Investigation of 4-engine configurations at NACA Lewis Laboratory showed that aircraft performance gains are possible by applying reheat, regeneration, and combination of the two to turboprop engine; how they compare; at altitude of 30,000 ft, analysis indicates that basic turboprop engine gives greater airplane range than simple turbojet engine up to flight speeds of 400 mph.
