Краткое описание

It is known that the microwave technique provides the highest spatial resolution when determining displacement of the burning (regressing) surface. This gives promise for developing an effective direct method for measuring the transient regression rate of solids. However, there are serious limitations to the method due to attenuation and secondary reflections of the microwave energy. Unfortunately, despite several decades of development, information is very scarce in the open literature on the technical possibilities and correct use of the microwave method. In the present paper, the potential sources of errors due to non-planar (rough) burning surface, scatter of electromagnetic wave on metallic particles, attenuation of radiation in finite-length propellant samples, and reflection of radiation from the waveguide elements and high-pressure vessel walls are analyzed. Some methods for diminishing and eliminating the disturbing factors are suggested. Recommendations for optimization of parameters of the propellant samples and microwave measurement system are discussed.
