The general airplane equations of motion are developed and used to calculate transfer functions for a Cessna 172 airplane. Automatic controllers were designed for four common autopilot modes (pitch control, altitude hold, roll control, and heading hold). Implementation of a flight control design was accomplished using single degree of freedom roll equations for a model airplane wing. The feedback compensation design was ground tested in a simulated wind tunnel and met performance requirements. All the elements of automatic flight control design are described in this report.iii, 77 leavesBTDapplication/pdfenIn CopyrightLD5655.V851 1990.W643Aerodynamics -- Mathematical modelsAirplanes -- Mathematical modelsAutomatic pilot (Airplanes) -- DesignMaster's projecthttp://scholar.lib.vt.edu/theses/available/etd-01202010-020132/
