Mullaney 4h a\ The hyiredynamio yield of ve =» determined on the basis of dianeter-tine data froe three aan films as The data consisted of ow Sila “som onsh of three stations; Parry (35429), Mack (35423), ani Piireai (35435). Valves of yield obdtaine! from iniividusl frames of a given fila are in good agree ment vith one ancther; the aaximm wariation for Mack was 41.5% and 1,08, for Piireat 2.5% and =0.5$, and for Parry £0.5f and -9.0%. The mximm variation in yieli between the three films was about /5f to -7%. Results of computatinn using the integrel, 4ifferential, ani Mach number goaling sethois, as descrihei in previous reports, are presented fa Table 10.1-1. computations. The Bethe-Puchs Mass Treatment has been use! in al) These methois have reduced the soatter of re-ulting ylelis to about £ 2% among the three films. Because of mfficient uncertainty in the amount of mass vaprrised by the Mreball an‘ sepable of influ encing the hyirotynamic grovth of the shock front, the effects of three possible mass distributions is cresented. The inclusion of £6,400 Pounds weight. correepanis to the cab material with massive structural . beams omitted; the 68,500 pound tistritution incluies in addition about one-half of the heavy beans, while the 91,4 poun! distribution ‘oonsidera the entire cab plus about ten feet of the adjacent tower. Purther work of a more fundamental nature is pleaned OS obtain more as@ curate estimates of the mss effect. COPY BEST AVAILABLE corey
