Embodiment Construction

[0024] Aspects disclosed herein provide systems and methods for aircraft buffet detection. The buffeting analyzer receives acceleration sensor data from one or more sensors on the aircraft. For example, the acceleration sensor data includes longitudinal acceleration sensor data and lateral acceleration sensor data associated with time windows. A buffeting analyzer generates a longitudinal buffeting metric for the time window based on the longitudinal acceleration sensor data. The buffeting analyzer generates a lateral buffeting metric for the time window based on the lateral acceleration sensor data. In a particular example, the buffeting analyzer applies weights to the longitudinal acceleration sensor data and the lateral acceleration sensor data to prioritize sensor data associated with frequencies that are more perceptible to humans, and based on the weighted acceleration sensor data determines the longitudinal buffeting metric and Lateral buffeting measurement. The chat...

Abstract

The invention relates to aircraft buffet detection. A device includes one or more processors configured to access sensor data generated during a time window by one or more sensors onboard an aircraft. The one or more processors are configured to determine, based on the sensor data, a lateral acceleration dataset indicating frequency and magnitude of lateral buffet of the aircraft detected during the time window. The one or more processors are configured to determine, based on the sensor data, a vertical acceleration dataset indicating frequency and magnitude of vertical buffet of the aircraft detected during the time window. The one or more processors are configured to determine a buffet metric based on the lateral acceleration dataset and the vertical acceleration dataset. The one or more processors are configured to determine a buffet indicator based, at least in part, on the buffet metric. The one or more processors are configured to provide the buffet indicator to a display.

Description

technical field [0001] The present disclosure generally relates to detecting aircraft buffeting. Background technique [0002] Aircraft buffeting is an indicator that the aircraft is approaching aerodynamic limits, such as stall limits. Traditional buffet quantification methods rely on pilot perception. For example, different pilots may determine buffeting during different phases of the aircraft stall maneuver, since each pilot may have a different tolerance for buffeting. Buffeting can also be determined by the same pilot performing different phases of the maneuver at different times, as the same person's tolerance to buffeting may vary. Subjective determination of chatter can lead to inaccurate chatter detection. Contents of the invention [0003] In a particular implementation, an apparatus for detecting buffeting in an aircraft includes one or more processors configured to access data generated by one or more sensors on the aircraft within a time window sensor data...
