This achievement signals the start of Overair's vehicle level testing phase at its Santa Ana, California headquarters, before moving the aircraft to their expansive flight test facility in Victorville, California.
Initial tests, scheduled to begin in early 2024, will focus on validating Butterfly’s propulsion systems, flight control mechanics, safety features, and operational efficiency.
The testing will also assess the aircraft's 55-decibel noise target and performance envelope across diverse flight and weather conditions.

OVERAIR, INC. COMMENCES PROPULSION TESTING FOR BUTTERFLY EVTOL VEHICLE

Overair's vectored thrust design is aerodynamically efficient and takes best advantage of the company's unique technology inherited from Karem Aircraft. Butterfly is a fundamentally different vehicle than other EVTOLs. It leverages Overair's proprietary propulsion design with very large propellers relative to other EVTOLs, while also relying on highly efficient wing-borne flight for cruising over longer distances. As a result of their size, Butterfly's propellers can spin slower during various phases of operation (hover, transition, cruise), which makes them quieter and draw less power from the batteries. Thanks to substantial power and control margins, these large propellers provide unmatched efficiency -- an incredibly important attribute when flying high-tempo urban routes in varied environments.

Key Points:

Some of the most important attributes of an eVTOL aircraft are safety, community acceptance, and economic productivity in real-world conditions, each of which is largely dictated by the vehicle's propulsion system.
The achievement of this testing empowers Overair to confirm its design choices early in development.
"Achieving our full-scale propulsion test goals is an exciting milestone for the Butterfly program" said Jim Orbon, Butterfly Program Manager at Overair.
Overair will continue to execute their Butterfly program as efficiently as possible, focusing on certification as the finish line.
