Aereon Dynairship
The Aereon Dynairship is a conceptual large hybrid airship developed by the AEREON, Aereon Corporation for civilian and military cargo transport. It is one of Aereon's lifting body airship concepts, where a craft without a conventional "wing" generates lift by itself. It would have also have been filled with buoyant gas such as preferably helium or hydrogen, but possibly heated gases, making it a truly hybrid craft. This kind of configuration was researched by Aereon beginning in the 1960s and continuing until the 1980s. Several patent applications were filed, including a patent application filed in 1969. The early development of the deltoid pumpkinseed aerobody was described in a John McPhee 1973 book. Design and development The Dynairship was to be a very large ship, the conceptual designs showing it to form a large triangle, with small finlets at the back of either end. The proof-of-concept aircraft for the Dynairship was the Aereon 26. Following the apparent success of this pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lifting Body
A lifting body is a fixed-wing aircraft or spacecraft configuration in which the body itself produces lift. In contrast to a flying wing, which is a wing with minimal or no conventional fuselage, a lifting body can be thought of as a fuselage with little or no conventional wing. Whereas a flying wing seeks to maximize cruise efficiency at subsonic speeds by eliminating non-lifting surfaces, lifting bodies generally minimize the drag and structure of a wing for subsonic, supersonic and hypersonic flight, or spacecraft re-entry. All of these flight regimes pose challenges for proper flight safety. Lifting bodies were a major area of research in the 1960s and 70s as a means to build a small and lightweight crewed spacecraft. The US built a number of lifting body rocket planes to test the concept, as well as several rocket-launched re-entry vehicles that were tested over the Pacific. Interest waned as the US Air Force lost interest in the crewed mission, and major development ended ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Of America
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations.

Hybrid Airship
A hybrid airship or plimp is a powered aircraft that obtains some of its lift as a lighter-than-air (LTA) airship and some from aerodynamic lift as a heavier-than-air aerodyne. A ''dynastat'' is a hybrid airship with fixed wings and/or a lifting body and is typically intended for long-endurance flights. It requires forward flight to create the aerodynamic lift component. A ''rotastat'' is a hybrid airship with rotary wings and is typically intended for heavy lift applications. Its rotary wings can provide lift even when hovering or manoeuvring vertically, like a helicopter. No production designs have been built, but several manned and unmanned prototypes have flown. The term "hybrid airship" has also been used to describe an airship comprising a mix of rigid, semi-rigid, and non-rigid construction. Features Conventional airships have low operating costs because they need no engine power to remain airborne, but are limited in several ways, including low payload/volume ratio ...

Aereon 26
The AEREON 26 was an experimental aircraft developed to investigate lifting body design with a view to using its shape to create hybrid designs, part airship, part conventional aircraft. It was powered by a piston engine, driving a pusher propeller, and generated lift through the aerodynamics of its lozenge-shaped fuselage. Although results of flight tests conducted in 1971 were promising, funding for larger and semi-buoyant aircraft was not forthcoming at the time. The story of the test program was recounted by John McPhee in his book ''The Deltoid Pumpkin Seed'' (). This aircraft has a special place in UFO and conspiracy lore, since enthusiasts have drawn parallels between the shape of this aircraft and some reported UFOs from around the same era. Background The AEREON Corporation, established in 1959, at first concentrated on the construction of a prototype three-hull hybrid airship, the '' AEREON III''. Completed in 1965, the prototype was lost during taxiing tests the fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed Martin Aeronautics
Lockheed Martin Aeronautics Company is a major unit of Lockheed Martin with headquarters at Air Force Plant 4 in Fort Worth, Texas. Lockheed Martin Aeronautics is based in Marietta, Georgia and Palmdale, California. Palmdale is home to the Advanced Development Programs (ADP), informally known as the "Skunk Works". Various subassemblies are produced at locations in Florida, Mississippi, Pennsylvania, and West Virginia. The company draws upon the history of the former Lockheed and Martin Marietta corporations. While the formation of Lockheed Martin in 1995 was a merger of equals, by far the greatest contribution to Lockheed Martin Aeronautics was the product portfolio of Lockheed. This included the C-5, C-130, and C-141 transports as well as the F-2, F-16 (purchased from General Dynamics), F-117, F-22, and F-35 Lightning II. The most important project by far to Lockheed Martin Aeronautics is the F-35 Lightning II (JSF). Worth a potential $200bn the initial order book ...

Airships Of The United States
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airships in that country. Most airships built since the 1960s have used helium, though some have used hot air.A few airships after World War II used hydrogen. The first British airship to use helium was the ''Chitty Bang Bang'' of 1967. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An airship also has engines, crew, and optionally also payload accommodation, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1970s United States Experimental Aircraft
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * February 19 – Battle of Lugdunum: Emperor Septimius Severus defeats the self-proclaimed emperor Clodius Albinus at Lugdunum (modern Lyon). Albinus commits suicide; legionaries sack the town. * Septimius Severus returns to Rome and has about 30 of Albinus's supporters in the Senate executed. After his victory he declares himself the adopted son of the late Marcus Aurelius. * Septimius Severus forms new naval units, manning all the triremes in Italy with heavily armed troops for war in the East.

Pusher Aircraft
In an aircraft with a pusher configuration (as opposed to a tractor configuration), the propeller(s) are mounted behind their respective engine(s). Since a pusher propeller is mounted behind the engine, the drive shaft is in compression in normal operation. Pusher configuration describes this specific (propeller or ducted fan) thrust device attached to a craft, either aerostat (airship) or aerodyne (aircraft, WIG, paramotor, rotorcraft) or others types such as hovercraft, airboat and propeller-driven snowmobiles. "Pusher configuration" also describes the layout of a fixed-wing aircraft in which the thrust device has a pusher configuration. This kind of aircraft is commonly called a pusher. Pushers have been designed and built in many different layouts, some of them quite radical. History The rubber-powered "Planophore", designed by Alphonse Pénaud in 1871, was an early successful model aircraft with a pusher propeller. Many early aircraft (especially biplanes) were ...
