Information of TTFLY: XTI Aircraft has picked Honeywell International's Aerospace division to supply its HTS900 engine for use in XTI's first prototype of the TriFran 600 vertical takeoff and landing airplane. Honeywell will also provide an additional engine for use in XTI's Ground Propulsion Test System.

XTI will build an operational propulsion jet stand that will house the Honeywell engine, drive train system, fans and flight controls. XTI will then complete development of the two-thirds piloted flying prototype.

The announcement follows an earlier one in which XTI said it would reopen its call for investments in the TriFan. The startup previously refunded more than $1.2 million in investments it had garnered through a crowdfunding campaign after it had failed to reach its self-proclaimed $3 million milestone by April 30.
