Design and dynamic modeling of a rotary wing aircraft with morphing capabilities

The aim of this paper is to introduce a multi-rotorcraft with morphing capabilities. Unlike conventional multi-copters whose body fly in a horizontal configuration, the proposed platform is be able to rotate its body into a vertical flying mode configuration. The research presented considers an 8-engine vehicle that is able to fly with 4-engines in case of rotor failure. The vertical flight mode is also intended for enabling navigation through narrow areas where conventional helicopter are too big to operate properly. Also, the convertible flight functionality allows saving battery if necessary. The dynamic model of the vehicle while performing in horizontal and vertical configurations is presented. An animated model shows the functionality of the vehicle while performing the transition maneuver.
