SHELF LIFE TEST OF CHARGE JETTISON, LAU-6/A
Abstract
T HIS TEST WAS INITIATED TO OBTAIN DATA TO DETERMINE IF THE SHELF LIFE OF THE CHARGE JETTISON LAU-6/A could be extended. The shelf life is currently four years. The LAU-6/A is used on the rocket launch rail of the F-89J aircraft. The serviceability of the jettison charge was determined by function testing 20 charges which had been in storage from 38 to 55 months. The resistance of the squib circuit and the strength of blast pressure generated, were measured when the charges were functioned. The blast pressure was easured by using 20 psi Wiancko pressure transducers. The average resistance of the squi circuits was 8.42 ohms, with a variation of 6.8 ohms. The average press re one foot from the end of the charge was 9.91 psi, and the average pressure one foot elow the charge was 15.09 psi. All jettison charges functioned normally. The pressure from the charges was approximately five times the theoretical amount required to shatter the bolt. It is recommended that the shelf life of the charge jettison LAU6/A be extended to five years. (Author)
