Eve Air Mobility (“Eve”) (NYSE: EVEX, EVEXW), a leading player in the electric vertical take-off and landing (eVTOL) industry, has made significant strides in its testing phase as it moves closer to achieving key program milestones. Eve’s commitment to a building-blocks approach helps ensure the continuous enhancement of its technology and eVTOL aircraft, allowing for the delivery of a highly effective product to the market.

Eve Air Mobility, a spinoff from EmbraerX, is creating a unique eVTOL aircraft focused on efficiency, safety, low-noise profiles, and ultimately on making short-distance air travel more acccessible.

Eve recently completed propeller tests on its propeller rig in Brazil, focusing on measuring aerodynamic performance and sound properties for modeling and development purposes. The configuration and characteristics of propeller blades, such as torsion, shape, and quantity, are crucial in defining the vibration, load, and sound profile of the eVTOL. Additionally, they impact the energy requirements of the aircraft. By testing multiple models, Eve’s engineers are striving to enhance efficiency, reduce sound footprint, and lower operating costs.

In another significant development, Eve has commenced testing its vertical lift rotors on a specially designed truck-mounted platform. This mobile testbed aims to evaluate the performance of the rotors during the transition phase of flight. Eve’s engineering team is actively gathering data on the aerodynamic characteristics of the rotors in forward flight. The eVTOL by Eve employs a lift and cruise configuration, utilizing dedicated rotors for vertical flight and fixed wings for cruising. This configuration prioritizes safety, efficiency, reliability, and certifiability while simultaneously reducing operational costs and additional maintenance and repair expenses.

Alice Altissimo, the Vice President of Program Management and Operation at Eve, expressed satisfaction with the company’s program development activities thus far. Altissimo stated, “We are very pleased with our program development activities to date and making very good progress as we move toward the selection of primary suppliers and finalize the definition of our aircraft systems architecture. We continue to invest, and our team is working hard with the goal of developing a mature aircraft for certification and entry into service in 2026.”

Anticipating progress in the near future, Eve expects to finalize the selection of primary equipment suppliers in the first half of 2023. Subsequently, the company plans to commence the assembly of its first full-scale eVTOL prototype in the second half of 2023, followed by an extensive test campaign in 2024. Eve’s eVTOL is scheduled to achieve certification and enter service by 2026.

Collaborating with various partners, Eve is dedicated to accelerating the Urban Air Mobility ecosystem. Benefiting from a start-up mindset and backed by Embraer S.A.’s over 50-year history of aerospace expertise, Eve is taking a holistic approach to advancing the UAM ecosystem. Alongside its advanced eVTOL project, Eve provides a comprehensive global services and support network, as well as a unique air traffic management solution.

Why it’s important: By continuously enhancing its eVTOL technology through rigorous testing and collaborating with key partners, Eve is bringing its product closer to certification and commercialization. These developments signify the Eve’s commitment creating an eVTOL aircraft that can be certified in all parts of the world, and can be used to create reliable and versatile aerial mobility networks. By bringing its immense wealth of expertise to this new industry, Embraer’s Eve has immense potential to create an advanced and high-functioning aircraft, as well as the networks and software systems to help operate it.
