To solve a problem of a conventional flying object in which even if there are differences in the scale of the actuators, such as the method of moving the wings with an actuator and controlling by steering, the use of actuators is indispensable, and it makes difficult to realize downsizing and reducing weight of a flying object and energy saving in it.SOLUTION: A jet nozzle of the present invention is assembled in a manner where a pipe nozzle, a spacer, and an expansion nozzle are coaxially aligned. A plurality of suction pipes is arranged radially around the axis in the vicinity of the joint section of the expansion nozzle to the spacer. During operation of this jet nozzle, since negative pressure is induced in the suction pipe due to the high-speed flow of high-pressure jet gas, the outside air may be taken into the suction pipe by opening outside air solenoid valve arranged on an end of the suction pipe. By adjusting the position and strength of the sucked outside air while individually controlling the opening degrees of these multiple solenoid valves, the jet direction of the jet stream ejected from the flying object is controlled, and the propulsion direction of the flying object is controlled.SELECTED DRAWING: Figure 1

    【課題】従来の飛翔体は、アクチュエータで翼を動かし舵をとって制御する方法など、アクチュエータの規模に大小の差はあっても、アクチュエータの使用は必須であり、飛翔体の小型軽量化、省エネ化の実現を困難にしている。【解決手段】本発明の噴流噴射ノズルは、パイプノズルと、スペーサと、拡大ノズルとが軸心を一致させて組み立てられる。このうち拡大ノズルのスペーサとの接合部近傍には、複数の吸引管が軸心を中心として放射状に配置される。本噴流噴射ノズルでは作動時、噴射される高圧ガスの高速流に起因して吸引管に負圧が誘起されるので、吸引管の端部に設置された外気電磁弁の開口操作より、吸引管内に外気を吸引することができる。これら複数の電磁弁の開口度を個別に制御しながら、吸引される外気の位置、強さを調整することで、飛翔体から噴射される噴流の噴出方向を制御し、飛翔体の推進方向の制御を行う。【選択図】図1
