The present invention relates to airships and more particularly to airships having internal or ducted propulsion systems.
Airships are well known, and have grown in popularity in recent years.
It is also well known that airships or dirigible type of aircraft are useful where quite, the ability to hover in one place for an extended period, and to land in un-developed areas are desired. Yet conventional designs are lacking for speed, efficiency, and maneuverability. And, that previous airship designs are slow, sluggush, inefficient and, incapable in high-wind gusts, and adverse weather.
Over the years there have been numerous improvements made to airships, and many designs to solve the problems described above.
These designs have generally been concentrated on the area of propulsion, and aerodynamics, yet the best designs do not adequately solve the problems of slow, sluggush, inefficient, and high-wind-gust, and adverse-weather incapability to a satisfactory degree.
U.S. Pat. No. 6,607,163 discloses a conventional conical straight tubular shaped airship with near space buoyancy and propulsion means however it does not have a tubular straight fuselage, non-protruding attitudinal control wings, air deflector cones, an inner air passageway, internal propulsion means, or outer atmospheric propulsion & attitudinal control means.

No. 5,071,090 shows a conventional conical straight tubular shaped airship with an internal air passageway, and internal propulsion means, however it does not have a tubular straight fuselage, non-protruding attitudinal control wings, air deflector cones, or outer atmospheric propulsion & attitudinal control means.
U.S. Pat. No. 4,967,983 describes an airfoil type airship with an internal air passageway, however it does not have a tubular straight fuselage, non-protruding attitudinal control wings, air deflector cones, or outer atmospheric propulsion & attitudinal control means.
U.S. Pat. No. 1,835,260 shows a conventional conical straight tubular shaped airship with an internal air passageway, and internal propulsion means, however it does not have a tubular straight fuselage, non-protruding attitudinal control wings, air deflector cones, or outer atmospheric propulsion & attitudinal control means.
U.S. Pat. No. 2,384,893 shows an airfoil airship having an internal air passageway however it does not have a tubular straight fuselage, non-protruding attitudinal control wings, air deflector cones, or outer atmospheric propulsion & attitudinal control means.
U.S. Pat. No. 3,288,397 shows a tri-hull airship airfoil with conventional elliptical shaped airship fuselages affixed together comprising an air-ship airfoil, having external control apertures and external propulsion means however it does not have a tubular straight fuselage, non-protruding attitudinal control wings, air deflector cones, an inner air passageway, an internal propulsion means, or outer atmospheric propulsion & attitudinal control means.
A main advantage of the present invention is providing an improved airship that attempts to solve the problems of conventional airships detailed herein by incorporating one or more of the characteristics discussed in the embodiments listed below.
Accordingly several advantages of one or more aspects of the present invention are to provide an airship having improved speed performance, maneuverability, efficiency, and adverse weather capability.
It is a further an advantage of the invention to provide an airship with reduced air displacement, forward air resistance, and rearward drag of the airship.
It is another advantage of the invention to provide an airship with improved airflow direction into, out of, and around the airship.
It is yet another advantage of the invention to provide an airship with improved attitudinal, directional, pitch, roll, & yaw, control, further improved airflow control into, out of, and around the airship.
It is still another advantage of the invention to provide an improved airship with propulsive, attitudinal & directional control in space, air atmosphere, and transition to and from thereof. The foregoing and other advantages are realized by providing a linear straight tubular shaped fuselage, having an inner air passageway axially extending therethrough tapering inwardly from the furthest circumferential peripheral exterior edges of the fuselage fore, toward the interior mid region of the airship like a funnel, forming an air inlet in the fuselage fore, which then connects to the inner air passageway; propelling air into and out of the airship is the propulsion system located inside the inner air passageway which extends downstream and continues to the airship aft tapering outwardly like a funnel to the furthest circumferential peripheral exterior edges of the fuselage aft forming an air outlet in the aft of the fuselage. This causes air to be transported from the front of the airship, into and through the inner air passageway out of and behind the airship, thereby moving the airship through the air.
The straight tubular shaped fuselage also having a plurality of air deflector cones axially centrally positioned substantially inside and extending from the air inlet and outlet openings fore and aft in the fuselage, connectably affixed to the air inlet funnel and fuselage which direct airflow into and out of the airship to the circumferential peripheral regions of the air inlet and outlet openings, into, out-of, & through the inner air passageway which extends axially through the fuselage, thereby directing the airflow into, through, and out of the airship fuselage. The plurality of airship deflector cones further providing containment for a plurality of lighter than air resilient gas bags thereby providing static lift further adding to the airships buoyancy Further a plurality of bifurcated active and non active winged control surfaces located at the fore and aft of the air inlet and outlet inner air way openings. The winged control surfaces being positioned horizontally and vertically across the inner air way openings, having the active control surfaces being rotatably hingably attached to the non active control surfaces, and a plurality of actuators attached between the air intake and air outlet sections of the fuselage and to the control surfaces thereby operably, rotatably, actuating the hinged active control surfaces respective to their non active control surfaces.
Thereby operably controlling direction of air flow into the air inlet opening and out of the air outlet opening; controlling direction, pitch, roll and yaw, of the airship.
The result is an improved airship having reduced air displacement, forward air resistance, rearward drag, fuel economy, speed performance, maneuverability, efficiency, and adverse weather capability.
