Boeing and SkyHook International say the design of the SkyHook Heavy Lift Vehicle (HLV) has reached the configuration freeze milestone, meaning the aircraft's overall performance and layout have been established. Boeing and SkyHook have worked on the SkyHook HLV's structural and systems design and its concept of operations since July 2008, resulting in: the addition of a three-piece tail for enhanced maneuverability; integration of lifting and thrusting propulsion systems; and, improved aerodynamics for increased payload capacity and range. The next major program milestone will be Detailed Design in 2011, which centers on the design, analysis and specification of all hardware, software and related aircraft and ground support systems interfaces. "The SkyHook HLV technology is like nothing that has ever existed. We anticipate that the operational capability of this aircraft will allow SkyHook's customers to radically change the way they resupply and operate in remote regions, especially the north," said Rob Mayfield, director of SkyHook. "In the oil and gas industry, there are significant pressures on cost, speed, safety, and environmental impact, and the SkyHook HLV represents solutions to each of these challenges in various applications." SkyHook is designed to carry 80,000-pound (40-ton) sling loads up to 200 nautical miles without refueling - a capability that is not currently available, but is desired by several industries, including oil exploration and mining operations in the Canadian Arctic and Alaska, as well as companies operating in remote locations in South America, Europe and Africa. Boeing is designing and will fabricate a production SkyHook HLV prototype at its Rotorcraft Systems facility in Ridley Park, PA. The new aircraft will enter commercial service after it is certified by Transport Canada and the FAA. The first SkyHook HLV aircraft is scheduled to fly in 2014. SkyHook International is a privately owned company located in Calgary, Alberta, Canada.
