With the Atar 101 now sitting at the low end of the power scale, in 1954 SNECMA started the design of a more radical upgrade, the Atar 08. Overall design and dimensions were similar to the 101, but the new engine included a nine-stage compressor in place of the earlier seven-stage one, and a smaller two-stage turbine to power it.
The engine was derived from the Atar series by adding a bypass duct aft of the 3rd compressor stage. The first 3 stages were enlarged to give an LP and HP section on the same shaft. It is a single shaft turbofan, or continuous bleed/bypass turbojet. [1] It was originally called the Super Atar 9K50 and was designed for sustained flight at Mach 2 ...
Physics – branch of science that studies matter [9] and its motion through space and time, along with related concepts such as energy and force. [10] Physics is one of the "fundamental sciences" because the other natural sciences (like biology, geology etc.) deal with systems that seem to obey the laws of physics. According to physics, the ...
[10] [11] Moreover, words which are synonymous in everyday speech are not so in physics: force is not the same as power or pressure, for example, and mass has a different meaning than weight. [12] [13]: 150 The physics concept of force makes quantitative the everyday idea of a push or a pull. Forces in Newtonian mechanics are often due to ...
The Feynman Lectures on Physics is a physics textbook based on a great number of lectures by Richard Feynman, a Nobel laureate who has sometimes been called "The Great Explainer". [1] The lectures were presented before undergraduate students at the California Institute of Technology (Caltech), during 1961–1964.
Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions, in addition to the study of other forms of nuclear matter. Nuclear physics should not be confused with atomic physics , which studies the atom as a whole, including its electrons .
ARTE France will launch 30 Birds, an upcoming puzzle video game inspired by Persian art and The Conference of the Birds. [9] Set in the magical city of The Lanterns, the player takes on the role of Zig, a female detective assigned to track down an internationally wanted criminal known as "The Scientist", who is also the prime suspect in the ...
Mohamed Atta [a] (1 September 1968 – 11 September 2001) was an Egyptian terrorist hijacker for al-Qaeda.Ideologically a pan-Islamist, he was the ringleader of the September 11 attacks and served as the hijacker-pilot of American Airlines Flight 11, which he crashed into the North Tower of the original World Trade Center as part of the coordinated suicide attacks.
