...flying time and they took precautions because, underneath the chain-wrapped tarpaulin, was the first diesel-type motor ever used successfully for airplane propulsion. The flyers were Mechanical-engineers Lionel M. Woolson and Walter Edwin Lees. Their employer, developer of something new and great in the air, was Packard Motor...
Five years Engineer Woolson and his research staff at the Packard plant have labored designing the motor. They had, first, the diesel principle to go on, i.e., that air can be heated by compression until hot enough to ignite a jet of fuel...
Their accomplishment, reached and tested episodically last year, is a nine-cylinder, radial, air-cooled motor. It lacks, of course, the sparkplugs, wires, magnetos, etc., essential in spark-ignited gasoline engines. A pipe line distributes oil under pressure to each of the cylinders. The present machine delivers 200 h.p., and is slightly less in diameter than gasoline radials of like power. It weighs nearly 3 Ib. per h.p., against the average 2 Ib. per h. p. of gasoline types. But it travels farther and more cheaply on a gallon of its fuel. For example, last week's 7-hour...
They lately met again in Kansas City after years during which Ace Wolff was an engineer for the Mercedes and Junker concerns. Play-managing did not appeal to Ace Wolff so strongly as the chance to return to the air which was offered him in Sioux City by Arthur S. Hanford Jr. of Hanford Tri-State Air Lines...
