Towards the 2050 carbon neutral objective

Dr Karim Mokaddem
Head of electrification
Airbus
France
The Airbus electrification journey started a few years ago with the E-Fan demonstrators, followed by the launch of Vahana, which paved the way to all-electric vertical flight, confirmed today with the CityAirbus NextGen demonstrator. To reach the Air Transport Action Group (ATAG) goals aimed at stabilizing CO2 emissions with carbon-neutral growth and reducing net emissions from air travel, Airbus is investing its research efforts in electrification by exploring some of the key technologies of hybridization, such as e-motors, power distribution, motor controllers and new architectures. In this journey, electric flight demonstrators are crucial stepping stones to explore different sets of technologies ranging from incremental improvements to revolutionary technologies like hybridization and fully electric UAM platforms, toward disruption with hydrogen or superconductivity. In this talk we will share Airbus’s group-wide energy sustainability efforts toward clean aerospace and a net-zero carbon footprint for the 2050 horizon.

The design process for electrically-propelled aircraft

Dr Peter Malkin
Strategic research advisor
Newcastle University
UK
Most large aircraft currently use twin turbofans and the design process for these is well established. Moving to electrical propulsion doesn't just impact the propulsion system but fundamentally alters the way in which the whole aircraft must be designed from the first panel to final testing, including the aerodynamic design. This may seem far fetched to some readers and the effect of bias from electrical engineers, however, the fundamental differences in scaling and safety design approaches mean there is no other option. Furthermore, the design now has to be fully integrated to the point where individual product specifications can no longer be issued by the designer or airframer but must be developed as part of the design. This directly impacts the supply chain, which in fact must become part of the design authority for the aircraft. These three key effects will be outlined in the paper and examples will be given in each case that leads to radical changes to aircraft design.

Hybrid powerplants plus sustainable fuels to achieve zero net carbon

Eric Bartsch
CEO
VerdeGo Aero
USA
Hybrid electric power provides electric aircraft with greater energy density and significantly expanded mission performance while also reducing fuel consumption. Sustainable aviation fuels (SAFs) provide a net-zero carbon cycle for operating aircraft. The intersection of hybrids and SAFs creates an interesting design space for the highest performing, lowest technology risk, lowest operating cost method for achieving zero net carbon flight. The high efficiency of diesel cycle engines operating on SAF accelerates the adoption of SAF as the price of sustainable fuels reduces over time at a faster rate than battery energy density and cycle lifetime improve.

Key steps towards vertical mobility from VTOL developer's point of view

Mohammad Reza Marghoubkar
Head of operations
Samad Aerospace Limited
UK
With the advent of jet engines, we have seen the success and a plethora of opportunities unlocked following the second aviation revolution that made international travel possible. What if we can replicate such successful connectivity at a closer level? And what if the key to unlocking such closer connectivity lies in vertical mobility? To answer these questions, one cannot help but delve deeper into the implementation of air taxis within an urban setting in the aspirations of UAM. However, one may be taking a step too far. A possible correct step forward is to move from achieving connectivity at the regional to subregional level before we attempt to deploy vertical UAM. Vertical mobility in the subregional context is intercity air travel that is safe, sustainable and accessible for everyone in the near future.

Hybrid electric propulsion to make advanced air mobility practical today

Diana Siegel
Director of strategy
Electra.aero
Switzerland
A large share of advanced air mobility vehicle designs leverage distributed electric propulsion to achieve new capabilities such as vertical or very short take-off and landing, more quiet operation or more efficient cruise. However, battery electric energy storage heavily limits range and limits the payload such a vehicle can carry. Hybrid electric propulsion resolves this challenge - allowing aircraft designs to reap the benefits of distributed electric propulsion while maintaining payload and range capability. Electra.Aero has designed and tested a custom battery and turbogenerator hybrid electric propulsion system for integration into its eSTOL manned flight demonstrator. This presentation discusses the hybrid electric architecture, test results and learnings from this development effort.

System-level optimization of electrical power units (EPU) for eVTOL aircraft

Ajay Lukha
Chief commercial officer (CCO)
Evolito
UK
Behind the hundreds of proposed eVTOL architectural concepts in current development, there are thousands of engineers working to design the best electrical power unit (EPU) for their chosen application. Since every kilogram must be lifted, there’s ever-growing pressure to keep the mass at an optimal low while ensuring the safety and reliability of the design from an EPU that’s manufacturable in volume at an economically feasible cost. Without any clear industry leader and regulations still evolving, there is no established consensus on which solution will dominate each market opportunity, with companies looking simultaneously at direct drive or geared EPUs for multi-motor, lift and cruise, tilt rotor aircraft or hybrid archetypes. In this study, we use a multi-objective genetic algorithm to design an EPU for an example e-VTOL application. We quantify the link between the EPU mass and efficiency for three different architectures – direct drive, geared and series motor solutions – based on the well-known YASA axial flux technology that is now being brought to market by Evolito. We then investigate the impact of that mass-efficiency coupling on an example e-VTOL aircraft performance.

Gallium nitride inverter for eVTOLs

Dr Temoc Rodriguez
Chief engineer, power electronics and drives
Ricardo Plc
UK
eVTOLs are characterized by their multirotor configuration for redundancy and stability, each rotor providing a power level from a few kW to tens of kW. Inverter switching technology ranges from silicon MOSFETs and IGBTs to the more modern silicon carbide transistors. However, gallium nitride technology has the potential of increased efficiency over these technologies. This would reduce the size and weight of the inverter as the thermal rejection system can be made smaller. This presentation will show the results of the GaN inverter powering a 50kW machine suitable for eVTOL applications.
