Rolls-Royce RZ.2
The RZ.2 was a British design for a liquid oxygen (LOX) / kerosene-fuelled rocket engine to power the Blue Streak (missile). The design was a development of the Rolls-Royce RZ.1 rocket engine, which had in turn been a development by Rolls-Royce of the Rocketdyne S-3D. Rolls-Royce, Ansty was the design authority. Two variants of this engine were developed: the first provided a static thrust of and the second (intended for the three stage satellite launch vehicle) . The engines could be vectored by seven degrees in flight for guidance. Some disconnected facts for arrangement: The Efflux chamber of the engine was made of nickel tubes brazed together through which flowed kerosene down one tube and back up the adjacent tube via a manifold at the mouth of the chamber. After static firings, these chambers were checked by climbing inside the engine from beneath. The mouth was in diameter but that of the throat was smaller, which restricted access to the inspector. In addition, du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles.

The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people. The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years.

National Space Centre
The National Space Centre is a museum and educational resource covering the fields of space science and astronomy, along with a space research programme in partnership with the University of Leicester. It is located on the north side of the city in Belgrave, Leicester, England, next to the River Soar. Many of the exhibits, including upright rockets, are housed in a tower with minimal steel supports and a semi-transparent cladding of ETFE 'pillows' which has become one of Leicester's most recognisable landmarks. The National Space Centre is a registered charity with a board of trustees. History The initial idea of a space centre as a research facility but with public access, attached to the University of Leicester, was first conceived in the 1980s – the idea of Professor Alan Wells and Professor Ken Pounds of the university. The plan was not taken further due to lack of funds. The Space Centre as a museum was then put forward in 1995 – by Professor Alan Wells and Alan Ponter, ...

Rocket Engines Of The United Kingdom
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. Signif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The city of Cambridge is the county town. Following the Local Government Act 1972 restructuring, modern Cambridgeshire was formed in 1974 through the amalgamation of two administrative counties: Cambridgeshire and Isle of Ely, comprising the Historic counties of England, historic county of Cambridgeshire (including the Isle of Ely); and Huntingdon and Peterborough, comprising the historic county of Huntingdonshire and the Soke of Peterborough, historically part of Northamptonshire. Cambridgeshire contains most of the region known as Silicon Fen. The county is now divided between Cambridgeshire County Council and Peterborough City Council, which since 1998 has formed a separate Unitary authorities of England, unita ...

Redu
Redu ( wa, Ridû) is a village of Wallonia and district of the municipality of Libin, located in the province of Luxembourg, Belgium. The village is twinned with Hay-on-Wye in the United Kingdom and was one of the first book towns. The village was given new life by the development of the book trade in the 1980s but now faces an uncertain future with the decline in the brick-and-mortar book trade. Several of the book shops have closed and most of the others are having trouble. The ESTRACK Redu Station for the European Space Agency is located about a kilometre away.

Armagh Planetarium
Armagh Planetarium is a planetarium located in Armagh, Northern Ireland close to the city centre and neighbouring Armagh Observatory in approximately fourteen acres of landscaped grounds known as the Armagh Astropark. History Armagh Planetarium was established by the seventh director of Armagh Observatory, Dr. Eric Mervyn Lindsay, who, after twenty-five years of effort, secured funding from local councils and the Ministry of Commerce of Northern Ireland in 1965. In the same year Patrick Moore was appointed as Director of the Planetarium to oversee its construction. The planetarium cost £120,000 to build (included in this was £12,000 for the planetarium’s first projector) and was officially opened on 1 May 1968, although it had been open to the public for some months before that. Since then it has undergone many alterations: the main building was extended in 1974 to incorporate the Lindsay Hall of Astronomy, and a dome was created to house a 16" (400 mm) reflecting te ...

Hydraulic Fluid
A hydraulic fluid or hydraulic liquid is the medium by which power is transferred in hydraulic machinery. Common hydraulic fluids are based on mineral oil or water. Examples of equipment that might use hydraulic fluids are excavators and backhoes, hydraulic brakes, power steering systems, automatic transmissions, garbage trucks, aircraft flight control systems, lifts, and industrial machinery. Hydraulic systems like the ones mentioned above will work most efficiently if the hydraulic fluid used has zero compressibility. Functions and properties The primary function of a hydraulic fluid is to convey power. In use, however, there are other important functions of hydraulic fluid such as protection of the hydraulic machine components. The table below lists the major functions of a hydraulic fluid and the properties of a fluid that affect its ability to perform that function: Composition Base stock The original hydraulics fluid, dating back to the time of ancient Egypt ...

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] |
