Rockoon
A rockoon (from ''rocket'' and ''balloon'') is a solid fuel sounding rocket that, rather than being immediately lit while 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. 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. Early atmospheric research ''Time'' magazine reported in 1959: "Van Allen's 'Rockoons' could not be fired in Iowa for fear that the spent rocket ...

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, Klaus Scheufelen 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 burs ...

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 Her hull was 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 icebreakers, was heavily ar ...

Balloon
A balloon is a flexible bag that can be inflated with a gas, such as helium, hydrogen, nitrous oxide, oxygen, and air. For special tasks, balloons can be filled with smoke, liquid water, granular media (e.g. sand, flour or rice), or light sources. Modern day balloons are made from materials such as rubber, latex, polychloroprene, or a nylon fabric, and can come in many different colors. Some early balloons were made of dried animal bladders, such as the pig bladder. Some balloons are used for decorative purposes or entertaining purposes, while others are used for practical purposes such as meteorology, medical treatment, military defense, or transportation. A balloon's properties, including its low density and low cost, have led to a wide range of applications. The rubber balloon was invented by Michael Faraday in 1824, during experiments with various gases. He invented them for use in the lab.

Air Launch To Orbit
Air launch to orbit (ALTO) is the method of launching smaller rockets at altitude from a heavier conventional horizontal-takeoff aircraft, to carry satellites to low Earth orbit. It is a follow-on development of air launches of experimental aircraft that began in the late 1940s. This method, when employed for orbital payload insertion, presents significant advantages over conventional vertical rocket launches, particularly because of the reduced mass, thrust, cost of the rocket, geographical factors and natural disasters. Air launching has also been developed for sub-orbital spaceflight. In 2004 the Ansari X Prize $10 Million purse was won by a team led by Burt Rutan's Scaled Composites, launching the SpaceShipOne from the purpose-built White Knight carrier aircraft. Advantages The principal advantage of a rocket being launched by a high flying airplane is that it needs not fly through the low, dense atmosphere, the drag of which requires a considerable amount of extra work ...

Deacon Rockoon
A deacon is a member of the diaconate, an office in Christian churches that is generally associated with service of some kind, but which varies among theological and denominational traditions. Major Christian churches, such as the Catholic Church, the Oriental Orthodox Churches, the Eastern Orthodox Church, the Scandinavian Lutheran Churches, the Methodist Churches, the Anglican Communion, and the Free Church of England, view the diaconate as an order of ministry. Origin and development The word ''deacon'' is derived from the Greek word (), which is a standard ancient Greek word meaning "servant", "waiting-man", "minister", or "messenger". It is generally assumed that the office of deacon originated in the selection of seven men by the apostles, among them Stephen, to assist with the charitable work of the early church as recorded in Acts of the Apostles chapter 6. The title ''deaconess'' ( grc, διακόνισσα, diakónissa, label=none) is not found in the Bible. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
