Abstract : The fluid stall sensor is a remote indicating system for detecting stall on aircraft wings. When the flow is attached to the wing, it causes aspiration from a probe just above the wing surface. Separated flow, associated with stall, decreases the aspiration. The change in aspiration is amplified by a high impedance fluid amplifier which drives an indicator. The position of indicators from several probes across the wing gives an indication of the amount of lift remaining. (Author)
