    Research of exhaust-screen devices for jet-engine
    (Національний авіаційний університет, 2016-08-19) Kapitanchuk, Kostiantyn; Bohdanov, Mykola; Grekov, Pavlo; Капітанчук, Костянтин Іванович
    The article addresses scientific issues of design of exhaust screens as the most common and reliable method of protecting aircraft from guided infrared homing head missiles and surface-to-air missile systems. The array of experiments was conducted for different types of jet engines, all of which achieve forward thrust from the principle of jet propulsion: turbojet, turbofan, turboprop, and ramjet. Using non-axial flow turbines result in a drop of thrust power. For purposes of reducing energy loss and achieving less field flow fractionation, static exhaust blades should be used.
