Project description
Reliable Virtual Test validation technologies to enhance aircraft safety and performance
Aircraft Certification is time-consuming and expensive. A reliable methodology based on partially replacing the required laboratory tests by virtual ones can tremendously enhance aerospace competitiveness and consumer safety through the evaluation of numerous scenarios; some potentially dangerous. Virtual Tests are based on mathematical models that must be reliable. It is necessary to validate them, by means of an experimental test campaign, to ensure its predictability. TABASCO project expects to improve this validation by assessing advanced metrological tools such as Digital Image Correlation, Acoustic Camera, Thermography and wireless strain gauges. This advanced instrumentation will allow obtaining scientifically relevant data to sustain model validation. In addition, the project will evaluate new IT solutions developed by Applus to strength the validation methodology. TABASCO consortium plans to support aeronautical industry to create better structural models allowing time and cost reduction through Virtual Testing focusing on the Clean Sky LPA Advanced Rear Fuselage structure.
Objective
The work of this consortium will be the experimental verification by means of a test campaign (Level 2-3) of a novel design, material, structural an industrial process for the Advanced Rear End (ARE) demonstrator included in WP1.2 on Platform 1 of Cleansky project.
This project has three research objectives:
1) Implement new methodologies to support, validate and correlate Virtual Testing Models.
2) Design and manufacture innovative tool and test setups to maximize the instrumented area to better identify the boundary conditions of the test based on Absolute Accurate Methodology.
3) Research advanced instrumentation solutions to improve quality of the results reducing cost and time in future aircraft certification test campaigns.
To achieve these objectives, the following IT tools, methodologies and novel instrumentation will be researched:
a. Applus E-Testing© monitoring service to follow up the metrological data in real-time using a simple internet browser. This technology allows correlating real-time video recording and measured data (load, stress…) with FEM predictions.
b. CAETest Bench for accurate representations of material behaviour.
c. Thiot CESAR© software to simulate gas gun performance to reduce the initial test trials to adjust the pressure and other launcher parameters.
d. Applus Absolute Accurate Methodology
e. Faster and more accurate optical Full Field stress measurement based on Match ID Technology that allows improving Digital Image Correlation uncertainty and advanced algorithms to allow measurements in Real- time during the test.
f. Innovative methods to improve crack/de-bonding onset and propagation detection by:
i. Acoustic Camera contactless metrology from GFAI TECH GmbH to quickly hot-spot de-bonding and first Failure cracks
ii. Structural Health Monitoring to control the damages of the structures being tested with the support of Universidad Politécnica de Madrid
g. Improved wireless Strain gauges taking advantage of Applus IoT Lab capacities to reduce the test setups time and complexity and allow Structural Monitoring of the tested part.
h. Residual Energy “live” sensor based on instrumented projectile catchers developed by Thiot
