Some shots from our ramp today
The DC-4 was the first of the Douglas 4 engine airplanes. It used the PW-2000 engine which was for its time fairly reliable. Douglas followed the -4 with the DC-6 which used the reliable R-2800 engine and it had a 3 blade prop. Thus it was referred to as the best 4 engine airplane with 3 blades. The -7 used the -3350 which was an engine that gave operators more than a few problems and it had a 4 blade prop. Putting out about 1hp per inch, the -3350 was used on the B-29 and the B-32 and for a while, more B-29s were being lost to engine fires and engine problems than enemy action.They lacked the ability to count?
Whoa..... Nice information.The -7 was THE competition for the Connie and what some don't know is the designs for the DC-4 and the Connie were in the competition that was won by the Boeing B-29. Douglas and Lockheed dropped out and Boeing won. Consolidated Vultee was chosen by default to produce a 'back-up' much like the Germans built the FW-190 as a back-up for the Me-109. But the Convair backup, the B-32 never gained any fame and only a few were produced.
Although the -32 flew about the same time as the -29, it didn't reach any production numbers until the -29 had been used and thus many innovations such as the computer controlled gun turrets and the pressurization system were deleted on the -32. FWIW, the last combat sortie in the Pacific was a B-32.
But back to the -7 and the Connie.. the Connie also used the -3350 and although the -7 was slightly faster, the Connie had longer range.
The beauties were the Super G flown by TWA and the 1649 which was the one with the long thin wing. And then there was the "Elation" which was used in the USAF and the USN. The 'Elation' was the military Connie that had turboprops instead of big recips.
