Hybrid propulsion airplanes – market and experience
Miguel Angel Suarez Sanchez CEO Axter Aerospace SL SPAIN
The presentation will offer an introduction to parallel, series-hybrid and full-electric propulsion for aviation, and outline the benefits of parallel hybrid for light and general aviation. It will also cover experience with parallel-hybrid configuration with light airplanes (two and four seaters); real test data and customer experience; the hybrid market and society demands; and the next steps in hybrid technology development.
i-UAM – an option to reinvigorate general aviation
Dr Rene Nardi Business development director Alltec USA
I-UAM or Inter-Urban Air Mobility, as addressed by this paper, refers to air transportation activities designed for small groups of two to six passengers traveling relatively short distances between two locations, 200-300 miles apart. Those first few hundred miles is where general aviation can make a big impact on business and tourist travelers, going directly where they want and when they want. This paper describes some of the challenges and opportunities that arise once technology with unprecedented power transforms the small general aviation aircraft. The personal aircraft entering into service by 2025 will be simpler to operate and more capable than today’s aircraft.
E-rop – electric and rotary-engined hybrid plane
Stefan Senger CEO AdvanTec GmbH GERMANY
E-rop is a development project of a single-seat plane, that is equipped with an electric engine in the nose (front electric sustainer) and a Wankel-generator combination (REX) in the rear compartment. The main battery is positioned in the wing. With the combination of batteries and the REX, the plane is able to fly more than 2,500km.
Tilt-wing eVTOL aircraft conceptual design and development
David Fillingham Research engineer Rolls-Royce UK
This paper will cover the conceptual design and development of a tilt-wing eVTOL aircraft concept aimed at improving urban mobility. The paper will cover the basic conceptual design, the aerodynamic and control system challenges and lessons learned during the flight testing of a scale model.

More-electric aircraft concept applied to regional jets
Hernane Catanoso Lino de Souza Aircraft system development engineer Delta System Solutions GERMANY
The objective of this work is to understand why the MEA concept is not used for new regional jet development. The goal is to present a parameter to be calculated during the initial development phases, considering the following parameters: MTOW, maximum range and fuel volume. The parameter should be capable of identifying if a new development should be developed by MEA or conventional technologies.
Technical challenges in designing electrical machines for eVTOL applications
Dr Mircea Popescu Chief technology officer Motor Design Ltd UK
James Z de Ferranti General manager Denis Ferranti Group UK
Electrical machines for aerospace in general and particularly for eVTOL applications require high power and torque density and safe operation for passengers and/or crew. These requirements can be achieved with specific configurations. This presentation shows potential solutions using rare earth permanent magnets or induction and switched- reluctance technology. State-of-the-art materials and innovative technical ideas are required to ensure safe behavior.
Analysis of a convertible aircraft concept with a hybrid powerplant
Sergey Yegoshin Engineer TsAGI RUSSIA
Andrey Redkin Lead engineer TsAGI RUSSIA
Research has been carried out to determine the rational concept and operating efficiency of a convertible aircraft with a multirotor lifting system and a hybrid powerplant for passenger transportation to remote settlements without airfields. In this paper, several concepts of convertible aircraft were analyzed. They differ in the following key features: the number and location of the lifting rotors; the method of fixing, folding and retraction for lifting rotors, or the use of tilt rotor groups; the main cruise engines and rotor (propeller) positioning; the new wing geometry.
The boosted turbofan for electrified aircraft: the TRADE perspective
Dr Michael Sielemann Aerospace industry director Modelon GERMANY
The boosted turbofan is a highly relevant concept to achieve improvements in fuel efficiency and emissions, which are required due to the amount of air travel worldwide. Limited detailed results have been reported on the boosted turbofan concept taking constraints from the gas turbine cycle and the electrical system into account (e.g. impact on surge margin, interaction with handling bleed). This presentation summarizes the results of the Turbo electRic Aircraft Design Environment (TRADE) project, which develops a physics-based simulation/optimization platform for such applications. Results are presented and discussed in relation to the (still limited) scientific literature.
