The steam accumulators which are to be installed at the TC13 catapult site, Naval Air Test Facility (Ship Installations) Lakehurst, New Jersey have been designed and analyzed in accordance with standard codes to insure safe operation for a specified type and number of catapult service cycles. The number of types of service cycles is infinite according to aircraft weights and end speeds, stand-by pressures, and charge-up and blow-down rates. For this report two representative cycles were selected for analysis: a typical high pressure catapult shot and a wide range charge-up blow-down operation. (Author).

This study was made to determine if the fatigue life of a steam accumulator can be extended by any of a number of methods. Six separate studies investigate analytically or logically the possible methods. As discussed where appropriate, some methods can be completely evaluated only by both studies and test data. The problem in accumulator design is that the observed fatigue life as manifested by cracking has been found to be less than the calculated fatigue life. Inspection of accumulators in fleet service has revealed extensive cracking near the manhole and near the nozzles. The accumulators which are installed at N.A.T.F., Lakehurst, New Jersey have had severe cracking at the head shell junction and at some nozzles. Almost all cracking has occurred on the inside surfaces. (Author).

This stress nalysis was prepared for the purpose of determining the safe fatigue life of the existing TC13 steam accumulators and of establishing a set of test-site operating procedures. Cracks were found at various locations on the inner surfaces of the steam accumulators which have been in use since 1958 at the U.S. Naval Air Test Facility (Ship Installations) (NATF(SI)). These cracks, if not repaired, may propagate and cause the vessel to rupture. The cracking phenomenon is, therefore, extremely hazardous. (Author).

The various methods used to inspect the steam accumulators were visual, magnetic particle and dye penetrant, radiographic, and ultrasonic. All cracks 1/4 in. or less in depth were ground out and faired; cracks greater than 1/4 in. in depth were repaired by grinding, welding, and stress relieving. Almost all defects foundd during the inspections of the steam accumulators were in the circumferential welds and large nozzle forgings to shell welds, which are areas of high stress concentration and appear to be most affected by rapid and large changes in steam conditions. Grinding, welding, and stress relieving of cracks in the steam accumulators proved to be an acceptable repair practice, and aided in prolonging accumulator service life.

Bibliography on the Fatigue of Materials, Components and Structures, Volume 3 addresses the problems associated with fatigue loadings as evident in branches of engineering and technology. Such debilitating factor also affects the human skeletal system. The book provides several references that show an increasing focus being given to the problem of fatigue in materials, components, and structures. The journals and lists of references used in the book, which discuss the subject of fatigue, are chosen to give an initial identification of citations. These sources are accompanied by computer-based documentation systems. The bibliographical data for each citation are thoroughly reviewed by checking the original bases of publication. The references in the book are arranged chronologically according to its year of publication. Major use has been made of abbreviations for the titles of journals and publications. The book can serve as a valuable tool for doctors, therapists, students, and researchers in the field of medicine.
