Descripción del proyecto
Una novedosa sonda digital multifuncional controlará mejor los datos del aire atmosférico
El mantenimiento de las aeronaves en pista se basa en una gran cantidad de tecnologías que incluyen sondas de datos aéreos que miden parámetros como la presión estática del aire, la presión total del aire, el ángulo de ataque, el ángulo de deslizamiento lateral y la temperatura total del aire. En el procedimiento tradicional, esta información procede de múltiples sensores que sobresalen de la aeronave, por lo que dependen de condiciones adversas como el hielo, el polvo y las aves. El equipo del proyecto MIDAS, financiado con fondos europeos, está desarrollando un sistema de datos aéreos multifuncional, modular, integrado y digital que incorpora técnicas de redes neuronales que permiten la estimación del ángulo aerodinámico y la capacidad antihielo. El nuevo sistema se caracterizará por su menor tamaño y peso, su menor consumo de energía y su mayor fiabilidad.
Objetivo
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, initiatial 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.
