Real time Optoelectronic Sensors for Electro-Actuator Hydraulic Fluid Contamination Monitoring

Descrizione del progetto

Ispezionare i fluidi idraulici degli aeromobili per la degradazione

Rilevare precocemente i contaminanti nel petrolio potrebbe migliorare la durata di servizio dei componenti idraulici negli aeromobili. Il progetto FluidER, finanziato dall’UE, sta sviluppando un nuovo sensore in linea che dovrebbe assicurare il funzionamento ottimale dell’attuatore elettroidraulico dell’aeromobile attraverso regolari controlli dei fluidi. L’unione di sensori eterogenei contribuirà ad identificare diversi tipi di contaminazione del fluido idraulico, che comprendono cambiamenti nelle proprietà fisicochimiche del fluido (viscosità, densità, umidità, colore o temperatura) o presenza di particolati e infiltrazione idrica. Il nuovo strumento avanzato dovrebbe ridurre l’usura dei componenti idraulici, garantendo la continua pulizia e limpidezza dei fluidi idraulici.

Obiettivo

FluidER project aims to deliver fully integrated and autonomous sensor for in-line sensing and diagnosis of aviation hydraulic fluids (HF) used in electro Hydraulic Actuators (EHA). The proposed diagnosis approach is based on the combination of hydraulic fluid physic-chemic parameter sensors and fluid contamination sensors and, with the aim of achieving an early warning of degradation signs, especially in terms of particulate count and water contamination, before the hydraulic fluids exceeds the service limits.

The combination of a set of heterogeneous sensor technologies is motivated by the lack of accuracy achieved by single devices, especially when dealing with multi-source contaminations and when an early identification of degradation evidences is targeted. FluidER proposal merges two types of approaches: (i) Sensors delivering measurements of physical and chemical parameters of the Hydraulic Fluid as the Viscosity, Density, Moisture, Dielectric Constant, Colour or Temperature, and (ii) sensors specifically designed to monitorize different contamination sources as the particulate matter concentration, presence of air or water.

Specifically, FluidER will address the analysis of physical contaminants (metallic and non-metallic particulate count, air bubbles, etc.) through in-line microscopic imaging and machine vision proprietary techniques. Additionally, chemical contaminants (water content, acidity) will be estimated through VIS-IR spectroscopic inspection and chemometric algorithms.
The information obtained from the different sensors will be used to generate a Diagnosis of the status of both, the fluid itself and the EHA equipment, through new health monitoring algorithms.

The different hardware and software components included in the FluidER solution will be gradually tested in different test beds, ranging from controlled laboratory hydraulic test beds to a complete EHA test bed and different standardized aircraft tests.
