The effect of cowling on cylinder temperatures and performance of a Wright J-5 engine

The effect of cowling on cylinder temperatures and performance of a Wright J-5 engine

Date: January 1, 1930
Creator: Schey, Oscar W & Biermann, Arnold E
Description: This report presents the results of tests conducted to determine the effect of different amounts and kinds of cowling on the performance and cylinder temperatures of a standard Wright J-5 engine. These tests were conducted in conjunction with drag and propeller tests in which the same cowlings were used. Four different cowlings were investigated varying from the one extreme of no cowling on the engine to the other extreme of the engine completely cowled and the cooling air flowing inside the cowling through an opening in the nose and out through an annular opening at the rear of the engine. Each cowling was tested at air speeds of approximately 60, 80, and 100 miles per hour.
