Fulmar (rocket)
The Fulmar was a two-stage British sounding rocket. The Fulmar, developed by Bristol Aerojet Bristol Aerojet (BAJ) was a joint venture between the Bristol Aeroplane Company of the United Kingdom and Aerojet General of the US begun in 1959 using the existing factory at Banwell near Weston super Mare, England. History Banwell aircraft ..., consisted of a Heron starting stage with 107 kN thrust and a Snipe upper stage with 16.7 kN thrust. The Fulmar had a diameter of 26 centimetres and a length of 7.47 metres. It weighed 500 kilograms at launch and could reach a height of 250 kilometres. The Fulmar was fired six times between 1976 and 1979 at Andoya; the last launch, on 19 March 1979, failed.

Multistage Rocket
A multistage rocket or step rocket is a launch vehicle that uses two or more rocket ''stages'', each of which contains its own engines and propellant. A ''tandem'' or ''serial'' stage is mounted on top of another stage; a ''parallel'' stage is attached alongside another stage. The result is effectively two or more rockets stacked on top of or attached next to each other. Two-stage rockets are quite common, but rockets with as many as five separate stages have been successfully launched. By jettisoning stages when they run out of propellant, the mass of the remaining rocket is decreased. Each successive stage can also be optimized for its specific operating conditions, such as decreased atmospheric pressure at higher altitudes. This ''staging'' allows the thrust of the remaining stages to more easily accelerate the rocket to its final speed and height. In serial or tandem staging schemes, the first stage is at the bottom and is usually the largest, the second stage and subseq ...

Sounding Rocket
A sounding rocket or rocketsonde, sometimes called a research rocket or a suborbital rocket, is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight. The rockets are used to launch instruments from 48 to 145 km (30 to 90 miles) above the surface of the Earth, the altitude generally between weather balloons and satellites; the maximum altitude for balloons is about 40 km (25 miles) and the minimum for satellites is approximately 121 km (75 miles). Certain sounding rockets have an apogee between 1,000 and 1,500 km (620 and 930 miles), such as the Black Brant X and XII, which is the maximum apogee of their class. Sounding rockets often use military surplus rocket motors. NASA routinely flies the Terrier Mk 70 boosted Improved Orion, lifting 270–450-kg (600–1,000-pound) payloads into the exoatmospheric region between 97 and 201 km (60 and 125 miles).

Bristol Aerojet
Bristol Aerojet (BAJ) was a joint venture between the Bristol Aeroplane Company of the United Kingdom and Aerojet General of the US begun in 1959 using the existing factory at Banwell near Weston super Mare, England. History Banwell aircraft factory 1941-59 Built in 1941 under the authority of the Minister of Aircraft Production, the works was operated by the Bristol Aeroplane Company to build and repair Bristol Beaufort and Bristol Beaufighter torpedo fighter-bombers and Hawker Tempest fighters. After the war the company built pre-fab houses and schools there until the mid-fifties, and then rocket-motor manufacturing required by the Cold War took over. Bristol/Aerojet technical collaboration Discussions with Aerojet of California USA took place aimed at exploiting the varied rocket-making skills of the two companies, and in 1959 the Banwell works became Bristol Aerojet (BAJ), with a board chaired by Sir Reginald Verdon-Smith of Bristol Aeroplane Company, with Dan Kimball leadi ...

Experimental Rockets
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and informal natural comparisons (e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
