Description

  The present invention relates to a flying object launching apparatus that launches a flying object using, for example, a launch tube.

  In general, this type of projectile launching apparatus is provided with a rear lid provided with, for example, a thin resin film at the rear end of the launcher, and the projectile is inserted into the launcher. In such a projectile launcher, when the projectile in the launch tube is ignited, a high-temperature, high-speed blast (compressible fluid) is generated from behind, and this blast breaks the film of the rear lid. It is discharged outside the firing tube.

  By the way, when this blast is sprayed unevenly into the launch tube, the reaction force exerts an uneven force on the launch tube, which adversely affects the flight of the flying object. It is required to be configured to be smoothly discharged out of the cylinder.

As a proposal regarding such blasting, there is known a configuration in which an injection gas deflection plate is arranged at the rear end of the launch tube, and the blast discharged from the launch tube is deflected backward by the injection gas deflection plate. (For example, refer to Patent Document 1).

  However, the above-mentioned flying object launching device has a problem that the launch tube must be solidified in order to be affected by the blast in the launch tube due to the configuration that deflects outside the launch tube.

  The present invention has been made in view of the above circumstances, and provides a flying object launching device that realizes stable and highly accurate launching of a flying object so as to reduce the influence of blasting with a simple configuration. For the purpose.

  The present invention provides a launch tube into which a projectile is inserted, a rear lid disposed at a rear end portion of the launch tube and provided with a film to be broken by blasting associated with the launch of the projectile, and the launch tube At least one pair of blast deflectors arranged on the rear end side of the inserted flying object and sandwiching the flying object, the flying object launching device was configured.

  According to the above configuration, when the flying object is ignited and blasting occurs, the blasting breaks the film of the rear cover of the launcher and is ejected to the outside, and a part of the pair is disposed with the rear end interposed therebetween. It is discharged to the outside while being in contact with the blast deflection plate. At this time, the pair of blast deflecting plates prevents the influence of the blasting on the launch tube by generating reaction forces in opposite directions that cancel each other perpendicular to the flying direction of the flying object by the blasting abutting.

  Therefore, smooth discharge from the rear cover of the blast is possible, and stable and highly accurate flying object launch can be promoted.
