While this example is specific to aircraft design, analytical models are useful in all engineering and scientific disciplines –for example, they can be used to model drug interactions in biological systems, or to model pumps, compressors, and other mechanical and electrical systems. We will then use the data management and analysis tools in MATLAB ® to simulate the models for different scenarios to verify that anticipated bending moments are within design limits. We will derive the models in the notebook interface in Symbolic Math Toolbox ™.

To accomplish the objective, a two-dimensional wind tunnel test of. The target pressure is specified and a least-squares optimization is used to minimize the pressure. The Navier-Stokes equations can include the rotational viscous physics at transonic speeds, and hence are expected to produce more reliable designs. In addition, the airfoils maximum lift-to-drag ratio was designed to occur at a high lift coefficient. The feasibility of the use of the Navier-Stokes equations in aerodynamic design is examined. In this article, we will derive analytical models of the loads and bending moments on the wing of a small passenger aircraft to determine whether the wing design meets strength requirements. The 24 percent thick S814 airfoil was designed with these characteristics to accommodate aerodynamic and structural considerations for the root region of a wind-turbine blade. Analytical models can help because they describe systems using mathematical equations, showing exactly how different parameters affect system behavior.

When modeling engineering systems, it can be difficult to identify the key parameters driving system behavior because they are often buried deep within the model. The resulting airfoil has a maximum lift coefficient of 2.5 at a designed Reynolds number of 300,000 and shows that aft loading on an airfoil is conducive to high-downforce requirements and is a favorable design direction when considering airfoils for race car wing applications.
