锦义40—2型双腔土火箭,有两个燃烧腔,它以两腔接力推进的方式提高射程。垂直高度达3,200米。具有射程高、飞行稳定、方向性好等优点,适于人工防雹和人工降雨作业。一、构造与工艺锦义40—2型双腔土火箭,由箭头、箭尾、尾翅三部分组成(见图)。 1.箭头:用于而轻,易加工的杂木车制而成。要求锥度要好,外形呈抛物线形,对称性好,以利于加大速度、提高射程、飞行稳定。箭头长 Jinyi 40-2 double-cavity soil rockets, there are two combustion chamber, which is to promote the two-chamber relay way to improve the range. Vertical height of 3,200 meters. With a high range, flight stability, good direction, etc., suitable for artificial anti-hail and artificial rainfall operations. First, the structure and technology Jinyi 40-2 double-cavity soil rockets, arrowheads, tail, tail fin three parts (see photo). 1. Arrow: Used for light and easy processing of miscellaneous wooden car. Requires taper is better, the shape of a parabolic shape, symmetry is good, in order to facilitate increased speed, improve range, flight stability. Long arrow
