Problems previously reported in the Moisture Resistance, Thermal Shock and High Impact Shock tests have been resolved. Performance on Group V tests has verified that a taut band suspension has been evolved which will withstand the shock test with no immediately apparent detrimental effects. Band breakage during vibration has been greatly reduced as the result of the conclusions of a large scale study of band breakage reported last quarter. Isolated failures due to band breakage during vibration have occurred however. All design work is essentially complete. Tooling has been completed for nearly all parts. Testing was concluded in the selection of the steel alloy for the iron vanes. Work on refining equipment and production problems was performed on a number of parts after initial samples from the tooling were received. Author
