Overview

fLHYing tank is an Innovation Action within the European Commission’s Horizon Joint Undertaking Clean Aviation program under Grant Agreement No. 101101946.

The team of fLHYing tank comprises Pipistrel Vertical Solutions as the coordinator of the project and Peak Technology Gmbh, TEST-FUCHS Gmbh, von Karman Institute for Fluid Dynamics and University of Patras as partners.

The overall objectives of fLHYing tank are the definition of requirements for the design, manufacturing and qualification of a 1,000-liter vacuum insulated composite LH2 storage system, including all required peripherals for filling, pressure control, hydrogen output, boil-off management, safety equipment, leak detection and health monitoring, as well as instrumentation for the thermo-fluid-structural characterization of the system. Furthermore, the manufactured storage system is planned to be flight-tested in the Pipistrel Nuuva V300 hybrid-electric VTOL unmanned cargo aircraft, and a thermo-fluid-structural digital twin of the system will be developed and validated. The designed LH2 fuel tank is targeting small commuter aircraft, such as the Pipistrel Miniliner concept.

The main impact of the fLHYing tank project is the unprecedented reduction in the time-to-market of revolutionary technologies in the aeronautical industry, thanks to the ground-breaking fast-track flight testing of a relevant-scale composite LH2 storage system using a UAV, achieving comprehensive understanding of the behaviour of LH2 tanks in the flight environment within minimum timeframe, risk, and cost. This ambitious goal can be achieved within the 1st phase of the Clean Aviation Programme thanks to the fLHYing tank project.

Clean Aviation Joint Undertaking

The Clean Aviation Joint Undertaking is the European Union’s leading research and innovation programme for transforming aviation towards a sustainable and climate neutral future. Pulling together the best talent and capabilities of the private and public sectors and developing cutting-edge technologies and making these available for a transformational leap in aircraft performance in the 2030s, the new Clean Aviation Joint Undertaking will pave the way towards the EU’s ambition of climate neutrality by 2050.
