Skin Friction Measuring Device for Aircraft

摘要

A skin friction measuring device for measuring the resistance of an aerodynamic surface to an airstream is disclosed. It is characterized by a friction plate adapted to be disposed in a flush relationship with the external surface of the aircraft and be displaced in response to skin friction drag as an airstream is caused to flow over the surface. A potentiometer is connected to the plate in order to provide an electrical output indicative of the magnitude of the drag.
