Good evening gentlemen.
In response to your questions re. the Republic P450:
The scant information about it is an article in a 60s magazine about the development of the P47.
Republic designed a jet-propelled version named the P450. It was a simple matter to remove the radial engine and replace it with an intake duct leading to the turbojet. The high cockpit meant that the intake air could easily be directed beneath the cockpit to the engine. The rear centre of gravity resulted in the retention of the tailwheel.
I then searched the net for a drawing. This may be found by proceeding as follows:
1. Google images "Republic P47 jet airplane"
2. go to page 2
3. 5th from the left on the top line
4. select full size image
I have no information as to whether it flew or not.
If it caused heartache and grief I apologise.
Incidentally,
Noyade is not playing because he is in Canberra for a few days.
I also have had much heartache and grief today trying to teach aerodynamics to a first-year university course....
