Obiettivo del progetto (Objective)
'A fluidic sensor system for the reliable detection of flow separation at low speed will be developed, manufactured and tested in view of flight application. It will comprise an optimized combination of fluidic micro sensors as well as a multichannel measurement system including sensor control and calibration as well as data acquisition and communication electronics. Starting from different types of fluidic micro sensors and combinations thereof, the sensor system development will be performed with the aim to provide a robust and reliable measurement tool for flow control operations in view of flight tests. Ability for flush mounting and easy integration is essential for the sensor front end. The readout electronics should be designed for minimum space and low power consumption. The whole sensor system will be examined in view of reducing complexity and will be integrated and tested in preparation of a large scale wind tunnel test and in view of flight. Such a sensor system is expected to be the basis for monitoring and validation of the function of open loop separation control systems and at a later stage the essential control input for future closed loop flow control systems in high lift applications. These will provide a new potential for fuel saving, noise reduction and safety.'
Introduzione (Teaser)
Researchers have developed a microfluidic sensor system to control aeroplane wing-flaps more precisely. The work contributes to a greater European strategy for lowering the environmental impact of aircraft.
Descrizione progetto (Article)
It is envisioned that by 2020, aircraft should have significantly reduced fuel costs and increased overall efficiency. Improved microfluidics control would enable shorter take-off and landing distances, thereby reducing associated costs and noise pollution.
The EU-funded 'Flow sensor system for the separation detection at low speed in view of flight' (FLOWSENSYS) project aimed to build a sensor system to monitor flow separation at low speeds. This would allow for closed-loop active flow control (AFC) of trailing edge flaps.
The project first reviewed the available sensor technologies for this application to narrow the choice of sensor. In parallel, a sensor layout was developed as the backbone of a sensor array that could be installed into new aircraft.
Next, several sensors were tested with and without flow separation to compare their sensitivity. The most promising sensors were selected for further testing in a wind tunnel. A realistic (swept and tapered) wing model was built to test the sensors in relevant conditions.
The FLOWSENSYS project eventually showed that the Airbus micro-dot surface hot film sensors could accurately detect the state of flow in a microfluidics system. That sensor system is now available to be incorporated into larger European aeronautics research projects.
