An inductive probing scheme, originally developed for shock tube studies, has been adapted to measure explosive plasma jet conductivities. In this method, the perturbation of an applied magnetic field by a plasma jet induces av oltage in a search coi

Basic material properties determine the amount of solar energy that is absorbed, transmitted or reflected and these values will often change with differing temperatures. This investigation developed a new approach to evaluate the material properties

One possible approach to pitch control of an air-breathing reusable launch vehicle is differential throttling of opposite engines mounted on the conical lifting body. The vehicle must operate over a large range of ight regimes. The problem is aggr

Storable liquid propellants are stored for extended periods of time in metal tankage prior to usage in rocket engines. Knowing the chemical interaction of the propellant and the tankage material is essential to evaluating the structural integrity of
