Short Arm Human Centrifuge

The innovative Short Arm Human Centrifuge for space medicine and life science experiments under artificial gravity conditions – designed by AMST for DLR in Cologne @ :envihab


Next generation Short Arm Human Centrifuge designed by AMST for the German Aerospace Centre (DLR) in Cologne


The SAHC called :envifuge at the German Space Centre (DLR) :envihab is equipped with an outstanding scientific platform to investigate the effects of long duration artificial gravity and hyper gravity.

Based on the past experience and on a large number of centrifuge experiments, DLR and AMST have developed a unique research and training device in the field of artificial gravity called :enviFuge. It is a new and innovative research device for future studies on the effects of artificial gravity on the human body.

The system is designed to perform following complex training exercises whilst spinning:

High level of modularity and adaptability in order to meet future needs

Centrifuge Hub

The centrifuge hub consists of three main assembly groups, main arm with rail guides and spindle drives, two secondary arms (detachable) with rail guides and spindle drives, a lattice arm equipped with a robotic- and a motion capturing system.

Centrifuge Lattice Arms

On the main arm, the spindle length is dimensioned that the nacelle can be moved over the centre of rotation. It has two payload bays that can house customer’s specific devices. The lattice arm carries the motion capturing system and a robotic arm. On the secondary arms, it is possible to attach customised nacelles.

Subject Nacelles

There are three different nacelles. The standard nacelle is designed for subjects at lateral or supine position. At the foot end are two tri-axial force plates. Instead of the force plate, a vibration plate can be mounted. Alternatively, to the standard nacelle there is a lightweight sledge available for performing squats or a nacelle with a bicycle ergometer.
