Microbiological Degradation of Asymmetric Dimethylhydrazine, a Toxic Rocket Fuel Ingredient
      
The possibility of microbiological cleaning of water and soil polluted with asymmetric dimethylhydrazine (ADMH), a highly toxic ingredient of rocket fuel (IRF), was studied.
      
Consideration was given to the controlled solid bodies such as aircraft, rocket, and so on moving in the aerodynamic medium.

This paper deals with the yaw channel guidance of the launch vehicle in detail by means of the idea of predictive guidance. The basic principle of perturbative and predictive guidance are described. Under the conditions of both navigation computation and perturbative measurement the basic calculative formula of the perturbative and predictive guidance is derived and the simplified form of the predictive guidance and its requirements for the simplification are discussed. Besides, we also suggest the concept...

This paper deals with the yaw channel guidance of the launch vehicle in detail by means of the idea of predictive guidance. The basic principle of perturbative and predictive guidance are described. Under the conditions of both navigation computation and perturbative measurement the basic calculative formula of the perturbative and predictive guidance is derived and the simplified form of the predictive guidance and its requirements for the simplification are discussed. Besides, we also suggest the concept of "zero control and unbias states" and the problem of optimal control guiding to the zero control and unbias states. A closeloop solution of optimal control was derived. The concept and results are to be researched further.

本文用预测制导的思想,具体研究运载火箭偏航通道的制导问题。阐述了摄动预测制导的基本原理,在有导航计算和有干扰测量两种情况下,推导了摄动预测制导的基本计算公式,研究了预测制导的简化形式以及简化条件。另外,本文还提出了预测制导的“零控无偏状态”的概念,以及向零控无偏状态导引的最优控制问题,推导了最优控制的闭合解。这些概念和结果有待进一步研究,仅供有关同志参考。

The telemetry system presented can work with satisfactory stability and reliability under unfavourable conditions of over 20, 000 g high acceleration and 23, 000 rpm roll rate. Ballistic parameters of the rockets and projectiles and working parameters of their inner components can be measured with the system, which can also be used to measure the parameters of other rolling instruments and devices under high centrifugal conditions. Subassemblies such as high-strength telemetric transmitter with high frequency...

The telemetry system presented can work with satisfactory stability and reliability under unfavourable conditions of over 20, 000 g high acceleration and 23, 000 rpm roll rate. Ballistic parameters of the rockets and projectiles and working parameters of their inner components can be measured with the system, which can also be used to measure the parameters of other rolling instruments and devices under high centrifugal conditions. Subassemblies such as high-strength telemetric transmitter with high frequency plastic packing, thick film integrated subcarrier oscillator with high frequency stability, in-flight calibrator, automatic tuning receiver with fast signal capture and demodulator with extremely short transient state are described. Practical applications and experimental examples are also discussed.

本文介绍的高加速度无线电遥测系统在承受20,000 Gal以上直线加速度及23,000 rpm~(-1)以上高速旋转的恶劣环境条件下可以稳定可靠地工作。它可用于火箭、炮弹的弹道参数及其内部部件工作参数的测量,也可以用于其他高速离心工作状态下的各种设备及器件的测量。文章详述了高强度的遥测发射机及高频塑封技术、采用厚膜集成技术的高频率稳定度的副载频振荡器、飞行校准器等部件,还介绍了快速捕捉信号的自动调谐接收机、过渡过程极短的解调器,最后,给出了此系统实际应用及实验实例。

A new type of laser holographic vacuum stressing nondestructive testing instrument has been developed by the authors. The instrument can be used for testing comparatively large sized samples with most of its optical elements contained inside its airtight cabin. In this paper, the testing results of debond flaws for solid fuel propellant grains are given.The virtues and defects of thermal stressing and vacuum stressing are discussed.
