Transcend is developing the Vy 400 family as a fly-by-wire tiltwing turbine-powered aircraft, offering greater range and speed than helicopters. The company says the aircraft will deliver per mile direct operating costs that are one-quarter of those for medium-sized, twin-engine helicopters with comparable cabin volumes and payloads. It is intended for scheduled regional services of up to 450 miles, with operations projected to begin in 2025.

In December 2019, the company was already taking orders for its initial Vy 400R model, and at the end of 2020 it opened the order book for the later Vy 400 model with a projected purchase price of $3.5 million. On December 5, Transcend announced a partnership with aircraft interior designer Huslig Collective to develop luxury interiors for the Vy 400R "Reserved Edition" aircraft.

In early January 2020, Transcend said that it had completed the design for a new propeller, which it says is around 25 percent quieter due to its reduced tip speed. Following simulated performance tests, the company reported speeds of 363 knots (418 mph). 

U.S. air taxi operator Hopscotch Air has expressed an interest in operating the Vy 400 aircraft. In September 2020, company founder Andrew Schmertz told Business Insider he views Transcend's eVTOL concept as a next step from the Cirrus SR-20/22 aircraft it currently operates.

On April 5, 2021, the company announced that it had been awarded a small business technology transfer research and development contract by the U.S. Air Force AFWERX program to develop the Vy 400 for military support missions. According to COO Peter Schmidt, throughout 2020 and into 2021, the company has continued to advance engineering work on the aircraft using a mixture of simulation, analysis tools, and truck-based testing to refine flight control laws, handling qualities, and various systems details. He told FutureFlight that, under the direction of chief engineer Cliff Gunsallus, Transcend remains on track to meet its certification and entry into service target of 2025.

In February 2022, Transcend announced plans for two possible military versions of the aircraft that are among 11 programs now being evaluated by the U.S. Afwerx agency's High-Speed Vertical Takeoff and Landing (HSTVOL) Concept Challenge. The V-500 Catamount is based on the Vy 400 passenger transport with a more powerful GE T901 turboshaft engine and new higher-speed propellers to support a possible 720-mile combat radius at speeds of 500 mph. An alternative V-400 model with a GE CT7-8 engine is also being considered. The Afwerx teams is evaluating HSTVOL aircraft options for a variety of military missions for both the U.S. Air Force and Special Operations Command.

Outlook

Our objective assessment of this program’s probable success.

FutureFlight assesses the probability of success for a new aircraft program by considering the following criteria:

  • Total investment funds available in proportion to the anticipated cost of getting an aircraft certified and in service
  • A company’s in-house capability (in terms of numbers of engineers, technical staff, and customer support teams)
  • The past experience of the company and its senior leadership in developing aircraft
  • The caliber and past experience of key program partners
  • Whether key aircraft systems have been selected and are available for use
  • Whether the preliminary design review has been completed
  • Whether the design for the full-scale prototype has been completed
  • Whether the type certification process has been formally initiated with an appropriate regulator
  • Whether the company has achieved a first flight with a full-scale prototype
  • The number of hours logged in a flight test program
  • Whether type certification has been achieved
  • The number of orders and commitment received for the aircraft
  • Whether the company has adequate facilities to begin series production of the aircraft
Our Methodology

As of June 2020, Transcend's management team said that the company intends to complete type certification for its Vy 400R and Vy 400 aircraft in partnership with an established airframe.  To date, the program has operated as a research and development organization that has achieved the preliminary design phases, the building of multiple 1:5 scale flying prototypes, and full-scale simulation. The Vy 400 has passed five external design reviews. Seed funding for the company has so far, reportedly, raised more than $2 million.  

Transcend's choice of a conventional turboprop engine as the sole power source significantly reduces the level of technology risk for the program. Also, Transcend appears to intend for the aircraft to be piloted, initially. That said, the company's flying 1:5 scale prototypes are already autonomous and the certified aircraft will be capable of autonomous operation should customer demand evolve to the point where certifying it for remote and/or unpiloted operations deliver a return on the additional certification costs.

The Vy400's configuration also allows for the turbine propulsion system to be replaced with an electric motor when battery capacity evolves to meet the aircraft's mission demands. 

The program was boosted by a U.S. Air Force research and development contract awarded in April 2021. This support, and the potential for military sales, was further enhanced by the February 2022 announcement that its proposed V-500 model has been shortlisted for the U.S. Air Force' Afwerx program's High-Speed Vertical Takeoff and Landing (HSTVOL) Concept Challenge.

The Vy 400 is a tiltwing aircraft powered by a single 1,700 shp Pratt & Whitney Canada PT6A engine. It will offer a longer range and greater speed than conventional helicopters. In January 2020, Transcend said it had completed design of a new propeller. From simulated performance testing, this is expected to deliver cruise speeds of around 418 mph.

According to Transcend, it will also feature geofencing technology and sensors to allow it to safely avoid flight into terrain. Further safety protection will be provided by a BRS Aerospace whole airframe parachute. It will also be certified to fly into known icing conditions.

The Vy 400R Reserved Edition will feature a luxury cabin interior designed for Transcend Air by interior designer Huslig Collective. Transcend began taking orders in December 2019 and does not expect to offer the Vy 400 version until the end of 2021. The Vy 400R model is priced at $6 million.
