Show experts predict P aircraft engines of H P DAYTON omd an horse power engine for or an airplane fantastic not at aall it may be several years away but e army air corps corps research experts at wright field are already looking forward to the he day when airplane power plants delivering four times the power of the big 2000 horse power engines now being tested for the nations newest warplanes war planes will be ready to go on the test stands new power plant test equipment now being assembled at wright field has been designed with this goal in mind and when the big engines are ready as engineers are confident they eventually will be the equipment here will b be a heavy enough and strong enough to perform the necessary tests aviation ja is a young industry less than 40 years old yet in the 37 years since the wright brothers first flight at kittel 1 N C aircraft engines have grown from the small four cylinder water cooled 12 horsepower notor which turned twin propellers on the first plane to the big 18 cylinder cy under 2000 horsepower motors of today and now the wright field power plant laboratory Is working in close cooperation with engine manufacturers to develop a practical 8 horsepower engine and they earnestly believe it can be done present day engine developments are along two lines the radial air cooled type and the liquid cooled type huge frontal areas of the air cooled engines interfered seriously with iclean clean aerodynamic design whereas the liquid cooled engines had tar far less frontal area to buck the airstreams air streams air cooled engine man manufacturers redesigned their engines to meet the challenge until the newest air cooled radial engines provide a diameter not tar far out of line with the of liquid cooled engines of comparable horsepower |
