What is the epoch-making point of the drone "DuoCopter" which is vertically long and has only one feather at the top and bottom?

With only two motors and feathers, Drone realizes the same level of stability as a normal quad-cotter "DuoCopter"is. As the number of components decreases, the overall weight is light, the electricity consumption is reduced, not only enables more efficient flight but also reduces the development cost per drone, and creates various advantages It is.

You can see how the DuoCopter is actually flying from the following movie.

The blue drones on the ground are DuoCopter.


Flight began as the propeller began to turn.


The DuoCopter uses innovative algorithms to float the aircraft with just two engines.


The propeller attached to the two engines has its rotation speed adjusted for each rotation.


When looking from the top of the propeller, turning around the left half circle will increase the number of revolutions quickly, while turning around the right half the revolution will go down and slow down.


According to the difference of this turning force, it will be able to control front and back, left and right from the difference between left and right lift force.

There are places in the movie where you change the direction of traveling.


There is an arm from the main body to the propeller part of the quad copter, and the red part in the following image hinders the airflow of the propeller.


Because DuoCopter is designed with the space under the propeller empty, it can fly more efficiently than quad-cotter without disturbing the air flow. Also, like the regenerative brake, it is also possible to charge the battery with the rotation of the propeller,FlywheelIt is designed to be able to operate with high efficiency as when wearing.


One propeller of DuoCopter is designed to be large but it is about the same size as the quad-cotter's four propellers. Rather than spinning four small propellers, it is more efficient to turn two larger propellers, noise becomes smaller, and electricity consumption is less. In addition, since only two motors are enough, wiring that extends from the battery can be dramatically reduced, and the advantage of being able to simplify the machine design compared to conventional drones also arises.


Less parts will lead to a reduction in the possibility of failure, so it will be a more durable drone. For example, when a quad-cotter falls and receives an impact, it may break each arm of the propeller, but if two propellers are placed on the top and the landing arm is attached to the bottom, it is designed as a shock-resistant drone It seems possible to do.


Besides, since considerable size reduction is possible compared with the conventional quad-cotter, thinking about designing a drones hard to find from people and designing an inexpensive drone that minimizes the component parts Yes. Also, the algorithm for rotating the propeller of DuoCopter can be adjusted so that the propeller can not be seen when shooting with the camera. As a result, it is now possible to install cameras in places where installation was impossible due to the positional relationship of the propeller.

DuoCopter does not generate downforce during high-speed flight like ordinary quad-cotter, so it is suitable for long distance flight.



Also, using the technology of DuoCopter, if it is an airplane type aircraft, it will enable stable flight with a single engine.


You can also design one drone "Monocoptor" with an engine with three blades attached to the body and a rotating propeller on top as follows.


Being a developer of DuoCopterDirk BrunnerIs also a Guinness record holder "using the quad copter to" rise 100 meters in the world ", and you can see the movie containing the moment when you actually set the record.

This is the drone developed by Dirk Brunner who rises in the world fastest.


On the site, officials are watching the start of the drone departure.

It was approved for the Guinness World Record as it reached at 100 meters above the building group at 100 meters above the ground in 3.871 seconds, the fastest speed in the world.


You can see how high it is rising when you look directly under the drones.


It's too fast to see the appearance of Drone, but in the second half of the movie the drones are showing up at 1/2 speed. That's why people with such technological skills developed this drone "DuoCopter" which is vertically long and has only one blades on the top and bottom.
