The newly formed United Technologies’ Advanced Projects (UTAP) division unveiled its initial hybrid-electric demonstration aircraft this morning, which it said will yield 30 percent fuel savings on a typical one-hour mission. Dubbed “Project 804” (P804), the aircraft is expected to fly within three years. It is a reworked Bombardier Dash 8-100 twin turboprop, re-engined on one side with a two megawatt-class propulsion system and an engine optimized for cruise efficiency augmented by a battery-powered electric motor that assists during the 20-minute takeoff and climb sequence.
