XTI Aircraft TriFan 600

Using three ducted fans, the TriFan 600 lifts off vertically and in seconds the two wing fans rotate forward for a seamless transition to high-speed flight. Within just 90 seconds, the airplane reaches cruise speed — where the lift is provided by the wings just like every other fixed-wing airplane. The fuselage-mounted fan, no longer needed, closes up. The airplane flies directly to its destination and reverses the process. Landing vertically right where it needs to be — wherever there’s a clear helipad-sized paved surface.

XTI Aircraft unveiled its TriFan 600 in August 2015 with a well-publicized equity crowdfunding (see “Industry Briefs,” Vertiflite, Nov/Dec 2015). The six-seat, fixed-wing airplane uses three ducted fans to power the aircraft from vertical takeoff and landing to 340 kt (630 km/h) and a range of 650 nm for VTOL or 1,200 nm (2,222 km). The company is currently testing a 65%-scale technology demonstrator powered by a single HTS900 turboshaft engine with first flight conducted on May 2, 2019. A full-sized prototype is planned for 2020.

The new XTI chief executive Bob LaBelle, formerly the CEO of AgustaWestland North America, announced in the March/April 2017 issue of Vertiflite that the TriFan 600 would feature a hybrid-electric drive system. Additionally, it was announced Trek Aerospace would partner on this project, providing top-of-the-line fans, extending the aircraft's maximum range and increasing endurance.

XTI Aircraft's first test flight of its 65% scale prototype of the TriFan 600 VTOL aircraft (unmanned and tethered) took place on Thursday, May 2, 2019 around 6:00 p.m. at the Placerville Airport in Placerville, California, USA. The test flights continued through May 3rd with multiple controlled takeoffs, hovers and landings which tested and validated the electric motors, battery power system, ducted fan propulsion flight controls and other electrical systems and instrumentation. The company released a short video with footage of the demonstrator assembly and hover testing.
