If you put a fan in front of airplane wings, how powerful would it need to be?

  1. Feb 4, 2009 #1
    I was just wondering, that if you attached a fan in the front of an airplane wing, would it fly?
    If so, then how powerful would the fan need to be for a small model airplane, say 0.4m and 1kg, to fly/hover? Or if i made wearable wings, and i put them on, how powerful then would the fan have to be? Would a medium-strength leaf blower do the job? Or how about a 3m long 300kg plane?

    Er... isn't that what a "propeller" is?
