DZC-1型弹丸章动角及章动角速度测试装置

MODEL DZC-1 PROJECTILE NUTATION ANGLE AND NUTATION ANGULAR VELOCITY MEASURING DEVICE

本文利用调Q红宝石激光器脉冲闪光频率高,单次光脉冲能量强,脉宽窄等特点,研制了DZC-1型测试装置。在同一张感光底板上清晰地获得了弹丸二次瞬态影象,为弹丸章动角及章动角速度的测试建立了一种新的方法。本文着重介绍该装置的工作原理、性能结构、技术指标,主要特征,以及利用该装置获得不同扰动状态下弹丸具有不同章动角时的图片,同时简单介绍章动角的求解方法及所得参数。

In this paper we present our development of the DZC-1 measuring device, in which a modulated Q-laser characterised by higher frequency, higher energy and narrower bandwidth of impulsive flashes is included as its essential element. This device can clearly record, on a single sensitized dry plate, two instant imagines of a projectile at various nutation angles, thus introducing a new method in the measurement of projectile nutation angles and nutation angular velocities. This paper is mainly devoted to the description of operation principles, basic structures and features, and technical characteristics of the DZC-1 device as well as the presentation of pictures of projectiles of different behaviours. Finally, a simple method for calculating nutation angles and some calculation results are also presented here.
