“Gloria” Passes Acceleration Test in the Centrifuge

The GLORIA instrument (Gimballed Limb Observer for Radiance Imaging of the Atmosphere) is a joint project of Forschungszentrum Jülich and Karlsruhe Institute of Technology. The aim is to provide a detailed global image of the tropopause region, which plays an important role in the climate system of the Earth.
GLORIA will be used on the research aircraft Geophysica and HALO.
The instrument holder designed and fabricated by ZAT will bear the interferometer (Michelson Fourier spectrometer). The gimballed structure of the instrument holder keeps the instrument level when the aircraft moves, so that a steady point can be observed at a distance of 250 km, with an error of  ±50 m.

As part of the airworthiness certification process, aircraft operators must demonstrate sufficient strength of all components. The specified load conditions may actually occur in extreme flight situations. All components have therefore been designed in such a way that even in these special cases, no  plastic deformation will occur and the functionality of GLORIA will therefore be maintained.

In order to provide proof of GLORIA's suitability, the instrument was exposed to an acceleration seven times higher than the acceleration due to gravity in the ZI centrifuge at Ruhr-Universität Bochum.

GLORIA successfully passed all six load tests in the presence of official representatives of the aircraft operator and was subsequently demonstrated to be fully operational.
