Tests using SoMat eDAQ and strain gauges from HBM
Comprehensive structural and component tests
are always key to the development of a new airplane. This is particularly true for the AKOYA using many composite materials
whose behavior during operation needs to be thoroughly tested.
LISA Airplanes has opted for HBM's ultra-rugged SoMat eDAQlite system
for measurement data acquisition. The fullcompact data acquisition system
is insensitive to vibration
and can be directly installed in the airplane
. SoMat eDAQlite supports LISA Airplanes in gaining more precise insights in the stresses affecting the airplane's structures during the various phases of flight. Multiple eDAQlite DAQ cards and modules (e.g. ELCPU, ELBRG, ELDIO) acquire data from strain gauges
installed on the wings (installed in quarter-, half- and full-brige configuration) and a wide range of other measurement data, for example GPS coordinates. HBM also has supplied the strain gauges.
"The high resolution offered by SoMat eDAQlite allows us to determine how even small waves of less than 10 centimeters affect the airplane landing on the water surface at 110 km/h", explains Laurent Vallet, Head of Development at LISA Airplanes. Safe operation
is crucial and requires extensive testing. However, LISA Airplanes also takes measurements to find ways to increase comfort during the flight. Installed strain gauges provide useful data to make flying more convenient and tranquil for pilots.
