Aerodynamics auxiliary equipment for hydroaeroplane and float plane

摘要

(57) Abstract The aerodynamics auxiliary equipment for the float of the hydroaeroplane and the float plane by this invention is supplied and the pressure cord air the extension and the side of the float which consists of essentially the box (1) (11) the bladder of four airtightness which have been located (10) has possessed alongside profit and the float. The bladder (10), it consists the flexible material or the elastomer material which does not have most expansion abilities, and the whole water tight fiber skin layer (9) with is covered with elasticity. The box (1) the edge namely the side section edge (8) and the keel edge (7) it is smoothed in a state where the compressed air is supplied. Therefore, when the aircraft becomes flight state, immediately, drag coefficient C _{D of the} float is decreased suitably. As for the compressed air the aircraft to take off the water from the water surface and be released the occasion where it lands, with that, the edge (7 and 8), those stability (the keel edge (7))For the sake of and the Coanda effect (side section edge (8))It can show those effects in order to prevent.
