Radial vs in-line engines

[Crumpp]

why you're taking supersonic aerodynamics and compressibility into the equation?

Well, that is what the report is talking about, Sternjager. Let me know when you have read through it.

Understand too, just because the flow is supersonic does not mean the aircraft is supersonic.....

My point was that if compared to other radiators of the era, the Mustang one was by far the more aerodynamically efficient, and surely superior to radial engines.

On the whole, the Mustang radiator is not so aerodynamically efficient. The duct design is poor at best.

So you're now telling me that the Mustang wing is not a laminar design?

No, I said the Mustang did not achieve laminar flow. That is not the same thing as "designed for laminar flow."

It was designed for laminar flow just as it was designed to achieve the Meredith effect, neither of which occurred.
