Aerojet was an American rocket and missile propulsion manufacturer based primarily in Rancho Cordova, California, with divisions in Redmond, Washington, Orange and Gainesville in Virginia, and Camden, Arkansas. Aerojet was owned by GenCorp, Inc., In 2013, Aerojet was merged by GenCorp with the former Pratt & Whitney Rocketdyne to form Aerojet Rocketdyne. History Aerojet developed from a 1936 meeting hosted by Theodore von Kármán at his home. Joining von Kármán, who was at the time director of Guggenheim Aeronautical Laboratory at the California Institute of Technology, were a number of Caltech professors and students, including rocket scientist and astrophysicist Fritz Zwicky and explosives expert Jack Parsons, all of whom were interested in the topic of spaceflight. The group continued to occasionally meet, but its activities were limited to discussions rather than experimentation. Their first design was tested on August 16, 1941, consisting of a small cylindrical solid-f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manufacturer
Manufacturing is the creation or Production (economics), production of goods with the help of equipment, Work (human activity), labor, machines, tools, and chemical or biological processing or formulation. It is the essence of the secondary sector of the economy. The term may refer to a range of Human behavior, human activity, from handicraft to High tech manufacturing, high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector of the economy, primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, Major appliance, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USAAF
The United States Army Air Forces (USAAF or AAF) was the major land-based aerial warfare service component of the United States Army and ''de facto'' aerial warfare service branch of the United States during and immediately after World War II (1941–1947). It was created on 20 June 1941 as successor to the previous United States Army Air Corps and is the direct predecessor of the United States Air Force, today one of the six United States Armed Forces, armed forces of the United States. The AAF was a component of the United States Army, which on 2 March 1942 was divided functionally by executive order into three autonomous forces: the Army Ground Forces, the United States Army Services of Supply (which in 1943 became the Army Service Forces), and the Army Air Forces. Each of these forces had a commanding general who reported directly to the Chief of Staff of the United States Army, Army Chief of Staff. The AAF administered all parts of military aviation formerly distributed am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Project Gemini
Project Gemini () was the second United States human spaceflight program to fly. Conducted after the first American crewed space program, Project Mercury, while the Apollo program was still in early development, Gemini was conceived in 1961 and concluded in 1966. The Gemini spacecraft carried a two-astronaut crew. Ten Gemini crews and 16 individual astronauts flew low Earth orbit (LEO) missions during 1965 and 1966. Gemini's objective was the development of space travel techniques to support the Apollo mission to Moon landing, land astronauts on the Moon. In doing so, it allowed the United States to catch up and overcome the lead in human spaceflight capability the Soviet Union had obtained in the early years of the Space Race, by demonstrating mission endurance up to just under 14 days, longer than the eight days required for a round trip to the Moon; methods of performing extravehicular activity (EVA) without tiring; and the orbital maneuvers necessary to achieve space rendezv ...

Titan (rocket Family)
Titan was a family of United States expendable rockets used between 1959 and 2005. The Titan I and Titan II were part of the US Air Force's intercontinental ballistic missile (ICBM) fleet until 1987. The space launch vehicle versions contributed the majority of the 368 Titan launches, including all the Project Gemini crewed flights of the mid-1960s. Titan vehicles were also used to lift US military payloads as well as civilian agency reconnaissance satellites and to send interplanetary scientific probes throughout the Solar System. Titan I missile The HGM-25A Titan I, built by the Martin Company, was the first version of the Titan family of rockets. It began as a backup ICBM project in case the SM-65 Atlas was delayed. It was a two-stage rocket operational from early 1962 to mid-1965 whose LR-87 booster engine was powered by RP-1 (kerosene) and liquid oxygen (LOX). The ground guidance for the Titan was the UNIVAC ATHENA computer, designed by Seymour Cray, based in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Aerobee Rocket
The Aerobee rocket was one of the United States' most produced and productive sounding rockets. Developed by the Aerojet Corporation, the Aerobee was designed to combine the altitude and launching capability of the V-2 with the cost effectiveness and mass production of the WAC Corporal. More than 1000 Aerobees were launched between 1947 and 1985, returning vast amounts of astronomical, physical, aeronomical, and biomedical data. Development Research using V-2 rockets after World War II produced valuable results concerning the nature of cosmic rays, the solar spectrum, and the distribution of atmospheric ozone. However, the limited supply and the expense of assembling and firing the V-2 rockets, as well as the small payload capacity of the first purpose-built sounding rocket, the WAC Corporal, created demand for a low cost sounding rocket to be used for scientific research. An Applied Physics Laboratory (APL) effort led by James Van Allen led to a contract presented 17 May 1946 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JATO
JATO (acronym for jet-assisted take-off) is a type of assisted take-off for helping overloaded aircraft into the air by providing additional thrust in the form of small rockets. The term ''JATO'' is used interchangeably with the (more specific) term RATO, for ''rocket-assisted take-off'' (or, in Royal Air Force, RAF parlance, RATOG, for ''rocket-assisted take-off gear''). Early experiments and World War II In 1927 the Soviet research and development laboratory Gas Dynamics Laboratory developed solid-propellant rockets to assist aircraft take-off and in 1931 the world's first successful use of rockets to assist take-off of aircraft were carried out on a :ru:У-1, U-1, the Soviet Union military aircraft designation systems, Soviet designation for a Avro 504 trainer, which achieved about one hundred successful assisted takeoffs. Successful assisted takeoffs were also achieved on the Tupolev TB-1. and Tupolev TB-3 Heavy Bombers. The official test of the Tupolev TB-1 in 1933 shorten ...
