4). wireless monitoring
For obtaining radio target frequency bands signal, the relevant information of echo signal, the technological means such as the reception taked, monitoring, identification, analysis, record.
5) many rotors (multiaxis) aircraft
Multi-rotor aerocraft is also Multi-axis aircraft, by the flying platform organized power system more and form, generally common are four rotors, six rotors, eight rotors ... 18 rotors, even more rotor compositions.Electronic multi-rotor aerocraft drives screw propeller to form single group rotor power system, by inertial navigation system, flight control system, navigationsystem, electronic governor composition control drive part by brushless motor.Aircraft can carry the lift-offs such as imaging equipment, Communication Equipment, collection equipment, special equipment as flight carrier, can reach the height (0-500 rice) of traditional approach out of reach.
Multi-rotor aerocraft is different from the feature of other aircraft:
A) multi-rotor aerocraft has obvious advantage with the structure of its uniqueness with succinct system architecture compared with conventional aircraft.
B) move aircraft using Hi cell as energy with oil compared with noise lower, low-latitude flying can be realized and not easily discover.
C) vertical takeoff and landing can just can stabilized flight at comparatively narrow space, and determines to have not by the advantage that place limits compared with rotor aircraft.
D) (only motor bearings the is mechanical part) maintenance compared with conventional helicopters (having more complicated mechanical part and drive mechanism) of simple mechanical part composition is quite simple.
E) clear superiority that volume is little, lightweight, load-carrying is greatly multi-rotor aerocraft, by FHP-Z617, aircraft deadweight 2kg, can carry and comprise the weight of battery pack up to 4kg, load-carrying ability is 2 times of own wt.And development size is less than a sq m, the portable transportation case of 70*65*35 after folding, easily can be received into together with accessory device.
F) complete machine all-electronin increases steady, simple to operate.Autonomous navigation can realize full automaticity flight.The power system of excellent performance provides the flight attitude of maneuverability, and wind loading rating is strong.
Many rotor flyings system can be widely used in agriculture low-to-medium altitude and sow seeds, sprays insecticide, the supervision of security monitoring, forest extinguishing, the condition of a disaster, emergency communication, electric power application, marine applications, weather monitoring, aerial survey of taking photo by plane, also will be developed further to the application of more than 30 the industry aspects such as aerial exploration, noiseless investigation, border patrol, nuclear radiation detection, mineral exploration aviation, traffic patrolling in addition.
