Flight control system for rotary aircraft
The patent US12043370B2 outlines a flight control system specifically designed for rotorcraft, which integrates a data structure that correlates flight control inputs with actuator outputs based on the rotorcraft's flight conditions. The system employs circuitry and logic instructions to query this data structure for control input modifiers, such as gain, which are then used to determine the appropriate actuator outputs. These outputs can control various components, including blade positions and tail rotors, ensuring that the rotorcraft responds accurately to pilot inputs under varying flight conditions, such as airspeed and environmental factors.
Additionally, the patent describes the use of tangible, non-transitory computer-readable storage media that contain executable instructions for processing flight control input data and modifying factors. This includes querying an n-dimensional lookup table to derive flight control actuations based on the received data. The system is designed to accommodate inputs from various inceptors, including collective, cyclic, and pedals, and utilizes bucketized gain curves to enhance the precision of actuator control across different flight conditions. The method of electronically controlling the rotorcraft involves translating flight control displacements into actuator displacements, thereby driving the actuators in a manner that optimizes flight performance and safety.
