Sewell, New Jersey, USA

Jaunt Air Mobility is a start-up company founded in May 2018. It is currently raising capital to use slowed-rotor technology developed by Carter Aviation to take part in the Uber Elevate program for flying taxis.

Jaunt is a single-rotor compound helicopter that incorporates a patented rotor system, which enables both VTOL and high-speed flight. The rotor system is capable of reducing the hover RPM to one-third for cruise, which significantly reduces noise and drag. The rotor lift and speed are reduced in accordance with speed until approximately 150 knots, where the wing is providing all the lift and the rotor is completely unloaded and free-spinning to minimize drag.

Jaunt Air Mobility plans to flight test a modified airworthy SRC in 2019, in two configurations: a hybrid version, followed by an eVTOL configuration. The power management system design and integration is being supplied by Portland, Oregon-based Volta Companies, makers of the electric-powered Volta Volaré and four-seat DaVinci aircraft. The flight test data will help in developing the next generation of an all-electric SRC in conformance with Uber’s Elevate urban air mobility requirements.

Jaunt Air Mobility LLC is developing an all-electric Vertical Take-Off and Landing (eVTOL) aircraft designed for the Urban Air Mobility (UAM) and On-Demand Mobility (ODM) markets. Jaunt Air Mobility is a Reduced-rotor Operating Speed Aircraft (ROSA™) with core technologies proven in over 250 hours of successful demonstration flights and represents the merger of the best features available from both helicopters and fixed-wing airplanes.

The ROSA™ technologies include several innovative features that result in the quietest, safest, and most efficient hovering aircraft of any configuration currently being developed for UAM missions.

These patented features, which allow Jaunt to operate at efficiently low tip speeds compared to conventional designs, include a 70% reduction in main rotor tip speed from hover to cruise flight, a high energy inertia rotor system and a high static thrust scimitar propeller design. In addition, Jaunt provides the safety of a fly-by-wire flight control system and the comfort of Jaunt’s patented LevelFlyTM technology, a mast tilting capability which facilitates management of the aircraft attitude throughout its flight envelope and provides a generous center of gravity (c.g.) envelope.

Additional features of the SRC include design and power management flexibility to meet transportation challenges and fully integrated autonomous flight controls suitable to support FAA flight data acquisition studies.

Jaunt announced it had acquired rights to use the Carter technology at the Vertical Flight Society’s 2019 Autonomous VTOL Technical Meeting and Electric VTOL Symposium.

Jaunt Air Mobility’s Martin Peryea, Chief Technology Officer, stated at the Uber Elevate Summit 2019, that they will be looking to certify their electric compound helicopter with the FAA Part 29 Transport Category Rotorcraft and believes they can get performance Class 1 from their aircraft based on the electric technology for propulsion, it’s unique features, it’s redundancy and the rotor acts as a spare engine, if you will, upon certain engine failures.

As of June 2019, Jaunt Air Mobility’s timeline is for demonstrators are to be built in 2021, FAA Part 27/29 certification is expected to begin in 2022, with production beginning in 2025 and finally, ROSA Next Gen by 2030. Peryea stated their eVTOL aircraft, by definition, is a gyrodyne. A gyrodyne is a rotorcraft and their eVTOL rotor is powered full-time in flight. Peryea feels their aircraft can be certified faster than other eVTOLs because gyrodynes have already have been certified by the FAA in the past.

  1. Is Jaunt going to continue to develop the Carter Copter PAV with a 100LL power plant or are you solely interested in electric power? I have followed the Carter project for years with his slowed rotor concept.
