HmHmHm.......Thanks a lot. I confirm that engine is liquid cooling turbocharged R-7755 by Jared-san's book.When I saw Martin model 216-1 flying wing drawing, I had following impression.
(1)Each wing four engine propeller thrust line direction are different. Outer two engine propeller thrust line are almost horizontal, but inner two engine propeller thrust line directed upward.
(2)Engin cooling is by skin cooler? I see many steam cooling channel at wing cross section upper surface.
(3)Engine side round device is turbo supercharger?
(4)Engine intake air outlet nozzle is located wing under surface.
(5)Engine air intake size is very large. Engine is liquid cooling type, but located in air flow. Why?
On (1), could this have been an attempt to deal with CG bombload issues? It would seem that altering the power for the inner, upward-inclined engines could add extra pitch control.
