Description

A kind of electromagnetic wave dirigible

Technical field

The present invention relates to a kind of electromagnetic wave dirigible, particularly a kind of dirigible that flying power can long-range reception microwave energy be provided that self does not need to carry storage battery equal energy source.

Background technology

Electromagnetic wave dirigible is early for one of aircraft of aviation field; this is mainly because dirigible has advantages of outstandingly, such as vertical takeoff and landing, can hover the long period or slowly advance, noise is little, pollution is light; and along with dirigible has been widely used helium filling, safety also improves greatly.

Traditional airship flight power mainly relies on the generating set of self-contained storage power or self equipment, no matter and be that storage power or generating set all exist very large deficiency: the first, power supply or power generation assembly sole mass are larger, and this is just for load and the load of whole dirigible have been brought very large impact; The second, be storage power or power generation assembly it all have a useful life scope, once power supply exhausts or the running out of gas of power generation assembly, dirigible just will quit work, and can only stop the supplementary energy, and this grows distance or work long hours dirigible is very disadvantageous.

Along with deepening continuously of research, a kind of new delivery of energy mode starts to come into people's field of research---microwave power transmission.The transmitting-receiving two-end microwave power transmission system of 1 mile has apart been demonstrated in JPL California, American National jet propulsion laboratory in 1975, and this system receiving terminal RECTIFYING ANTENNA has obtained the DC power of 30Kw; 1987, Canada successfully allow wing length be the aircraft of 4.5 m under the microwave power of 2.45 GHz drives, in low-latitude flying 20 minutes;-nineteen ninety-five in 1994, Japan also carried out the microwave wireless transmitting energy experiment of point-to-point transmission on ground, and receiving device is the large-scale RECTIFYING ANTENNA battle array of 3.2 meters × 3.6 meters, and microwave-direct current conversion efficiency of whole RECTIFYING ANTENNA battle array has reached 46%; In December, 1996, France, under the states such as the U.S., Russia, Japan support, has successfully developed a microwave wireless energy supplying system, and this system is in Reunion Gang Basang valley, electric energy is sent to bottom with the form of microwave beam from the Xiang Duan in valley, has solved in valley little

The life in village, communication electrical problem; In June, 2000, American scientist utilized microwave that one small aircraft is successfully transported into space, indicated that human use's microwave energy makes a breakthrough.

The present invention, according to insufficiency of function and the research to microwave power transmission at present of dirigible in the past, provides a kind of dirigible that can utilize microwave power transmission, can work long hours.

Summary of the invention

Technical matters to be solved by this invention is: for the advantage of the defect existing in traditional dirigible energy supply and microwave current energy supply, provide a kind of novel airship, the advantage such as having can be for a long time, long distance work, and quality is light, simple in structure.

The technical solution adopted in the present invention is: the required energy of dirigible is carried by microwave wireless, and this dirigible is without carrying any fuel, and the unsettled activity of energy is also taken ground picture, is then sent to ground control system.This dirigible comprises: surface em ripple emission coefficient, dirigible system, communication system.Surface em emission coefficient comprises high gain directional transmitting antenna 1, microwave generator; Dirigible 2 systems comprise airship envelope 3, transmission shaft 6, screw propeller 4, fixed mount 5, motor 8, carrying compartment 11, alighting gear 12, rectenna array 7; Communication control system comprises communication control equipment and the ground control center equipment that dirigible carries.

Install the region that high gain directional transmitting antenna 1 can work long hours at dirigible 2 as required, also can, in the passing installation along the line of dirigible 2, in the active distance of microwave power transmission, install.High gain directional transmitting antenna 1 has automatic-posture-adjustment function, can guarantee that antenna 1 points to the rectenna array 7 on dirigible all the time, reduces the impact that changes the energy supply deficiency of bringing because of airship's posture.

Blanketing gas in the air bag 3 of dirigible 2 is mainly helium, can guarantee the safety of airship flight.Carrying compartment 11 is positioned at the below of air bag 3, and on carrying compartment 11, being equipped with can be for hatch door 9, the dizzy window 10 of turnover, before the large window 15 of broad view is housed, bring great convenience to operator's observation; Camera 13 and search lamp 14 are positioned at carrying compartment 11 lower portion above; Alighting gear 12 is arranged on below carrying compartment 11.

Propulsion electric machine 8 is fixed between air bag 3 and carrying compartment 11, and transmission shaft 6 is arranged on the below of air bag 3 by fixed mount 5.Electrical motor 8 drives the direct generation of screw propeller 4 running air thrust to control the state of flight of dirigible 2 by transmission shaft 6.

Rectenna array 7 is fixed on carrying compartment 11 rear portions, is connected with propulsion electric machine 8 by transducing head, the ground-launched electromagnetic wave receiving directly can be flowed to propulsion electric machine 8 after conversion, realizes microwave power.

Communication control system comprises communication control equipment and the ground control center equipment that dirigible carries.The communication control equipment carrying on dirigible is mainly by microcontroller, radio-frequency communication module, image acquisition and processing module, dirigible power train control module and form with his module.Ground control center equipment is mainly made up of radio-frequency communication module, microcontroller and computer system.

Groundwork principle of the present invention is: rely on and receive ground-launched microwave power, the receiving antenna array of installing on dirigible and rectifying circuit are converted to available direct current energy microwave energy, for power and the carrying equipment of dirigible provide the energy, in order to complete the activities such as flight Control & data acquisition, and the data message of collection is sent to ground control system center.The present invention adopts microwave rectification antenna technology, in addition failure-free EMC system design, high directionality emitting antenna and high-power microwave source, guarantee higher conversion efficiency, make microwave energy with very narrow form of beams transmitting, the transmission of concentrating microwaves energy directional, high-performance microwave power source simultaneously, has guaranteed the stable of high frequency stability and microwave beam.

The technique effect that the present invention realizes is: dirigible self can not carry any energy; The transmission of microwave is the impact of climate environment not, works reliably; Stop for a long time sky, safety; Owing to adopting wireless energy supply mode, mechanical equipment is few, lightweight, and dirigible volume is little, and cost is low.
