  5. 5. vation in aviation page 49 i T has been moRe Than 10 years since a new Learjet platform was introduced to the general aviation market. Now, Bombardier has unveiled details of its forthcoming Learjet 85 that promises to fly faster and further than any of its predecessors - and its flawless design is fused with the latest technologies on the market. Upon its highly anticipated release in 2013, the Learjet 85 will be the first mid-range business jet to be built primarily from carbon composites and designed for type certification under the US Federal Aviation Regulation. Ralph Acs, Vice-President of Learjet 85 at Bombardier Business Aircraft believes the company’s ‘clean-sheet’ approach of replacing traditional aluminium structures with carbon fibre composites will revolutionise the industry. Acs says: “Sometimes you may need three or more parts if you are constructing something out of metal and then you have to fasten parts together. With February 2011

In a metallic aircraft, this part would be made out of hundreds of pieces but with the carbon fibre design it is a single piece.

You design it, make it, tweak it and then try it all over again. In the end, what we want is a simple and repeatable manufacturing process.” The ability to design a structure with fewer parts and fasteners helps reduce unit costs, which has been a key February 2011

The Learjet 85 cabin provides a larger and more comfortable space than current jets in the mid-size market. Consisting of 14 large ralph Acs windows, the cabin has a maximum height of 5ft 11 inches and a maximum width of 6ft 1inch. The aircraft, with a maximum capacity for eight passengers and two crew members, is fitted with the latest technology and some great luxuries. “From nose to tail, the Learjet 85 aircraft remains true to Learjet’s commitment to innovation by integrating the latest in technological advances with superior design aesthetic,” says Acs. “The aircraft features the latest technology in its advanced entertainment system, which offers passengers February 2011

The lower the cabin altitude that the person is feeling, the more rested and comfortable they will feel at the end of the journey,” says Acs. I guess we will all buy that. md the cabin layout of the learjet 85 provides a larger and more comfortable space than current jets in the mid-size market February 2011
