Fatigue tests for Major Airframes and Components of Aircrafts

• Conception, Performance of fatigue test on complete airframes, subsystems and components
• Development of test concepts (loading, control and data acquisition systems, restrain system, etc.)
• Determination of service life
• Investigations into damage tolerance characteristics, crack propagation and residual strength
• Test planning, engineering and set up
• Design, manufacturing, installation of test rig; load introduction systems (pads, fittings, whiffle trees); dummies (e.g. engine, landing gear, flap track, pylon)
• Simulation by FE- and system simulation models
• Development of loading programs
• Management of transportation of test structures to the test site
• Integration of the test specimen into the test set up
• Development and design and installation of hydraulic loading system
• Development and design and installation of pneumatic loading system (for fuselage pressurisation, fuel tank pressurisation, etc.)
• Development and installation of control and monitoring system (high test speed!)
• Development and installation of data acquisition system
• Configuration and installation of measurement sensors (strain gages, deflection transducer, thermo couples, etc.)
• Performance of static measurements, evaluation of results
• Performance of test structure inspection, damage investigation
• Documentation of all test results
