The aerodynamic design of commercial and business aircrafts requires a careful mix of computational analysis and experimental testing to ensure a timely market delivery at a limited level of risk. Ground test facilities like wind tunnels continue to provide the bulk of experimental data that are used to calibrate CFD codes, validate the aerodynamic design, and generate the aerodynamic database necessary to implement flight control systems. In recent years, market dynamics have provided a strong incentive for aircraft manufacturers to reduce the design cycle time while simultaneously maintain or even reduce the amount of risk associated with aerodynamic design. This is a challenging environment for wind tunnel operators, who are constantly confronted with simultaneous requests for increased efficiency and reduced uncertainty in aerodynamic testing. The present proposal attempts to tackle this issue by looking at different ways that could be devised to improve the accuracy of Bombardier Aerospace's wind tunnel tests. More specifically, the long term goal of the proposed work is the improvement of testing methodologies at two Canadian production wind tunnels regularly used by Bombardier: the 1.5m Trisonic Blowdown Wind Tunnel and the 2m x 3m Low-Speed Wind Tunnel, both located at the NRC Institute of Aerospace Research in Ottawa.

商用飞机的空气动力学设计需要计算分析和实验测试的精心组合，以确保在有限的风险水平下及时交付市场。风洞等地面试验设施继续提供大量的实验数据，这些数据用于校准计算流体动力学代码、验证空气动力学设计和生成实现飞行控制系统所需的空气动力学数据库。近年来，市场动态为飞机制造商提供了一个强大的激励，以减少设计周期时间，同时保持甚至减少与空气动力学设计相关的风险量。这对风洞操作人员来说是一个具有挑战性的环境，他们不断面临着同时提高效率和降低空气动力学测试不确定性的要求。 本提案试图通过研究可以设计的不同方法来解决这个问题，以提高庞巴迪宇航公司风洞测试的准确性。更具体地说，拟议工作的长期目标是改进庞巴迪经常使用的两个加拿大生产风洞的测试方法：1.5米的三音速吹气风洞和2米× 3米的低速风洞，这两个风洞都位于渥太华的NRC航空航天研究所。
