II Airplane Engine on Diesel Plan Perfected by American Inventor NEW mw YORK Jan 7 AP AP-An- AP An Announcement by Dr Dl Elmer A. A Sperry that he has perfected an airplane engine on the Diesel principle prin prin- ciple was hailed in aeronautical circles today as ns a a. victory for AmerIcan American AmerIcan Amer Amer- ican Dr Sperry Inventor of the tile gyroscope gyro gyro- scope COlli compass pass said that within a acar year car he expected to have a sotor of 1000 1009 horsepower weighing two pounds T Ier er r horsepower and IO coa- coa l suming crude oil instead of gasoline gasoline gaso gaso- line with a higher power development development develop develop- ment per pr gallon Jallon at one fifth the fuel cost I Adoption of the Direl to aircraft considered one of ot he surest steps to huge air all lin liners rs has been Leen the problem of 01 aeronautical engineering throughout th the world The Diesel motor differs from the ordinary gasoline engine In that there is no spark and that crude oil is used in place of gasoline thus eliminating the fire ha hazard ard The fuel oil used in his en engine lne said Dr Sperry is is' isso so noninflammable noninflammable mable that in experiments it even has proven a a. good fire extinguisher He pointed to the great loss of ot life jfe caused by planes catching fire and declared fire still is the greatest flight risk The engine which In general de design design do- do sign resembles the gasoline engine in use In automobiles is is V V with Vo t converting banks of ot cylinders which ho he said will rte rte- 1000 horsepower r. r the average power now obtainable fronT from the fastest aircraft racing motors Tile The motor is water cooled but Dr Sperry said it Is not unlikely the principles of 01 air cooling can be adapted to his engine Dr Sperry is president of the tile Sperry Development company of ot Brooklyn and h has s been associated In his 1115 experiments with his sons Elmer A Jr and Edward and engIneers engineers engineers en en- g of the company
