摘要： A complete, computer based, vehicle management system (VMS) for X-Wing aircraft using digital "fly-by-wire" technology controlling many subsystems and providing functions beyond the classical aircraft flight control system. The vehicle management system receives input signals from a multiplicity of sensors and provides commands to a large number of actuators controlling many subsystems. The VMS includes--segregating flight critical and mission critical factors and providing a greater level of back-up or redundancy for the former; centralizing the computation of functions utilized by several subsystems (e.g. air data, rotor speed, etc.); integrating the control of the flight control functions, the compressor control, the rotor conversion control, vibration alleviation by higher harmonic control, engine power anticipation and self-test, all in the same flight control computer (FCC) hardware units. The VMS uses equivalent redundancy techniques to attain quadruple equivalency levels; includes alternate modes of operation and recovery means to back-up any functions which fail; and uses back-up control software for software redundancy.

摘要： In an X-Wing aircraft a dynamic higher harmonic control (HHC) system addresses the vibration which typifies a very rigid rotor and is implemented in two ways--a scheduled HHC and an active HHC. A scheduled HHC is located within the quadruple redundant portion of the flight control computers (FCC). This includes look-up maps for the second through fifth harmonic coefficients of the control equation as a function of airspeed and lift for rotary wing (RW) operation, and as a function of rotor speed for conversion (CV) operation. These are added to the collective and cyclic terms of the control equation and implemented through the pneumatic control valve (PCV) actuators. This flight critical portion of the HHC maintains vibration loads within structural limits. An active HHC, implemented in a dual redundant configuration, is added primarily to enhance vibration control during maneuver conditions and during conversions. It monitors vibrations at selected locations and in selected axes of the vehicle and generates corrective factors, which are added to the scheduled coefficients. The active HHC, representing a significant computational burden, is implemented in a separate dual processor computer section, complete with its own input/output signal processing.
摘要翻译：在X-Wing飞机中，动态高次谐波控制（HHC）系统解决了代表非常刚性转子的振动，并以两种方式实现 - 一种预定的HHC和一个主动HHC。预定的HHC位于飞行控制计算机（FCC）的四重冗余部分内。这包括作为旋转翼（RW）操作的空速和升力的函数的控制方程的第二到第五谐波系数的查找图，以及用于转换（CV）操作的转子速度的函数。这些被添加到控制方程的集合和循环项，并通过气动控制阀（PCV）执行器实现。 HHC的该飞行关键部分在结构限制内保持振动负载。增加了以双重冗余配置实现的主动HHC，主要用于在机动条件和转换期间增强振动控制。它监视选定位置和车辆选定轴线的振动，并产生校正因子，这些因子被加到计划的系数中。代表重大计算负担的主动HHC在独立的双处理器计算机部分中实现，具有自己的输入/输出信号处理。
