Entrepreneurship
Since 1994, Pasternak's entrepreneurial and engineering career in the US has been closely associated with Worldwide Aeros Corp
(alternatively known as Aeros), [12] the company he re-established in the US. [10] In 1994, Pasternak moved from New York to California and leased a hangar from the Castle Air Force Base (located two hours south of San Francisco) to build his first airship in the US - Aeros 50, a seventy-eight-foot long blimp. Aeros 50 was later sold for advertising during the 1996 Paralympic Games. [6] [18] Since then, Aeros has released and launched into serial production a number of new airship models including the Sky Dragon, the cargo airship Dragon Dream (Aeroscraft) and Tethered Aerostat System (TAS) among others. Worldwide Aeros Corp received various certifications including from Federal Aviation Administration (FAA) for some of its airships. [12] [19] The company subsequently moved its building operation to Montebello, California, where it is located now. [17] [6] [2]
Joint projects with the US government
Pasternak's company R&D has been intensively funded by the US government. Aeros signed contracts with The Pentagon through DARPA's project Walrus HULA [3] and the Rapid Reaction Technology Office on building reconnaissance and cargo military airships, [10] [20] [21] including $50 million project for the development of the Pelican prototype. [22] [23] In 2013, Pasternak led development and construction of Aeroscraft Dragon Dream, the first airship independent from ballast during cargo loading and able to conduct vertical take off and landing at fully load. In September 2013, after being cleared by the FAA, the Dragon Dream had its first tethered flight in Tustin, California. [9] [24] [25] In 2014, Pasternak and his company supplied Ukraine with the identification signal system in the Azov sea. [18] [14]
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, helicopters, airships, gliders, paramotors, and hot air balloons.
A blimp, or non-rigid airship, is an airship (dirigible) without an internal structural framework or a keel. Unlike semi-rigid and rigid airships, blimps rely on the pressure of the lifting gas inside the envelope and the strength of the envelope itself to maintain their shape.
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.
The Zeppelin NT is a class of helium-filled airships being manufactured since the 1990s by the German company Zeppelin Luftschifftechnik GmbH (ZLT) in Friedrichshafen. The initial model is the N07. The company considers itself the successor of the companies founded by Ferdinand von Zeppelin which constructed and operated the very successful Zeppelin airships in the first third of the 20th century. There are, however, a number of notable differences between the Zeppelin NT and original Zeppelins as well as between the Zeppelin NT and usual non-rigid airships known as blimps. The Zeppelin NT is classified as a semi-rigid airship.
An aerostat is a lighter-than-air aircraft that gains its lift through the use of a buoyant gas. Aerostats include unpowered balloons and powered airships. A balloon may be free-flying or tethered. The average density of the craft is lower than the density of atmospheric air, because its main component is one or more gasbags, a lightweight skin containing a lifting gas to provide buoyancy, to which other components such as a gondola containing equipment or people are attached. Especially with airships, the gasbags are often protected by an outer envelope.
Frederick Karl Gampper Jr. was a dirigible pilot with license #53 issued by the Aero Club of America, and a licensed free balloon pilot. His mentors included Ralph H. Upson and Herman Kraft.
A hybrid airship 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.
The G-Class Blimps were a series of non-rigid airships (blimps) used by the United States Navy. In 1935, instead of developing a new design airship, the Navy purchased the Goodyear Blimp Defender for use as a trainer and utility airship assigning it the designator G-1. Defender was built by the Goodyear Aircraft Company of Akron, Ohio and was the largest blimp in the company’s fleet of airships that were used for advertising and as passenger airships. Goodyear built additional G-class airships for the Navy during World War II to support training needs.
The N-Class, or as popularly known, the "Nan ship", was a line of non-rigid airships built by the Goodyear Aircraft Company of Akron, Ohio for the US Navy. This line of airships was developed through many versions and assigned various designators as the airship designation system changed in the post World War II era. These versions included airships configured for both anti-submarine warfare and airborne early warning (AEW) missions.
The Walrus HULA project was a DARPA-funded experiment to create an airship capable of traveling up to 12,000 nautical miles 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.
A thermal airship is an airship that generates buoyancy by heating air in a large chamber or envelope. The lower density of interior hot air compared to cool ambient air causes an upward force on the envelope. This is very similar to a hot air balloon, with the notable exception that an airship has a powered means of propulsion, whilst a hot air balloon relies on winds for navigation. An airship that uses steam would also qualify as a thermal airship.
Goodyear Aerospace Corporation (GAC) was the aerospace and defense subsidiary of the Goodyear Tire and Rubber Company. The company was originally operated as a division within Goodyear as the Goodyear Zeppelin Corporation, part of a joint project with Luftschiffbau Zeppelin, leading to the development of rigid airships in the United States. As part of the failing relationship between the US and Germany in the era prior to World War II, the division was spun off as Goodyear Aircraft Company in 1939. The company opened a new factory in Arizona in 1941 which produced subassemblies, including subcontracted airframe construction and the design of the Goodyear F2G Corsair and Goodyear Duck.
A semi-rigid airship is an airship which has a stiff keel or truss supporting the main envelope along its length. The keel may be partially flexible or articulated and may be located inside or outside the main envelope. The outer shape of the airship is maintained by gas pressure, as with the non-rigid "blimp". Semi-rigid dirigibles were built in significant quantity from the late 19th century but in the late 1930s they fell out of favour along with rigid airships. No more were constructed until the semi-rigid design was revived by the Zeppelin NT in 1997.
Marine Corps Air Station Tustin is a former United States Navy and United States Marine Corps air station, located in Tustin, California.
Aeros Corp is an American manufacturer of airships based in Los Angeles, 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 static buoyancy of airships in flight is not constant. It is therefore necessary to control the altitude of an airship by controlling its buoyancy: buoyancy compensation.
Airship Industries was a British manufacturers of modern non-rigid airships (blimps) active under that name from 1980 to 1990 and controlled for part of that time by Alan Bond. The first company, Aerospace Developments, was founded in 1970, and a successor, Hybrid Air Vehicles, remains active as of 2022. Airship Industries itself was active between 1980 and 1990.
The Hybrid Air Vehicles Airlander 10 is a hybrid airship designed and built by British manufacturer Hybrid Air Vehicles (HAV). Comprising a helium airship with auxiliary wing and tail surfaces, it flies using both aerostatic and aerodynamic lift and is powered by four diesel engine-driven ducted propellers.
The AeroLift CycloCrane was a unique US hybrid airship which adopted helicopter derived airfoil control for low speed flight manoeuvring by spinning on its axis. It was intended to be a heavy load lifter, initially aimed at the Canadian logging industry. A proof of concept vehicle flew at times during the 1980s, but no large production aircraft were built.
Dragon Dream 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.
