    New drone design idea, pull air for lift

    I use the picture to show only concept. Imagine it where the opening where the air comes in is pointed up, where the air moves radial outward and horizontal to ground. I was wonder if it could VTOL. I see that some air may indeed push against the machine. The air moved radially would leave...

    New drone design idea, pull air for lift

    I have read a discussion about a centrifugal fan on a wheel system The fan pulled air to itself and push the air outward from center. Most flying machines that I aware of push air down, as Newton describes. Since air is move downward, but toward machine could a new drone work this way...

    How Do Pressure Differences Affect Centrifugal Fan Performance?

    I have a friend that build something similar to the described fan, which is used for surfaces that are not flat. He said it does have force in direction of the open side if the fan is not fixed to the surface. I believe it is due to pressure Difference. For reaction, I am not sure. I think...

    How Do Pressure Differences Affect Centrifugal Fan Performance?

    I took the liberty of reading the vortex attraction patent. It would have an area of lower pressure, but I do not think the item will be able to move if it is not near a surface. I think it acts as suction cup does to wall. Interesting machine though.
