Flight tests of exhaust-gas jet propulsion / by Benjamin Pinkel and L. Richard Turner.
Flight tests were conducted on the XP-41 airplane, equipped with a Pratt & Whitney R-1830-19, 14-cylinder, air-cooled engine, to determine the increase in flight speed obtainable by the use of individual exhaust stacks directed rearwardly to obtain exhaust-gas thrust. Speed increases up to 18 mi...

| Summary: | Flight tests were conducted on the XP-41 airplane, equipped with a Pratt & Whitney R-1830-19, 14-cylinder, air-cooled engine, to determine the increase in flight speed obtainable by the use of individual exhaust stacks directed rearwardly to obtain exhaust-gas thrust. Speed increases up to 18 miles per hour at 20,000 feet altitude were obtained using stacks having an exit area of 3.42 square inches for each cylinder. A slight increase in engine power and decrease in cylinder temperature at a given manifold pressure were obtained with the individual stacks as compared with a collector-ring installation. Exhaust-flame visibility was quite low, particularly in the rich range of fuel-air ratios. |
