From the Rolls-Royce experimental archive: a quarter of a million communications from Rolls-Royce, 1906 to 1960's. Documents from the Sir Henry Royce Memorial Foundation (SHRMF).
Graph plotting logarithmic temperature against distance and time to compare cooling performance with various fan, shutter, and louvre configurations.

a = .0990
a = .1445
a = .1540
a = .1660

TO CORRECT FOR FRICTION HEAT, THESE READINGS MUST BE MULTIPLIED BY 1.225

NO FAN COOLING DECREASED 32%
SHUTTERS COOLING INCREASED 7%
LOUVRES COOLING INCREASED 14%

A LATER TEST SHOWS THIS TO BE HIGH
