Abstract: An air data system includes pitot pressure probes with sensing ports, anti-icing electric heaters, conduits, pressure transducers, outer air temperature sensors, and a computer incorporated in a single streamlined housing attached to the aircraft and composed of axisymmetric surfaces. The system is autonomous and interacts with the aircraft and its subsystems through only the information exchange channels and power supply lines via electric connectors. The housing also incorporates electric adapters and the system includes pitot pressure probes which are faceted pins protruding from the housing having sensing ports between edges. The housing surface or its part can be made of hydrophobic materials. The system can include a set of independent subsystems wherein the units and components are housed in individual streamlined housings attached to aircraft components. The subsystems are autonomous and interact with the aircraft and the other subsystems through the information exchange and power supply lines only.

Abstract: The present invention relates to aviation. The proposed air data system includes pitot pressure probes with sensing ports, anti-icing electric heaters, conduits, pressure transducers, outer air temperature sensors, and computer; the above units and components are incorporated in a single streamlined housing attached to the aircraft and composed of axisymmetric surfaces. The system for air data acquisition is autonomous and interacts with the aircraft and its subsystems through only the information exchange channels and power supply lines via electric connectors. To make the system more autonomous, its housing also incorporates electric adapters. To expand the measurement range, to save structural weight and diminish the necessary number of pressure measurement channels, the system includes pitot pressure probes which are the faceted pins protruding from the housing and having the sensing ports between edges.
