Microwave wireless energy transfer system for airship

Abstract

The invention discloses a microwave wireless energy transfer airship, and belongs to the technical field of aircrafts. The airship consists of an oil engine power station, a mains supply, microwave transmitting equipment, a transmitting antenna array, a receiving antenna array, a distribution box, a DC load, an AC load, an airship control unit, airship communication equipment, ground communication equipment, a ground control unit and a pointing tracking servo unit, wherein the microwave transmitting equipment converts electric energy produced by the oil engine power station or the mains supply into microwave energy; the transmitting antenna array radiates the microwave energy to the air; and the receiving antenna array on the airship receives the microwave energy and converts the microwave energy into electric energy for the loads; simultaneously, the airship can acquire the variation of field intensity at a receiving antenna and feeds the variation of field intensity back to the ground; and a ground antenna adjusts the direction of transmitted beams and tracks the position variation of the airship according to the variation of field intensity of the airship at the receiving antenna. The invention breaks through the bottleneck of energy acquisition ways of the airship, provides a new method for energy acquisition of the airship, and is favorable for realizing high-altitude long-endurance flight of the airship.

Description

technical field [0001] The invention relates to a microwave wireless energy transmission system for airships, belonging to the technical field of aviation vehicles. Background technique [0002] Airship, as a lighter-than-air aircraft, has the characteristics of high cost-effectiveness and reusability, and has received great attention in recent years. But existing airship carries engine more as power source, uses the generator that engine is matched with to provide electric energy for the electrical equipment on board simultaneously. Due to the limitation of carrying fuel, the airship needs to return to the field frequently to replenish fuel, so it is difficult to achieve long-term uninterrupted cruising in the air. [0003] Recently, it has been proposed to use solar cells as the energy source of the airship, and use high-power motors to power the airship, thus avoiding the limitation of carrying fuel, but it is still difficult to achieve long-term uninterrupted cruise due...

Due to the limitation of carrying fuel, the airship needs to return to the field frequently to replenish fuel, so it is difficult to achieve long-term uninterrupted cruising in the air

[0003] Recently, it has been proposed to use solar cells as the energy source of the airship, and use high-power electric motors to power the airship, thereby avoiding the limitation of carrying fuel, but it is still difficult to achieve long-term uninterrupted cruise due to the limitation of weather and alternation of day and night

Someone further proposes to use storage batteries as a supplement to solar cells. When solar cells can provide electrical energy, in addition to providing electrical energy for the electrical equipment on the airship, the remaining electrical energy is also used to charge the storage battery; when affected by the weather or at night, solar energy cannot provide electrical energy. In this case, batteries are used to provide electric energy for airship equipment, but this solution requires a large number of batteries and heavy weight, which severely limits the payload weight of the airship.
