| 摘要 | A lighter-than-air aircraft having a central passageway longitudinal of the aircraft and a plurality of passageways radiating laterally therefrom. Suitable air moving means are located in said passageways near the forward end of the aircraft for drawing air into said passageways through the forward end thereof and supplying same under pressure to the rearward portion of said central passageway and to said radiating passageways. Suitable independently operated valving means on all of said passageways permit opening and closing of said selected ones thereof whereby said aircraft may be caused to move forwardly or stand still and may be further caused to move upwardly, downwardly or sidewardly. Reversing of said air moving means moves said aircraft rearwardly. Lifting gas is provided in a plurality of independent compartments, same being divided by a flexible diaphragm with lifting gas in one portion thereof and air in the other portion. By varying the proportion of air and lifting gas in selected ones or all of said compartments, the lift of the aircraft may be suitably adjusted or same may be trimmed. | ||||||
| 权利要求 | 1. A dirigible, comprising: means defining an elongated body; a plurality of mutually perpendicularly directed blast nozzles adjacent the forward and rearward portions of said elongated body means which open outwardly of said elongated body means, said blast nozzles being selectively operable independently of one another; means defining a drive passageway through the longitudinal center of said elongated body means between the nose and tail portions thereof and defining a supporting member, said drive passageway means being connected to provide air communication to said blast nozzles; at least one drive means being arranged in said drive passageway means, said drive means having suction port means adapted to draw air into one end of said drive passageway means and pressure port means adapted to discharge said air out of said other end, said suction port means including means defining a first passageway which extends concentrically of the drive passageway means along the length thereof a distance at least equal to the location of the largest diameter portion of said elongated body means; a plurality of hollow struts defining air passageways extending radially of said elongated body means and connected to said drive passageway means at the inner ends thereof, the outer ends of said air passageways each being open to the atmosphere, said radially extending hollow struts being grouped into selected radial planes spaced apart along the length of said drive passageway; said hollow struts including two groups of radial planes, a first group being longitudinally spaced over the front and center zone of said elongated body means, said first group being connected at their inner ends to said suction port means and said first passageway means to said drive means so that air is forcibly withdrawn from the front and center zone of said elongated body means, and said second group being longitudinally spaced over the rear zone of said elongated body means, said second group being connected at their inner ends in the zone adjacent the tail of said elongated body means to said pressure port means on said drive passageway means so that air is forcibly driven from said rear zone of said elongated body means whereby the pressure resistance developed at the front of said elongated body means is substantially reduced as same moves forwardly; and shell means forming the outer contour of said elongated body means having multiple longitudinal supports and circumferential frames, said circumferential frames being positioned in the radial planes of said hollow struts. 2. A dirigible according to claim 1, wherein the hollow struts are connected with the circumferential frames which have a groove extending around at least a portion of the outer surface of the elongated body means. 3. A dirigible according to claim 2, wherein the grooves extending around the circumferential frames are covered by perforated cover means. 4. A dirigible according to claim 3, wherein the perforations in the cover means are comprised of a chain of elongated openings, the longitudinal extension of which is transverse to the longitudinal axis of the elongated body means. 5. A dirigible according to claim 1, wherein the circumferential frames are provided on their outside with a groove extending therearound and that openings are provided which are tapered from the base of the groove, said grooves opening into a header into which said hollow struts open, whereby the header extends over a section corresponding to the distance between adjacent hollow struts. 6. A dirigible according to claim 1, wherein each of the hollow struts open respectively into the center of a header which extends over one section of said elongated body means and comprises tapered openings having a small cross section adjacent the hollow strut and increasing in cross section outwardly from the hollow strut. 7. A dirigible according to claim 1, including auxiliary drive means which drive impellers, for example propellers or axial compressors to supply pressurized air to said blast nozzles to steer said dirigible. 8. A dirigible according to claim 1, wherein said drive passageway means on one longitudinal end includes means dividing said drive passageway means into a plurality of separate passageways extending parallel to each other, the longitudinal ends of each of said parallel passageways being tapered. 9. A dirigible according to claim 1, wherein said rear zone on said elongated body means shortly before the tail unit comprises a stepped reduction in the diameter defining a flow-interrupting edge, the body portion adjacent the edge and extending rearwardly therefrom having a truncated conical shape. 10. A dirigible according to claim 1, wherein the depth of the stepped reduction in the diameter is approximately 2.75 percent of the larger diameter portion. 11. A dirigible according to claim 1, including means defining several separate compartments inside of the outer surface of the elongated body means along the longitudinal axis thereof, each of said compartments comprising an intermediate flexible wall to divide same into two subcompartments, one subcompartment containing a lifting gas and the other subcompartment being communicable with the atmosphere through a closable passage and a pump to permit a selective filling of said other subcompartment with air. 12. A dirigible according to claim 1, including tail landing gears pivotally secured to said elongated body means for movement about vertical axes. 13. A dirigible, comprising: means defining an elongated body having a nose and a tail unit; a plurality of mutually perpendicularly directed blast nozzles adjacent the forward and rearward portions of said elongated body means which open outwardly of said elongated body means, said blast nozzles being selectively operable independently of one another; means defining a drive passageway through the longitudinal center of said elongated body means between the nose and tail portions thereof; at least one drive means being arranged in said drive passageway means, said drive means having suction port means adapted to draw air into one end of said drive passageway means and pressure port means adapted to discharge said air out of said other end; a plurality of air passageways which open outwardly on said elongated body means along the length thereof; a plurality of first hollow struts interconnecting a first group of said air passageways to said suction port means to draw air into said first group of air passageways; a plurality of second hollow struts interconnecting a second group of said air passageways to said pressure port means to force air outwardly from said second group of said air passageways; a stepped reduction in the diameter of said elongated body means defining a flow interrupting edge intermediate the nose and tail units, the body adjacent the stepped edge and extending rearwardly therefrom having a truncated conical shape, said first group of said air passageways being positioned frontwardly of said stepped edge and said second group of said air passageways being positioned rearwardly from said stepped edge. 14. A dirigible according to claim 13, including valve means for controlling the air flowing through said first and second hollow struts. 15. A dirigible according to claim 13, Wherein said second group of air passageways includes means to direct the airflow rearwardly. |
