An air data sensing probe or MFP includes a barrel having multiple pressure sensing ports for sensing multiple pressures. Instrumentation coupled to the pressure sensing ports provides electrical signals related to the multiple pressures. A neural network, coupled to the instrumentation, receives as inputs the electrical signals related to the multiple pressures, and in response, the neural network provides, as an output, electrical signals indicative of at least one local air data parameter for the air data sensing probe.

Multi-function air data probes employing neural networks for determining local air data parameters

A system for determining physical characteristics of an incident flow stream over a surface of a vehicle includes a plurality of acoustic sensors mounted to the surface and configured to sense pressure fluctuations caused by the incident flow stream. The plurality of acoustic sensors provide output signals indicative of the sensed pressure fluctuations. Processing circuitry coupled to the plurality of acoustic sensors, measures flow velocity in a first direction as a function of the output signals of at least two of the plurality of acoustic sensors, and measures flow velocity in a second direction as a function of the output signals of at least two of the plurality of acoustic sensors. The processing circuitry is configured to calculate an angular direction of flow as a function of the first and second measured flow velocities.
