forming an angle with the substrate. The active flow control device changes the symmetry of fluid around the whole body of a flying airship to generate a control moment for pitching or yawing, and replaces or matches with control planes and vector propellers to completely control or assist controlling flying attitude of the airship, so that the active flow control device can output a more stable control torque under a high wind speed to complete predetermined navigation.

Description

technical field [0001] The invention belongs to the field of flow control, and more specifically relates to an active flow control device and method for airship attitude adjustment, and a device for fixing it. Background technique [0002] With the progress of aviation technology and material science, airship, as a kind of aircraft with a long history, has developed by leaps and bounds in its design and manufacturing technology. The value in modern military and civilian use has received great attention. Among the low-altitude airships, the heavy-duty airship has attracted a lot of attention because of its large load capacity and its advantages such as direct vertical take-off and landing without a runway. High-altitude airships have become a research hotspot in various countries because of their advantages of long-endurance fixed-point airships. [0003] The main methods of airship attitude control during low-altitude airship navigation are: adjusting the deflection of the...

AI Technical Summary

Problems solved by technology

Therefore, when sailing, even if the wind speed is not high, the airship often has wind interference. Conventional control methods such as rudder surfaces have insufficient control force and cannot complete attitude control, which has formed a great obstacle to the development and application of airships.
