As First Flight Approaches, Eviation Founder Explains How and Why Alice Got a New Look

With ground testing far advanced, Eviation expects the Alice to start its flight test campaign from its new headquarters in Washington state by the end of 2021.
Concerns over type certification complexity as well as input from prospective customers were behind Eviation's decision to move the propellers of its all-electric Alice aircraft from the wingtips to the tail. The company, which is targeting passenger and freight applications for the all-electric aircraft from 2024, says the new configuration will result in greater stability and enhanced fly-by-wire performance, while also delivering more power from its larger propellers.

Hybrid Air Vehicles Makes the Case for Its Airship to Replace Airliners

With a spacious cabin seating up to 100 passengers and low carbon emissions, the hybrid-electric Airlander 10 airship is being offered for roles including luxury travel and scheduled regional airline routes.
UK-based Hybrid Air Vehicles (HAV) has unveiled cabin concept designs for its under-development Airlander 10 passenger airship. The company is raising funds to prepare the hybrid-electric aircraft for service entry in 2025, with an all-electric version to follow in 2030. It says the airship's low environmental footprint and ability to operate in city centers make it a viable alternative to airline services.

Infrastructure Needs For eSTOL and eVTOL Aircraft May Be Closer Than Imagined

eSTOL aircraft developer Airflow maintains that the performance of its blown wing design could match or exceed that of eVTOLs in terms of real estate needs on the ground.
Speaking at the recent Vertical Flight Society Electric VTOL Symposium, Airflow CEO Marc Ausmus described the runway needs of his proposed hybrid-electric aircraft as being 150 feet of ground roll with an overall requirement of 300 feet in length, roughly three times the length of the currently proscribed touchdown-and-liftoff (TLOF) area plus safety zone, for a helipad.

French Start-up to Flight Test Compact Turbogenerator For Hybrid-Electric Aircraft

French manufacturer Turbotech plans to flight test its under-development turbogenerator later this year, claiming it will provide transformative power options for hybrid-electric aircraft.
While some hybrid-electric aircraft systems under development use an engine connected to a generator through a gearbox of some sort, Turbotech has developed a compact all-in-one unit that uses a microturbine, a generator, and a heat exchanger, all on the same shaft. It spins at 9,000 rpm providing a high power-to-weight ratio.
