Carrier flow removal signalling sensor for slow flying aircraft e.g. hang-glider

摘要: The appts. includes a low-mass, one armed lever (1) of elastic material. material is stretched tight and it carries contact vane (2). free end the has an overhanging surface (3) upon which air flow incident. A disturbance incident on bends actuates contact. preferably made electrically conductive material, e.g. stainless steel. cross-section rectangular with ratio width to thickness greater than thirty. in range 0.01 mm 0.1 but between 0.02 0.03 mm. window (4) may be provided near foot lever, through sprung part (5) fixed, stabilise direction movement lever.
