Each component of unmanned plane of the present invention is installed as the prior art, provides Figure 10 and refers to, generally speaking, branch of the invention The unmanned plane of support assembling is lighter by 15% or so than the unmanned plane that existing support frame (turmeric F450 rack) assembles;Practical flight operation When, power supply is opened, controller is held and provides flight requirement, after flight controller reception flight requires, comprehensive locator The letter of (PX4FLOW light stream sensor can reach 250Hz in outdoor renewal speed, and renewal frequency indoors has 120Hz) Breath, then output order to electricity adjusts device, and electricity adjusts device to control propeller motor operation, and unmanned plane takes off;Image acquisition device shooting is shone Existing conventional equipment is transmitted to by flight controller after piece.About 1.9 kilograms of unmanned plane weight of the present invention, use specification for 11.1V/ The battery of 7500mAh can be with non-stop flight 33 minutes or so (25 DEG C);Propeller motor of the invention is constant force external rotor brushless Direct current generator is shown in that Figure 11, Figure 12 are its electric current pull-up curve, it can be seen that during being applied in combination with paddle, maximum can Supply the pulling force of about 1kg, it is therefore apparent that the pulling force of four motors supply is about equal to 4kg, this is entirely to weigh more than body itself Amount.In addition when passing through the confined space, for example, between door, two trees, window, image acquisition device (optical depth in domestic ratio difficult to understand Camera, there are three cameras, see Figure 13.Can identify front door, the confined spaces such as window apart from size, then this number It is transferred to UAV Flight Control device according to according to available circuit, then judges whether to start straight line by flying the built-in existing program of control Push rod) range data conventional method is transmitted to flight controller after, flight controller can be according to existing method than relatively limited sky Between with unmanned plane size, specially flight controller conventional capability, thus judge whether enable rotating electric machine, if enable if fly Line control unit output order is to rotating electric machine, so that rotary wing arm, reduces unmanned plane overall dimensions, after the confined space, Restore the original state of rotor arm, keeps flight stability;Method control unmanned plane alternatively, it is also possible to be observed by controller leads to Cross the confined space, for example, when controller's discovery need to reduce distance can just pass through the confined space between rotor arm when, hold control Device processed provides requirement, and after flight controller receives requirement, output order to rotating electric machine is run, so that rotary wing arm, reduces Unmanned plane overall dimensions, and will not excessively rotate, after the confined space, restore the original state of rotor arm, keeps flight Stablize;Figure 14 is rotor arm rotary reference figure, for example when needing to reduce width, A rotor arm holds together with B rotor arm rest, C rotor arm and D rotor arm rest holds together, and process does not influence unmanned plane during flying, this is creative place of the invention, passes through it compared with the prior art His method passes through the
