OH-58F Flight Control Authority and Architecture Investigation

A detailed design analysis will be performed of the Stability and Control Augmentation Systems (SCAS) architecture for the Kiowa OH-58F Block II upgrade. The Kiowa Warrior presently has a 10% partial authority SCAS currently flown in the OH-58D/F rotorcraft. Our approach to enhancing the SCAS capability is to take flight dynamic models developed from recent Army research and develop simulations and run them with a variety of actuator configurations and sensor quality under varying flight conditions. Attitude Command, Attitude Hold, and Height Hold (ACAH-HH) Flight control laws for the various architectures will be designed and tuned to achieve Level 1 Handling Qualities.
