Such planes may not be flying for another five or 10 years, but aeronautical engineers declared that they would be practical. "The bigger you build them the more efficient they are," one engineer The Air Corps is now completing at Wright Field, Dayton, Ohio. a power factory laboratory designed to test engines up to 8,000 horse powe: using propellers 40 feet in diameter The largest present twin-row, air-cooled engines develop a maximum of 2,000 horsepower and the average motor car engine rates less than 100 horsepower. The largest propeller blades now in use on large bombers or transport planes are about 16 feet in diameter.
The largest planes flying today are land and sea machines weighing a maximum of 50 tons. They are capable of flying 2000 miles at a cruising speed of 130 miles an hour, Pan-American Airways recently asked for designs for 65-ton planes capable of flying across the Atlantic and back again without a stop—Reuter.
