Abstract: The present invention discloses a rotor control system where rapid changes in rotor torque are transferred into moment forces acting about the blade pitch axis of a rotor blade in a thrust-generating rotor, to ultimately control the movements of a rotary wing aircraft. The moment forces acting on the rotor blade are transferred through a carefully adjusted damping member in order to allow rapid changes in rotor torque to create cyclic changes in blade pitch angle, while slow or permanent changes are cancelled out and affects the rotational speed and the thrust generated by the rotor, without permanently affecting the blade pitch angle of individual rotor blades.

Abstract: A method and device for precise control of and controller design for aircrafts consisting of at least one spinning part and at least one non spinning part is provided. The required torques for control of the spinning parts and for the non-spinning parts are continuously and individually calculated. All torques are combined to get the correct torque for the complete aircraft. Doing this, it's possible to continuously apply the correct torque, both correctly distributed among the roll and pitch axes (correct angle), and correct magnitude. The result is a decoupling of the roll and pitch axes, simplifying controller design to a design of two single input single output controllers, one for each axe.
Abstract translation: 提供了由至少一个纺纱部分和至少一个非纺纱部分组成的用于飞机的精确控制和控制器设计的方法和装置。 用于控制纺纱部件和非纺纱部件的所需扭矩是连续和单独计算的。 所有扭矩相结合，以获得整个飞机的正确扭矩。 做到这一点，可以连续地应用正确分配在滚动轴和俯仰轴之间的正确扭矩（正确的角度），并确定大小。 结果是滚动和俯仰轴的解耦，简化了控制器设计到两个单输入单输出控制器的设计，每个轴一个。

Abstract: Local wind fields can be predicted if both the airspeed and the ground speed of the helicopter are known. An aircraft that uses an inertial navigation unit, autopilot and estimator allows a measure of ground speed to be known with good certainty. The embodiments herein extends this system to allow an estimate of the local wind field to be found without actively using an airspeed sensor, but instead combining the measurements of an accelerometer and a drag force model and a model of controlled aerodynamics of the aircraft to estimate the airspeed, which again can be used to estimate the local wind speed.
