Modular and Integrated Digital Probe for SAT Aircraft Air Data System
The main objective of the MIDAS project is to design and manufacture a smart and fully integrated air data probe (ADP) for SAT applications, characterized by the following features:
- reduced size and weight;
- reduced power consumption;
- improved reliability;
- fully-integrated with the onboard communication bus;
- fault tolerant, thanks to the health monitoring functionalities.
The ADP will be delivered after:
- a thorough test campaign for verification and validation of the manufactured system;
- environmental requirement verification (Temperature, Vibration, Icing, EMI/EMC).
Quality is ensured by the documented traceability of measurement results.
In order to achieve these targets, the solution will include key enabling innovative technologies such as:
- single Line-Replaceable Unit (LRU) with the capability of communicating with other FBW control system devices through a standard legacy (e.g. Arinc429, CanBUS Arinc825) and innovative communication bus (e.g. AFDX). As a further step it may be evaluated the introduction of a AFDX over fibre link channel to furtherly drastically reduce wiring weight on the aircraft, signals crosstalk and susceptibility and to increase the overall system reliability;
- optimized fail-safe architecture;
- innovative air data strategies to implement virtual sensors with the aim to reduce the use of physical probes;
- redundant power supply and advanced health monitoring (hardware and software) based on previous partners’ experience exploiting power-up, initial and continuous built-in test;
- advanced air data algorithms focused on air data system optimization, based on partners’ previous experience;
- anti-ice capability using automatic heater in order to avoid holes occlusion due to ice formation;
- complete sensors characterisation, calibration and target uncertainty evaluation.
