Autonomous Flybarless Helicopter Electric Powered Spraying System
Payload 20kg Flight During 25 Minutes
- The helicopter and its flying control system were developed in
response to market demand for aerial agricultural spraying. Manned
Fixed-wing crop dusters had been in use, but the small size of
farms meant that this method was 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 automacally 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.
- It carries maximum of 20 kilograms farm chemical. depends on the
skill of operator, each trip could spray up to 2 hectare of land
within 16 minutes, it is 80-100 times more effective than
traditional manual hand spraying. When spraying pesticides
operates, intense downdraft from the helicopter’s rotation can
split and shake the crops and pesticides will be able to evenly
apply on to the back and the roots of crops. In other words,
comparing to traditional manual hand spraying, the helicopter
offers crops and operator a better protection.
- 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.

1. Helicopter VS Quadcopter
Quadcopters are less stable than helicopters. That’s right! They
might seem pretty stable in many small hobby models, but that’s the
Flight controller and speed controller doing all the stabilization
for the pilot. It would be extremely hard to fly a quadcopter
without the asistance.
Flight controllers are getting better and better it’s amazing how
well it’s working. It leads to the misunderstanding that
quadcopters are more stable than helicopters by nature.
For the quadcopter to maintain balance, each individual motors must
adjust speed to change thrust. If motors on one side are spinning
faster, it will generate more thrusts and the quad will tilt to the
other side. Because quadcopter relies on changing the speed of the
propellers to make yaw, roll and pitch movements (3 dimension
movements), how fast it can change the motor RPM (rotation per
minute) determines how agile the quadcopter is.
Apart from the electronic speed controller, this is also very much
depends on the inertia of the propellers. As you can imagine,
generally the bigger and heavier the props, the harder it is to
slow down or speed up. Therefore that contributes to the less agile
and unresponsive characteristics of a large quadcopter. Just like
stopping a bicycle is easier than stopping a train.
2. 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.
Accurate dusting can be achieved for different crops in the
adjacent farmlands. Due to BD-1 installed, the dusting operation
can be mastered via simple training.
The dosage of pesticide is reduced, so it can minimize the
pollution of pesticide to the environment and crops. It is not
harmful to the operator in the distances when dusting, and the
labor intensity is reduced dramatically.
