The new DLR short-arm centrifuge in :envihab

The new short-arm human centrifuge was installed in :envihab at DLR Cologne between late February and early March 2013. Installation of the 'heart of :envihab' lasted several weeks. We took advantage of this rare opportunity to take a closer look at the individual stages of the installation (with time-lapse video).

Installation of the short-arm centrifuge

The centrifuge hall has been prepared so that the articulated lorry bearing the separate components of the short arm centrifuge can access it directly.

The pedestal has to be lowered into place using a cable hoist due to the difference in height between the centrifuge hall and the corridor.

The site for the pedestal is prepared in the centre of the hall. Specialists from Austrian manufacturer AMST are in charge of the installation work.

Bolts are used to firmly attach the pedestal to the foundation, a floating concrete slab. The centrifuge's water-cooled motor is located inside the base.

The assembly table is built around the pedestal. This construction will be secured to the raised floor.

The main arm of the centrifuge is brought into the hall. A cover protects the integrated electronics and mechanisms against dust and prevents damage during transportation.

The main arm – 7.4 metres long in total – is in position in the hall, completely filling the picture. The centrifuge can generate forces of up to six times the force of gravity at the ends of the arm.

The three-metre side arm is attached to the main arm of the centrifuge. Designing the main motor as a torque motor enables the smooth operation of the centrifuge.

The protective cover is removed from the research instruments so all the necessary cable connections can be assembled.

Installation of the 'heart of :envihab' is complete. Initial tests will take place following the opening of :envihab on 5 July 2013.
