DC-8 (piston airliner)
The Douglas DC-8 was a piston-engined airliner project by Douglas Aircraft.
Based on the cancelled XB-42,[1] the program began shortly after the end of World War Two. It was intended to operate on short- and medium-range routes, carrying between 40 and 48 passengers[2] in a then-novel pressurized cabin[3] (which had been pioneered by the Boeing 307 in 1938, but was still not in standard airline use).
The DC-8 was to use the same Allison V1710s as the XB-42[4] (these rated at Template:Convert),[5] fitted below and immediately behind the cockpit.[6] They were to power contra-rotating propellers in the tail,[7] as in the XB-42, by way of driveshafts under the cabin floor[8] (an arrangement reminiscent of the P-39.) Cabin access would have been by airport stair through a single port-side door.[9]
Despite performance predicted to significantly surpass conventional twin airliners[10] excessive complexity and high development costs[11] (with consequent high sales price and operating costs)[12] meant less-risky types, such as Convair's 240 and Martin's 2-0-2 were preferred,[13] and the DC-8 was dropped before a prototype was built.
