Experimental Evaluation of a Quadrotor Biplane with Variable Pitch Rotors
Proceedings of the Vertical Flight Society 73rd Annual Forum and Technology Display, 2017Vertical Takeoff and Landing (VTOL) capable air vehicles such as quadcopters are being chosen for missions requiring higher payload capacities, longer endurance in hover, longer range, and most importantly faster travel time. To meet this need, hybrid air vehicles that incorporate the design features of fixed wing vehicles and rotorcraft have come to ...

Modeling and Trajectory Control of a Transitioning Quadrotor Biplane Tailsitter
Proceedings of the Vertical Flight Society 75th Annual Forum and Technology Display, 2019A comparison study between modeling approaches of a quadrotor biplane tailsitter aircraft is conducted. A blade element theory model with dynamic inflow is used to validate a reduced order model that incorperates a simple interference model for trajectory planning and dynamic simulation.
