A winged hybrid airship (dynastat) combining the advantages of lighter-than-air (LTA) and heavier-than-air (HTA) aircrafts is disclosed. By combining the dynamic lift of low drag, high aspect ration airfoils (e.g., length over chord >10) with the static lift of low drag, laminar-airflow airships, a
A winged hybrid airship (dynastat) combining the advantages of lighter-than-air (LTA) and heavier-than-air (HTA) aircrafts is disclosed. By combining the dynamic lift of low drag, high aspect ration airfoils (e.g., length over chord >10) with the static lift of low drag, laminar-airflow airships, a platform is formed which is capable of prolonged high altitude flight, maintaining station over a given point on the earth, carrying a payload of communications, reconnaissance or meteorological equipment. Solar collection cells and microwave antennas allow for recharging of on board batteries/fuel cells for powering both the airship and on board avionics computers and reconnaissance or meteorological equipment. An alternate embodiment, having strengthened structural members, is able to provide low altitude heavy cargo lift in remote regions regions or cross country transport of goods.

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 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 is higher than the predetermined temperature, said second heat generating element does not generate heat, but said first heat generating element generates heat. 13. An image heating apparatus according to claim 12, 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. 14. An image heating apparatus according to claim 12, 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. 15. An image heating apparatus for heating an image on a recording material, comprising: a heating member; a plurality of heat generating elements mounted on said heating member; transfer control means for controlli
