The guide rail sliding table bracket 12 comprises a support frame 121 fixedly connected to the launcher base, and a rotating bracket 122 capable of rotating along with the adjustment of the angle of the guide rail sliding table is arranged on the support frame 121. The rotating bracket 122 mainly plays a role in supporting the guide rail sliding table, and can also be adjusted along with the angle adjustment of the guide rail sliding table when the pitch angle adjusting support rod 11 adjusts the emitting angle of the guide rail sliding table, so that the rotating bracket 122 can better support the guide rail sliding table. In the embodiment, the rocket launching base is an aluminum plate and is fixedly connected to the hard ground through expansion bolts, and the azimuth angle for rocket launching can be adjusted through the rocket launching base.
The power launching cradle is mainly applied to training and test launching. When training at ordinary times and carrying out some new technical verification launches, the safety problem caused by the engine without the propellant is guaranteed, and the launching cost is also obviously reduced. Can meet the requirements of most learning training and research and bring convenience for the research. The launcher of the invention can also provide power-assisted launching for various aircrafts, unmanned planes and the like.
