Peak Technology develops satellite tanks for the ESA

The demands imposed upon the fuel tanks are particularly stringent. On the one hand, they should safely bring the satellites to their pre-defined orbits. On the other hand, they should dissolve completely upon re-entry into the Earth's atmosphere.
For this purpose, Peak Technology relies on new materials. The titanium usually in use is replaced by aluminium and the heat resistance of the carbon fibre sheath is lowered. The tank consists of an extra-thin inner layer of aluminium, which is filled with krypton or xenon and encased in carbon fibre.

Due to the enormous cost of a satellite launch, there is no fault tolerance at all. That is why Peak Technology not only works with external partners for the simulation, but also with the Austrian Foundry Institute (OGI) in Leoben and Hypersonic Technology Göttingen GmbH (HTG) specialising in re-entry analyses and satellite aerodynamics.

First launches scheduled for 2021

Peak Technology engineers began development work on the ESA project in June 2019. This work should be completed by the end of 2020. In the middle of 2021, the first fuel tanks from Austria will likely begin their journey into orbit.

Many-body quantum physics

Many of the biggest questions in physics can be answered with the help of quantum field theories: They are needed to describe the dynamics of many interacting particles. These theories are just as essential in solid state physics as they are in cosmology.

Growing demand for natural active ingredients enables Phytovalley Tyrol to flourish

The comeback of plant-based active ingredients in medicine, cosmetics and food production has positive impacts on Tyrol as a business location. Austria has succeeded in playing a pioneering role in plant research thanks to the support of the federal government, the Federal Province of Tyrol, the company Bionorica and the University of Innsbruck. This niche in plant research already established itself in Innsbruck years ago.
