Product Improvement Test of T53-L-11 Engine
Abstract
Product improvement of the UH-1( ) helicopter has been and is a continuous process. To reduce cost and weight and to increase service life, certain components of the T53-L-11 gas turbine engine have been modified. Several product-improvement items were tested in engine, S/N LE-06005X, during the Product Improvement Test of T53-L-11 Engine in the UH-1D Helicopter, USATECOM Project No. 4-5-0151-01 (reference j). That engine was removed after 941 test hours because of failure of the number four bearing, which was not a test item. To provide more statistical samples and to obtain results from 1200 test hours, items comparable to those previously tested and certain other items were installed on T53-L-11 engine, S/N LE-09753, and entered into the product- improvement test program.
