Force and moment balances have served as the most direct tool for determining these qualities. The aerodynamic forces and moments experienced by a vehicle in its operating condition are often of crucial interest to aerodynamicists. Although we live in an era of sophisticated computer simulation, aerospace engineers continue to depend on the testing of physical models to validate computer data and establish baseline aerodynamic knowledge.

It has resulted in many useful ways of dealing with the lack of their replication of on-road conditions.Īs a result, wind tunnel assessments are critical in the aerospace industry since the physics of flight is dependent on the correct flow of air to generate lift and decrease drag. This has been extensively studied for many years and continues to be an area of enduring interest. Where differences exist between wind tunnel and road, it is important to know how they influence the results that rate generated by wind tunnel testing. Likewise, the test-section flow velocity (around a stationary vehicle) attempts to re-create the relative motion between a moving vehicle and the surrounding (stagnant) environment. When air flows over or around a test model, whether it is fixed or dynamic, wind tunnels may offer valuable information into the impacts of the air on the model. In many sectors, wind tunnel testing is a necessary component of the design and development process. For example, in a wind tunnel, both the far-field boundary and the ground boundary are represented in some convenient and yet useful manner. However, the aerodynamics generates in a wind tunnel is not identical, but merely equivalent (to some degree) to the aerodynamic experienced “on-road”. Wind tunnels, in the broadest sense, try to simulate the aerodynamic conditions that a vehicle would experience in its operating environment. The primary list facility is the wind tunnel. Aerodynamic development is done almost entirely experimentally, guided by empiricism based on the experience.
