Special Issue Information

Dear Colleagues,

Unmanned aerial vehicles (UAVs) have been developed with various functions for many applications. However, due to the battery capacity and weight constraints, multi-rotors can have a very limited range in terms of mission distance and service time. Due to modern UAV/UAS requirements, hybrid power and dual mode VTOL and HTOL UAV/UAS aircraft are in high demand. A combination of multi-rotors with fixed wings is attractive because it enhances the payload and endurance, and increases maneuverability. Power supply on airborne UAVs can vary from batteries to additional systems such as gasoline generators, fuel cells, and solar panels. Designing hybrid power into UAVs will be valuable to future UAS developments. Beyond hybrid power, dual modes with VTOL and HTOL is another important subject to elevate UAS into wider applications. With advanced design for modern UAVs, these applications shall be interesting to both governments and industries. Industry–academic papers under the UAS Integrated Pilot Program (IPP) are welcome for submission, to share novel ideas, concepts, realizations, experiments, and applications.

Electric propulsion technology has attracted much attention in the aviation industry at present. It has the advantages of environmental protection, safety, low noise, and high design freedom. An important research branch of electric propulsion aircraft is electric vertical takeoff and landing (VTOL) aircraft, which is expected to play an important role in urban traffic in the future. Limited by battery energy density, all electric unmanned aerial vehicles (UAVs) are unable to meet the longer voyage. Series/parallel hybrid-electric propulsion and turboelectric propulsion are considered to be applied to VTOL UAVs to improve performances. In this paper, the potential of these four configurations of electric propulsion systems for small VTOL UAVs are evaluated and compared. The main purpose is to analyze the maximum takeoff mass and fuel consumption of VTOL UAVs with different propulsion systems that meet the same performance requirements and designed mission profiles. The differences and advantages of the four types propulsion VTOL UAV in the maximum takeoff mass and fuel consumption are obtained, which provides a basis for the design and configuration selection of VTOL UAV propulsion system.
