Swiss company Unmanned Systems is showing a model of its Orca rotary-wing unmanned air vehicle for the first time here at Dubai. The Orca employs a revolutionary tip-jet propulsion method that not only improves performance in many key areas, but also overcomes many of the operational problems encountered with conventional propulsion methods.
China has ordered 250 AI-222-25F turbofans from the Ukraine to power production versions of the Hongdu L-15 advanced jet trainer.
Turbomeca plans to reduce the specific fuel consumption (SFC) of its turboshaft engines by 37 percent by 2030, and at the Helitech 2011 show discussed the strategies it is implementing to accomplish that change. While the company plans to make changes to the engine machinery, it expects much of the reduction to come from engine-airframe integration and new practices that make more efficient use of the engine.
Bombardier’s new Learjet 85 is the latest in a growing line of business jets to feature an integrated air management system from Liebherr-Aerospace & Transportation (Booth No. N5307). The company’s expansion into business aviation is in line with its aim to become the world leader in civil aircraft air systems.
ACES Systems, a division of Technology for Energy Corp. headquartered in Knoxville, Tenn., is at Booth No. N2311 to acquaint NBAA convention-goers with its line of aviation vibration and acoustical analysis and balancing equipment for airframe and engine ground test and test cell applications.
GE is here with three major programs at various stages of development. The Passport 20, for Bombardier’s Global 7000 and 8000 large-cabin business jets, has already passed some rig tests. The GE Honda HF120, for the HondaJet and the (currently suspended) Spectrum Freedom, is scheduled for certification in 2012. Meanwhile, the HF80 turboprop is due for certification later this year.
The AgustaWestland AW189 medium twin helicopter will be the first civil application for Microturbo’s e-APU, an auxiliary power unit that delivers essentially electric power.
Boeing delivered the first 737NG powered by CFM56-7BE turbofans–a 737-800–to China Southern Airlines at Boeing Field in Seattle last week. The new engines, now standard on all new 737s, includes improvements to the high-pressure compressor, a new outlet-guide-vane diffuser, fewer high-pressure-turbine blades and an “optimized” low-pressure turbine.
A second test flight of the X-51A WaveRider has not gone according to plan. Successfully dropped from the left wing of a B-52H Stratofortress, and then accelerated to over Mach 5 by a solid rocket booster, the unmanned, scramjet-powered, hypersonic vehicle crashed in the Pacific Ocean off Point Mugu NAS, Calif. on June 13
EADS has unveiled two new futuristic “Flightpath 2050” aircraft. The Zero Emission Hyper Sonic Transport (ZEHST) would fly above the atmosphere to avoid dumping pollutants in it, except for a relatively small amount during takeoff. The descent would be a unpowered glide, apart from restarting the engines for the final approach and landing. A steep climb on takeoff would leave a relatively small noise footprint around the airport.
