FIELD: engines and pumps. ^ SUBSTANCE: nacelle of double-flow jet turbine engine with high bypass ratio includes internal channel of secondary flow of jet turbine engine and has external housing containing thrust reverser. The latter has the possibility of being changed over from closed position providing secondary flow flowing in internal channel in direct jet mode to open position with opening of the hole in external housing, which redirects secondary flow to diverted jet by bringing thrust reversing means into action. Thrust reverser in open position partially overlaps internal channel so that leakage flow passage is formed in it. When in open position, thrust reverser has reversing flow passage to diverted jet and leakage flow passage through internal channel, the sum of which is equal to flow passage of channel in direct jet mode at closed position of thrust reverser. ^ EFFECT: invention allows reducing the weight and dimensions of nacelle owing to decreasing thrust reverser dimensions. ^ 9 cl, 3 dwg |
