AI Technical Summary

Technical Problem

Existing air data systems on aircraft are vulnerable to failures due to icing and foreign object ingress, which can lead to inaccurate flight guidance and safety risks, despite redundancy measures, as probes can become malfunctioning or damaged before takeoff.

Method used

A probe that can be moved from inside to outside the aircraft during flight, allowing for immediate replacement or protection from adverse environmental conditions, ensuring continuous safe operation by maintaining controlled environmental conditions and preventing icing, and can be designed as a Pitot probe to measure total and static pressures.

Benefits of technology

Enables safe flight continuation by providing accurate air data parameters and reducing the risk of probe malfunctions due to icing or foreign object entry, enhancing flight safety by providing an additional redundancy level and allowing for iterative operation to maintain reliable flight guidance.

Abstract

The invention relates to a sensor for an aircraft (2) for measuring at least one state or pressure value of an air volume (V) surrounding the exterior (3) of the aircraft (2) in order to describe at least one operating parameter of the aircraft (2). The aim of the invention is to provide a sensor for an aircraft for measuring pressure values of an air volume surrounding the exterior of the aircraft, said sensor allowing a reliable function of the flight guidance even under very adverse surrounding conditions of the aircraft. This is achieved in that the sensor (1, 1') is made so as to be movable from the interior (4) of the aircraft (2) to the exterior (3) of the aircraft (2) at least during a flight of the aircraft (2).
