A circular VTOL aircraft with a central vertically mounted turboprop engine (14), driving contra-rotating co-axial propellers (24), above a central jet engine, or engines (12), horizontally mounted on a turntable pod (11) which is steerable through 360 degrees. The turboprop provides vertical thrust
A circular VTOL aircraft with a central vertically mounted turboprop engine (14), driving contra-rotating co-axial propellers (24), above a central jet engine, or engines (12), horizontally mounted on a turntable pod (11) which is steerable through 360 degrees. The turboprop provides vertical thrust from contra-rotating propellers compressing air from an upper circular intake (5) downward through a funnel-shaped rotor-chamber (6) to a circular vent (10) at the base of the craft. The resulting column of compressed air supports the craft during take-off, hover and landing operations and provides a cushion of air in normal flight. The horizontally mounted jet turbine provides main thrust for horizontal flight and vectored thrust for VTOL. The passenger cabin (21) is circular and is situated in the main body of the disc-shaped craft. Fuel tanks are situated around the circumference of the craft to maximise fuel capacity. The flight-deck (2) is situated at the top center of the craft, above the engine unit (15), which is detachable.

An image heating apparatus according to claim 1, wherein said power supply control means supplies electric power to said first and second heat generating elements irrespective of the number of passing recording materials when the detected temperature is lower than a predetermined temperature, and cuts off the electric power supply to said second heat generating element when the detected temperature becomes higher than the predetermined temperature and the number of passing recording materials becomes greater than a predetermined number. 3. An image heating apparatus according to claim 2, wherein said second heat generating element is disposed downstream of said first heat generating element with respect to a direction of movement of the recording material. 4. An image heating apparatus according to claim 2, wherein lengths of said first and second heat generating elements in a longitudinal direction thereof are substantially equal to each other. 5. An image heating apparatus according to claim 2, wherein a length of said second heat generating element in a longitudinal direction thereof is greater than that of said first heat generating element. 6. An image heating apparatus according to claim 1, further comprising a film adapted to be moved while contacting with said heating member, and wherein said heating member heats the image through said film. 7. An image heating apparatus for heating an image on a recording material, comprising: a heating member; a first heat generating element mounted on said heating member; and a second heat generating element mounted on said heating member; wherein when a temperature of an area of said heating member where the recording material of a predetermined minimum size does not pass is lower than a predetermined temperature, said first and second heat generating elements generate heat, and when the temperature of the area becomes higher than the predetermined temperature and number of continuously passing recording materials becomes greater than a predetermined number, said first heat generating element continues to generate heat and said second heat generating element stops generating heat. 8. An image heating apparatus according to claim 7, wherein said second heat generating element is disposed downstream of said first heat generating element with respect to a direction of movement of the recording material. 9. An image heating apparatus according to claim 7, wherein lengths of said first and second heat generating elements in a longitudinal direction thereof are substantially equal to each other. 10. An image heating apparatus according to claim 7, wherein a length of said second heat generating element in a longitudinal direction thereof is greater than that of said first heat generating element. 11. An image heating apparatus according to claim 7, further comprising a film adapted to be moved while contacting with said heating member, and wherein said heating member heats the image through said film. 12. An image heating apparatus for heating an image on a recording material, comprising: a heating member; a first heat generating element mounted on said heating member; a second heat generating element mounted on said heating member, a width of said second heat generating element in a longitudinal direction thereof being substantially equal to that of said first heat generating element; wherein when a temperature of an area of
