In the AMTRAS Project there are two well differentiated areas of development: the first one for AIRBUS DEFENSE AND SPACE; and the second one for AIRBUS HELICOPTERS.

In the first part of the project, the aim is to develop a series of adaptive test rigs, that would fit the testing necessities of the different development stages of multipanel aircraft components for AIRBUS DEFENSE AND SPACE.

In the second stage of the project, AIMEN has developed a test rig for the tail unit of a new rotorless tail helicopter, in collaboration with third parties such as CTA, AERNNOVA and AIRBUS HELICOPTERS.


Three different adaptive test rigs in order to cover the development stages of the multipanel component to be tested: Stringer Crippling, Stringer RunOut and Stringer Subcomponent. Each stage of development studies a different part of the final product, so a new test rig is needed in for each scenario, due to the differences in dimension and shape, but they also need to be adaptive and able to be set up easily, in order to fit the variations in the manufacturing of each specimen.

Stringer crippling

Design basis:

A FEM model has been developed in order to assure a security ratio between the resistance of the test rig and the maximum load applied.

Stringer runout

In the second stage of the component development, the specimen has increased in dimensions and also in complexity, so the challenge in the design became bigger with the specimen

Design basis:

Stringer subcomponent

In the last stage of the component development, the challenge was similar to the Stringer RunOut scenario, with a larger specimen and a more complex shape. The fixture to the test rig needed to be revised, as well as the anti-deflection structure.
