SHESTERENKO'S AIRCRAFT (SAC) Russian patent published in 2010 - IPC B64C39/00 F02K1/36 

FIELD: air transport.

SUBSTANCE: aircraft contains frame for effective load and device for ejector gas acceleration, which nozzles are interconnected and vacuum cavity. In the first example behind the last air-tight nozzles interconnected in rigid or flexible way there is a loose mounted ejecting nozzle with critical cross-section bigger in comparison with critical cross-section nozzle defining consumption for the same air-tight interconnected nozzles. In the second example for air-tight interconnected nozzles one nozzle is introduced into resonance cavity so that gas-dynamic flow leaving the nozzle could collide with gas-dynamic flow in resonance cavity equipped with at least one outlet nozzle. In the third example air-tight interconnected nozzles are installed so that they could rotate relative to rotative axis to which they are fixed by the arm.

EFFECT: efficiency upgrading of energy use of active pulse jet.
