A manoeuvrable and relatively compact manned aircraft, which is intended for economic operation by means of providing a large component of the lift forces required by means of a buoyancy bag (or envelope) 1 containing a lighter than air gas, with the then relatively low residual lift and directional thrust required provided from a power driven source 7. There is a buoyancy bag with a people and machinery enclosure 2 underslung to provide stable operations. Lift and control thrust airflow created by fan 6 and controllable duct 8 pass through the body of the machine. |
