Bombardier's Learjet 85 is redefining the midsize market segment by introducing their first-ever all-composite structure. The new material significantly enhances both performance and passenger comfort by allowing greater cabin capacity and reduced drag.

Outstanding strength-to-weight ratio, reduced maintenance, and extended service life are but a few advantages of the all-composite airframe. Carbon fibre has also been proven to offer superior aerodynamics due to its smoothness. The clean-sheet Learjet 85 is expected to hit a high-speed cruise of Mach 0.82, and a transcontinental range of up to 5,556 km, allowing long trips from New York to London and London to Moscow.

"The Learjet 85 aircraft's cabin features more volume and comfort than any exisiting midsize," says Steve Ridolfi, president of Bombardier Business Aircraft. The jet's 19-cubic metre cabin carries eight passengers, with plenty of space for standing or sleeping. Learjet 85's 180 cm high ceiling affords ample headroom when walking, and all eight seats are fully berthable, allowing for natural, recumbent resting positions.

The interior is 10 percent wider and 4.4 percent taller than the Citation Sovereign. In total, the Learjet 85 has 12 percent more cabin volume than the Hawker 900XP, and 21 percent more than the Citation Sovereign. Large windows, measuring about 30.5 by 40.6 cm drench the sleek interior with light and increase the sense of spaciousness. The double-club floorplan includes 76 cm pitch between seats, a roomy lavatory, full service galley, and three storage closets providing in flight access to .85 cubic metres of storage space.

Comfort is coupled with power and reliability in the Learjet 85. Inside are two Pratt & Whitney PW207B engines delivering 27,669 kg of take-off thrust. Recent developments from Pratt and Whitney's engines make the PW207B a cost-saving and environmentally responsible choice. The TALONTM low-emissions combuster and high-pressure turbine disks yield improved efficiency.

Meanwhile, on the outside, the composite body resists corrosion and fatigue that make metal vulnerable. In order to give their customers a fuller picture of the new design's long-term performance, Bombardier plans to complete all fatigue testing for determination of the Learjet 85's full airframe fatigue life by the time it is certified. Many manufacturers only certify to a short initial fatigue life, then pursue additional long-term testing after certification. The Learjet 85 is also sturdier thanks to a reduced structural part count. A typical metal Learjet is comprised of 14,000 parts. The composite Learjet 85 will have only about 1,000 parts.

Bombardier's new jet is customer driven, a clean-sheet design, and positioned between the midsize Learjet 60 XR aircraft and the super-midsize Challenger 300 jet. The company has hired Switzerland's Grob Aerospace to help build the aircraft prototypes, contributing world-renowned experience in developing composite aircraft structures. Wind tunnel tests were underway last spring and several orders have already been received.
