FIELD: aviation. SUBSTANCE: suction of foreign matter into power plant passages is excluded due to deflecting the lower movable panel whose length is equal to i= 0.2 to 0.21 m upward through angle of Φ= 15 to 20 deg and deflecting the upper movable panel having length of i= 0.25 to 0.3 m upward through angle of Φ= 10 to 15 deg during operation of flying vehicle on ground. Innovation consists in availability of movable panels of air intake passage deflected upward which increases height of location of its leading edges, thus decreasing or excluding vortex generation at inlet of air intake passage and consequently avoiding suction of foreign matter in its duct; besides that, upper movable panel is provided with side ribs moving in housing to exclude attached flow forming closed loop in upper portion of air intake passage. EFFECT: enhanced efficiency. 2 cl, 2 dwg |
