A monocopter that can fly even with one propeller "Monospinner"

In the case of "rotary wing aircraft" typified by a helicopter, it is necessary to have a mechanism for canceling the force to rotate the aircraft caused by the rotation of the rotor, so normally it is impossible to achieve stable flight with only one rotor It is considered. Monocopter that can fly like floating in the sky with a propeller like how to break such common sense "Monospinner (Mon Spinner)"Was developed.

I can understand how Monospinner flying in a single shot if I watch the following movie.

The Monospinner: a controllable flying vehicle with a single moving part - YouTube


It is a drone "Monospinner" where a strange machine like a letter of "Y" can fly through the air with a propeller. There is only one rotor in the gray circle part of the image.


A monopolar Monospinner appears to drift in the air while rotating.


With an exquisite balance, you can stop in the air while rotating while centering on one axis that passed in the vertical direction.


Monospinner can also fly to draw a circle by adjusting the rotation speed and rotation timing of the propeller. You can keep flying around a certain range.


This is a typical quad-cotter drone.


As its name implies, you gain thrust with four propellers. In the hovering state, the thrust of the four propellers is even, and the sum is equal to the gravity.


Also, by slightly changing the thrust of each propeller, you can change the posture by changing the roll, pitch, etc.


On the other hand, in the case of a monocopter with one propeller ......


Even if the motor is rotated, the entire aircraft will rotate and it is impossible to levitate.


Looking from the side like this.


When the propeller on the left side of the screen rotates, the rotating moment works with the fuselage on the opposite side of the propeller as a fulcrum.


Therefore, it turns over.


To solve such a difficulty, Monospinner 's Y - shaped fuselage.


While calculating the occurrence of rotational moment, it is designed to obtain a certain lift force upward in the vertical direction while the whole body rotates.


And by changing the rotation of the propeller as the aircraft rotates
It is designed to fly with exquisite balance maintained.



By controlling the rotation of the propeller, it is possible to maintain an exquisite balance and fly ......


If you do not control the rotation of the propeller, it will runaway soon and crash.


It is like controlling a Monospinner's flight using a rod-shaped controller.


As you move the controller like a tact, Monospinner moves to chase it.


Furthermore, picking Monospinner ......


I threw ahead with Eya.


Then, Monospinner returned to its original position like a boomerang. You can see that you have advanced attitude control technology.


This strange aircraft Monospinner was developed by Mr. Chow · Wei Shuang of the Zurich Institute of Technology in Switzerland and Mr. Mark · Muller's team. It seems to have been born in researching minimum operating parts that can control flight.
