ee 0018933 LATER RESEARCH It is seen in Figures A-1 and A-2, illustrating the programming of the rocket and the nose section of the nose section of the rocket, that the system is a complex one. In the early stages of work on the rocket, prior to the field operation, it had been recognized that the chance. of having a completely operational system ready for sampling the HARDTACK clouds was small, due to the short length of time available for development and test firing. Neverthe- less, it seemed possible that defects of a minor nature which remained could be rectified in the field. The operational flights and tests already described show that significant progress was made toward this objective. However, after the tests of 24 June, it became apparent that the cause of nose cone leakage and other malfunctions could not be determined and corrected with facilities available at the Pacific site. Further work, utilizing range and test installations in the United States, was essential to the attain- ment of a completely successful sampling system. Accordingly, the rocket portion of Project 2.8 was terminated on 27 June with the concurrence of the Chief, AFSWP, and the Division of Military Applications, AEC. all unfired rounds were. shipped to California. From July to December 1958, the Cooper Development Corp. tested the rockets from the EPG to investigate possible modes of entry of water into the sampling heads (Reference 57). rart ( aan p> J oul Three nose cones identical to those flown in the last Pacific rounds a ..
