Practical implicationsUsing ABC algorithm provides to improve the value of thrust–torque ratio of an unmanned helicopter. With this algorithm, unmanned helicopter flies more than ever. Thus, the presented method based on the ABC algorithm is more efficient.Social implicationsThe application of the ...

As is known, the comparatively bigger size (e.g., volume, cross and side area) to inertia ratio typical of airships tends to exacerbate stability and controllability issues, compared to other flying machines [11,12,13,14,15], in turn making flight for this class of aircraft potentially mu...
