28 May 1971TL;DR: In this article, the authors proposed a solid propellant rocket motor with a controlled rate of thrust buildup to a desired thrust level by the combined utilization of a regressive-burning controlled flow solid- propellant igniter and a progressive-burning main solid-propellant charge, where the igniter is capable of operating in a vacuum and sustaining the burning of the propellant below its normal L* combustion limit until the burning propellant surface and motor chamber pressure has increased sufficiently to provide a stable motor chamber.

TL;DR: In this article, a new electrostatic probe technique for determining the depletion of electrons in a plasma due to the introduction of an electron-attaching gas is presented. But the technique is implemented in such a way that all complicated chemical kinetics associated with the electron attaching gas and plasma are avoided.
Abstract: A theory is derived for a new electrostatic probe technique for determining the depletion of electrons in a plasma due to the introduction of an electron-attaching gas. The technique makes use of the positive ion saturation currents and the difference of floating potential. No negative species saturation current measurement is made. The technique is implemented in such a way that all complicated chemical kinetics associated with the electron-attaching gas and plasma are avoided. The utility of the technique was demonstrated in an arcjet experiment in which a readily measurable change in probe floating potential was observed, an indication that the local electron density had been significantly reduced by electron attachment to form negative ions. The arcjet was found to provide a satisfactory flow field for investigation of the effectiveness of various electrophilic gases.
