The development of a floating element skin-friction gage is described which can be used in high temperature hypersonic flow of gases. The surface in contact with the flow is actively cooled to withstand a wide range of heat transfer rates. The effect of input voltage on coil temperature and output voltage are given. A mechanical hysteresis was found. The friction gage was installed in a channel in which a two-dimensional viscous flow was established. The friction force and flow conditions were measured.
