KEEPING KOOL – December 7, 2018
Our radiator space is limited, and one way to handle that is to make the radiators deeper than the standard found in automotive uses. Although our worst case will probably be an automobile traffic stop-and-go scenario, we want the radiators to be efficient and effective while driving and flying.
This meant providing a clean path of air through the radiators and having an area of low pressure for the exiting radiator airflow to exit through. To choose this clean air path, we used a surface pressure map determined through Computational Fluid Dynamics (CFD) produced years ago by DAR Corp, in Lawrence, Kansas. This CFD is like a wind tunnel in a computer and can give you low and high-pressure zones around the surface of the body at different angles of attack.
We are now creating the duct for the radiators, oil cooler, and turbo inter-cooler. You can see these parts all lined up and ready, in the image above.
