Summary:This paper proposes an innovative coaxial aircraft with tandem ducted fans, which has great trafficability and is particularly suitable for passing through narrow spaces. The unconventional structure leads to unknown complicated dynamical characteristics. A comprehensive nonlinear dynamic model is established, considering the special characteristics of duct and coaxial rotors. On this basis, a series of modeling analyses are completed to fully understand the coupling, stability and controllability of the aircraft. The results verify the feasibility of this innovative design and reveal the dynamic differences between it and other conventional aircrafts. Moreover, the results are the prerequisite for future controller design and provide guidance for the controller design process.
