Description
Technical Field
The invention relates to the field of unmanned aerial vehicle recovery, in particular to an emergency inflation recovery platform for a sea mountain terrain unmanned aerial vehicle.
Background
With the continuous improvement of unmanned aerial vehicle performance and the continuous evolution of a carrier platform, the unmanned aerial vehicle is gradually expanded from initial relatively single functions to various purposes such as serving as baits, anti-radars, electronic suppression, target shooting, battlefield damage evaluation, communication relay, reconnaissance and battle, and the like, and the role of the unmanned aerial vehicle is increasingly important. In addition, unmanned aerial vehicles play an important role in 'non-contact wars' in which informatization weapons and intelligent weapons are dominant, and dangerous tasks such as battlefield reconnaissance, anti-submarine warship, amphibious assault, air warning and the like are increasingly widely performed in certain special battle areas, so that sea control and empty control in future wars are mastered, and national defense strength is enhanced. The topography of China is complex, and 5 basic topography types on the global land are distributed in China. The special environments such as deserts, mountain areas, seas and the like bring great challenges to the emergency recovery and transfer landing of the unmanned aerial vehicle. Therefore, the emergency recovery and transfer landing platform of the fixed-wing unmanned aerial vehicle and the helicopter which are researched to face the sea mountain landform has profound significance, and is not only significant for reducing the loss of the unmanned aerial vehicle and increasing the combat radius of the unmanned aerial vehicle, but also an important problem of international general attention.
The unmanned aerial vehicle has stronger fuselage than the unmanned aerial vehicle in general, can carry and not limited by pilot's physiological condition, therefore unmanned aerial vehicle has great military and civilian value. The traditional medium and small unmanned aerial vehicle recovery method mainly comprises the modes of conventional runway recovery, net collision recovery, overhead hook recovery, parachute recovery and the like.
Conventional runway recycling is a recycling mode adopted by most fixed wing unmanned aerial vehicles, and the principle of the conventional runway recycling is similar to that of a piloted plane, and a special runway or an open field is required, so that the flexibility is lacking. In order to shorten the running distance, some unmanned aerial vehicle have an opportunity to install a tail hook at the tail, and the tail hook hooks the interception lock on the ground in the running process, and absorbs the kinetic energy of the unmanned aerial vehicle through the elastic deformation of the interception rope. For sea mountain terrains, the conventional runway recovery method has poor flexibility, and the runway is required to be built on the appointed and relatively flat terrains in advance, so that the emergency recovery requirement of the unmanned aerial vehicle cannot be met.
The net collision recovery mode is that a recovery net is opened at the tail of a ship, so that the unmanned aerial vehicle directly flies into the net, after successful capturing, the height is reduced, and the unmanned aerial vehicle is manually transported out of the net. The typical structure for recovering the collision net of the unmanned aerial vehicle at home and abroad has 4 schemes of a single-net three-rod scheme, a double-net double-rod scheme, a single-net single-rod scheme and a single-net double-rod scheme, wherein the former two schemes need an energy absorption buffer device, the single-net single-rod scheme needs a rotary driving device and a damper, and the single-net double-rod structure mainly carries out energy absorption buffer on the unmanned aerial vehicle by means of elastic deformation of a net body and a bracket without an additional damping buffer device. The net collision recovery mode has the advantages of small space, simple equipment, no landing device, low requirement on landing track tracking precision and maintenance of the net collision speed as low as possible. But has the following disadvantages: 1. when the net is bumped, the transverse speed and the sideslip angle are reduced as much as possible, otherwise, the damage probability of the unmanned aerial vehicle is increased; 2. for unmanned aerial vehicles using propellers, paddles are easy to break or cut off a recovery net when recovering, so that the damage risk and the maintenance cost of the unmanned aerial vehicle are increased, and the preparation time and the working efficiency of a recovery device are influenced; 3. the recovery method has high manual operation amount and is difficult to realize mechanization.
The hook recovery technology is developed on the basis of the net collision recovery technology. The hook recovery system generally mainly comprises a capturing device (unmanned wing tip hook, recovery frame, recovery rope), an energy absorption buffer device and a guiding device. The guiding device guides the unmanned aerial vehicle to the vicinity of the capturing device, after the unmanned aerial vehicle wing bumps into the recovery rope, the recovery rope slides to the wing tip along the wing, the wing tip hook hooks and locks the recovery rope, at the moment, the engine is stopped, then the unmanned aerial vehicle can do rotary speed reduction motion around the recovery rope, and after the swing amplitude is reduced to a certain degree, the recovery is completed by manual removal. The recovery mechanism is simpler and is suitable for being used on ships with smaller space. Meanwhile, the requirements of taking off and landing of the large unmanned aerial vehicle can be met. How to ensure that the drone can slow down in the intended pose is a great difficulty in recycling operations.
The parachute landing recovery is realized by a recovery mode that the unmanned aerial vehicle drives the parachute to reach a recovery area and a proper height, and the parachute landing is realized in a speed buffer mode, so that the parachute landing recovery method is widely applied to low-speed unmanned aerial vehicles. Unmanned aerial vehicle need equip retrieve the parachute, decelerate unmanned aerial vehicle through the parachute to realize contacting ground with less speed, thereby reach the recovery purpose. The method has the advantages of light weight, low requirements on the field, small volume after packaging, relatively low cost, stable performance, simple process, small dynamic load of opening the umbrella and the like. However, the parachute is easily affected by wind, and the error cannot be corrected after the parachute is opened, so that the unmanned aerial vehicle is easily collided with a ground building and the like.
