NACELLE OF AIRBORNE VEHICLE ENGINE, AND AIRBORNE VEHICLE CONTAINING SUCH NACELLE

摘要

FIELD: engines and pumps.;SUBSTANCE: nacelle includes the wall concentrically enveloping at least partially the jet engine and forming together with the latter the internal annular channel of fluid medium flow. Annular channel is provided with flow outlet passage section on downstream end of nacelle wall. Nacelle includes devices for movement upon command of one part of nacelle wall in order to change the flow outlet passage section through which the larger portion of flow flows. Such movement forms one hole in the nacelle wall, through which small portion of flow flows naturally, which is called leakage flow. Besides, nacelle includes fluidics device influencing on the flow so that leakage flow can flow along external surface of some part of downstream located nacelle wall at least of one specified hole. The other object of this invention is airborne vehicle containing the above described nacelle of jet engine.;EFFECT: invention allows improving jet thrust.;13 cl, 7 dwg
