Dear Internet Archive Community,
I’ll get right to it: please support the Internet Archive today. Right now, we have a 2-to-1 Matching Gift Campaign, so you can triple your impact, but time is running out! Most can’t afford to give, but we hope you can. The average donation is $45. If everyone reading this chips in just $5, we can keep this website going for free, and free of ads. That's right, all we need is the price of a paperback book to sustain a non-profit website the whole world depends on. For 23 years this has been my dream: for a generation of learners who turn to their screens for answers, I want to put the very best information at their fingertips. We stand with Wikipedians, librarians and creators to make sure there is enduring access to the world’s most trustworthy knowledge. We’re dedicated to reader privacy so we never track you. We don’t accept ads. But we still need to pay for servers and staff. The Internet Archive is a bargain, but we need your help. If you find our site useful, we ask you humbly, please chip in. Thank you.

Testing was conducted to determine the free air blast overpressure of the 2.75 inch rocket motors MARK 40 and MARK 66. Data were collected for single and ripple firings of both type of rockets. 'Pressure maps' were generated to display the results. Topics: DTIC Archive, Bergman, Robert, ARMY MISSILE COMMAND REDSTONE ARSENAL AL GROUND EQUIPMENT AND...
A number of binary mixtures, components of which are propellant ingredients, were examined in steel walled tubes for their DDT behavior at 60-70% theoretical maximum density (TMD). Several commercial propellants and one 4-component, composite model were also examined. A number of compositional effects were noted and reported. Some propellants, at high porosity, showed reaction not detectable by our ionization probes. For propellants which exhibited transition at 70% TMD in our apparatus, the...

A relativistic Brillouin flow equilibrium model is assumed for the plasma sheath and a cylindrical analytic solution including a uniform external magnetic field is obtained. A free parameter appearing in all previous magnetic insulation theories is shown to be accurately determined by maximizing the transmitted power flow. The theory is supported by particle-in-cell simulations. Topics: DTIC Archive, Mostrom, Michael A., LOS ALAMOS SCIENTIFIC LAB ALBUQUERQUE NM, *PLASMA SHEATHS,...
This program was sponsored in order that the performance of selected rain erosion coatings might be evaluated and that those parameters affecting the performance of these materials might be studied with the goal in mind to upgrade rain erosion coatings for use on high performance aircraft. In order to realize this goal, the following characteristics of two select polyurethane materials were evaluated: coating adhesion to the reinforced composite substrates; solvent evaporation rates or 'solvent...
