Country of Origin: United States GRA (NTIS NTS) Country of Publication: United States Abstract: The purpose of this test program was to study the resistance of units of varying material, shape, and strength in relation to atomic blast forces of varying magnitude. This test was conducted on a model basis, with the intent to coordinate results with theoretical analyses and dynamic resistance studies to form a reasonable basis for the design of blast-resistant structures.

Blast effects on aircraft in flight Corporate Source: Air Force Wright Air Development Center, Wright-Patterson AFB, OH (USA) Publication Date: 1 Sep 1985 Pp 287 Report Number(s): AD-A-995424/9/XAB Document Type: Report Language: English Journal Announcement: EDB8611 Availability: NTIS, PC A13/MF AOl1. Subfile: ERA (Energy Research Abstracts). GRA (NTIS NTS) Country of Origin: United States Country of Publication: United States Abstract: The primary objective of this report is to present data concerning the structural and aerodynamic loads as measured on various types of aircraft in flight in the vicinity of an atomic explosion. A secondary objective is to describe the instrumentation (installation, calibration, and operation) in order to provide for the future planning and conduct of similar tests. The positions of the airplanes at the time of shock arrival were accurately determined by means of radar tracking. The measured data were correlated, every second, from a land-based radio-transmitter station and with reference to time zero by means of a photoelectric cell. The data obtained are believed to be accurate to within 10% and is suitable or further analysis and Satisfactory for the development or correction of a technique for calculating the effects of atomic explosions on aircraft structures.
