Propelled, seemingly, mostly by propellers with rotating blades; these also intended to create lift, rather than fixed aeroplane; on lift: "As is well understood, the greater the number of the square feet of air a kite passes over in a given length of time the greater is its supporting or lifting power per unit of surface, since the cushion of air beneath the kite forms its actual support, and the more air passing beneath it in a given length of time the larger is this supporting cushion per unit of surface..."
- Tech classes: CPC B64C5/04 Noseplanes
