Abstract
High-altitude, long-endurance (HALE) aircraft are highly flexible, requiring nonlinear aeroelastic analysis. NATASHA (Nonlinear Aeroelastic Trim and Stability of HALE Aircraft) is a computer program developed to analyze the aeroelastic behavior of HALE aircraft. The underlying formulation is based on the published geometrically exact, fully intrinsic beam equations. This paper presents a wide range of results from NATASHA, comparing them with well-known solutions of beam stability and vibration problems, experimental data, or results from well-established computer codes. Despite the simplicity of the underlying formulation, results obtained confirm the accuracy of the analysis and its suitability for conceptual and preliminary design of HALE aircraft.
