In 2021, Ampaire’s six-seat hybrid electric broke the record for the longest distance flown with a hybrid electric aircraft, by flying 418 nautical miles and proving that range is not an issue for hybrid electric aircraft as opposed to fully electric aircraft. Long and short flights performed with the hybrid electric aircraft have shown fuel savings of over 30% compared with the baseline existing airframe. Clean-sheet designs will allow further fuel savings due to reductions in ballast by eliminating parts that are no longer needed. Furthermore, using a 100% SAF blend in hybrid electric aircraft will reduce direct net CO2 emissions to near zero.

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.

Demand modeling for advanced air mobility – new data teaching an old dog a new trick

Darrell Swanson
Director
Swanson Aviation Consultancy Ltd
UK
This presentation offers a brief description of the Advanced Air Mobility Mode Shift Demand Modelling technique developed by Swanson Aviation Consultancy and Aveo Advisory. It sets out how we use novel data sources combined with traditional and new demand modeling techniques to identify passengers who will switch from road and rail modes of transport to AAM modes of travel. We can forecast the number of passengers and then develop indicative schedules needed to service the demand. The scheduling analysis provides insights into the number of aircraft required, annual utilization, carbon emissions savings over other modes of transport, infrastructure requirements including peak power requirements and mitigation techniques. This analysis provides insights that investors need to make investment decisions, including OEMs, operators and landing infrastructure providers.

The presentation focuses on the design of a safe, all-electric multirotor propulsion system for urban air mobility (UAM) vehicles, in particular, future air taxis as analyzed within the German Aerospace Center project ‘HorizonUAM’. Meeting the highly demanding certification requirements in terms of system reliability of an all-electric multirotor propulsion system is a major system design challenge. Additional difficulties that need to be considered include the power supply, thermal management and the interaction of flight control and propulsion functions. Using a model-based systems engineering approach, the safety-critical design aspects will be analyzed and different propulsion system architectures will be discussed.

Advanced Air Mobility (AAM) is a broad concept focusing on emerging markets and use cases for aviation in urban, suburban, and rural communities. Technological advances are quickly pushing AAM from the fringe to the mainstream, and cities and states have begun to plan for the integration of aviation into their transportation and urban planning. However, as an emerging concept, AAM will face many barriers, such as safety; the regulatory environment; airspace access; noise; community acceptance; environmental impacts; infrastructure; intermodalism; and security. In this presentation, attendees will learn about the opportunities and challenges of integrating advanced air mobility into communities and transportation systems.

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.

Preliminary design of an eVTOL aircraft with ducted fans

Carlos Castro
Director customer services
PACE GmbH
Germany
Hybrid-electric propulsion technology enables the investigation of new aircraft concepts to develop new case studies and solutions to meet the ever-changing needs of modern society. Urban air mobility (UAM) is on its way to becoming a reality in the near future, and industries are keeping up with modeling and simulation. Distributed propulsion increases the feasibility and flexibility of eVTOL, making it a research topic of focus in the aerospace world. This presentation introduces a parametric model of such an aircraft, propelled by electric ducted fans (EDF). Existing models described in the literature do not include vertical take-off or hovering procedures as sizing conditions. This presentation will show how such new methodology can be implemented and applied to an eVTOL concept using the Pacelab APD commercial preliminary design software platform.

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.
