Embodiment Construction

[0015] Example methods and apparatus disclosed herein sense or detect aircraft surface deformations. In addition to detecting surface deformations, example methods and apparatus disclosed herein determine whether aircraft operating condition(s) and / or flight environment conditions affect aircraft performance based on detected surface deformations. More specifically, example methods and apparatus disclosed herein analyze information based on one or more parameters (e.g., one or more surface deformation characteristics, environmental data, aircraft state or operating parameters, etc.) Grading is performed to determine the likelihood that the detected surface deformation will affect the performance or safety of the aircraft. Accordingly, the example methods and apparatus disclosed herein significantly improve the quality and / or accuracy of detected aerodynamic and / or propulsion system surface conditions based on environmental conditions, thereby enabling pilots to determine wheth...

Abstract

Methods and apparatus for detecting surface deformation of aircraft surfaces (104) are disclosed. An example apparatus includes a sensor system to monitor an aircraft surface (104), the sensor systemincluding a first sensor (116) and a second sensor (118). A surface monitoring system (102) receives signals from the first sensor (116) and the second sensor (118) and based on the signals received,the surface monitoring system (102) is to: detect a surface deformation on the aircraft surface (104); analyze one or more environmental conditions or aircraft parameters; and classify a severity of adetected surface deformation based on the one or more environmental conditions or aircraft parameters to determine if the detected surface deformation impacts aircraft performance or safety.

Description

technical field [0001] The present disclosure relates generally to aircraft, and more particularly, to methods and apparatus for detecting deformation of aircraft surfaces. Background technique [0002] Generally, aircraft surfaces are prone to deformation during flight. Surface deformation of an aircraft surface may affect or alter one or more aerodynamic properties, which may degrade aircraft performance. For example, deformation of aircraft surfaces may affect (eg, reduce) lift, engine efficiency, etc., and / or may cause compressor stall or engine stall. For example, a vertical short take-off and landing (V / STOL) aircraft is an aircraft that can take off, land and / or hover vertically and can transition from a vertical hover mode to a horizontal flight mode. In some cases, when hovering over certain ground materials and in combination with certain atmospheric conditions (e.g., wet sand, containing moisture), the aerodynamic surfaces or inlets of such vehicles may be expos...
