Electro-optical System Measures Aircraft Deflections
Abstract
In-flight deflections of aircraft surfaces are measured accurately over wide range of airspeeds and attitudes by electro-optical instrumentation system. Deflections caused by aerodynamic and acceleration forces are measured on wings, stabilizers, helicopter rotors, and other surfaces. Electro-optical system replaces 70-millimeter motor-driven camera previously used to observe deflections.
