| Summary: | The present study focuses on the sizing and aerodynamic contour design of a two-seater
1000 kg gross take-off mass winged hybrid airship. Unlike the conventional hybrid airships,
which stay aloft and takeoff with the help of VTOL propulsion systems, a winged hybrid
airship requires a certain speed to takeoff by utilizing lift coming from its aerodynamic
surfaces. Heaviness fraction and takeoff ground roll are considered as measure of merit in
initial sizing. Based on the design requirement of Malaysian inter-island tourism and
transportation of agricultural products, range is set to 450 km and ground roll for take-off
about 150 m. For the airship to be heavy enough for ground handling, the ratio of
hydrostatic to hydrodynamic lift is set equal to 49:51. Summary of the results to be obtained
in early design phase will give a baseline start to study the aerodynamics and stability
characteristics of such airships in future. |
