FIELD: aerostation. SUBSTANCE: transport facility is provided with propeller of ornithopter wing type which is made solid; propeller has symmetrical profile with rigid thickened leading edge and trailing edge which is more flexible and tapering. Transport facility gets in close contact with air mass which possesses property and form of solid body - wedge under definite conditions. One or another surface of wing plane slips off "webs" of this wedge, thus providing for similar effective thrust both at downward and upward swings. EFFECT: minimum of drag and considerable reduction of fuel consumption. |
