Download or read book Investigation of the Effect of Low Thrust Levels on the Base Pressure of a Cylindrical Body at Supersonic Speeds written by T. A. Martin and published by . This book was released on 1970 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of supersonic wind tunnel tests are presented which show the effects of varying nozzle geometry, location, and supply pressure on the base pressure of a cylindrical body at zero angle of attack. The purpose of the tests was to investigate the parametric influences in the regions where base pressure is near a minimum, which occurs in the lower range of thrust levels. A bibliography of related experimental results is also included.
Book Synopsis An Experimental Investigation of Base Pressure on a Body of Revolution at High Thrust Levels and Free Stream Mach Numbers of 1.5 to 2.87 by : Joseph C. Craft
Download or read book An Experimental Investigation of Base Pressure on a Body of Revolution at High Thrust Levels and Free Stream Mach Numbers of 1.5 to 2.87 written by Joseph C. Craft and published by . This book was released on 1970 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation of axial jet effects on the base and afterbody pressures on a body of revolution has been made at free stream Mach numbers of 1.5, 1.75, 2.00, 2.50 and 2.87. Variations were made in nozzle and afterbody geometry while chamber pressures were varied from zero to 1000 psia. For the larger nozzles, sufficient jet mass flow was emitted to cause boundary layer separation on the body surface.
Book Synopsis A Summary of Jet Plume Effects on the Stability Characteristics of a Body of Revolution with Various Fin Configurations at Mach Numbers from 0.2 to 2.3 by : George Batiuk
Download or read book A Summary of Jet Plume Effects on the Stability Characteristics of a Body of Revolution with Various Fin Configurations at Mach Numbers from 0.2 to 2.3 written by George Batiuk and published by . This book was released on 1976 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the studies made to date by the Army Missile Command on the effects of the rocket jet plume on the Stability characteristics of a body of revolution with various fin configurations and at various fin positions on the body. The Mach numbers ranged from 0.2 to 2.3. A normal jet plume simulator was used to obtain the desired plume effects. This report concerns itself with those tests conducted on a 5-in. diameter, 52-in. long model, with a 3 caliber tangent ogive nose.
Book Synopsis The 2002 Version of the Aeroprediction Code by : Frankie Gale Moore
Download or read book The 2002 Version of the Aeroprediction Code written by Frankie Gale Moore and published by . This book was released on 2002 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new version of the aeroprediction code (APC), the AP02, has been developed to address the requirements arising from advanced weapon concepts. The AP02 was formed by adding significant new technology and several productivity improvements to the previous version of the APC, the AP98. New technology added included 6 and 8 fin aerodynamics, improved nonlinear aerodynamics, improved pitch damping predictions, improved power-on base drag estimates, base-bleed effect on base drag estimation, improved axial force of nonaxisymmetric bodies and trailing-edge flap capability. Other improvements and productivity enhancements include an aerodynamic smoother, ballistic and three degree-of-freedom simulation modules as well as refinements for the pre- and post-processor for inputs and outputs of the AP02. Comparison of the predicted aerodynamics of the AP02 to AP98 and experimental data showed the AP02 to be slightly better than the AP98 in most cases that both codes would handle. However, due to the additional new technology incorporated into the AP02, many new options are available in the AP02 that are not available in the AP98. Therefore, the AP02 is more robust and, on average, is slightly more accurate than the AP98 in predicting aerodynamics of weapons.

Book Synopsis Investigation of the Wake Behind a Body Flying at Supersonic Speed by : Yu O. Panov
Download or read book Investigation of the Wake Behind a Body Flying at Supersonic Speed written by Yu O. Panov and published by . This book was released on 1968 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: A state-of-the-art report and critique of base flow and base pressure research in the wake at supersonic speeds is given. Classical and modern experiments (Crocco-Lees, Chapman, Bogdanov, Charwat, et al) are tabulated, and hypotheses are analyzed. The discrepancies, inconsistencies and contradictions contained in various theories are pointed out. The problem of base pressure is closely related to the dynamics of the flow boundary of the wake behind the body, and to the effects of the boundary layer which is separated from the trailing edge upon the mixing process. The overall state-of-the-art indicates that the laws of base flow are not sufficiently researched, and not enough experimental data is available to verify, or disprove, some of the available hypotheses. The following are some of the areas that require additional investigation: (1) Distribution of the velocities, pressures and temperature in the reflux; (2) Structure of the flow boundary in the wake for a plane and three-dimensional case, for both laminar and turbulent mixing; (3) The effect of the geometric characteristics of the body upon the base flow; (4) Mass and heat exchange phenomena; (5) Heat exchange at the base at various conditions of circumfluence; (6) Turbulent mixing coefficient in supersonic flows in general, and in non-isothermic and isobaric flows in particular.
