PROJECT OBJECTIVE

The role of accelerometers in aircraft prototypes

The objective of this project was to supply the necessary vibration sensors for the different Flight Test (FTI) of several aircraft prototypes, in order to validate the structural designs and systems, as well as to support their certification before the authorities.

Airbus Defence and Space carries out rounds of consultation to define the characteristics of the accelerometers best suited to the requirements and particularities of each test, ensuring that they meet the established needs without compromising safety margins.

How we made it happen

ICP triaxial accelerometers

Our offered solution was the contributed supply, since 2017, of 130 triaxial accelerometers with ICP technology for different flight tests performed by Airbus.

These sensors, used to obtain data for subsequent analysis during certification campaigns, must be of the highest precision to ensure that the results received are correct. Accelerometers are used especially for vibration and flutter measurements, both in military and civil applications, monitoring several parameters to help understand aircraft behavior (high vibration, shock or aeroelasticity are some of these parameters).

For use in demanding applications, accelerometers had to accurately measure both low and high frequencies, and operate in extreme conditions such as very low or high temperatures, presence of fuel, high voltage, water, mud or ice. Therefore, these accelerometers had a hermetically sealed titanium housing, withstood overloads of up to 5,000 g, operated between -54°C and 85°C (or higher), and had electrically insulated bases to prevent electrical noise.
