printed UAV convertable from helicopter to airplane mode. 5 times more long flight, 10 times more speed than multicoper. Reactive forced, solar and wireless powered
The UAV as a self-flying propeller, capable of turning wing blades from helicopter mode to airplane, which gives range, speed and carrying capacity more than multicopters
This gives a strong advantage for the delivery of goods, which is attractive for both postal companies and online stores like Amazon. Also additionally charge with a printed light solar battery and wireless charging from the laser and microwaves
The main problem with using drones is their short flight time. The required power consumption is on average 1 W per 7-10 grams.
The average time for flying a drone is now about 10-15 minutes, although the lightest models can fly up to half an hour.
At the same time, the energy efficiency of gliders is 1 W per 25-30 grams, but their use is limited due to the difficulties of take-off and landing and the inability to hang over a certain place.
Thus, the problem of combining the advantages of a fixed and rotating wing is still present, primarily because of the possibilities of vertical take-off. The most common solution in the form of rotary-wing aircraft, in which propellers can be rotated 90 degrees.
There is also a design like mono-copter, which is a screw with one blade, or half of an airplane with one wing rotating around its axis. A similar construction in nature is realized in the maple leaf.
Earlier, DARPA in 2008-2011 financed the mono-copter Samarai
Description of the solution. The flying device "Screw-wing" in the main mode is essentially a flying propeller, in which the wings play the role of blades. Wings are driven by a stream of air from the rotating nozzle at the end of the wing. A jet of air is created by an air compressor sucking air from above and leading the compressed air inside the wings to the nozzle. Moving vertically and horizontally occurs due to the rotation of the wing and adjustment while air from the nozzles on the wings
When you rotate one of the wings 180 degrees, the UAV passes from helicopter mode to airplane, which allows you to increase speed and ease of control.
In the "airplane" mode, the device can be used for long-distance transportation, and in hover mode - maneuver in conditions of limited space. The UAV is able to switch between the two modes, being in the air: its wings turn into a rotor, revolving around the central module, like a helicopter with one blade.
The effectiveness of the Screwwing UAV significantly increases with additive production
Due to the large active area, the UAV can receive a significant amount of energy, up to 50%, from thin, light and efficient solar cells, which we can print and laser microwave wireless power
