为获得激光陀螺在未来系统要求的精度、尺寸和环境等条件下运用,霍尼韦尔公司已做过验证试验。本文重点论述再入系统的一些技术问题,因为再入系统是目前急需的一项运用工程。全文介绍四个基本内容:飞行器中惯性测量装置(IMU)的定向,装置的轻小型化,激光陀螺的选择,以及IMU和处理器可能的组合方式。IMU定向是经过分析各种安装方案及其误差特性后选取的安装方式。激光陀螺的选择是在研究不同陀螺性能、尺寸和重量等所能达到系统精度的基础上进行的.IMU和处理器的组合方式是通过分析整个制导和控制系统的处理数据需要(飞行器中的处理存储单元)来确定的。系统方案研究结果表明,为满足性能、尺寸要求,需要一种新尺寸激光陀螺,用这种陀螺(GG1320)构成的新型再入制导和控制系统方能满足当前和未来再入系统的要求。
Honeywell has validated the laser gyro for use in future systems requiring accuracy, size, and environment. This article focuses on some of the technical aspects of reintroducing the system, as re-entry is an urgently needed application. The full text describes four basic elements: the orientation of the inertial measurement device (IMU) in the aircraft, the miniaturization of the device, the selection of the laser gyro, and possible combinations of IMUs and processors. IMU orientation is selected after installation by analyzing various installation scenarios and their error characteristics. The choice of the laser gyro is based on the study of the gyro’s performance, size and weight, etc. The combination of the IMU and the processor is accomplished by analyzing the processing data needs of the entire guidance and control system (processing in the aircraft Storage unit) to determine. The results of system research show that in order to meet the requirements of performance and size, a new size laser gyro is needed. The new reentry guidance and control system composed of this gyro (GG1320) can meet the requirements of current and future reentry systems.
