Abstract : Information about the plasma density profile in an aerodynamic flow field of plasma adjacent a supersonic space vehicle or test model is provided by a flush mountable plasma density profile probe device having at least three striplines embedded in and separated by a dielectric support member from a conducting ground plane there below. In operation, the device is affixed flush and conformally to the surface of the space vehicle or test model. The plasma density profile is determined from a plot of data points derived from sequential measurements, in the plasma flow field environment, of the conduction between a driven stripline and parallel flush embedded additional striplines in the order of the nearest stripline to the furtherest stripline from the driven stripline. Standard formulas can be applied to determine the data points.
