The Transcend Air Vy 400 is a tiltwing convertible aircraft developed by American startup Transcend Air.

Development

In September 2018, Transcend was flying two electric-powered, one-fifth-scale prototypes to evaluate aerodynamics of the vertical and forward flight transition. It should be followed by a half-scale prototype powered by a smaller PT6 to demonstrate the drive train. A 2019 Series A round would fund a full-scale manned prototype flying in 18–24 months, for a 2023 end certification. A manufacturing partner is sought to certify the aircraft for $350–500 million and produce it. [1] By November 2018, Transcend had selected VerdeGo Aero to provide hybrid electric propulsion systems after the turbine version. [2]

Transcend Air is based in Boston and led by Gregory Bruell, co-founder of VTOL developer Elytron Aircraft, and Peter Schmidt, former head of air-taxi Linear Air. [1]

The company wants to establish a short-haul scheduled airline between barges in 46 cities like Boston-New York/Washington, San Francisco-Los Angeles/San Diego or Montreal-Toronto, for less door-to-door cost than the combined cost of existing airlines plus ground transport while avoiding paying for an empty re-positioning leg like air charters, but is skeptical about the on-demand model behind urban air mobility. [1]

Design

Being half the size of the Leonardo AW609 tiltrotor, it would be certified under the FAR Part 23 commuter category, with industry standards for compliance and elements of helicopters FAR Part 27. Steep approaches and departures would minimize noise and airspace issues. [1]

Its single 1,700 hp (1,300 kW) Pratt & Whitney Canada PT6-67F turboshaft from the drives wingtip proprotors via gearboxes and shafts, with collective and a 40 hp (30 kW) electric tail fan for flight controls with fly-by-wire envelope protection. The cabin is larger than a high-performance turboprop single like the TBM 930 with 23 in (580 mm) wide seats and enough leg room for 6 ft (1.8 m) tall passengers, and it would have landing skids not wheels. [1]

With a maximum takeoff weight of 6,990 lb (3,170 kg) and a useful load of 2,200 lb (1,000 kg) for fuel and a payload of five 200 lb (91 kg) passengers with overnight bags, its range would be 450 mi (390 nmi; 720 km) at 405 mph (352 kn; 652 km/h). It would be sold for $3.5 million like a Bell 407GXP light helicopter but costs per mile will be halved: hourly costs are 50% higher but it is three times faster. A larger and higher-performance Airbus AS-365N3+ helicopter is slower and more expensive at $10 million. [1]

The Bell X-22 is an American V/STOL X-plane with four tilting ducted fans. Takeoff was to selectively occur either with the propellers tilted vertically upwards, or on a short runway with the nacelles tilted forward at approximately 45°. Additionally, the X-22 was to provide more insight into the tactical application of vertical takeoff troop transporters such as the preceding Hiller X-18 and the X-22's successor, the Bell XV-15. Another program requirement was a true airspeed in level flight of at least 525 km/h.

An XC-142A first flew conventionally on 29 September 1964, and on 11 January 1965, it completed its first transitional flight by taking off vertically, changing to forward flight and finally landing vertically. Its service sponsors pulled out of the program one by one, and it eventually ended due to a lack of interest after demonstrating its capabilities successfully.

The Urban Aeronautics X-Hawk is a proposed flying car designed by Rafi Yoeli in Yavne, Israel, being built by Metro Skyways Ltd., a subsidiary of Yoeli's privately held company, Urban Aeronautics. The firm claims to have flown the car to a height of 90 cm (3 ft), and that greater heights are possible. The X-Hawk and its smaller unmanned version, the Tactical Robotics Cormorant, would be used in search and rescue operations where a helicopter would be useless, or at least very dangerous, such as evacuating people from the upper stories of burning buildings, or delivering and extracting police and soldiers while very close to structures, narrow streets, and confined spaces, with a projected size similar to that of a large van.
