Vy 400 (defunct)
Transcend Air Corporation
Carlisle, Massachusetts, USA
The Transcend Air Corporation was founded in 2017 in Carlisle, Massachusetts, USA. The company is in the business to design and manufacture tilt-wing hybrid-electric vertical takeoff and landing (VTOL) passenger aircraft for efficient and low cost city to city advanced air mobility (AAM) travel for the VIP traveler. As the aircraft can takeoff and land on any landing pad, airport tarmac, parking lot or grassy area, the aircraft will whisk the traveler to the destination faster than traditional airport-to-airport flying. Their aircraft can also fly its passengers to their destinations faster than a helicopter, according to the company.
Vy 400 hybrid-electric VTOL passenger defunct aircraft
The Vy 400 is a hybrid-electric VTOL passenger aircraft (and now defunct as of August 2023) which has one pilot and can carry up to five passengers. The estimated cruise speed is 410 mph (660 km/h) and a range of 500 miles (804 km). The aircraft has a payload of 2,190 lb (993 kg). The aircraft can have a longer range with fewer passengers and less seating. According to the company, when GE makes the next version of the same turbine engine they plan to use, which will have more horsepower, the range of the aircraft will be increased another 125 miles (161 kg). A safety feature includes an emergency whole aircraft parachute.
The Vy 400 has one main tilting wing with one propeller at the end of each wingtip. Each propeller is turned by electric motors and the electricity made for the entire aircraft is by a 2,500 hp GE CT7-8 turbine engine. The aircraft also employs a collective and a 30 kW electric stationary VTOL propeller prop in the rear of the aircraft. The aircraft uses Geofencing plus sensors to avoid obstacles.
In November 2018 Transcend Air selected VerdeGo Aero to provide the hybrid electric propulsion systems for an expanding family of Vy aircraft after the turbine Vy 400 has matured.
City routes examples
The company plans to establish a short-haul air service in 46 cities and here is an example of some of the city routes: Boston - New York - Washington D.C., San Francisco - Los Angeles – San Diego and/or Montreal – Toronto. The company has stated they plan to land on purpose built sustainable, zero-emission barge-based landing spots, called vertipads, and possibly land and take off from existing helipads.
Prototype flight testing
In September 2018, two electric-powered, one-fifth-scale prototypes began flight tests to evaluate vertical and forward flight transition. These will be followed by a half-scale prototype powered by a smaller PT6A engine to demonstrate the drive train. As of January 2019, assuming a successful Series A round funding round, the first flight of a full-scale manned prototype is expected in 2021.
The Vy 400 is based on a long line of flying VTOL prototypes from as far back as 2009, including the 1,984 lb (900 kg) crewed Elytron Converticopter. Transcend Air Corporation estimates as of September 2021, that the a Vy 400 will be priced between $4.6 to $6 million. At the time, the company hoped to have the Vy 400 passenger aircraft certified by 2025.
