It takes a very special engine to power an aircraft as unique as the XTI TriFan 600. That engine is the Honeywell HTS900 turboshaft, the leader in its class when it comes to fuel efficiency, power-to-weight ratio, reliability and cost of maintenance.
Just one HTS900 engine will drive the three fans on the TriFan 600, the world’s first hybrid-electric vertical takeoff and landing business aircraft.
An HTS900 mockup and a TriFan 600 model will be on display at the XTI exhibit (Central Hall, C9020) at this year’s National Business Aircraft Association (NBAA) Show and Convention in Las Vegas (Oct. 10-12). Visitors will also want to see the full range of Honeywell’s Connected Aircraft products, services and software solutions at North Hall – N5100.
The TriFan 600 is a six-seat aircraft that will have the speed, range and comfort of a business jet and the ability to take off and land vertically, like a helicopter. Using three ducted fans, the TriFan 600 lifts off vertically and its two wing fans rotate forward for a seamless transition to cruise speed, at 300 miles an hour and a range of up to 1,100 miles. XTI plans to fly a demonstrator in 2018.
Honeywell’s HTS900 will enable the XTI TriFan to fly efficiently for long distances with heavy loads. It’s the latest engine in Honeywell’s highly successful family of turboshaft engines, which have been providing power when it counts for more than six decades. Thanks to next-generation technologies, the HTS900 offers the best performance in its class.
It features a dual centrifugal compressor, cooled turbine blades and nozzles and a dual channel FADEC, all of which results in an output of 1,021 shaft horsepower; a significant increase in power output at high/hot conditions over rival engines in this class; all while burning less fuel and occupying less space.
The HTS900 is meeting high expectations on the Eagle 407HP program. Using design and engineering licensed from Bell Helicopter, Honeywell and Eagle Copters are improving the performance of existing Bell 407 helicopters by replacing the standard engine with the HTS900. Ten helicopters have been converted so far.
