Relaxed Static Stability Aircraft Design via Longitudinal Control-Configured Multi-disciplinary Design Optimization Methodology

This paper describes a multi-disciplinary design optimization approach to the conceptual design of a commercial aircraft with relaxed static stability. Longitudinal flight dynamics analysis and control design are performed concurrently with other disciplinary analysis to augment and improve handling qualities. The developed methodology enables control-configured designs providing higher freedom of change at the conceptual design stage. A design example demonstrates the effectiveness of the proposed integrated approach to improve performance goals.
