The XP-83 Airacomet II would also have been a good design to develop.
I just discovered a plane built by HenriConada in 1910 that used jet propultion! Albeit a motorjet, this design was 30 years ahead of its time. Its a shame no one took financial intret in this venture. Still, it was the first designed and built manned jet aircraft and it even took to the air, though this occurnce was accedental and unfortunately resulted in the distruction of the aircraft.
also a pipe dream....the p40 airframe with the merlin engine, just see what the merlin did for the mustang
Errrm, not actually a pipe dream, as they did operate with Merlins. Of the 13,740 or so built, just over 2,000 operated with Merlin engines.
The P-40F and P-40L both flew with Packard Merlin V-1650-1 engine, essentially a licence built copy of the Merlin 28 engine, but built to US tooling measurements and featuring US carburettors and some other detail improvements (as well as a tendency to leak oil).
Performance at atitude was better than with the Allison, but not spectacularly so. P-40Fs topped out at about 365 mph at 20,000 ft, and the lighter P-40Ls about 5 mph faster. Compare this to the 360 mph at 15,000 feet of the P-40D/E and, while better, its not anything to write home about.**
Most P-40Fs unded up serving with the Soviet Union, but 300 or so served with the RAF, RAAF and SAAF.
The fundamental difference between the P-40 experience and the P-51 experience is that while the P-40 swapped its single stage, single speed Allison for a similarly powerful single stage two speed Merlin 28/V-1650-1 engine, the P-51 swapped its single stage, single speed Allision for a more powerful two stage, two speed Merlin 60 family engine.
Some 300 P-40L/Fs were converted back to Allison engines, because of the lack of Packard Merlin engines and spare parts, and their incompatability with the British/Commonwealth supply train (requiring slightly different sized tools and such to work on).
**Just looking through some war time test data, and it seems the RAAF had a hard time getting any speeds above 350 mph out of its P-40Es, even with the Allsions cranked up at the 57" War Emergency Rating. To be fair though, their P-40Fs were 5-10 mph down on their nominal tested speed as well.
Seems to be a common thread with RAAF tests. The P-30F they tested was about 15 mph down on advertised top speed, while their Spitfire Mk VIIIs was about 10 mph slower than given nominal. Might of been something to do with the atmospheric conditions the tests were conducted in.
