Space Launch Initiative
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 Vis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TR-106
The TR-106 or low-cost pintle engine (LCPE) was a developmental rocket engine designed by TRW under the Space Launch Initiative to reduce the cost of 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, 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 was successfully hot fire tested at 100 percent of its rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

RP-1
RP-1 (alternatively, Rocket Propellant-1 or Refined Petroleum-1) is a highly refined form of kerosene outwardly similar to jet fuel, used as rocket fuel. RP-1 provides a lower specific impulse than liquid hydrogen (LH2), but is cheaper, is stable at room temperature, and presents a lower explosion hazard. RP-1 is far denser than LH2, giving it a higher energy density (though its specific energy is lower). RP-1 also has a fraction of the toxicity and carcinogenic hazards of hydrazine, another room-temperature liquid fuel. Usage and history RP-1 is a fuel in the first-stage boosters of the Electron, Soyuz, Zenit, Delta I-III, Atlas, Falcon, Antares, and Tronador II rockets. It also powered the first stages of the Energia, Titan I, Saturn I and IB, and Saturn V. The Indian Space Research Organization (ISRO) is also developing an RP-1 fueled engine for its future rockets.

Throttleable Rocket Engine
A rocket engine uses stored rocket propellants as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas. Rocket engines are reaction engines, producing thrust by ejecting mass rearward, in accordance with Newton's third law. Most rocket engines use the combustion of reactive chemicals to supply the necessary energy, but non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist. Vehicles propelled by rocket engines are commonly called rockets. Rocket vehicles carry their own oxidiser, unlike most combustion engines, so rocket engines can be used in a vacuum to propel spacecraft and ballistic missiles. Compared to other types of jet engine, rocket engines are the lightest and have the highest thrust, but are the least propellant-efficient (they have the lowest specific impulse). The ideal exhaust is hydrogen, the lightest of all elements, but chemical rockets produce a mix of heavier species, red ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Merlin (rocket Engine Family)
Merlin ( cy, Myrddin, kw, Marzhin, br, Merzhin) is a mythical figure prominently featured in the legend of King Arthur and best known as a mage, with several other main roles. His usual depiction, based on an amalgamation of historic and legendary figures, was introduced by the 12th-century British author Geoffrey of Monmouth. It is believed that Geoffrey combined earlier tales of Myrddin and Ambrosius, two legendary Briton prophets with no connection to Arthur, to form the composite figure called Merlinus Ambrosius ( cy, Myrddin Emrys, br, Merzhin Ambroaz). Geoffrey's rendering of the character became immediately popular, especially in Wales. Later writers in France and elsewhere expanded the account to produce a fuller image, creating one of the most important figures in the imagination and literature of the Middle Ages. Merlin's traditional biography casts him as an often-mad being born of a mortal woman, sired by an incubus, from whom he inherits his supernatural ...

Raptor (rocket Engine Family)
Raptor is a family of full-flow staged-combustion-cycle rocket engines developed and manufactured by SpaceX for use on the in-development SpaceX Starship. The engine is powered by cryogenic liquid methane and liquid oxygen ("methalox") rather than the RP-1 and liquid oxygen ("kerolox") used in SpaceX's prior Merlin and Kestrel rocket engines. The Raptor engine has more than twice the thrust of SpaceX's Merlin 1D engine that powers the Falcon 9 and Falcon Heavy launch vehicles. Raptor is used in the Starship system in both the super-heavy-lift Super Heavy booster and in the Starship spacecraft which acts as the second stage when launched from Earth and as an independent spacecraft in LEO and beyond. Starship is planned to be used in various applications, including Earth-orbit satellite delivery, deployment of a large portion of SpaceX's Starlink satellite constellation, exploration, Moon landing, and colonization of Mars.

Rocket Engines Using Kerosene Propellant
A rocket (from it, rocchetto, , bobbin/spool) is a vehicle that uses jet propulsion to accelerate without using the surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. Signi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
