Available in PDF, EPUB and Kindle. Book excerpt: Introduction: In connection with a study of the bomb flight path, the Materiel Command of the Army Air Forces requested the NACA to conduct aerodynamic tests of a 300-pound M-31 demolition bomb. Force tests at angels of attach from -15° to 30° were made up to a Mach number of 0.725, which corresponds to a speed of 810 feet per second at sea level. These tests were made in the NACA 8-foot high-speed wind tunnel at Langley Memorial Aeronautical Laboratory.

Book excerpt: The results of an investigation in the NOL 40 X 49 cm aeroballistics tunnel no. 1 to study the static stability and drag of the low-drag bomb at subsonic and supersonic speeds. The following tests were made: (a) study of configurational changes designed to reduce the yaw of the bomb; (b)drag of the 250-pound bomb with supporting lugs; and (c) stability of an 8-fin bomb with reduced fin span to improve the ground clearance problem.

Schermerhorn and published by . This book was released on 1969 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: The static-stability index, force and moment coefficients are presented as functions of angle of attack for the Mk 82 Low-Drag Bomb with Standard and Emtex Snakeye I Fins. For these tests the fin-opening angles were 60, 70, 80, 90, 100 and 110 degrees; the models' angle of attack ranged from -10 to +20 degrees; the free-stream Mach number was varied from 0.25 to 0.95, and roll angles were at 0, 22.5 and 45 degrees.

Available in PDF, EPUB and Kindle. Book excerpt: The drag database of the Mk 82 general purpose low drag bomb, the primary gravity weapon in the RAAF inventory, has some shortcomings in the quality and traceability of data, and in the variations due to configurational differences. Extensive testing of scaled models in a wind tunnel and an aeroballistic range facility have resulted in establishihg estimates of the drag of a clean Mk 82 bomb as well as the incremental drag of add ons such as lugs and fuzes. These results, together with data obtained from full scale bomb drop trials, have been used to produce drag estimates for a full range of bomb configurations and release conditions. It is recommended that these data be incorporated into the mission computer of the weapon delivery system of the updated F111C aircraft. Furthermore it is recommended that the accuracy of these data be validated when the updated aircraft undergoes ballistic accuracy verification flight trials.

Available in PDF, EPUB and Kindle. Book excerpt: Since 1964 extensive and successful collaboration in a bomb dynamics program has continued between research organizations in Australia, the United Kingdom and the United States. Various aspects of this joint effort have been reported in separate reports: Part 1 treated the dynamics, aerodynamics and performance of free-fall weapons stabilized by fixed cruciform stabilizers. Part 2 gave a similar treatment of split-skirt stabilizers. Part 3 reviewed results obtained from the use of freely spinning panel stabilizers. This series of reports is concluded in the present document which discusses the task of the ballistician in light of the knowledge gained during the program and illustrates the application of the techniques derived to missile design. In addition, brief reference is made to a number of research projects which have stemmed from the original tripartite work.

Available in PDF, EPUB and Kindle. Book excerpt: Transonic wind tunnel tests have been conducted on a 1/8th scale model of a Mk82 bomb. The tests covered an incidence range of -2 deg to 28 deg and a Mach number range of 0.95 to 1.20 for roll angles between -45 deg and + 45 deg. The tests indicated that the model exhibited static longitudinal stability for all conditions except at low Mach numbers and incidences greater than about 20 deg. (Author).

Download or read book Aerodynamic Tests of an AN M 65 AZON 1000 pound Radio controlled Bomb in the LMAL 16 foot High speed Tunnel written by E. O. Pearson and published by . This book was released on 1944 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: Tests were made in the LMAL 16-foot high-speed tunnel to determine the aerodynamic characteristics of a 1000-pound AN-M-65-AZON radio-controlled bomb at Mach numbers ranging from 0.2 to 0.6. Over the Mach number range covered in the tests the hinge-moment coefficients, yawing-moment coefficients, and lateral-force coefficients exhibited no important changes with increasing speed. The drag coefficients increased gradually with increasing Mach number but no sudden increases were observed. The effect on the bomb aerodynamic characteristics of antenna struts mounted on the bomb tail was found to be small. The rudder and aileron operating mechanisms were found to be capable of supplying several times the required torques for maximum control deflections at a Mach number of 0.6 at sea level. The operating mechanism is also adequate for maximum control deflections at a Mach number of 1.0 provided that no appreciable increases in hinge-moment coefficient occur between M = 0.6 and M = 1.0. However, because of uncertainty as to the value of the hinge-moment coefficient at or near M = 1.0, the desirability of providing more powerful control mechanisms was indicated.
