Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle mounted on an aircraft and launched toward the rear of the aircraft.

[0002]

2. Description of the Related Art A conventional air vehicle mounted on an aircraft is shown in FIG. As shown in the figure,
Is mounted on the mother aircraft 02 so that the front of the flying object 01 comes to the front of the mother aircraft 02, and this is launched only toward the front of the mother aircraft 02.

[0003]

As described above, the conventional flying body mounted on the aircraft is fired only toward the front of the mother aircraft, and cannot be fired toward the rear.

The present invention seeks to provide a flying vehicle mounted on an aircraft that can be launched rearward.

[0005]

A rear-launch aircraft-mounted aircraft according to the present invention is provided with a gas ejection device capable of ejecting gas in mutually opposite directions in a plurality of directions orthogonal to the machine axis and forming an angle with each other. , Provided at a position away from the center of gravity.

[0006]

[Operation] Since the initial velocity of the aircraft launched from the onboard aircraft in flight toward the rear of the aircraft is the same as the velocity of the aircraft, for a certain period of time immediately after launch, it will be placed behind the aircraft. Will fly toward. Since the flying body is designed to fly forward, when flying backward, aerodynamically unstable forces, moments,
Vibrations and the like make the posture unstable, making normal flight difficult.

According to the present invention, when the flying body flies backward, the gas is ejected in the opposite directions of a plurality of directions which are provided at a position away from the center of gravity and are orthogonal to the machine axis and form an angle with each other. The possible gas jetting device appropriately jets out gas in each of the above directions to cancel the unstable moment generated, and the flying body can fly while keeping its posture stable.

The unstable moment generated around the axle is corrected by means such as a steering wing or the like after the flying body starts to fly forward.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. Reference numeral 1 denotes a flying body to be mounted on an aircraft 2 serving as a mother aircraft. As shown in FIG. 4, the flying body 1 is mounted on the main wing of the aircraft 2 with its front portion facing the rear of the aircraft 2. Has been done.

Four gas ejection devices 4 are provided at the position of the body 3 which is separated from the center of gravity CG of the flying body 1.
The gas ejecting devices 4 form two pairs, and one of the two gas ejecting devices 4 forming a pair has a horizontal direction Y orthogonal to the machine axis direction X, as shown in FIGS. 2 and 3. At the opposite sides of the machine body 3, the gas 6 can be injected in opposite directions in the Y direction.
The other of the pair of two gas ejection devices 4 is opened at a position facing the machine body 3 in a vertical direction Z orthogonal to the machine axis direction X, and gas is emitted in opposite directions in the Z direction. It can be jetted. Reference numeral 5 denotes a steering wing attached to the body 3.

A vernier rocket, a gas generator, accumulated cold gas and the like are used as a gas source of the gas injection device 4.

Since the initial velocity of the flying body 1 launched backward from the flying aircraft 2 is the same as the flight velocity of the aircraft 2, the flying body 1 will fly backward for a short period after the launch. . Since the flying body is usually designed to fly forward, the attitude changes during this backward flight and becomes unstable.

In the present embodiment, since there are provided two pairs of gas ejection devices 4 which are located away from the center of gravity CG and can inject gas in opposite directions in the Y direction and the Z direction, respectively. By appropriately ejecting the gas 6 from the gas ejecting device 4, the attitude around the Y axis and the Z axis can be controlled.

The attitude control around the machine axis direction (X direction) is performed by operating the steering blades 5 when the flying body 1 starts to fly forward.

In the above embodiment, the gas ejection device 4 ejects the gas in the Y and Z directions which are orthogonal to each other, but ejects the gas not in the orthogonal directions but in a plurality of directions oblique to each other. You may do it. In addition, the gas ejection device may be installed at a plurality of positions in the machine axis direction as needed.

[0016]

EFFECTS OF THE INVENTION The flying object according to the present invention is provided with a gas ejecting device capable of ejecting gas in opposite directions in a plurality of directions orthogonal to the machine axis and forming an angle with each other. It is possible to control the attitude of the flying object when it is flying backwards immediately after being launched, and it is possible to stabilize the flight of the flying object that is launched backwards from the aircraft.
