Description

  The present invention relates to a spacecraft.

  In the past, meteor phenomena were natural, so there was no way to artificially generate meteor phenomena.

  An object of the present invention is to provide a spacecraft capable of artificially generating a meteor phenomenon.

  In order to solve the above-described problems, the spacecraft of the present invention includes a launching mechanism for launching a projectile, a housing for housing the projectile, a loading mechanism for loading the projectile from the housing to the launching mechanism, and the attitude of the spacecraft. It has a control mechanism for controlling.

  A preferred aspect of the spacecraft according to the present invention is a spacecraft characterized in that the above-mentioned spacecraft is further provided with a directing mechanism that changes a firing direction of the launching mechanism. Another preferred aspect of the spacecraft according to the present invention is the spacecraft according to any one of the above, wherein the projectile includes a propellant and the launch mechanism has a function of igniting the propellant. Another preferred aspect of the spacecraft of the present invention is the spacecraft according to any one of the above, wherein the launch mechanism is a gas gun. Another preferred aspect of the spacecraft according to the present invention is the spacecraft according to any one of the above, wherein the launch mechanism is a railgun.

  According to the spacecraft of the present invention, after the projectile is loaded from the storage unit to the launching mechanism using the loading mechanism, the entire spacecraft is controlled by the control mechanism so that the projectile is put into an orbit that enters the atmosphere. The launching mechanism enters the atmosphere when the launching mechanism is directed by changing the attitude of the aircraft, or by directing the launching mechanism using the pointing mechanism in addition to the control mechanism and launching the projectile from the spacecraft. And emits light, which has the effect of generating a meteor phenomenon.

  FIG. 1 is a schematic diagram showing the basic configuration of the spacecraft of the present invention. As shown in FIG. 1, the spacecraft 1 of the present invention includes one or more projectiles 2, a storage unit 3 that stores the projectiles, a launch mechanism 4 that launches the projectiles, and the storage unit. Is a spacecraft including a loading mechanism 5 for loading the projectile into the launching mechanism and a control mechanism 6 for controlling the attitude of the spacecraft 1.

  Then, the loading mechanism loads the projectile 2 from the storage unit to the launching mechanism, and the launching mechanism 4 launches the projectile 2, whereby the projectile 2 is launched into outer space. Hereinafter, each element of the spacecraft of the present invention will be described.

  A “spacecraft” is a machine that operates in outer space. Specifically, for example, an artificial satellite, a manned spacecraft, a manned space station, or the like. Of these, the preferred spacecraft is an artificial satellite.

  The “projectile” is preferably a projectile having a propellant as a projectile. When this propellant is ignited, the projectile is well propelled. “Propellant” includes black powder, smokeless powder and composite propellant. Of these, the preferred propellant is smokeless gunpowder.

  The “storage unit” is a unit for storing a projectile, and is not particularly limited as long as it can store one or a plurality of projectiles.

  “Launching mechanism” means that when the projectile is provided with a propellant, a preferable mode of the firing mechanism has a function to ignite the propellant. Another aspect of the firing mechanism is a gas gun or a rail gun.

  The “loading mechanism” is a mechanism for loading the projectile from the storage unit into the launching mechanism. Examples of the loading mechanism include those that are controlled to automatically load the projectile from the storage unit into the launching mechanism in accordance with a program stored in advance.

  The “control mechanism” is a mechanism that controls the attitude and movement of the satellite so as to be in a desired state. The control mechanism includes a reaction wheel, a control momentum gyro, a momentum wheel, a magnetic torquer, and a thruster. Further, a combination of these can be given as a control mechanism. Among these, a preferable control device is a reaction wheel.

  A preferred aspect of the spacecraft of the present invention is a spacecraft further including a directing mechanism that changes a firing direction of the launching mechanism.

  Next, the operation of the spacecraft of the present invention will be described.

  Hereinafter, a case where the spacecraft is an artificial satellite will be described as an example. The spacecraft has a reaction wheel mounted on three axes as a control mechanism, and goes around a circular orbit with an altitude of 350 km. The projectile is a projectile with smokeless gunpowder, and the weight of the projectile is 10 g. The launching device is a device that can ignite and launch a projectile corresponding to the projectile. The projectile has a firing speed of 500 m / s. By controlling the attitude of this spacecraft using the reaction wheel, the injection direction of the injection mechanism is directed in the direction opposite to the velocity vector of the spacecraft. When the projectile is launched in this posture, the projectile is thrown into an elliptical orbit having a far point distance of 6728 km and a near point distance of 5225 km. Since the near point distance 5225 km is smaller than the radius 6378 km of the earth, it enters the earth's atmosphere. Projectiles that enter the atmosphere emit light, and meteor phenomena occur.

It is the schematic which showed the basic composition of the spacecraft of this invention.
