The National Research Council Institute for Aerospace Research (NRC-IAR) is pleased to announce that Bombardier* Aerospace chose its 1.5 m trisonic blowdown wind tunnel to test the high-lift aerodynamics of its prototype Learjet 85* aircraft. For over 15 years, the NRC tunnel has been Bombardier’s go-to place for high-lift tests, helping the company develop the high-lift systems for three other aircraft: the Global Express* and Challenger 300* business jets and the CRJ700* regional jet.
The configuration of NRC’s high-speed wind tunnel allows researchers to predict maximum lift and stall characteristics. This information, in turn, helps designers optimize an aircraft's performance, particularly in the takeoff and landing configuration where high lift is required. In addition, the tunnel’s high Reynolds number flow capability makes the facility an ideal tool for improving the aerodynamic performance of business and regional jets.
“We’re pleased that Bombardier Aerospace decided to bring the new Learjet 85 aircraft to NRC for testing because it builds on our past successful collaborations,” says Dr. Steve Zan, Director of the NRC-IAR Aerodynamics Laboratory. “With its high Reynolds number capability, our 1.5 m trisonic blowdown wind tunnel provides a reliable, affordable way to develop regional and business jets. Clients can be confident that what works in the tunnel will work in flight.”
The new Learjet 85 aircraft will be Bombardier Aerospace’s first all-composite structure aircraft, allowing Learjet* designers to maximize cabin comfort while minimizing drag and improving performance. Exceptional strength-to-weight ratio, reduced maintenance and extended service life are key characteristics of all composite airframes, as are the ultra smooth surfaces that permit superior aerodynamics.
The NRC Institute for Aerospace Research is Canada's national aerospace laboratory, undertaking and promoting research and development in support of the Canadian aerospace community, in matters affecting the design, manufacture, performance, use and safety of aerospace vehicles.
Recognized globally for research and innovation, the National Research Council (NRC) is a leader in the development of an innovative, knowledge-based economy for Canada through science and technology.
