- Summary:
- Studies were made in the air movements in the N.A.C.A. glass-cylinder apparatus using cylinder heads similar to those on the Wright R-1820-G engine and the Pratt and Whitney Wasp engine as modified by the Eclipse Aviation Corporation to use fuel-injection equipment. The air movements were made visible by mixing small feathers with the air; high-speed motion pictures were then taken of the feathers as they swirled about in the glass cylinder. The test engine speeds were 350, 500, and 1,000 rpm. Motion pictures were also taken of gasoline sprays injected into the cylinder during the intake stroke.
- The air flow produced by each cylinder head is described and some results of the velocity measurements of feathers are presented. The apparent time intervals required for vaporization of the gasoline sprays are also given.
