Description

TECHNICAL FIELD

[0001] The utility model belongs to model rocket launching auxiliary device technical field relates to a bottom filling model rocket launcher. BACKGROUND

[0002] In the prior art, model rocket launcher includes using top loading launcher, from the bottom offset about 10cm position into the launcher and single rod with launch sleeve handle launcher;

[0003] Among them:

[0004] ①, the current most model rocket launcher uses the mode of loading from the top. The advantage of this mode is that the operation is simple, and the structure is intuitive. However, when adjusting the height of the launcher, the rocket cannot be directly loaded into the launcher, and the rocket needs to be placed first, and then the height of the launcher is adjusted, which increases the operation steps and reduces the launching efficiency.

[0005] ②, the existing bottom loading mode, but the rocket often deviates from the geometric center of the launcher about 10cm after loading. Although this deviation will not directly affect the launch trajectory or accuracy of the rocket, it may have an adverse effect on the structural design and overall performance of the launcher. Due to the misalignment of the rocket and the center of the launcher, the offset will cause asymmetric force, which will affect the stability and balance during launching.

[0006] ③, single rod with launch sleeve handle launcher, this design supports the rocket through a single support rod, and fixes the rocket by using the launch sleeve handle. However, due to the simple structure of this design, it is not suitable for the launching of high-altitude rockets. The weight of high-altitude rockets is extremely light, and the weight of the entire rocket body is less than 10g except for the engine. Therefore, for such light rockets, any small force or asymmetric support will significantly affect the launch height. Since the launch sleeve handle cannot provide sufficient precise fixing and centering control, it may cause unstable forces during the launching of the rocket, thereby seriously affecting its launch height and accuracy. Therefore, the single rod with launch sleeve handle launcher is not suitable for the launching of high-altitude rockets, especially in situations where the launch height and attitude stability need to be ensured.
