Gantner Instruments Provides Measurement Technology Solutions for Aerospace Testing

June 2019, MARIETTA, GA ~ Gantner Instruments has delivered measurement systems for many years to the aerospace industry. The scope of applications ranges from the testing of turboprop equipment for helicopters and aircraft through outdoor testing of jet turbines for large aircraft with more than 1,000 measuring points, primarily for temperature measurement.

For testing the strength of individual components and complete assemblies, Gantner offers data acquisition systems for strain and force measurement, as well as components for controlling and monitoring actuators.

Compliance with all quality criteria is of utmost importance in aircraft assembly. Due to the dimensions, the tolerances are proportionately much smaller than in other industries. For example, the assembly of an aircraft fuselage necessitates work of the highest precision, as our case study at Airbus shows.

During the assembly of delivered fuselage components, the precise alignment of each segment is a prerequisite for high safety, the operational life of the aircraft, and optimum fuel consumption. This alignment is carried out using optical methods. Besides essential orientation, each connection must also be free of material stress. To test this, strain, force and torsion data are acquired at up to 100 measuring points. The quality objective can only be achieved when all components are connected in a stress-free state.

Besides focusing on product quality, Gantner Instruments’ customers from the aerospace industry place special emphasis on the quality of methods and processes in the total enterprise. This covers everything from development, procurement of materials, manufacturing and calibration through to the delivery process. Gantner passes these quality assurance checks and all FATs (Factory Acceptance Tests) and continue to excel in precision, high-speed, durable data acquisition required by the aerospace manufacturers around the world.
