尾翼是小火箭的主要稳定系统。它在飞行中气动力的作用下,使簡体压力中心后移,产生一种稳定力矩,避免箭体翻滚,从而保证箭体按发射轨所初导的方向飞行。小火箭在生产过程中,由于受到仪器、设备等条件所限,很难使每支火箭的箭头、箭体、箭腔、喷管等诸质量要素都能与箭轴严格对称或偏差在允许值之内,这样,小火箭在 Empennage is the main stability system for small rockets. Its aerodynamic force in flight moves the simplified pressure center backward to produce a steady moment to avoid roll over of the rocket body, thus ensuring that the rocket body will fly in the direction of the initial launch of the launch track. Small rockets in the production process, due to equipment, equipment and other conditions are limited, it is difficult to make each rocket arrow, arrow body, arrow cavity, nozzle and other quality factors can be strictly symmetrical with the axis of the arrow or deviation in the allowable value Within this, the little rocket is on
