Hi People,

May I suggest that anyone that is interested in the subject of the how and why
of the P51 Mustang cooling system go and have a look at the following URLs;  it
might just help to dispell a lot of fuzzy presuppositions and apriori
assumptions:

The following will also assist in clarification of any misconceptions.

If you want to know even more,  the key words for a Google search are "Meredith
Effect" and "Atwood".  Enjoy!!

Interestingly,  there were two other aircraft around that time that used the
same idea with great success:

Both the Martin Baker MB-5 See:

and the local Aussie CAC CA-15 "Kangaroo" used the same principle.

The CA-15 was definitely the fastest - 502 MPH -(and last) piston engined
fighter in the world. Unfortunately,  it just wasn't as fast as the emerging
jet technology,  and the CAC (Commonwealth Aircraft Corporation) ended up
building the mighty Avon Sabre for the RAAF.

Unfortunately.  only one CA-15 was ever made,  and sadly, mulitple acts of
serial bastardry by our wonderful aviation bureaucrats at the time saw it
reduced to a pile of parts instead of being carefully preserved as a monument
to our wonderful aero designers,  engineers and LAME tradesmen.
