Title:
SHORT-DISTANCE TAKE-OFF AND LANDING THROAT OFFSET-TYPE PNEUMATIC VECTOR NOZZLE BASED ON TRANSLATIONAL MOTION
Document Type and Number:
WIPO Patent Application WO/2019/179102
Kind Code:
A1
Abstract:
Disclosed is a short-distance take-off and landing throat offset-type pneumatic vector nozzle based on translational motion, comprising: tail sections of upper wall faces of front expansion and convergence sections of a second throat (8), which are chosen to be a translational component (6), wherein in a level flight mode, the translational component (6) is tightly attached to upper fixed portions of the front expansion and convergence sections of the second throat (8), the translational component and the upper fixed portions form complete upper wall faces of the front expansion and convergence sections of the second throat (8) and are symmetrical to a lower nozzle wall face; and the translational component (6) translates in a backward and downward direction along a specially designed motion trajectory when the level-flight mode is switched to a short-distance take-off and landing mode, and a gas curtain component (9) for blocking the flow of an airflow is arranged between the translational component (6) and the upper fixed portions to close a circulating channel, and short-distance take-off and landing are achieved.
