Novel semi-analytical methods for flutter eigenvalues sensitivity analysis with respect to the shape has been developed. The derivative of all the structural matrices has been calculated analytically with an element-agnostic approach, while aerodynamic matrices have been differentiated using finite differences. The methods allow for a more accurate and efficient aeroelastic shape sensitivity analysis.
