Project Overview
In 2010, Snecma has implemented a comparative benchmarking between BeanAir Wireless acquisition system and a wired acquisition system. BeanAir Wireless measurement system will be integrated into rocket engine’s subsystems and onboard equipments during test sessions.

Project Goals
Long-term main technical aims are:
• Positioning this kind of sensors in a harsh environment and in difficult access areas.
• Simplifying the system thanks to the reduction of quantity engine cables; consequently, engine mass will be reduced as well.
• In the long term, allowing self-diagnosis thanks to microcontrollers and Wireless Sensor network.

Interview with Philippe Nivet, from Snecma group
1) Could you describe your work within Snecma group?
I am a project manager for instrumentation on demonstrators and testing machines, in Research and Technology domain. I identify innovative technologies enabling to develop solutions for applications in ground-based and embedded measurement.
2) What was your need in terms of Wireless Sensors Networks?
Firstly, to demonstrate that wireless transmission is as effective and efficient as the wired one in terms of transfer function and metrological quality; secondly, to allow us to reduce great amount of cables on a machine.
3) What do you think about BeanAir products?
The research and the implementation of the prototype we have developed in cooperation with BeanAir let us demonstrate BeanAir products’ quality and high performance BeanAir has been able to properly answer to our technical needs within the deadline, with a demonstration in laboratory of a successful prototype.
