Scout (rocket Family)
The Scout family of rockets were American launch vehicles designed to place small satellites into orbit around the Earth. The Scout multistage rocket was the first orbital launch vehicle to be entirely composed of solid fuel stages. It was also the only vehicle of that type until the successful launch of the Japanese Lambda 4S in 1970. The original Scout (a backronym for Solid Controlled Orbital Utility Test system) was designed in 1957 at the NACA, at Langley center. Scout launch vehicles were used from 1961 until 1994. To enhance reliability the development team opted to use "off the shelf" hardware, originally produced for military programs. According to the NASA The National Aeronautics and Space Administration (NASA ) is an independent agencies of the United States government, independent agency of the federal government of the United States, US federal government responsible for the United States ... fact sheet: "... the first stage motor was a combination of the ...

Altair (rocket Stage)
The Altair was a solid-fuel rocket with a fiberglass casing, initially developed for use as the multistage rocket, third stage of Vanguard rockets in 1959. It was manufactured by Allegany Ballistics Laboratory (ABL) as the X-248. It was also sometimes called the Burner (rocket stage), Burner 1. Altair The X-248 was one of two third-stage designs used during Project Vanguard. Early launches used a stage developed by the Lockheed Propulsion Company, Grand Central Rocket Company, but the last used the X-248 which enabled the Vanguard to launch more massive payload. The X-248 was used as the second stage of some early Thor (rocket family), Thor flights. These vehicles were designated "Thor-Burner". Altairs were used as the third stage of early Delta rockets. The fourth stage of the Scout X-1, Scout-X rocket used the "Altair-1A" stage, powered by a X-248A engine. Altair 2 The Altair 2 (X-258) Thiokol (Star (rocket stage), Star 25, TE-M-184-3) solid rocket engine first flew in 196 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

LGM-30 Minuteman
The LGM-30 Minuteman is an American land-based intercontinental ballistic missile (ICBM) in service with the Air Force Global Strike Command. , the LGM-30G (Version 3) is the only land-based ICBM in service in the United States and represents the land leg of the U.S. nuclear triad, along with the Trident II submarine-launched ballistic missile (SLBM) and nuclear weapons carried by long-range strategic bombers. Development of the Minuteman began in the mid-1950s when basic research indicated that a solid-fuel rocket motor could stand ready to launch for long periods of time, in contrast to liquid-fueled rockets that required fueling before launch and so might be destroyed in a surprise attack. The missile was named for the colonial minutemen of the American Revolutionary War, who could be ready to fight on short notice. The Minuteman entered service in 1962 as a deterrence weapon that could hit Soviet cities with a second strike and countervalue counterattack if the U.S. wa ...

Thiokol
Thiokol was an American corporation concerned initially with rubber and related chemicals, and later with rocket and missile propulsion systems. Its name is a portmanteau of the Greek words for sulfur () and glue (), an allusion to the company's initial product, Thiokol polymer. The Thiokol Chemical Company was founded in 1929. Its initial business was a range of synthetic rubber and polymer sealants. Thiokol was a major supplier of liquid polymer sealants during World War II. When scientists at the Jet Propulsion Laboratory discovered that Thiokol's polymers made ideal binders for solid rocket fuels, Thiokol moved into the new field, opening laboratories at Elkton, Maryland, and later production facilities at Elkton and at Redstone Arsenal in Huntsville, Alabama. Huntsville produced the XM33 Pollux, TX-18 Falcon, and TX-135 Nike-Zeus systems. It closed in 1996. In the mid-1950s the company bought extensive lands in Utah for its rocket test range. Thiokol was involved in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerojet General

Sergeant (missile)
The MGM-29 Sergeant was an American short-range, solid fuel, surface-to-surface missile developed by the Jet Propulsion Laboratory. The missiles were built by Sperry Utah Company. The Sergeant was the third and last in a series of JPL rockets for the US Army whose names correspond to the progression in Army enlisted ranks, starting with Private and Corporal. The Sergeant missile was first fired by an operational field artillery unit at White Sands New Mexico by the 3rd Battalion 38th Artillery station at Fort Sill Oklahoma in the summer of 1962. President John F. Kennedy attended the fire power demonstration at White Sands New Mexico. Development The Sergeant was originated during 1948 at JPL. Due to the large workload of the Corporal program rocket motor development for the Sergeant was transferred to the Redstone Division of the Thiokol Corporation. Due to the failure of the Sergeant program to develop rapidly the early Sergeant was terminated in April 1951.Cagle, Mary T., Hist ...

Kilogram-force
The kilogram-force (kgf or kgF), or kilopond (kp, from ), is a non-standard Gravitational metric system, gravitational metric unit of force. It is not accepted for use with the International System of Units (SI) and is deprecated for most uses. The kilogram-force is equal to the magnitude of the force exerted on one kilogram of mass in a gravitational field (standard gravity, a conventional value approximating the average magnitude of gravity on Earth). That is, it is the weight of a kilogram under standard gravity. One kilogram-force is defined as .NIST]''Guide for the Use of the International System of Units (SI)''Special Publication 811, (1995) page 51 Similarly, a gram-force is , and a milligram-force is . History The gram-force and kilogram-force were never well-defined units until the CGPM adopted a ''standard acceleration of gravity'' of 9.80665 m/s2 for this purpose in 1901, though they had been used in low-precision measurements of force before that time.

Kilonewton
The newton (symbol: N) is the unit of force in the International System of Units (SI). Expressed in terms of SI base units, it is 1 kg⋅m/s2, the force that accelerates a mass of one kilogram at one metre per second squared. The unit is named after Isaac Newton in recognition of his work on classical mechanics, specifically his second law of motion. Definition A newton is defined as 1 kg⋅m/s2 (it is a named derived unit defined in terms of the SI base units). One newton is, therefore, the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in the direction of the applied force. The units "metre per second squared" can be understood as measuring a rate of change in velocity per unit of time, i.e. an increase in velocity by one metre per second every second. In 1946, the General Conference on Weights and Measures (CGPM) Resolution 2 standardized the unit of force in the MKS system of units to be the amount needed t ...
