FURTHER INFORMATION

Projects

Pyeongchang

SLF is supporting Swiss athletes and their support teams in Pyeongchang with exclusive snow and weather forecasts.

Inspiriert vom mechanischen Verhalten des Schildkrötenpanzer wurde ein Ski entwickelt, dessen Steifigkeit bei grösserere Beanspruchung zunimmt. Bei der Entwicklung wurden FE-Simulationen, Labormessungen und Fahrttests eingesetzt.

Water loss and artificial snowmaking

The SLF is examining how much of the water ejected by snow lances is not transformed into snow on the ground.

Energy and Resources Use in Mountain Destinations

The project is dealing with an optimization of the consumption of energy and water resources in alpine ski resorts. To do so we perform a detailed analysis and modelling of snowmaking processes and water balances of ski resorts.

Nessy Zero E

Based on the project NESSy in which a new and energy efficient snow lance was developed, the following project pursues the development of a zero energy snow lance that takes the all the required energy completely from the surrounding.
