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.

This book was released on 1997 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method is described to determine the drag characteristics of the Mk 82 low drag bomb. This involves launching half scale models from the DSTO gas gun facilities at Port Wakefield and measuring the trajectories by photogrammetric methods. The drag coefficients were calculated from the measured positional data using a three degrees of freedom parameter estimation method. The estimated drag characteristics of various Mk 82 GPLD store configurations will form the basis of a database for use with the updated F-111C aircraft.

This book was released on 1972 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flutter analysis of the F-4C/D/E wing were conducted for two types of low-drag general purpose bombs mounted on the outboard wing pylons to investigate possible carriage to 650 knots equivalent airspeed or M - 1.4, whichever is less. The bombs analyzed were the MK84 suspended directly from the pylon and the MK82 installed on the multiple ejector rack (MER). Analytical wing flutter stability trends were investigated for a number of parameters for carriage of the two bomb types. The investigation included evaluation of effects on wing flutter of aircraft internal fuel, tolerance variations in bomb inertia characteristics, flight altitude, and Mach number for symmetric and antisymmetric modes. Studies were made of MK82 bomb loading configurations resulting from the normal bomb release sequence from a fully loaded MER and from hung bombs, which occasionally occur on the MER shoulder positions. Basic data which were utilized in these analyses are included in this report. Results of the flutter analyses indicate that the MK84 bomb, the fully loaded MER with six MK82 bombs, and all but three of the MK82 bomb partially loaded configurations can be cleared for carriage to 650 knots equivalent airspeed or M = 1.4, whichever is less. For these three MK82 bomb loading configurations, flight testing is recommended to establish if adequate damping and/or velocity margins exist for the potentially critical modes throughout the flight envelope goal.

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: Aerodynamic analyses and wind tunnel test data were used to investigate a new dispersion technique for general purpose and cluster bombs released on skids from cargo aircraft. Using the present approach, all bombs tend to impact in the same small area. The new technique involved the addition of a drag plate to the rear of the bomb fin assembly. The use of two sizes of plates (plus the standard configuration) would provide three ballistic trajectories for the bombs mounted on one skid. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This report contains results of tests conducted to evaluate a ballute retardation system(combination balloon/parachute) for a Mk 82 bomb. The system tested provided for a low drag configuration of either of two types of high drag options. One high drag option (29-inch diameter ballute) was designed for mine application and the other (41-inch diameter ballute) for general purpose bomb application. Tests demonstrated the system was physically compatible with the F- 100 and F-4 aircraft. Flight tests demonstrated the system could be safely carried and released from the F-100 aircraft in level flight up to 550 KTAS. Ballistic data were obtained on all configurations used during the flight test. The average time for the 29-inch and 41-inch diameter ballute to fully inflate after release was 0.8 second and 0.7 second, respectively. The G-loads experienced during deployment of the 41-inch diameter ballute were sufficient to arm three of four FMU-54/B fuzes tested. The fourth fuze did not arm. Burial characteristics for the 29-inch diameter ballute varied from 2 to 8 feet horizontal travel from impact point, 5 to 12 feet deep, and at an attitude of 45 to 90 degrees nose-down. The ballute system successfully functioned 12 of 15 times tested. One of the 41-inch diameter ballute fabrics tore loose from the canister during deployment and two 29-inch diameter ballutes fluttered from release to impact.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents results of a study conducted to determine the arming time that should be recommended for each combination of aircraft type, release condition, bomb type, and post-release maneuver, as well as a discussion of the methods used to arrive at the recommended arming times. The aircraft types considered were A-4, A-6, A-7, and F-4. The release conditions considered were level attitude with no post-release maneuver, and dives followed by application of a 4G recovery force within two seconds after release of the last bomb. The tabulations presented do not replace the tactical manual recommendations, but rather present supplementary information for those interested. (Author).

This book was released on 1970 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effectiveness of a weapon system using the Mk 82 bomb requires that the bomb follow a specific trajectory during earth penetration to a terminal location of desired depth. This report presents the results of a preliminary investigation of the effect of nose shape, impact velocity, and impact angle on the trajectory of 1/25-scale models of the Mk 82 low-drag bomb in a silty sand soil. It was found that a spherical nose configuration achieves a relatively consistent and reproducible trajectory of the desired shape, and its response is less sensitive to impact angle and flight attitude than either the ogival or conical nose configurations. Scaling equations, such as those of Poncelet, Petry, Laumbach and Young, were used to predict the response of the prototype from the model tests. A theoretical expression for vertical penetration developed by John Harri was found to be applicable in the prediction of the response of the prototype. Additional tests were conducted to determine the effect of the medium on the trajectory of the projectile. From tests into clay, sand, and stratified layers of clay and sand, it was found that the effectiveness of modeling depends on the knowledge of the properties of the penetrated medium. (Author).

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.
