When I started this B-2 book project back in November 1988, I wasn’t quite sure where it would take me or how long the journey would be. My goal was to put something down in print that would show the world just how innovative the American aerospace industry is when they put their collective heads together to create Jack Northrop’s dream come true, the B-2A Spirit Stealth Bomber.I figured that I would be hindered by the very same mindset that surrounded the original Blackbird program: Cygnus to Senior Crown. The Blackbird’s unofficial/official policy toward the release of photos and information back in the late 1960s, through the end of the program in 1990, was not to cooperate, drag their feet on my FOIA requests, and just make life as difficult as they could in my questfor information.
《固体波动陀螺理论与技术》总结了作者在固体波动陀螺领域多年的研制经验,介绍了该类型仪表的理论和技术发展现状,旨在为工程研发人员提供实质性的指导与帮助。
固体波动陀螺的制造特点是必须采用一整套的工艺技术,包括石英玻璃的机械加工和化学处理,仪表精密装配和真空处理技术,以及陀螺特性指标的特有检测方法等。同时需要特殊研发固体波动陀螺的电子线路、控制算法及信号处理方法。在探讨这一系列问题时,作者力图向读者提供解决上述问题的明确途径。
全书分为四章。第1章介绍了固体波动陀螺的基础理论,包括仪表误差的数学模型。第2章研究了固体波动陀螺(半球谐振陀螺)的主要部件——半球谐振子的设计与制造方法。第3章讨论了固体波动陀螺的结构、装配及真空处理方法。第4章阐述了固体波动陀螺电子控制线路的设计原则,并探讨了信号处理及陀螺可靠性问题。
本书从对无人机的认识到各电子元件的应用,从结构件的设计到机械加工,再从固件程序的写入到无人机的试飞,涵盖了多旋翼无人机设计与制作的所有内容。
本书从顶层设计到实践探索,以中国民航局无人驾驶航空器空管信息服务系统(UTMISS)试点为案例来呈现我们思考和演绎民用无人机运行管理的全过程。
