Physical Aerodynamicists are responsible for designing and testing aerodynamic surfaces, such as wings and airfoils. They use their knowledge of fluid dynamics to predict how these surfaces will behave in different flight conditions. Their work is essential for the development of new aircraft and other vehicles that rely on aerodynamic lift.

1. Design and Analysis of Aerodynamic Surfaces

Physical Aerodynamicists use computer-aided design (CAD) software to create 3D models of aerodynamic surfaces. They then use computational fluid dynamics (CFD) software to simulate the flow of air over these surfaces. This allows them to predict the aerodynamic forces and moments that will be generated by the surfaces.

2. Wind Tunnel Testing

Physical Aerodynamicists also conduct wind tunnel testing to validate their CFD simulations. Wind tunnel testing involves placing a model of the aerodynamic surface in a controlled environment and measuring the forces and moments that are generated by the flow of air over the surface.

3. Data Analysis and Interpretation

Physical Aerodynamicists analyze the data from CFD simulations and wind tunnel testing to identify areas of improvement. They may also use this data to develop new aerodynamic designs.

4. Collaboration with Other Engineers

Physical Aerodynamicists often work with other engineers, such as structural engineers and propulsion engineers, to ensure that their designs are feasible and meet the required performance specifications.

To prepare for an interview for a Physical Aerodynamicist position, it is important to have a strong understanding of the following key concepts:

1. Fluid Dynamics

Fluid dynamics is the study of the flow of fluids, such as air and water. Physical Aerodynamicists need to have a strong understanding of fluid dynamics in order to predict how aerodynamic surfaces will behave in different flight conditions.

2. Aerodynamics

Aerodynamics is the study of the forces and moments that are generated by the flow of air over objects. Physical Aerodynamicists need to have a strong understanding of aerodynamics in order to design aerodynamic surfaces that will generate the desired aerodynamic forces and moments.

3. Computational Fluid Dynamics (CFD)

CFD is a computer-based technique that is used to simulate the flow of air over aerodynamic surfaces. Physical Aerodynamicists use CFD to predict the aerodynamic forces and moments that will be generated by these surfaces.

4. Wind Tunnel Testing

Wind tunnel testing is a physical testing technique that is used to validate CFD simulations. Physical Aerodynamicists use wind tunnel testing to measure the forces and moments that are generated by the flow of air over aerodynamic surfaces.
