technical field

The present invention relates to the technical field of unmanned aerial vehicles, in particular to a detachable four-bladed biplane unmanned aerial vehicle.

Background technique

With the continuous maturity of remote sensing technology, navigation technology and electronic technology, the production cost of small drones is gradually reduced, and there are more and more types of them, and their application range is more and more extensive. Small drones have brought convenience to the development of industrial and agricultural production and other fields, but they have also brought hidden dangers to public safety. Relevant departments have set up no-fly zones for small unmanned aerial vehicles and gradually introduced relevant management measures. However, there are always incidents such as aircraft loss of control or unidentified aircraft intrusion, and small unmanned aerial vehicles need to be captured or intercepted.

The flight speed, concealment, and intelligence level of modern UAVs have reached a relatively high level. Therefore, high requirements are put forward for UAV interception. The interception of UAVs can adopt the hard killing method of directly hitting UAVs. However, due to the low cost, small size, and flexible flight routes of small UAVs, this method has a low hit rate and will generate residues that accidentally injure people around, so it is not suitable for use in crowded places. If laser weapons or radio interference weapons are used to intercept UAVs, on the one hand, the entire interception system is very complex, huge, expensive, and difficult to use and maintain. Invaded by the enemy. In addition, radio jamming weapons can cause serious electromagnetic pollution to the environment.

After searching, the invention patent application of Chinese patent application number 201410609833.8 discloses a double-layer detachable drone, including an upper extension and a lower extension. It is connected with the lower extension, so that when multiple drones need to be used, the upper extension and the lower extension can be separated, so that the two extensions can work independently, and the operation is convenient. This patent only describes the structure of the up and down detachable UAV, but does not introduce its application.

After retrieval, the Chinese patent number ZL201420040752.6 is an invention patent, which discloses a variable-aspect drone, including a fuselage, an outer wing, a middle wing, an empennage, and a power system ; It also includes a connection mechanism between the outer section of the wing and the middle section of the wing. The outer section of the wing is connected to the middle section of the wing through a connecting mechanism, and the connection structure is detachable. In this application, when an enemy plane is found, there are two combat schemes. One is a one-time attack. Once the enemy plane is found, the outer wing can be thrown away, and its high-speed and high-maneuvering flight performance can be used to directly crash into the target to achieve effective strikes; The other is to attach a warhead to the aircraft. After finding the target, the missile will fly to the target and destroy it. After the UAV returns, the missile can be attached and used again. However, the original UAV in the above-mentioned scheme 1 cannot be reused, resulting in an increase in the cost of the UAV; in the scheme 2, the requirements for the ability of the operator to strike the target are relatively high, and the control is more complicated, which is not conducive to the timely and accurate detection of the intruding UAV. destruction. Therefore, efficient interception of intruder aircraft requires further innovation and exploration.

After searching, the Chinese invention patent with the Chinese patent application number 201410740257.0 discloses a tilting fuselage type hybrid multi-state aircraft with an operating rudder surface. However, the aircraft cannot be separated, and its specific application is not specified.
