Hello,
I've investigated quite a few reciprocating engine powered and turboprop airplane accidents- as lawn darts colliding with the ground at Warp Factor 50 and gear up landings. Based upon the photographs provided, it's my impression the P-47 was involved in a gear up landing event. Regardless of whether the blades were bent forward due to power (which I've never been able to substantiate during my investigative duties) or not, when the engine is under power, as in a strafing run, after the propeller blades struck the ground, they would be pig-tailed, curled, aft. What I see in the provided photographs is an airplane whose pilot was either unable to extend the landing gear or forgot to do so after a wild sortie that had rattled a tired pilot.
I'm presuming the pilot was operating over relatively level ground and not terrain with numerous mini-hills. If the P-47's belly damage, as illustrated in the photograph, was received during a strafing run, the airplane would most likely have bellied further into the ground, possibly flipped onto its back. Note there's no dirt or vegetation embedded into the belly's deformed aluminum-- whether he hit the top of a little hill or contacted relatively level ground.
Align the belly with the propeller: The available 'clean-blade' on the propeller would be insufficient to provide the necessary thrust for continued flight. The airplane would have been lost and the pilot injured and/or captured if in enemy held territory.
Under a low engine power configuration, as in the touch-down phase of landing, you would see the kind of blade bending shown in the picture- seen it many times. Re-examine the P-47's belly damage... it appears to be low speed caused deformation and twisting resulting, I'd venture to say, from contacting a hard surface runway (because it's clean and scrapped as you see). Had the airplane somehow flown onto the ground as is suggested, the belly damage would be much more pronounced and have earthen residue in it and witness marks on it.
This is my three-cents worth (inflation).
TTFN,
Frank
