Rockoon
A rockoon (from ''rocket'' and ''balloon'') is a sounding rocket that, rather than being lit immediately while still on the ground, is first carried into the upper atmosphere by a gas-filled balloon, then separated from the balloon and ignited. This allows the rocket to achieve a higher altitude, as the rocket does not have to move under power through the lower and thicker layers of the atmosphere. A 2016 study by '' Acta Astronautica'' concluded that low-mass and high altitude launches give the best results. The original concept was developed by Cmdr. Lee Lewis, Cmdr. G. Halvorson, S. F. Singer, and James A. Van Allen during the Aerobee rocket firing cruise of the U.S.S. ''Norton Sound'' on March 1, 1949. A serious disadvantage is that unpiloted balloons cannot be steered, and consequently the location from which the rocket is launched can be uncertain. Therefore, a large area for the fall of the rocket is required for safety reasons. The rockoons that Robert Ellis worked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deimos-One
Deimos-One is an American spaceflight technology development company working on an AI powered, autonomous UAV rocket system to move payloads to space. As of January 2021, the company has completed a successful prototype test flight, reaching an altitude of . History Deimos-One was founded in 2020 by Jamin Thompson in Las Vegas, Nevada. The company's current headquarters are in Summerlin, Nevada. In 2021, Deimos-One continued development of its 150,000 square-foot corporate headquarters in southern Nevada and test flight facility. Technology Deimos-One is developing a stratospheric UAV powered space launch system that intends to reduce dependency on traditional chemical rockets, with the goal of lowering the cost of access to space while increasing the frequency of launch. The technology uses a first-stage balloon to lift the launch vehicle to a pre-programmed altitude. The rocket ignites its engines once the launch craft reaches a altitude and then inserts the payload in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deacon (rocket)
Deacon is the designation of an American sounding rocket. The Deacon was launched 90 times from 1947 to 1957 from Wallops Island, and it also was the rocket portion of the first rockoons, launched 1952 to 1956. The Deacon has a maximum flight height of 20 kilometers and a payload ability of 17 kilograms. The takeoff thrust of the Deacon amounts to 27 kN, the takeoff weight In science and engineering, the weight of an object is a quantity associated with the gravitational force exerted on the object by other objects in its environment, although there is some variation and debate as to the exact definition. Some sta ... 93 kg, the diameter 0.16 m and the length 3.28 m. Triple Deacon The Triple Deacon was a single stage member of the Deacon family that used three Deacon booster motors. Five launches from NASA's Wallops Flight Facility occurred in 1953. References {{Cajun rockets 1953 in spaceflight Sounding rockets of the United States ...

Zero2infinity
Zero 2 Infinity (0II∞, sometimes rendered as Zero2Infinity) is a private Spanish company developing high-altitude balloons intended to provide access to near space and low Earth orbit using a balloon-borne pod and a balloon-borne launch vehicle, launcher. The company was founded in 2009 by aerospace engineer Jose Mariano López-Urdiales, the current CEO. It is headquartered in Barberà del Vallès, Barcelona, Spain. Zero 2 Infinity has been testing high-altitude balloons and launching small payloads to high altitudes for scientific institutions and commercial firms for testing elements above most of the Earth's atmosphere. Their launch system has a significantly lower impact on the environment, an advantage over conventional systems. The company's pod named Bloon may also be used for tourism. In late 2016, its CEO had suggested that commercial flights could take place as early as 2019. As of 2020, the company aims to carry paying passengers to above 30 km altitude by 20 ...

JP Aerospace
JP Aerospace is an American company that aims to achieve affordable access to space. Their main activities include high-atmospheric lighter-than-air flights carrying cameras or miniature experiments called PongSats and minicubes. They are also engaged in an Airship to Orbit project. JP Aerospace was founded by John Marchel Powell, familiarly known as "JP", with Michael Stucky and Scott Mayo. JP Aerospace specializes in lighter-than-air flight, with the stated aim of achieving cheap access to space.Powell, John M. (2005). ''Floating to Space: The Airship to Orbit Program'', Apogee Books Space Series. Balloon flights An early suborbital space launch attempt using a rockoon (balloon-launched high power rocket) at the Black Rock Desert in northwestern Nevada in May 1999 was unsuccessful.

Da Vinci Project
The da Vinci Project was a privately funded, volunteer-staffed attempt to launch a reusable crewed sub-orbital spacecraft. It was formed in 1996 specifically to be a contender for the Ansari X Prize for the first non-governmental reusable crewed spacecraft. The project was based in Toronto, Ontario, Canada and led by Brian Feeney. The original da Vinci Project is no longer operating. A documentary was filmed throughout much of the project's life from 2000 through post-X Prize roundup footage in 2008. The documentary accumulated some 1000 hours or so of footage. It was a private undertaking by Michel Jones of Riverstone Productions, Toronto, and as of early 2009 was still in a preliminary stage of editing and completion. The project last participated in the X Prize Cup 2005, displaying a mock-up of its Wild Fire MK Vl spacecraft. Spacecraft design The project's design was a rocket-powered spacecraft to be air-launched from a helium balloon at an altitude of about 21 km (6 ...

USCGC Eastwind (WAGB-279)
USCGC ''Eastwind'' (WAGB-279) was a ''Wind''-class icebreaker that was built for the United States Coast Guard. Completed in time to see action in World War II, she continued in USCG service under the same name until decommissioned in 1968. Construction ''Eastwind'' was the second of five Wind-class of icebreakers built for the United States Coast Guard. Her keel was laid down on 23 June 1942 at Western Pipe and Steel Company shipyards in San Pedro. She was launched on 6 February 1943 and commissioned on 3 June 1944.Silverstone, Paul H.(1965): ''U.S. Warships of World War II''. Doubleday and Company, pg. 378 Wind-class icebreakers had hulls of unprecedented strength and structural integrity, with a relatively short length in proportion to the great power developed, a cut away forefoot, rounded bottom, and fore, aft and side heeling tanks. Diesel electric machinery was chosen for its controllability and resistance to damage. ''Eastwind'', along with the other Wind-class icebrea ...

Loki (rocket)
Loki, officially designated 76mm HEAA Rocket T220, was an American unguided anti-aircraft rocket based on the German Taifun. Like the Taifun, Loki never saw service in its original role, but later found widespread use as a sounding rocket. It was so successful in this role that several advanced versions were developed on the basic Loki layout, including the final Super Loki. Development As part of their anti-aircraft development program of 1942, the ''Luftwaffe'' began developing a number of guided missile projects. However, there was concern that these would not develop in time to be useful in the 1943/44 time frame. To fill the gap, suggested building a simple unguided rocket that would be fired en-masse directly up into the bomber streams. The result was the Taifun. Taifun was powered by a hypergolic mixture pressure-fed into the combustion chamber. The pressure was provided by small cordite charges that were fired into the fuel tanks, in the process bursting a pair of thin ...

Sounding Rocket
A sounding rocket or rocketsonde, sometimes called a research rocket or a suborbital rocket, is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight. The rockets are often used to launch instruments from above the surface of the Earth, the altitude generally between weather balloons and satellites; the maximum altitude for balloons is about and the minimum for satellites is approximately . Due to their suborbital flight profile, sounding rockets are often much simpler than their counterparts built for orbital flight. Certain sounding rockets have an apogee between , such as the Black Brant X and XII, which is the maximum apogee of their class. For certain purposes, sounding rockets may be flown to altitudes as high as to allow observing times of around 40 minutes to provide geophysical observations of the magnetosphere, ionosphere, thermosphere, and mesosphere.
