Aeroscraft
Worldwide Aeros Corp is an American manufacturer of airships based in Montebello, California. It was founded in 1993 by the current CEO and Chief Engineer, Igor Pasternak, who was born in Soviet Kazakhstan, raised in Soviet Ukraine, and moved to the U.S. after the Soviet collapse to build airships there. It currently employs more than 100 workers. The company's current products are non-rigids aimed at both the military and commercial markets, including transport, surveillance, broadcasting and advertising. The company's best-selling ship is called the Sky Dragon. The company is also developing an Aeroscraft, a rigid airship with a number of innovative features, the most important of which is a method of controlling the airship's static lift, which can be reduced by pumping helium from the internal gasbags and storing it under pressure: conversely lift can be increased by re-inflating the gasbags using the stored gas. The company has received $60 million from the U.S. Department ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dirigible
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] |

Rigid Airship
A rigid airship is a type of airship (or dirigible) in which the envelope is supported by an internal framework rather than by being kept in shape by the pressure of the lifting gas within the envelope, as in blimps (also called pressure airships) and semi-rigid airships. Rigid airships are often commonly called Zeppelins, though this technically refers only to airships built by the Luftschiffbau Zeppelin company. In 1900, Count Ferdinand von Zeppelin successfully performed the maiden flight of his first airship; further models quickly followed. Prior to the First World War, Germany was a world leader in the field, largely attributable to the work of von Zeppelin and his Luftschiffbau Zeppelin company. During the conflict, rigid airships were tasked with various military duties, which included their participation in Germany's strategic bombing campaign. Numerous rigid airships were produced and employed with relative commercial success between the 1900s and the late 1930s. The ...

WALRUS HULA
The Walrus HULA (Hybrid Ultra Large Aircraft) project was a DARPA-funded experiment to create an airship capable of traveling up to 12,000 nautical miles (about 22,000 km) in range, while carrying 500-1000 tons of air cargo. In distinct contrast to earlier generation airships, the Walrus HULA would be a heavier-than-air vehicle and would generate lift through a combination of aerodynamics, thrust vectoring, and gas buoyancy generation and management. DARPA said advances in envelope and hull materials, buoyancy and lift control, drag reduction and propulsion combined to make this concept feasible. Technologies to be investigated in the initial study phase included vacuum/air buoyancy compensator tanks, which provide buoyancy control without ballast, and electrostatic atmospheric ion propulsion. The WALRUS could potentially expand and speed the strategic airlift capability of the United States substantially while simultaneously reducing costs. A smaller scale demonstration was s ...

Marine Corps Air Station Tustin
Marine Corps Air Station Tustin (IATA: NTK, ICAO: KNTK, FAA LID: NTK) is a former United States Navy and United States Marine Corps air station, located in Tustin, California. History The Air Station was established in 1942 by the United States Navy as a lighter-than-air base, officially known as Naval Air Station Santa Ana. The base was designed for blimp operations in support of the Navy's coastal patrol efforts during World War II. It was commissioned on 1 October 1942 by its commandant, Capt. Howard N. Coulter. As of July 1947, the facility, under command of Capt. Benjamin May, had personnel consisting of 100 officers, 500 enlisted men and 180 civilian employees. NAS Santa Ana was decommissioned in 1949. In 1951, the facility was reactivated as Marine Corps Air Facility Santa Ana to support the Korean War. It was the country's first air facility developed solely for helicopter operations. It was renamed Marine Corps Air Station Tustin in 1979. During the Vietnam War, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dragon Dream
Dragon Dream (FAA registration: N866ML) is an experimental lighter than air (LTA) cargo rigid airship built by Worldwide Aeros Corp as a half-scale proof of concept prototype for a design which the manufacturer calls the "Aeroscraft". The development and design has been funded by the US government through the military Walrus HULA and then the "Pelican" projects. Design The hull of the Dragon Dream has a flattened elliptic cross-section. Buoyancy control is managed by pumping helium gas from the internal gas bag and compressing it into a storage cell, the reduction in lifting volume leading to a loss of buoyancy. The system can vary the airship's lift by 3,000–4,000 lb. The manufacturer uses the phrase "Control Of Static Heaviness" for this technology. ;Specifications Operational history The airship was completed in 2013 and, after extensive systems tests in the construction hangar, was granted an airworthiness certificate by the US Federal Aviation Administration T ...

Cargolifter AG
Cargolifter AG was a German company founded in 1996 to offer logistical services through point-to point transport of heavy and outsized loads. This service was based on the development of a heavy lift airship, the CL160, a vessel designed to carry a payload. The airship was never built and the company went bankrupt in July 2002. Today, shareholder-founded ''CL CargoLifter GmbH & Co. KG'' company seeks to continue selling the lighter-than-air technology. CargoLifter and Russia’s Aerosmena are among those developing huge airships that can lift up to 600 tons of freight while hovering above the ground or sea. Cargolifter AG was founded by a group of influential engineers and scientists in 1996, and its main goal was to promote airships and develop technologies for their use as a lifting mechanism for transporting heavy and bulky goods to hard-to-reach places. According to this idea, 1 m3 of helium is able to lift 1 kg of cargo, which means that when giving a large cylinder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
P-791
The Lockheed Martin P-791 is an experimental aerostatic and aerodynamic hybrid airship developed by Lockheed Martin. The first flight of the P-791 took place on 31 January 2006 at the company's flight test facility at United States Air Force Plant 42 in Palmdale, CA. Description The P-791 has a tri-hull shape, with disk-shaped cushions on the bottom for landing. As a hybrid airship, part of the weight of the craft and its payload are supported by aerostatic (buoyant) lift and the remainder is supported by aerodynamic lift. The combination of aerodynamic and aerostatic lift is an attempt to benefit from both the high speed of aerodynamic craft and the lifting capacity of aerostatic craft. History The P-791 was designed as part of the U.S. Army's Long Endurance Multi-intelligence Vehicle (LEMV) program, but lost the program's competition to Northrop Grumman's HAV-3 design. The P-791 was modified to be a civil cargo aircraft under the name SkyTug, with a lift capability of and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballast
Ballast is material that is used to provide stability to a vehicle or structure. Ballast, other than cargo, may be placed in a vehicle, often a ship or the gondola of a balloon or airship, to provide stability. A compartment within a boat, ship, submarine, or other floating structure that holds water is called a ballast tank. Water should move in and out from the ballast tank to balance the ship. In a vessel that travels on the water, the ballast will remain below the water level, to counteract the effects of weight above the water level. The ballast may be redistributed in the vessel or disposed of altogether to change its effects on the movement of the vessel. History The basic concept behind the ballast tank can be seen in many forms of aquatic life, such as the blowfish or members of the argonaut group of octopus. The concept has been invented and reinvented many times by humans to serve a variety of purposes. In the fifteenth and sixteenth century, the ballast "did not cons ...
