Thermal and Pneumatic Systems (TePS)

The TePS project takes a major step forward in the technology required to enable electric and hydrogen-powered flight. The goal is to develop and demonstrate this technology through collaboration between universities, research institutions, and industry. The focus is on developing systems necessary for supplying conditioned air and for cooling applications.

TePS builds upon several initiatives launched by its partners. For instance, Aeronamic has made significant progress in the development of electric turbomachinery, Collins Aerospace has advanced heat exchanger technology, and NLR/TUD/UT have worked on simulation models and test setups. Together, these parties form a strong partnership capable of making a substantial leap forward.

Fuel cells require compressed, filtered, and cooled air before being supplied to the fuel cell. TePS is developing a system to fulfill this function, working closely with the LiT project HAPSS.

Electric flight requires battery temperature conditioning to ensure optimal flight range. TePS will develop an advanced system to regulate battery temperature using a two-phase coolant.

Cabin air treatment changes with hydrogen and electric flight. TePS addresses this by developing a cooling system based on the inverse Rankine cycle (Vapor Cycle System).
