Bubble curtain for hull-type seaplane

Abstract

A bubble curtain for a hull-type seaplane overcomes the disadvantage of universal device planing step caused by reduction of the water adhesion of a current hull-type seaplane, such as great increaseof the flight resistance. The bubble curtain is characterized in that many air outlet tubes are reasonably distributed mainly at two sides of the belly of the body of the bubble curtain from a position below the draft surface of the seaplane to the bottom area of the body of the bubble curtain. When the seaplane is going to take off the water surface, an air compressor in the seaplane is started and conveys compressed air into all the air outlet tubes through a main tube and branch tubes, small bubble strings continuously sprayed by the air outlet tubes cling to two sides of the belly of the seaplane and upwards come up from the water surface, many small bubble strings form two bubble curtains at two sides of the belly of the body and break the balance of the water surface tension of mostof the contact surfaces of the bubble curtains and the seaplane, so the water adhesion is greatly reduced when the seaplane leaves the water; and one-to-one planing step design of the universal devicegreatly reduces the flight resistance, so the aviation fuel is greatly saved.

Description

technical field [0001] The present invention is a device for a hull type seaplane - an air bubble curtain for reducing water body adhesion. Background technique [0002] At present, when the hull-type seaplanes around the world take off on the water surface, in order to reduce the adhesion of the water body, they usually adopt a stepped design near the water surface of the seaplane body. When the seaplane leaves the water body, it can reduce the adhesion of the water body. Focus, but greatly increased flight resistance, thereby wasting aviation fuel. Contents of the invention [0003] In order to solve the shortage of step-off equipment for reducing water body adhesion of current hull-type seaplanes, such as greatly increasing the flight resistance, the invention presents a kind of air bubble curtain. Mainly, many air outlet pipes are reasonably distributed. [0004] When the seaplane is about to take off on the water surface, start the air compressor in the seaplane, an...
