Abstract

This report covers tests made on the Mk 25 torpedo to determine the effect of gas discharged through a horizontal expanding exhaust pipe, being the second supplement to the report, Section No. 6.1-sr207-1275. This testing was requested by Dr. E. H. Colpitts , Chief of Section 6.1 , NDRC , in a letter dated May 4, 1944. As in the two former series of tests, the object was to determine the feasibility of discharging the turbine exhaust gases through the fin structure instead of through the propeller shafts. Several different lengths of exhaust pipe were tested; also runs were made for various values of velocity, submergence, and quantity of gas discharged. Photographs were taken to show the exhaust cavities under the different conditions.
