Abstract
  • A problem found in high speed transport aircraft is excessive tail loading when flying at cruise speeds through turbulence. Attempts to reduce these areodynamic forces on the tail may result in unstable aircraft motions. Using a linear quadratic regulator in conjunction with a Kalman filter, the feasibility of designing an autopilot utilizing the ailerons and rudder is studied in terms of minimal combined lateral ride motion and aerodynamic tail force. A new numerical algorithm for solving general quadratic regulator and state estimation problems is developed, and is presented with a computer program to solve the complicated matrix equations involved. A systematic procedure is also developed for choosing a reduced combination of sensors which gives near optimal performance. With this approach, aerodynamic tail forces can be theoretically reduced by 20 to 50 percent.
