LMS and Alva complete GVT project

A LMS International product story
Edited by the Engineeringtalk editorial team Mar 10, 2009

LMS and its Spanish partner, Alava Ingenieros, have completed a GVT technology project with the ground vibration testing team at EADS-CASA.

Part of an on-site support project, LMS and Alava Ingenieros engineers helped with the EADS-CASA deployment of a 700-channel LMS SCADAS III hardware and LMS Test.Lab software system over a series of three GVT tests: the Airbus A310 MRT, the Airbus A330 MRTT and the Airbus A400M.

The project covered complete LMS Test.Lab and LMS SCADAS III system installation and integration, extensive training and on-site assistance.

'The A400M test shows that all kinds of GVT requirements can be accomplished with this equipment - even the largest aircrafts,' said Mr Posada, head of structural test, EADS-CASA MTAD.

'In addition, we realised a considerable productivity increase and cut the overall acquisition time in half.' Beginning 26 September 2008 at the FAL's Flight Test Centre in Seville, Spain, the entire GVT cycle took just under a month.

During this period, various GVT tests, performed by a joint team from EADS-CASA MTAD's structural test department in collaboration with EADS-CASA MTAD's aeroelasticity and dynamic loads department, were carried out on the first aircraft, the Airbus A400M MSN01, which was placed on an elastic rubber platform to simulate a 'ready for flight' configuration.

These standard tests measured the frequency and damping modal parameters to determine the aircraft's dynamic behaviour from an aeroelastic point of view.

'The commitment from the LMS and Alava Ingenieros experts regarding the test objectives was outstanding,' said Hector Climent, head of aeroelasticity and dynamic loads, EADS-CASA MTAD.

'This ranged from the test coordination to the way they helped the team quickly resolve unexpected test and aircraft system problems.

'The GVT usually takes place very close to the first schedule flight and there is no room for failure or delay.

'Saving a couple of weeks is a rather exceptional achievement for this kind of mission critical test,' he added.
