High Coverage Unmanned Electric Powered 2 Nozzles Crop Dusting Helicopters
 
High Coverage Unmanned Electric Powered 2 Nozzles Helicopter with 20 Kilogram Payload Self Programmed Capacity
 
 
Description:

1. The helicopter and its flying control system were developed in response to market demand for aerial agricultural spraying. the small size of farms meant that Manned Fixed-wing crop dusters is uneconomical and safety concerned. It provides much more accurate spraying, at lower cost and lower risk than manned aircraft. Compare to traditional manned aircraft, it does not require a large take off terrain, it could easily take off and land from farms side area, no special track required; its light weight, small size, can be transported with a small size van.
2. It’s characterized by flybarless rotor and lifted tail rotor. Flybarless rotor has a simple structure and low failure rate. Lifted tail rotor prevents from crashing caused by pesticide applying on tail rotor.
3. It carries maximum of 15 kilograms farm chemical. depends on the skill of operator, each trip could spray up to 1.5 hectare of land within 12 minutes, it is 60-80 times more effective than traditional manual hand spraying.
4. The use of ultra-low volume pesticide spraying operation can limit the cost of water and pesticides. Moreover, using remote control allows the operator to stay away from chemical pollution, it’s greatly reducing the harm to the operator.

Competitive Advantage:
 
1. Helicopter VS Quadcopters
Quadcopters don't have any special inherent stability. When you increase power of one of the rotors to pitch, the increasing pitch will not do anything to the power difference and therefore the pitching moment.
The advantage of quadcopters is that the rotors can be fixed pitch while single (or double) rotor helicopter needs complex control mechanism. While this is huge advantage for the small scale devices where each rotor can be powered by its own simple electric motor, the complexity of either additional engines or long transmission shafts would outweigh any advantage from the simpler rotors in full-scale vehicle.
 
 
2. why can't full-scale helicopters use electric motors like the small ones?
        The reason is that when you scale an airfoil up, the lift it produces increases with its area, which grows with the second power of size, but its weight increases with volume, which grows with the third power of size. Therefore models have much more lift for weight and can afford simple but relatively heavy batteries while full-size aircraft need propulsion systems with higher power density.
 
3.Easy Operation
 
    It does not require a runway to takeoff or landing, it takes off vertically. Hanhe BD-1 system has been installed, which effectively lowers the operation difficulty and the risks. Flying at low altitude of several meters, the dusting effect can be controlled in the sight-distance range. It is suitable for all kinds of complex terrain farmlands and the crops and woods of different heights.
 
4. Excellent Crop Dusting
 
        While it utilizes the strong downward rotating airflow to flip and shake the crops when crop dusting, it comes into being a turbulent area above the crops underneath. The crop dusting is very uniform and partial pesticide is dusted on the back of stem and leaf, the quality of crop dusting of which the manpower and other dusting equipment can not achieve.
 
Hanhe Aviation Technology Co., Ltd is an agricultural UAV company based in Wuxi and focuses on research, development, production and application of agricultural spraying UAV helicopters. The company is committed to the field of agricultural robots designed to help Chinese farmers drastically reduce current pesticide application costs and labor time. By utilizing leading technology and experienced staff, Hanhe Aviation is able to provide high-precision equipment for the modernization of agriculture, production service and data management platforms.
Since 2005, Hanhe Aviation began carrying out the R&D of agricultural spraying helicopters. In 2008, the Wuxi municipal government invited the company to move from Shanghai to Wuxi and Wuxi Hanhe Aviation was established, Simultaneously, Hanhe Aviation was rewarded by the Wuxi municipal government for leading the returned overseas entrepreneurship 530 class “A” program, and as a national advanced tech enterprise. During its developmental years, Hanhe Aviation has filed nearly 50 patents, covering many aspects of remote control spraying and aircraft engineering technology, these patents comprise a comprehensive patent protection dome.
