An instrument is suggested fro the measurement of supersonic flow inclination, taking advantage of the effect of angle of attack on the meridional velocity profile of the laminar boundary layer on a cone. This effect of angle of attack may be measured by the difference of total pressure recorded by two probes pointing toward the apex and located in the plane of symmetry of the flow.
