01 - Aircraft Design and Integrated SystemsRESEARCH ON DESIGN METHOD OF PETROL-ELECTRIC HYBRID DRIVE SYSTEM BASED ON MDO FOR A NOVEL VTOVL UAVZ.X. Yao, Shenyang Aircraft Design and Research Institute, China The UAV has a novel tailless aerodynamic shap with large aspect ratio wings and four fans driven by Petrol-Electric Hybrid System for VTOVL. It is expected for the UAV to optimize the time of level and hovering flight, by allocating the weight of battery and fuel. |
