Financial pressure on eVTOL aircraft developer Volocopter appears to have eased, with confirmation last week that the German company has secured further funding. In a short written statement the company said that it has secured finance from several existing undisclosed shareholders, but it refused to identify these backers.

Lilium has told investors it is sticking to a “disciplined approach” to completing type certification of its four- to six-passenger eVTOL aircraft by the end of 2025. In a letter to shareholders published on Tuesday, the company said it ended the first quarter with €102 million ($109 million) in unaudited liquidity.

For decades, the team at TE Connectivity (TE) has been helping design safe and efficient electrical power management systems for everything from military planes to moon landers. Now TE is supporting a new frontier: the emerging Electric Vertical Takeoff and Landing (eVTOL) industry.

The FAA has issued a Part 135 air carrier and operator certificate to Archer Aviation, permitting the eVTOL manufacturer to begin on-demand commercial air taxi operations. While the company works to complete the type certification process for its Midnight eVTOL air taxi, it can use already-certified conventional airplanes to refine its systems and procedures.

Eve Air Mobility has appointed more suppliers for its eVTOL aircraft, including the windows, doors, and other elements of the fuselage. KRD Luftfahrttechnik in Germany will provide polycarbonate windows, and French aerostructures group Latécoère will supply the doors. Brazilian suppliers Rallc and Alltec will provide molds and composite materials for various fuselage components.

European helicopter operator Avincis is partnering with Airbus to develop plans for eVTOL operations, especially for emergency medical services, search and rescue, and firefighting. Under a memorandum of understanding signed at the ILA airshow in Berlin last week, the companies said they would define concepts of operations for service in Europe and other regions.

Mesa Air Group this week confirmed it has provisionally committed to buying up to 100 of XTI Aerospace’s TriFan 600 VTOL aircraft. The sales commitment had been kept confidential until June 5, when the holding company for regional airline Mesa Airlines agreed to let the Colorado-based start-up publicize the deal.

Private flight platform Skycab has launched a partnership aimed at developing applications for Manta Aircraft’s planned hybrid-electric aircraft that will operate in both vertical and short takeoff and landing modes. The companies launched the collaboration in early June, publishing examples of how the Ann family of aircraft could offer alternatives to helicopters, cars, trains, and ferries on domestic routes in Italy.

As it steps up flight testing in its campaign to secure FAA type certification for its Midnight four-passenger eVTOL aircraft, Archer has been extending the operational envelope. This week, the company released a video showing a test aircraft transitioning from vertical to horizontal cruise flight at speeds above 100 mph.
