Abstract:

This paper describes a new technique for the reduction of electron density in the reentry plasma sheath. A brief history of the problem and a description of various alleviation schemes are presented. A description of the room temperature experiment which first demonstrated enhanced attachment is given, followed by a description of the plasma arc-jet experiment used to demonstrate the effect at high gas temperature. It is seen that oxygen is added via a nozzle to a nitrogen arc jet. The resulting flow passes through an rf coil and an S-band microwave diagnostic test section. The rf coil is used to heat the electron gas. Curves are presented which show the measured reduction in electron density both when oxygen is present in the flow and when rf heating is applied.
