The present invention, aspect energy conversion efficiency, for improving transmission voltage, designs and has improved efficient power conversion combination, greatly improves the trans-utilization rate of solar power.
The present invention, aspect flight active force, works power consumption greatly in view of multiple motors simultaneously, goes out a set of efficient low energy consumption multiaxis power system, to improve the flying power of gas dish through Research on experiment design.
Of the present inventionly without popularity dish internal circuit control principle be: the electric current that solar panel produces obtains direct current (DC) by photoelectric conversion and enters controller, controller can mutually be exchanged direct current (DC) is stored in storage battery by charging and discharging, converting direct-current power into alternating-current power is entered to AC load with inverter, again alternating current is offered to brushless AC motor, thereby make motor rotation work; On the one hand, brushless electricity is adjusted the alternating-current voltage/AC voltage of controlling output according to the signal of receiver throttle channel, thereby controls the rotating speed of motor, the pulling force of propeller blades; By receiver, flight attitude and the direction of aircraft are controlled in the output of the electric current to steering wheel, voltage on the other hand, realize the effective control to aircraft by this two aspect.
Principle of work of the present invention is: the characteristic that combines solar powered aircraft and ascending balloon, cleaning new energy solar power and lighter-than-air gas lift are organically combined, and integrate four axle flying platforms, solar power provides continuation of the journey power, and light gas can provide part lift, offsets part and bears a heavy burden, reduce the power consumption of four axle flying platforms, radius flight far away while realizing long boat, four axle flying platforms can be realized spot hover awing, can carrying equipment system carry out correlated activation.
Advantage of the present invention is: (1) is unmanned detecting in high-altitude, and unmanned accurately detecting field widespread use, has boundless market outlook and value; (2) fine day there is zero-emission Driven by Solar Energy, good airworthiness, low cost, the operation of flying, the advantage such as of many uses in the time that can be grown boat.

Detailed description of the invention
As Fig. 1, Fig. 2, shown in Fig. 4, the present invention is achieved like this, it comprises novel PVC membraneous material lightweight air bag 1, solar panel 2, alighting gear 3, inverter 4, screw propeller 5, sun-generated electric power voltage stabilizing and buffer memory group 6, carbon fiber pulling force bearing bar 7, it is characterized in that: solar panel 2 is attached to novel PVC membraneous material lightweight air bag 1 upper surface, novel PVC membraneous material lightweight air bag 1 bottom surface connects carbon fiber pulling force bearing bar 7, carbon fiber pulling force bearing bar 7 tops connect screw propeller 5, described carbon fiber pulling force bearing bar 7 is " ten " font, middle junction is connected with solar power constant voltage power suspply and buffer memory group 6, in solar power constant voltage power suspply and buffer memory group 6, inverter 4 is installed, solar power constant voltage power suspply and buffer memory group 6 lower ends connect alighting gear 3, described screw propeller 5 lower ends are provided with motor 11.
As shown in Figure 3, of the present inventionly without popularity dish internal circuit control principle be: the electric current that solar panel 2 produces obtains direct current (DC) by photoelectric conversion and enters controller 8, controller 8 can mutually be exchanged direct current (DC) is stored in storage battery 9 by charging and discharging, converting direct-current power into alternating-current power is entered to AC load 10 with inverter 4, again alternating current is offered to brushless AC motor, thereby make motor rotation work; On the one hand, brushless electricity is adjusted the alternating-current voltage/AC voltage of controlling output according to the signal of receiver throttle channel, thereby controls the rotating speed of motor, the pulling force of propeller blades; By receiver, flight attitude and the direction of aircraft are controlled in the output of the electric current to steering wheel, voltage on the other hand, realize the effective control to aircraft by this two aspect.
Principle of work of the present invention is: the characteristic that combines solar powered aircraft and ascending balloon, cleaning new energy solar power and lighter-than-air gas lift are organically combined, and integrate four axle flying platforms, solar power provides continuation of the journey power, and light gas can provide part lift, offsets part and bears a heavy burden, reduce the power consumption of four axle flying platforms, radius flight far away while realizing long boat, four axle flying platforms can be realized spot hover awing, can carrying equipment system carry out correlated activation.
On four axle flying platforms of the present invention, four motors that are cross arrangement are installed, the distance of drive motor wheelbase geometric centre equates, when the lift that produces when diagonal angle diaxon is identical, just can ensure balance, can not tilt to either direction; And four a pair of forwards of motor, the mode of a pair of reversion makes the reactive torque balance around vertical axes direction rotation, ensure the stable of four axle courses, what motor adopted is constant force 4822,690 KV, the APC multiaxis oar of 16 cun, the dish body of gas dish, also to a certain extent for four axles provide lift, is realized long boat.
The arrangement mode that MK specifies four spindle motors as shown in Figure 4, front (A), rear (C), right (B), left (D), A, the rotation of C motor clockwise direction, B, D motor left-hand revolution; The rotating speed of four motors does corresponding variation can realize four axles, motion laterally, longitudinally, on vertical direction and yaw direction, in the time that four axles need to forwards move, B, D motor keeps rotating speed constant, A motor speed declines, and C motor speed rises, and the lift that now C motor produces is greater than the lift of A motor, four axles will tilt forward along geometric centre, and blade lift component longitudinally moves before driving four-axial; In the time that four axles want port to turn to, A, C motor speed rise, B, D motor speed decline, make anti-twisted distance left be greater than reactive torque to the right, four axles under the effect of anti-twisted distance to anticlockwise.
The thrusts that four oars produce, exceed or can realize lower than the gravity of four axles own time the motion of vertical direction rise and fall, realize hovering in the time that the lift of oar equates with the gravity of four axles itself; Four axles are combined into one by bindiny mechanism and gas dish dish body, in the time that four axles carry out various flare maneuver, be with the dish of taking offence to do identical action and complete a whole set of flight, without popularity dish, solar panel adds four axles, can follow-on mission when sunny more than 6 hours.
The above; be only the detailed description of the invention in the present invention, but protection scope of the present invention is not limited to this, any people who is familiar with this technology is in the disclosed technical scope of the present invention; the conversion that can expect easily or replacement, all should be encompassed in of the present invention comprise scope within.
