Vectored Thrust Digital Flight Control for Crew Escape. Volume 1.
Abstract
Work of Meyer and Cicolani was adapted for application to open seat escape systems in current Air Force fighter aircraft. The control system design is a fully self-contained system whose major on-seat components are: acceleration, rate, attitude and altitude sensors, real-time control logic imbedded on a microprocessor chip, rocket thrusters with thrust vectoring and throttling capability, and various avionics and support subsystem hardware items (e.g., power supply). The control concept is based on a comparison of measured translational and rotational accelerations with desired values; the propulsion system is then configured to provide adequate energy to follow the desired trajectory and simultaneously eliminate acceleration errors. The concept uses nonlinear models and incorporates state and control constraints. This volume contains the detailed documentation of specification development, control logic design, hardware identification, and trade study efforts. Volume II (Ad-A166 596) contains a description of the prototype design, real time breadboard simulation, and the results and analysis of the verification task. Volume III contains the supporting appendices for volumes I and II. Volume IV details the results of the real time hybrid computer simulation effort. Keywords: Modern control theory, Model algorithmic control, Acceleration control, Ejection seat control.
