【摘要】 精确打击已经是现代战争的主要特点,使常规弹药具有精确打击能力是现代弹药发展的趋势,而弹道修正是使常规弹药具有精确化打击能力的有效手段,弹药弹道修正执行机构是弹药修正化改造的关键技术之一。本文针对弹道修正的特点,以单兵火箭弹道修正为应用背景,提出了一种新型弹道修正执行机构——微型脉冲喷气发动机。根据微型脉冲喷气发动机和半主动激光导引头的工作特点设计了具有一定的弹道解算、弹道控制能力的微型脉冲喷气发动的控制电路。本文的具体工作是从理论上阐述了微型脉冲喷气发动机的工作原理,根据工作原理对微型脉冲喷气发动机原理样机进行了具体设计,并对发动机原理样机在不同的工作压力下进行了推力测试,其中发动机以0.65MPa的压缩空气工作时能达到1.425N的推力。同时根据单兵火箭弹道修正、微型脉冲喷气发动机的控制以及半主动导引头信号等的特征,设计了基于AVR单片机的控制电路,该控制电路具有控制6个发动机的能力,同时具有对导引头目标信号处理、弹道控制、实现发动机控制策略等的能力,以及即时串口输出控制电路工作参数。通过对控制电路的测试,控制电路较好的实现了控制微型脉冲喷气发动机的功能,具有运用在单兵火箭弹道修正的可行性。更多还原

【Abstract】 Accurate strike has been a main character of modern warfare. Endue conventional ammunition with accurately strike ability is the trend of ammunition development, and trajectory correction is an effective means. In this dissertation, we focus the work on the execute mechanism of the trajectory correction rocket grenade, which is one of the key technology. A new type of trajectory correction execute mechanism - micro impulse jet engine - was put forward that is used in the infantry rocket grenade. A control circuit was designed for calculating and controlling the trajectory of the rocket grenade according to the working characteristics of the micro impulse jet engine and semi-active laser guider.The working principle of the correcting micro impulse jet engine was expatiated, and a prototype was worked out. The result of thrust test showed that the thrust value reached 1.425N while the compressed air pressure of engine was 0.65MPa. AVR single chip processor was applied in the control circuits which integrates the functions of target signal processing from the guider, 6 jet engines controlling, trajectory calculating and parameter outputting by serial port. Test showed that it could carry out the correcting control function according to the trajectory information from the guider head, and the trajectory correction execute mechanism is feasible for infantry rocket grenade.更多还原
