- Summary:
- An investigation was made to obtain information on the minimum quantity of air and power required to cool conventional air-cooled cylinders at various operating conditions using a blower. A Pratt and Whitney Wasp H and a Pratt and Whitney Wasp D cylinder were used with two different cooling-air jackets on each cylinder. The cooling air was supplied by a blower and measured with a Durley orifice box. Cylinder temperatures were measured with iron-constanan thermocouples connected to a portable pyrometer. Tests were made at engine speeds varying from 1,500 to 2,100 r.p.m. with atmospheric pressure at the carburetor and at an engine speed of 1,900 r.p.m. with carburetor-intake pressures varying from 20 to 35 inches of mercury absolute. The weight of the cooling air was varied from approximately 0.56 to 1.82 pounds per second.
