It seems to come out at the opening of Laputa.
Speaking of Leonardo da Vinci, it is known for paintings such as "Mona Liza" and "Last Supper", but in the 1480s, hundreds of years ago that human beings fly in the sky, he has a design drawing of an airplane.I was drawing.At that time, there were no materials that could be used for airplanes, and I couldn't actually make such a helicopter -like vehicle, so I didn't know if I could fly.
Reproduce Da Vinci's plane
But I realized that I could fly.Maryland University engineers made drones based on Da Vinci's design drawings and participated in the helicopter design contest.The name is "Crimson Spin" (crimson spin), a small quadcopter, with feathers inspired by the "air screw" design drawn by Da Vinci.By the way, it is said that air screws were originally devised by the idea of pushing the air using the alkimedes screw and flying with that power.
The crimson spin feathers, which seem to have expanded the tip without cork, are made of plastic, but in the Da Vinci picture, it is a man's person to turn it, while this drone runs with battery and electric motors.Like modern drones, when changing the direction, the propeller speed is subtly changed.In the picture of Da Vinci, there is only one rotating body, but it seems that making it more complicated and requires technology like a modern helicopter.
Austin Prete, who participated in the CRIMSON SPIN development to acquire a master's degree, performed a test flight and performed the video at the Transformative Vertical Flight Conference (you can see this article).
"It was really surprising that it actually moved properly," said PRETE, who belongs to the Master of Aerospace Aerospace Aerospace Engineering University.According to this drone, it seems that the swirl of the air is created at the tip of each wing, and the whirlpool turns downward, gaining upward propulsion.
The sound is quieter than a normal helicopter
Humans may not fly around with a design helicopter 530 years ago, but vertical disruption and land -type aircraft are getting more than being used for luggage delivery and empty taxis.Moreover, the unique structure of CRIMSON SPIN is also an answer to several drawbacks that are the tasks of vertical take -off and landing machines.The power of the wind blowing down is smaller than the normal helicopter propeller, and the sound is quieter.
Crimson Spin is about the size of a DJI drone sold to a mass retailer, but PRETE can be expanded by "optimization of shape and scrutiny of performance in various flight systems" and can be a size that can put people on it.I'm saying.He himself has decided to belong to a company after his master's degree, and this study will not be able to go any further, but if he has funds, his research may continue in Maryland University.thing.
And PRETE says.
