Hybrid and electric propulsion is shaping the future of the aviation industry. In the race to bring the new propulsion concepts to global markets and provide safe, secure and sustainable mobility services, aerospace designers and engineers are looking to many different technologies to address the associated challenges. In particular, challenges in EMC and system integration represent uncharted waters in the new aviation era but are fundamental for providing business-critical capabilities such as autonomous flight, inflight connectivity, communication links and flight navigation.

Use of wingtip propulsion and lifting body for electric aircraft design

Serafín Escudero
R&D project leader/technical leader
Altran
SPAIN
Recent studies and forecasts suggest that to achieve a reduction in greenhouse emissions, the aeronautical industry must evolve into more efficient solutions based on electric technologies. Altran’s current strategy looks into hybrid and electric R&D projects. This paper is focused on the development of new solutions applied to an electric aircraft, under FAR CS-23 regulations, with 20kft cruise ceiling, two hours endurance plus 30 minutes contingency flight, and propulsive efficiency enhancements such as a state-of-the-art wingtip propulsive system and lifting body. Analytical calculations and CFD studies are presented for different configurations and geometries, changing the perspective on design methodologies.

Concept of electrical power transfer for turbofan engine performance enhancement

Serhiy Bozhko
Director
Institute for Aerospace Technology, University of Nottingham
UK
Turbofan engines are designed for optimum performance in cruise conditions, with certain operational constraints in other flight scenarios due to thermodynamic coupling between low-pressure (LP) and high-pressure (HP) shafts. Considering that in the more-electric engines (MEE) the power is considered to be extracted by electrical machines that are mounted on both the HP and LP shafts, the study investigates the potential of further engine performance improvements by controlled electrical power transfer between the shafts, seeking for optimized operation depending on engine operating mode (EOM).

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.

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.
