Abstract
An improved engine for aeronautical applications includes a forged cylinder block having a drive device rotatably mounted therewithin and a motive device for rotating the drive device, the motive device including two cylinder banks in a V-type configuration and a plurality of cylinders mounted within the cylinder banks for producing power and rotating the drive device. The forged cylinder block further includes a plurality of cylinder cavities formed in the cylinder banks and the upper approximately one-third of each of the cylinder cavities is generally surrounded by a generally toroidal cooling chamber, and the lower approximately two-thirds of each of the cylinder cavities is generally free of any surrounding cooling chambers. Finally, a coolant circulation device in fluid transmission connection with each of the cooling chambers is operative to circulate cooling fluid therethrough whereby the upper approximately one-third of each of the cylinder cavities is cooled by the cooling fluid.
