Design and joint control of a conjoined biplane and quadrotor

Unmanned Aerial Vehicles (UAVs) have the potential to perform many different missions, some of which may require a large aircraft for endurance and a small aircraft for manoeuvrability in a building. This paper proposes a novel combination of a quadrotor and a hybrid biplane capable of joint hover, joint forward flight, and mid-air disassembly...

Flight code convergence: fixedwing, rotorcraft, hybrid

Rotorcraft, fixed wing and hybrid Unmanned Air Vehicles (UAV) each have applications in which they excel. Traditionally, dedicated autopilot control code is written to accommodate flight of each UAV type. This causes fragmentation of control code and may lead to performance differences or errors. In this paper, we propose to use the same INDI...

Dual-axis tilting rotor quad-plane design, simulation, flight and performance comparison with a conventional quad-plane design

In the last few decades, the UAV research has been focusing on hybrid vehicles with Vertical Takeoff and Landing (VTOL) capabilities. Opposed to copters, hybrid vehicles are highly influenced by wind disturbances. This paper presents a novel quad-plane design that uses four dual-axis tilting rotors to enhance the wind rejection capability of...
