  • Patent number: 12234010
    Abstract: A wind estimation system for an aircraft includes a first sensor configured to sense a first position associated with an aircraft control component in a wind condition, a second sensor configured to sense a first configuration associated with a rotor system of the aircraft in the wind condition, and at least one controller in communication with at least one of the first sensor or the second sensor. The at least one controller is configured to determine a tip-path-plane angle of the aircraft based on the first position and the first configuration, and determine at least one of a current wind speed or current wind direction based on the tip-path-plane angle.
    Type: Grant

  • Patent number: 12122507
    Abstract: A flight control system for a rotary-wing aircraft includes a shape sensor and a controller. The shape sensor is configured to measure a shape of a rotor blade during movement of the rotor blade. The controller is communicably coupled to the shape sensor and is configured to (i) receive, from the shape sensor, a first signal indicative of a first blade shape; (ii) receive a blade characteristic regarding the rotor blade; and (iii) determine at least one of a moment or force associated with the rotor blade based on the first signal and the blade characteristic.

  • Publication number: 20200090524
    Abstract: According to an aspect, an apparatus is provided. A computing system is provided. A user interface is configured to receive an input from a user related to one or more changes to flight path and transmit the input to an autonomous flight system. The input to the autonomous flight system does not cause the autonomous flight system to disengage.

  • Publication number: 20190227558
    Abstract: A processing system for displaying tasks on a map based on context of the tasks includes a mission decomposition module to decompose a mission into a plurality of tasks; a flight planning module to generate a flight plan. The processing system further includes a display to display the task interface to at least one user. The task interface includes the flight plan overlaid on a map and an indicium associated with at least one of the plurality of tasks. The indicium is positioned along the flight plan based at least in part on when the at least one of the plurality of tasks is to be performed. The processing system further includes a flight control system to execute the at least one of the plurality of tasks.
