Curtiss P-36, Hawk 75 and XP-42
« on: August 09, 2012, 06:12:59 AM »
Open cockpit with small fairing for pilot's head
Revised tail surface to look more like those of the P-6E, etc.
Squared off main wing tips.
Fabric main wings...outer portion only much like that of the early F4U.
Retractable gear kept.   
-----------------------------------------------------
The P-36 is used for Lend Lease
Re engined with a cowling similar to the I-16.

Poor P-36s.  Ignored and unappreciated.
This be their opportunity to be recognized.

On my site http://www.kristofmeunier.fr/twin_boom_whatif_1939_45.htm there are zwillings P-36+40 and P-36+42, celebrating the 36...

Just a thought, how about a "very-late-model" P-36 with a R2600 or R2800 mated to a P-40N fuselage and wings?  If that has weight and balance problems, use the lengthened fuselage of a P-40K/L instead.

For that matter, how about a P-36 with an engine upgrade and P-40E wings?

I had a quick look through the reports but didn't see if these test were related with the new jet fighters that were coming on line about then. Would you know why they were testing this type of tail Jon ?

The first line in the advance report:
The NACA is conducting flight tests of an all-movable horizontal tail installed on a Curtiss XP-42 air-
plane because of its possible advantages as a longitudinal control for flight at high Mach numbers.

The NACA's research of this sort was general rather than specific, and as the program started during
the war it's doubtful it had anything to do with any particular design, and probably there wasn't any
likelihood of incorporation into existing jet fighter designs, but the results were possibly used
during X-2 development.

Thanks Jon, I did read that but didn't make a connection. I have read a lot about RAE doing various tests because the RAF's aircraft were getting to the critical point, which was called 'compressibility' back then IIRC.
