Definitions
- the invention belongs to the technical field of aircraft recovery, and in particular relates to a differential target precision docking and recovery system.
- Fixed-wing aircraft can be designed to have advantages such as high speed, long flight time, and large load capacity according to specific mission objectives, and therefore have a wide range of applications.
- fixed-wing aircraft need to reach and maintain a certain speed as a take-off and landing condition, and it is difficult to complete landing in uneven terrain such as the wild, mountains, and cities. This problem seriously limits the application of fixed-wing aircraft.
- scientific research and technology in this field naturally seek assisted landing and recovery methods to enable fixed-wing aircraft to land and recover in the above scenarios.
- the methods for fixed-wing assisted platform landing mainly include: net recovery, wire recovery, and a combination of the above methods.
- Patent CN112373711A uses a typical net-collision recovery method. Since the surface base of the recovery net is relatively large, the tolerance of the system is also large, thus having a higher recovery success rate. However, the disadvantages of net-collision recovery are also very obvious. The recovery net often occupies a large space, and in order to maintain the basic strength requirements of the system, the system structure will also be heavier, so the portability of the system is poor. In addition, since the aircraft randomly stays in a large space after hitting the net, it is not conducive to the subsequent automated storage operation. In actual use, this step is often completed by manual operation. Patent CN114715424A uses a large hanging mechanism to hang the recovery net in the air, optimizing the use of space. But the cost is that the volume and weight of the system are very large. Patents CN112340045A, CN105438494A, CN102040004A, CN106494631A, etc. all belong to this method.

- the torque release can be a complete release or a controllable release according to the design scheme.
- the load isolation device adopts a torque limiting device or sets a controllable physical isolation device between the driver and the rotating pair.
- the torque limiting device is designed to: (1) ensure sufficient torque to enable the manipulator arm rod to have sufficient dynamic movement ability, so as to drive the docking device to dock the aircraft with high dynamics and lock the docking device on the aircraft; (2) after the docking device is locked with the aircraft, the manipulator is pulled by the aircraft, and the impact load caused by this is greater than the setting value of the load isolation device, thereby isolating the impact load from the manipulator drive.

- the control system calculates the new docking area in real time during the process of the aircraft flying to the docking area to achieve accurate and reliable docking.
- the control system is mainly used to run the control algorithm and issue execution instructions based on the feedback data obtained and the information of other parts.
- Its carrier includes one or more of the independent controller of the recovery system, the controller of the recovered aircraft, and the controller outside the recovery system to achieve collaborative implementation.

- the guide rod 302 and the winch 304 work together to provide guidance and deceleration buffering for the motion trajectory of the aircraft 1. In this process, the guide rod 302 and the winch 304 work together to pull the aircraft 1 back in time to complete the recovery task of this stage.
- Embodiment 2 please refer to FIG. 10.
- the size of the mechanical arm 201 can be very small, so the operating space is also small. If it is installed on the base 4, the aircraft 1 needs to fly very low before recovery, which affects safety.

Abstract
Système d'amarrage et de recyclage précis à cible différentielle, comprenant : un sous-système de guidage et de freinage (3) ; un sous-système d'amarrage précis hautement dynamique (2) ; un moyen d'isolation de charge d'impact, utilisé pour libérer une cible dans un processus d'amarrage et de freinage ou optimiser la contrainte du sous-système d'amarrage précis hautement dynamique, et transférer ou transmettre, au sous-système de guidage et de freinage, une charge amenée par la cible à un système d'amarrage et de recyclage ; et un système de commande de détection (5). Le système d'amarrage et de recyclage est doté d'une capacité d'amarrage hautement dynamique de haute précision, de telle sorte que seul un très petit composant d'amarrage doit être utilisé en tant que partie d'amarrage, ce qui permet d'éviter des systèmes de tolérance de grande taille et à haute tolérance fréquemment retrouvés dans l'état de la technique. En raison de la conception de séparation d'amarrage et d'amortissement, le volume d'un bras mécanique de haute précision à haute valeur est réduit pour être très faible, et un composant d'amortissement ultérieur est souvent principalement tiré, de telle sorte que la contrainte de l'intérieur de chaque partie du système est relativement rationnelle, et chaque structure de composant peut être conçue pour être légère.
