Created by Embraer, Eve Air Mobility advances in the testing phase of the eVTOL aircraft

Eve Air Mobility, a company created by Embraer, announced today, May 26, that it continues to advance in the testing phase of its electric vertical take-off and landing (eVTOL) aircraft, evolving towards fundamental milestones of the program. The various tests carried out throughout this phase are part of Eve’s building blocks approach, which seeks to increase the maturity of the technology and the eVTOL to offer the best product to the market. In Brazil, Eve completed testing of the booster in its test environment (RIG) in order to measure aerodynamic performance and sonic properties for modeling and development. The number and general characteristics of the blades (twist, shape, etc.) are critical in defining the vibration, load and sound profile, as well as the energy requirements of the eVTOL. Engineers tested various models to improve efficiency, reduce sound impact, and reduce operating costs. The company has also recently begun testing its vertical lift rotors aboard a new custom truck-mounted platform. The mobile equipment was specifically designed to evaluate the performance of the rotors during the transition phase of flight. The engineering team has already started testing and collecting data on the aerodynamic characteristics of the rotors during forward flight. Eve’s aircraft features a Lift + Cruise configuration with dedicated rotors for vertical flight and fixed wings for cruising without the need for in-flight transition components. This configuration favors safety, efficiency, reliability, and certifiability, while reducing operational, maintenance, repair, and overhaul costs. The results of the company’s recent wind tunnel tests, along with propulsion and rotor test findings, are being used to increase the fidelity of the company’s flight simulator and fly-by-wire system. Eve is also using learnings gained from improved Computational Fluid Dynamics (CFD) calculations to improve analysis of the transition between hover and cruise phases, among other tools. Eve expects to complete selection of key equipment suppliers in the first half of 2023 and begin assembly of the first prototype eVTOL during the second half of 2023, followed by the testing campaign in 2024. Eve’s eVTOL is scheduled to be certified and enter service in 2026. – Criada pela Embraer, Eve Air Mobility avança fase de testes da aeronave eVTOL (aeroin.net)
