10.-13.04.19 Hy4 on the Aero 2019

Within the project of  MAHEPA (Modular Approach to Hybrid Electric Propulsion System), a 1: 5 scaled model of the Hy4 will be presented at the Aero 2019 in Friedrichshafen. The Aero is one of the largest international trade fairs for general aviation. “With more than 600 exhibitors from 35 nations, 33,000 visitors and 600 journalists from all over the world, AERO Friedrichshafen is the world’s most important annual gathering place for the community”. (Source: Aero). The model of the Hy4 will be exhibited in Hall A7 on the E-Flight Expo. The development engineers of the Hy4 address the questions of the public and show the advantages of hydrogen fuel cell technology as main propulsion for aircraft.

28.03. – 29.03.2019, E2Flight Symposium

The E2Flight Symposium was held at the Stuttgart Airport in 2015 for the first time. The feedback was excellent and due to the popular demand we will be holding the 4th edition of this symposium.

This year we will have a close look at new projects and we will discuss the progress of relevant aspects of electric flight. 

In 2016, the DLR and the University of Stuttgart examined the challenges and opportunities presented by electric propulsion in aircraft.

2017 the focus was on new aspects of electric flight like the feasibility as well as the scientific aspects of this new and promising technology.

We are pleased to invite you to join us for the 4th Symposium on the 28th and 29th of March 2019.

Main Targets

  • Overall concepts for electric flight

  • Energy and systems

  • Batteries, fuel cells, refueling, charging, and required infrastructure

  • Hybrid electric systems including internal combustion engines and generators

  • Inverters, energy transfer, and electric motors

  • Aspects of certification

  • Aircraft projects and system integration

05-06.10.2017, Stuttgart Symposium E2Flight

05-06.10.2017, Stuttgart Symposium E2Flight

One of the biggest symposia on electric flying took place in Stuttgart under the main topics “Technological and Political Progress in Electric Flight”, “Hybrid Systems and Energy Storage”, “Energy Conversion, Safety and Certification Aspects” and “Integration Aspects and Flying Hardware” , Organized and carried out by the German Aerospace Center together with the University of Ulm, the latest findings on electrification of aviation were exchanged in lectures and discussions with renowned representatives from industry and research. Lectures by Frauke Pleins-Schmidt from the German Federal Ministry of Transport and Digital Infrastructure, Starr Ginn from the NASA Armstron Flight Research Center and Prof. Josef Kallo from the University of Ulm show only a fraction of the high-caliber lectures and participants. In addition, the forum was used to make contacts and share know-how. This Syposium once again showed the positive trend of technology development and gives hope that electric aircraft will be soon mass produced and operated.

21.07.2017, Ulm – Silent and quiet, the Hy4 inspires about 7000 visitors during the Long Night of Science at the University of Ulm.

The H2Fly GmbH shows with the Hy4 as part of the Long Night of Science at the University of Ulm how the future of aviation will look like. Quiet as the night, the Hy4 flies with its emission-free hydrogen fuel cell – battery hybrid system. The approximately 7,000 visitors had the opportunity to learn about the new drive technology and its possibilities and to discuss the development of the market for emission-free aircraft and the value of this new development with the engineers. In the aviation industry H2Fly GmbH is already known as a trend-setting company with an intensive focus on the development of emission-free aviation. As part of the Long Night of Science, all interested parties were also able to find out how the company fullfill the work around the aircraft and supports the Institute for Energy Conversion and Storage from the University of Ulm as a partner in the development of power electronics for the Hy4. The exhibition was supported by the scientists of the institute, who were able to explain their work in detail. They explained that work is currently being done on the further development of power electronics.

01.07.2017, Planning for Symposium E2Flying in the hot phase

After the response to the symposium had been tremendous, the organizers decided to host the symposium at Stuttgart Airport again this year, after 2015 and 2016. The focus is on the development of overall concepts for electric flight, system development and approval
