THEMA4HERA

The ambition of TheMa4HERA is to demonstrate the dissipation of required additional heat in the order of 20 to 50 kW for systems and 300 to 1000 kW for power storage and generation in batteries, the APU and fuel cells in the hybrid electric regional aircraft versus today’s similar size aircraft generating around 35-50 kW of heat.  The main challenges are related to heat loads increase, low grade heat and sensitivity to overheat (low temperature differences between cooling source and sink), and either no or less heat exhaust depending on bleed architecture. The project is therefore a key enabler of hybrid electric aircraft concepts and will go beyond the state-of-the-art using a combination of novel technologies with optimization at aircraft system level (i.e. novel architecture).  TheMa4HERA is gathering a wide range of partners, ranging from key industry players, through SMEs, Research Institutes to Universities. Aside from the competitive advantage that the project will give its contributors, one of the main benefit of the project is that it enables aircraft electrification and use of non-drop-in power sources such as fuel cell, hydrogen and batteries.
