Textron Nexus 4EX
The Nexus 4EX (concept) is a tiltrotor eVTOL/hybrid eVTOL for extended range models being developed by Textron eAviation. Entry into service is targeted for 2030 and certification is to be sought from the FAA under part 21.17b and likely EASA under the SC-VTOL enhanced category.
Structure and Powertrain
The 4EX seats four passengers and pilot within the composite fuselage. The aircraft features a high wing, four tiltrotors, two lift fans, tricycle landing gear, and a vertical rear rudder. The tiltrotors/fans are each individually powered by an electric motor and the Pipistrel battery system.
Distributed electric propulsion (DEP) is the name given to this method of powering aircraft. No critical points of failure provide a high level of redundancy and will ensure safety onboard. Other safety features include the aircraft’s ability to land conventionally if necessary.
