IAR 111
The IAR-111 Excelsior is a supersonic mothership project, designed by ARCA Space Corporation, intended to transport a rocket payload up to and for developing space tourism related technologies. The aircraft is to be constructed almost entirely from composite materials, and will be designed for take-off and landing from the sea surface. History The design of the aircraft started before the successful launch of the Helen 2 rocket. ARCA kept work on the project secret and decided to reveal it to the public in a press conference that took place at BRD headquarters in Bucharest in December 2010. The initial name of the aircraft was E-111. In March 2011 ARCA received approval from IAR S.A. Brasov to use its initials on the aircraft, so E-111 was officially renamed IAR-111. Work on the fuselage moulds started in early 2011 and were completed in September. The cockpit structure was completed in July. It is detachable from the rest of the aircraft and will be equipped with two rocket p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haas (rocket)
Haas is a family of rocket space launchers developed by ARCAspace for the Google Lunar X Prize competition and for their national crewed space program. no rocket has been launched, the planned rocket types changed significantly over time. It was named after Conrad Haas, a medieval rocket pioneer who lived and worked in what is now Romania, and was the first person to describe a multistage rocket in writing. Haas Haas was a Romanian carrier rocket, which was developed by ARCASPACE, ARCA as part of the European Lunar Explorer, ELE programme. It was designed to be air-launched from a high-altitude balloon, similar to the United States, American Rockoon experiments of the 1950s. Prior to the development of Haas, ARCA had already launched two Stabilo (rocket), Stabilo rockets from balloons. It is fueled by hydrogen peroxide and bitumen. The Haas rocketARCA SpaceHaas Orbital Rocket Launcher fact sheet, Dec. 2, 2008 (accessed 22 Sept 2014) was to be a three-stage rocket intended to ...

Liquid Oxygen
Liquid oxygen—abbreviated LOx, LOX or Lox in the aerospace, submarine and gas industries—is the liquid form of molecular oxygen. It was used as the oxidizer in the first liquid-fueled rocket invented in 1926 by Robert H. Goddard, an application which has continued to the present. Physical properties Liquid oxygen has a pale blue color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. Liquid oxygen has a density of , slightly denser than liquid water, and is cryogenic with a freezing point of and a boiling point of at . Liquid oxygen has an expansion ratio of 1:861 under and , and because of this, it is used in some commercial and military aircraft as a transportable source of breathing oxygen. Because of its cryogenic nature, liquid oxygen can cause the materials it touches to become extremely brittle. Liquid oxygen is also a very powerful oxidizing agent: organic materials will burn rapidly and energetically in liquid o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Experimental Aircraft
An experimental aircraft is an aircraft intended for testing new aerospace technologies and design concepts. The term ''research aircraft'' or ''testbed aircraft'', by contrast, generally denotes aircraft modified to perform scientific studies, such as weather research or geophysical surveying, similar to a research vessel. United States The term "experimental aircraft" also has specific legal meaning in Australia, the United States and some other countries; usually used to refer to aircraft flown with an experimental certificate. In the United States, this also includes most homebuilt aircraft, many of which are based on conventional designs and hence are experimental only in name because of certain restrictions in operation.

Private Spaceflight
Private spaceflight is spaceflight or the development of spaceflight technology that is conducted and paid for by an entity other than a government agency. In the early decades of the Space Age, the government space agencies of the Soviet Union and United States pioneered space technology in collaboration with affiliated design bureaus in the USSR and private companies in the US, entirely funding both the development of new spaceflight technologies and the operational costs of spaceflight. The European Space Agency was formed in 1975, largely following the same model of space technology development. However, Arianespace became the world's first commercial launch service provider in the early 1980s. Later on, large defense contractors began to develop and operate space launch systems, derived from government rockets. Private spaceflight in Earth orbit includes communications satellites, satellite television, satellite radio, astronaut transport and sub-orbital and orbital spa ...

SpaceShipOne
SpaceShipOne is an experimental air-launched rocket-powered aircraft with sub-orbital spaceflight capability at speeds of up to 3,000 ft/s (900 m/s, 3240 km/h), using a hybrid rocket motor. The design features a unique "feathering" atmospheric reentry system where the rear half of the wing and the twin tail booms folds 70 degrees upward along a hinge running the length of the wing; this increases drag while retaining stability. SpaceShipOne completed the first crewed private spaceflight in 2004. That same year, it won the US$10 million Ansari X Prize and was immediately retired from active service. Its mother ship was named " White Knight". Both craft were developed and flown by Mojave Aerospace Ventures, which was a joint venture between Paul Allen and Scaled Composites, Burt Rutan's aviation company. Allen provided the funding of approximately US$25 million. Rutan has indicated that ideas about the project began as early as 1994 and the full-time development cycl ...

Shuttle Carrier Aircraft
The Shuttle Carrier Aircraft (SCA) are two extensively modified Boeing 747 airliners that NASA used to transport Space Shuttle orbiters. One (N905NA) is a 747-100 model, while the other (N911NA) is a short range 747-100SR. The SCAs were used to ferry Space Shuttles from landing sites back to the Shuttle Landing Facility at the Kennedy Space Center. The orbiters were placed on top of the SCAs by Mate-Demate Devices, large gantry-like structures that hoisted the orbiters off the ground for post-flight servicing then mated them with the SCAs for ferry flights. In approach and landing test flights conducted in 1977, the test shuttle ''Enterprise'' was released from an SCA during flight and glided to a landing under its own control. Design and development The Lockheed C-5 Galaxy was considered for the shuttle-carrier role by NASA, but rejected in favor of the 747. This was due to the 747's low-wing design in comparison to the C-5's high-wing design, and also because the U.S. Ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pegasus (rocket)
Pegasus is an air-launched launch vehicle developed by Orbital Sciences Corporation (OSC) and now built and launched by Northrop Grumman. Capable of carrying small payloads of up to into low Earth orbit, Pegasus first flew in 1990 and remains active . The vehicle consists of three solid propellant stages and an optional monopropellant fourth stage. Pegasus is released from its carrier aircraft at approximately , and its first stage has a wing and a tail to provide lift and attitude control while in the atmosphere. Notably, the first stage does not have a thrust vector control (TVC) system. History Pegasus was designed by a team led by Antonio Elias. The Pegasus's three Orion solid motors were developed by Hercules Aerospace (later Alliant Techsystems) specifically for the Pegasus launcher but using advanced carbon fiber, propellant formulation and case insulation technologies originally developed for the terminated USAF Small ICBM program. The wing and fins' structures w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North American X-15
The North American X-15 is a hypersonic rocket-powered aircraft. It was operated by the United States Air Force and the National Aeronautics and Space Administration as part of the X-plane series of experimental aircraft. The X-15 set speed and altitude records in the 1960s, reaching the edge of outer space and returning with valuable data used in aircraft and spacecraft design. The X-15's highest speed, , was achieved on 3October 1967, when William J. Knight flew at Mach6.7 at an altitude of , or 19.34miles. This set the official world record for the highest speed ever recorded by a crewed, powered aircraft, which remains unbroken. During the X-15 program, 12pilots flew a combined 199flights. Of these, 8pilots flew a combined 13flights which met the Air Force spaceflight criterion by exceeding the altitude of , thus qualifying these pilots as being astronauts; of those 13flights, two (flown by the same civilian pilot) met the FAI definition () of outer space.

Northrop YF-23
The Northrop/McDonnell Douglas YF-23 is an American single-seat, twin-engine stealth fighter aircraft technology demonstrator designed for the United States Air Force (USAF). The design was a finalist in the USAF's Advanced Tactical Fighter (ATF) competition, battling the Lockheed YF-22 for a production contract. Two YF-23 prototypes were built, nicknamed "Black Widow II" and "Gray Ghost". In the 1980s, the USAF began looking for a replacement for its fighter aircraft, especially to counter the USSR's advanced Sukhoi Su-27 and Mikoyan MiG-29. Several companies submitted design proposals; the USAF selected proposals from Northrop and Lockheed. Northrop teamed with McDonnell Douglas to develop the YF-23, while Lockheed, Boeing, and General Dynamics developed the YF-22. The YF-23 was stealthier and faster, but less agile than its competitor. After a four-year development and evaluation process, the YF-22 was announced the winner in 1991 and entered production as the Lockheed M ...

Stall (flight)
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 486. Aviation Supplies & Academics, 1997. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil, and Reynolds number. Stalls in fixed-wing flight are often experienced as a sudden reduction in lift as the pilot increases the wing's angle of attack and exceeds its critical angle of attack (which may be due to slowing down below stall speed in level flight). A stall does not mean that the engine(s) have stopped working, or that the aircraft has stopped moving—the effect is the same even in an unpowered glider aircraft. Vectored thrust in aircraft is used to maintain altitude or controlled flight with wings stalled by replacing lost wing lift with engine or propeller t ...

Kerosene
Kerosene, paraffin, or lamp oil is a combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in aviation as well as households. Its name derives from el, κηρός (''keros'') meaning "wax", and was registered as a trademark by Canadian geologist and inventor Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage. The term kerosene is common in much of Argentina, Australia, Canada, India, New Zealand, Nigeria, and the United States, while the term paraffin (or a closely related variant) is used in Chile, eastern Africa, South Africa, Norway, and in the United Kingdom. The term lamp oil, or the equivalent in the local languages, is common in the majority of Asia and the Southeastern United States. Liquid paraffin (called mineral oil in the US) is a more viscous and highly refined product which is used as a laxative. Paraffin wax is a waxy solid extracted from pet ...
