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] |
United States Air Force
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control.

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. Status Northrop Grumman development of the ''TR-107'' engine permitted consideration for potential use on next-generation launch and space transportation system.

Aviation Week
''Aviation Week & Space Technology'', often abbreviated ''Aviation Week'' or ''AW&ST'', is the flagship magazine of the Aviation Week Network. The weekly magazine is available in print and online, reporting on the aerospace, defense and aviation industries, with a core focus on aerospace technology. It has a reputation for its contacts inside the United States military and industry organizations. ''Aviation Week'' was a favorite conduit for defense-related companies and labs to leak information to the public as part of their policy by press release efforts. This led to it being informally referred to "Aviation Leak and Space Mythology". History The magazine was first published in August 1916. Early editors Ladislas d'Orsy and Donald W. McIlhiney (1921 to 25) were Quiet Birdmen. Publisher (1927 to 29) Earl D. Osborn was also a Quiet Birdman. With the coming of the Space Age, the current title was adopted in 1960.

XS-1 (spacecraft)
The DARPA XS-1 was an experimental spaceplane/booster with the planned capability to deliver small satellites into orbit for the U.S. Military. It was reported to be designed to be reusable as frequently as once a day, with a stated goal of doing so for 10 days straight. The XS-1 was intended to directly replace the first stage of a multistage rocket by taking off vertically and flying to hypersonic speed and high suborbital altitude, enabling one or more expendable upper stages to separate and deploy a payload into low Earth orbit. The XS-1 would then return to Earth, where it could ostensibly be serviced fast enough to repeat the process at least once every 24 hours. The DARPA XS-1 program operated 2013–2020. After several years of refinement and proposals, in May 2017, the Defense Advanced Research Projects Agency (DARPA) selected Boeing for Phase 2/3 to build and test an XS-1 spacecraft (now called the Experimental Spaceplane program). At the time, test flights were schedul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Visi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocket-based Combined Cycle
The RBCC, or rocket-based combined cycle propulsion system, was one of the two types of propulsion systems that may have been tested in the Boeing X-43 experimental aircraft. The RBCC, or strutjet as it is sometimes called, is a combination propulsion system that consists of a ramjet, scramjet, and ducted rocket, where all three systems use a shared flow path. A TBCC, or turbine-based combined cycle propulsion system, is a turbine engine combined with a ramjet and scramjet. A TRCC, or turbo rocket combined cycle propulsion system, is another combination propulsion system that combines an afterburning turbine engine with a RBCC propulsion system.

Reusable Launch System
A reusable launch vehicle have parts that can be recovered and reflown, while carrying payloads from the surface to outer space. Rocket stages are the most common launch vehicle parts aimed for reuse. Smaller parts such as rocket engines and boosters can also be reused, though reusable spacecraft may be launched on top of an expendable launch vehicle. Reusable launch vehicles do not need to make these parts for each launch, therefore reducing its launch cost significantly. However, these benefits are diminished by the cost of recovery and refurbishment. Reusable launch vehicles may contain additional avionics and propellant, making them heavier than their expendable counterparts. Reused parts may need to enter the atmosphere and navigate through it, so they are often equipped with heat shields, grid fins, and other flight control surfaces. By modifying their shape, spaceplanes can leverage aviation mechanics to aid in its recovery, such as gliding or lift. In the atmosphere, par ...

Liquid Fly-back Booster
Liquid Fly-back Booster (LFBB) was a German Aerospace Center's (DLR's) project concept to develop a liquid rocket booster capable of reusing for Ariane 5 in order to significantly reduce the high cost of space transportation and increase environmental friendliness. LFBB would replace the existing solid rocket boosters, providing main thrust during the liftoff. Once separated, two winged boosters would perform an atmospheric entry, fly back autonomously to the French Guiana, and land horizontally on the airport like an aeroplane. Additionally a family of derivative launch vehicles was proposed in order to take an advantage of economies of scale, further reducing launch costs. These derivatives include: * A reusable booster in a class of small and medium-lift launch vehicles like Vega and Arianespace Soyuz. * A super-heavy-lift launch vehicle capable of lifting nearly to the orbit. * A two-stage-to-orbit system operating a dedicated reusable orbiter.

Baikal (rocket Booster)
The Baikal booster (russian: Байкал) was a proposed reusable flyback booster for the Angara rocket family based on the Angara Universal Rocket Module in 2001. It was designed by the Molniya Research and Industrial Corporation (NPO Molniya) for the Khrunichev Space centre, reusing the flyback and control system for the reusable Buran orbiter. Description The booster would be equipped with an RD-191 rocket engine burning kerosene and liquid oxygen to provide approximately 200 tons of thrust. In addition, it would be equipped with a folding wing stored parallel to the fuselage of the vehicle during the booster stage of the flight. After separation from the Angara launcher's second stage at an altitude of about 75 kilometers and a speed of , the Baikal's wing would rotate 90 degrees and the booster glides in upside down position reducing speed. Once the booster reaches subsonic speeds, a U-turn is performed and an air-breathing RD-33 jet engine in its nose section is star ...

RL60
The RL60 was a planned liquid-fuel cryogenic rocket engine designed in the United States by Pratt & Whitney, burning cryogenic liquid hydrogen and liquid oxygen propellants. The engine runs on an expander cycle, running the turbopumps with waste heat absorbed from the main combustion process. This high-efficiency, waste heat based combustion cycle combined with the high-performance liquid hydrogen fuel enables the engine to reach a very high specific impulse of up to 465 seconds in a vacuum. The engine was planned to be a more capable successor to the Aerojet Rocketdyne RL10, providing improved performance and efficiency while maintaining the installation envelope of the RL10. RL60 was planned to include major improvements to the high-thrust RL10B-2, such as up to 45 engine restarts (up from 15 for RL10B-2), 550 seconds longer engine lifetime (+15.7%), and twice the thrust. Like the RL10B-2, RL60 was planned to incorporate a radiatively cooled extendable nozzle. RL60 was desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
