Embodiment Construction

[0010] As described herein, an example air data system architecture includes an air data computer (ADC) co-located with at least one pressure sensing probe. The ADC includes a single pneumatic connection to a port of a pressure sensing probe, such as a total pressure port or a static pressure port, and electrically couples the ADC to one or more other air data probes (e.g., pitot tube pressure probes, static pressure probes, Multiple other connections for total air temperature (TAT) sensor, angle of sideslip (AOS) sensor, and angle of attack (AOA) sensor). Therefore, this example air data system architecture eliminates the pneumatic connections between the ADC and all but one air data probe, thereby reducing the cost, maintenance, and complexity of the air data system. Additionally, a single pneumatic connection allows the ADC to be co-located with one of the pressure-sensing probes without the need for a multi-function probe (MFP) with integrated electronics, reducing air dat...

Abstract

A system includes an air data computer (ADC) having a single pneumatic port for receiving a pneumatic input, a plurality of electrical inputs for receiving one or more electrical signals, and an output. The ADC can transmit, via the output, air data parameters based on the received pneumatic input and the received one or more electrical signals. In a further example embodiment, the system includesa first pressure sensing probe discrete from the ADC and a pneumatic connection joining a pressure sensing port of the first probe to the pneumatic input of the ADC. Second and third pressure sensingprobes pneumatically coupled to respective pressure modules, which output electrical signals to the ADC, the electrical signals being representative of pressures sensed by the second and third pressure sensing probes, respectively.

Description

Background technique [0001] The present disclosure relates generally to air data systems, and more particularly, to air data systems that utilize multiple input air data computers to improve the technical performance of traditional air data systems and reduce the cost and complexity of fully integrated air data systems. [0002] Modern aircraft typically include an air data system that calculates an air data output based on measured parameters collected from various sensors positioned around the aircraft. For example, many air data systems utilize air data probes that measure the air pressure of the oncoming airflow around the exterior of the aircraft to produce aircraft air data outputs such as angle of attack (i.e., the oncoming airflow or relative The angle between the wind and an aircraft reference line (such as the chord of an aircraft wing), calibrated airspeed, Mach number, altitude, or other atmospheric data parameters. Compensate for various local (local to the probe...
