This book was released on 1965 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to solve many existing problems in planetary entry it is necessary to have facilities that are capable of launching undamaged projectiles at hypervelocities in excess of 50,000 ft/sec. Unfortunately, conventional lightgas guns appear to have reached a velocity plataeu of about 30,000 ft/sec or less for launching integral aerodynamic models. It is shown that by a novel application of combustion-wave and shock-wave dynamics in gases and explosives that it is theoretically possible to achieve projectile velocities in the desired hypervelocity range. Some details are presented of the analysis, facility, and the research results obtained to date on spherical combustion of stoichiometric mixtures of oxygen and hydrogen diluted with helium or hydrogen, the initiation of propellants and explosives by using deflagration and detonation waves, and some initial launchings.

Book Synopsis Implosion Driven Hypervelocity Launcher Performance Using Gaseous Detonation Waves by : University of Toronto. Institute for Aerospace Studies
Download or read book Implosion Driven Hypervelocity Launcher Performance Using Gaseous Detonation Waves written by University of Toronto. Institute for Aerospace Studies and published by Institute for Aerospace Studies, University of Toronto. This book was released on 1967 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation of the performance of an Implosion-Driven Hypervelocity Launcher was made in preparation for the investigation of launcher performance using explosive liners. Initial gaseous mixtures of stoichiometric hydrogen and oxygen diluted with hydrogen or helium in the initial pressure range from 100 psi to 500 psi were used. The detonation velocities and the subsequent trajectories of the reflected shock waves in the hemispherical combustion chamber were determined for the various initial mixtures. The measured detonation velocities in this high-pressure range agree very well with theory. Gun performance for the various reservoir conditions was investigated and the performance utilizing imploding shock waves is compared to the performance using deflagrating or constant volume combustion.

Book Synopsis Appraisal of UTIAS Implosion-driven Hypervelocity Launchers and Shock Tubes by : I. I. Glass
Download or read book Appraisal of UTIAS Implosion-driven Hypervelocity Launchers and Shock Tubes written by I. I. Glass and published by . This book was released on 1970 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: A critical appraisal is made of the design, research, development, and operation of the novel UTIAS implosion-driven hypervelocity launchers and shock tubes. Explosively-driven (PbN6-lead azide, PETN-pentaerythritetetranitrate) implosions in detonating stoichiometric hydrogen-oxygen mixtures have been successfully developed as drivers for hypervelocity launchers and shock tubes in a safe and reusable facility. Intense loadings at very high calculated pressures (almost megabar range), densities (g/cc) and temperatures (thousands deg K), at the implosion centre, cause severe problems with projectile integrity. Misalignment of the focal point can occur and add to the difficulty in using small calibre (6 to 8 mm dia.) projectiles. In addition, the extreme driving conditions cause barrel expansion, erosion, and possible gas leakage from the base to the head of the projectile which cut the predicted muzzle velocities to half or a third of the lossless calculated values. However, in the case of a shock-tube operation these difficulties are minimized or eliminated and the possibilities of approaching Jovian reentry velocities are encouraging. In a recent run using about 100g of explosive PETN and 400 psi 2H2 + O2 a shock Mach number approx. 60 was obtained in air at an initial pressure of 1 torr in 1.0 in. dia. shock tube channel. In addition, the use of focused, explosive-driven implosion waves may have many other physical and technological applications. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A spectroscopic study has been made of imploding shock waves in a hemispherical chamber filled with an H2-O2-He mixture at high initial pressures. In particular, temperature measurements at the origin of the chamber were made. Specific attention was paid to the use of the device as a driver for the Implosion-Driven Hypervelocity Launcher.

Book Synopsis The Gas Dynamics of Explosions by : John H. S. Lee
Download or read book The Gas Dynamics of Explosions written by John H. S. Lee and published by Cambridge University Press. This book was released on 2016-07-21 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explosions, and the non-steady shock propagation associated with them, continue to interest researchers working in different fields of physics and engineering (such as astrophysics and fusion). Based on the author's course in shock dynamics, this book describes the various analytical methods developed to determine non-steady shock propagation. These methods offer a simple alternative to the direct numerical integration of the Euler equations and offer a better insight into the physics of the problem. Professor Lee presents the subject systematically and in a style that is accessible to graduate students and researchers working in shock dynamics, combustion, high-speed aerodynamics, propulsion and related topics.
