For investigations of combustion processes scientists may conduct associated experiments in ZARM's Hot Wind Tunnel.
In the Drop Tower Bremen at ZARM scientists may perform short-term experiments under high-quality conditions of weightlessness.
With the 30g - Centrifuge at ZARM scientists and customers from industry may conduct hypergravity experiments and test of aerospace components.
ZARM's Vibration Test Laboratory (Shaker Test Stand) offers the opportunity to qualify aerospace experiments or single components.
For experiments in Fluid Mechanics ZARM provides a Hypersonic Wind Tunnel and a Circulating Water Tunnel.
ZARM's Circulating Water Tunnel provides variable flow rates of up to 15 m/s and is capable to operate in different operation modes for the investigation of cavitation effects.
For hypergravity experiments and especially for tests of aerospace components the ZARM 30g - Centrifuge is capable to provide continuously variable accelerations of up to 30 g.
ZARM's Hypersonic Wind Tunnel has the ability to offer short-term measurements in supersonic or hypersonic flows. Wind velocities in the range of Ma 6 to Ma 11 are realized with this facility.
According to international qualification standards the available Shaker Test Stand offers the opportunity of performing mechanical shock tests in the frequency range of 5 Hz to 3000 Hz with maximal shocks of up to 220 g.
The Drop Tower Bremen represents an economic and permanently accessible alternative conducting short-term experiments under conditions of weightlessness (experiment durations of up to 9.3 s). Furthermore, the chronology of different drop tower experiments is very flexible (with up to 3 operations per working day). In comparison to other platforms providing weightlessness ZARM's quality of weightlessness at 10(-6) g (microgravity) is one of the purest worldwide achieved.
Adequate high temperatures and high pressures at low to medium flow rates ensure reproducible conditions to experimentally investigate processes of combustion in the Hot Wind Tunnel at ZARM.
