RS-84 Artists Concept
The Space Launch Initiative (SLI) was a NASA and U.S. Department of Defense joint research and technology project to determine the requirements to meet all the nation's hypersonics, space launch and space technology needs. It was also known as the second generation Reusable Launch Vehicle program, after the failure of the first. The program began with the award of RLV study contracts in 2000. The primary goal of the research was to increase safety and reliability and to reduce overall costs associated with building, flying and maintaining the nation's next generation of space launch vehicles. NASA anticipated that these advances would revitalize the nation's space transportation capabilities, and dramatically improve NASA's ability to conduct science and exploration missions in space. This program was evolved into the Orbital Space Plane Program and the Next Generation Launch Technology program in November 2002. In 2004 NASA moved on to the Constellation Program, part of the Vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rocketplane Kistler
Rocketplane Kistler (RpK) was a reusable launch system firm originally based in Oklahoma. It was formed in 2006 after Rocketplane Limited, Inc. acquired Kistler Aerospace. NASA announced that Rocketplane Kistler had been chosen to develop crew and cargo launch services. However, having missed financial milestones NASA terminated funding for the project. It filed for chapter 7 bankruptcy in 2010. K-1 launch vehicle Rocketplane Kistler's primary project was the K-1, a reusable launch vehicle which was intended to get as high as geosynchronous orbit, and was hoped to compete with relatively expensive, one-shot rockets for servicing of the International Space Station. Corporate history Kistler Aerospace was founded in Kirkland, Washington by Walter Kistler and Bob Citron in 1993 as a private company attempting to develop fully reusable vehicles capable of earth orbit at a minimal price.

Reusable Booster System
The Reusable Booster System (RBS) was a United States Air Force research program, circa 2010 to 2012, to develop a new prototype vertical-takeoff, horizontal-landing (VTHL) reusable booster and a new prototype expendable second stage to replace the existing Evolved Expendable Launch Vehicles (EELV) after 2025. The program was discontinued in 2012. History Program funding was initially set at ."Officials anticipate awarding up to three contracts for the project, where winners would compete for individual tasks of experiments and demonstrations that address technology, processes and other attributes of a reusable booster system, or RBS." The proposal deadline was March 19, 2011. The Air Force had developed a notional plan to build a fleet of eight of the RBS systems, to be flown from both Vandenberg Air Force Base in California and Cape Canaveral Air Force Station in Florida. Three designs were submitted: by Andrews Space, Boeing and Lockheed Martin. The first phase of the flight ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

TR-107
The TR-107 was a developmental rocket engine designed in 2002 by Northrop Grumman for NASA and DoD funded Space Launch Initiative. Operating on LOX/RP-1 the engine was throttleable and had a thrust of at a chamber pressure of , making it one of the most powerful engines ever constructed. History The TR-107 was built by TRW following the successful conclusion of the development program for the TR-106 engine, a similar throttleable engine of about half the thrust burning LOX/ LH2 instead of LOX / RP-1. Tom Mueller, then VP of Propulsion Development at Northrop, was project manager for both the TR-106 and TR-107 engines. In 2002, Mueller co-founded SpaceX with Elon Musk and became the VP of propulsion after cancellation of SLI program.

TR-106
The TR-106 or low-cost pintle engine (LCPE) was a developmental rocket engine designed by TRW Inc., TRW under the Space Launch Initiative to reduce the cost of Launch service provider, launch services and space flight. Operating on LOX/LH2 the engine had a thrust of 2892 kN, or 650,000 pounds, making it one of the most powerful engines ever constructed. Overview The goal of the development was to produce a large, low-cost, easy-to-manufacture booster engine. The design used a single element coaxial pintle injector, a robust type of injector. It also used ablative cooling of the combustion chamber and nozzle instead of the more costly to manufacture regenerative cooling. The use of the pintle injector allows the engine thrust to be widely Throttleable rocket engine, throttleable, as was the case for the lunar module descent engine. Status Tom Mueller was a lead engineer for development of the LCPE, a 650,000 lbf thrust LOX/LH2 engine. In the summer of 2000, this LCPE wa ...

Energia (rocket)
Energia (russian: Энергия, Energiya, Energy; GRAU 11K25) was a 1980s super-heavy lift launch vehicle. It was designed by NPO Energia of the Soviet Union as part of the Buran programme, Buran program for a variety of payloads including the Buran (spacecraft), Buran spacecraft. Control system main developer enterprise was the Khartron NPO "Electropribor". The Energia used four strap-on boosters each powered by a four-chamber RD-170 engine burning kerosene/Liquid oxygen, LOX, and a central core stage with four single-chamber RD-0120 (11D122) engines fueled by liquid hydrogen/LOX. The launch vehicle had two functionally different operational variants: Energia-Polyus, the initial test configuration, in which the Polyus (spacecraft), Polyus system was used as a final stage intended to put the payload into orbit, and Energia-Buran, in which the Buran programme, ''Buran'' orbiter was the payload and the source of the orbit insertion impulse.

RD-170
The RD-170 ( rus, РД-170, Ракетный Двигатель-170, Raketnyy Dvigatel-170) is the world's most powerful and heaviest liquid-fuel rocket engine. It was designed and produced in the Soviet Union by NPO Energomash for use with the Energia launch vehicle. The engine burns kerosene fuel and LOX oxidizer in four combustion chambers, all supplied by one single-shaft, single-turbine turbopump rated at in a staged combustion cycle. Shared turbopump Several Soviet and Russian rocket engines use the approach of clustering small combustion chambers around a single turbine and pump. During the early 1950s, many Soviet engine designers, including Valentin P. Glushko, faced problems of combustion instability while designing bigger thrust chambers. At that time, they solved the problem by using a cluster of smaller thrust chambers. Variants RD-170 The RD-170 engine featured four combustion chambers and was developed for use on the Energia launch vehicle – both the eng ...

Liquid Rocket
A liquid-propellant rocket or liquid rocket utilizes a rocket engine that uses liquid propellants. Liquids are desirable because they have a reasonably high density and high specific impulse (''I''sp). This allows the volume of the propellant tanks to be relatively low. It is also possible to use lightweight centrifugal turbopumps to pump the rocket propellant from the tanks into the combustion chamber, which means that the propellants can be kept under low pressure. This permits the use of low-mass propellant tanks that do not need to resist the high pressures needed to store significant amounts of gasses, resulting in a low mass ratio for the rocket. An inert gas stored in a tank at a high pressure is sometimes used instead of pumps in simpler small engines to force the propellants into the combustion chamber. These engines may have a higher mass ratio, but are usually more reliable, and are therefore used widely in satellites for orbit maintenance. Liquid rockets can be monop ...
