  • 20 years ago this might of been impressive

  • Take a piece of paper between your two fingers and blow over it.

    It comes up.

    Aerodynamics First Lesson. This principe ist nearly the same.

  • If you'd be so kind as to demonstrate the foil lifted 'level to earth' and then!... tell us the 1) surface area 2) weight of the foil 3) temperture of the air stream 4) air flow speed. Then, we could get a feel as to any efficiency gains over standard rotor propellor helicoper designs.

  • "It's MegaMaid! She's gone from suck to blow!"

    Is the air blowing or sucking from that machine?

  • @GRATZIANI2002

    Separation of boundary layer.

  • is working..for 15 m/sec....ok..make the speed 50 m/sec..what's happening ?

  • @recoveringcultmember

    Thank you.

  • @IPlayWithFire135 The Coanda effect has to do with a fluid flowing from a nozzle into another fluid. The fluid flowing from the nozzle will cling to a smooth, gently curving surface, if i'ts close to the nozzle.

    Bernoulli doesn't depend on a nozzle.

    Coanda has some patents. If you search google patents for 'coanda' you can find them, and they give an explaination of the principle.

  • @IPlayWithFire135 Bernoulli is wrong

  • nice thank you
