Ram Jet
A ramjet, or athodyd (aero thermodynamic duct), is a form of airbreathing jet engine that uses the forward motion of the engine to produce thrust. Since it produces no thrust when stationary (no ram air) ramjet-powered vehicles require an assisted take-off like a rocket assist to accelerate it to a speed where it begins to produce thrust. Ramjets work most efficiently at supersonic speeds around and can operate up to speeds of . Ramjets can be particularly useful in applications requiring a small and simple mechanism for high-speed use, such as missiles. The US, Canada, and UK had widespread ramjet powered missile defenses during the 1960s onward, such as the CIM-10 Bomarc and Bloodhound. Weapon designers are looking to use ramjet technology in artillery shells to give added range; a 120 mm mortar shell, if assisted by a ramjet, is thought to be able to attain a range of . They have also been used successfully, though not efficiently, as tip jets on the ends of helicopt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Comical History Of The States And Empires Of The Moon
''The Other World: Comical History of the States and Empires of the Moon'' (french: L’Autre monde ou les états et empires de la Lune) was the first of three satirical novels written by Cyrano de Bergerac. It was published posthumously in 1657 and, along with its companion work '' The States and Empires of the Sun'', is considered one of the earliest published science fiction stories. Arthur C. Clarke credited the book with the first description of rocket-powered spaceflight, and with the invention of the ramjet. Plot summary The book is narrated in the first person by a character also named Cyrano. Cyrano attempts to reach the Moon to prove there is a civilization that sees the Earth as its own moon. He launches himself into the sky from Paris by strapping bottles of dew to his body, but lands back on Earth. Believing he had traveled straight up and down, he is confused by local soldiers who tell him he is not in France; they escort him to the provincial governor who informs ...

International Astronautical Congress
Every year, the International Astronautical Federation with the support of the International Academy of Astronautics and the International Institute of Space Law (IISL), holds the International Astronautical Congress (IAC) which is hosted by one of the national society members of the IAF. They are an annual meeting of the actors in the discipline of space, and are generally held in late September or early October. They consist of plenary sessions, lectures and meetings. The IAC is attended by the agency heads and senior executives of the world's space agencies. As the Second World War came to an end, the United States and the Soviet Union held different and competing political worldviews. As the Cold War began to take shape, communication between the two countries became less frequent. Both countries turned their focus to achieving military superiority over the other.

Austro-Hungarian Army
The Austro-Hungarian Army (, literally "Ground Forces of the Austro-Hungarians"; , literally "Imperial and Royal Army") was the ground force of the Austro-Hungarian Dual Monarchy from 1867 to 1918. It was composed of three parts: the joint army (, "Common Army", recruited from all parts of the country), the Imperial Austrian Landwehr (recruited from Cisleithania), and the Royal Hungarian Honvéd (recruited from Transleithania). In the wake of fighting between the Austrian Empire and the Hungarian Kingdom and the two decades of uneasy co-existence following, Hungarian soldiers served either in mixed units or were stationed away from Hungarian areas. With the Austro-Hungarian Compromise of 1867 the new tripartite army was brought into being. It existed until the disestablishment of the Austro-Hungarian Empire following World War I in 1918. The joint "Imperial and Royal Army" ( or ''k.u.k.'') units were generally poorly trained and had very limited access to new equipment bec ...

Albert Fonó
Albert Fonó (born 2 July 1881 in Budapest, d. 21 November 1972 in Budapest), a successful Hungarian mechanical engineer who was one of the early pioneers of turbojet and ramjet propulsion and was first to patent a ramjet engine and a turbojet engine in 1928 (granted in 1932). Fonó graduated from the József Technical University in Budapest in 1903 and travelled widely, gaining experience working for German, Belgian, French and Swiss manufacturers, before attaining his Ph.D. His main specialty was energetics. He had 46 patents in 20 topics of research, including a steam boiler and an air compressor for mines. In 1915 he devised a solution for increasing the range of artillery, comprising a gun-launched projectile combined with a ramjet propulsion unit. This was to make it possible to obtain a long range with low initial muzzle velocities, allowing heavy shells to be fired from relatively lightweight guns. Fonó submitted his invention to the Austro-Hungarian Army but the propo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
René Lorin
René Lorin (24 March 1877 – 16 January 1933) was a French aerospace engineer and inventor of the ramjet. In 1908 Lorin patented the first subsonic ramjet design. He published the principles of a ramjet in articles in the journal ''L'Aérophile'' from 1908 to 1913, expressing the idea that the exhaust from internal combustion engines could be directed into nozzles to create jet propulsion. He could not test this invention since there was no way at the time for an aircraft to go fast enough for a ramjet to function properly. When René Leduc applied for a patent on a ramjet design in 1933, he discovered Lorin's publications and tried to contact him, only to learn that he had recently died. Leduc thereafter paid homage to Lorin's work. René Lorin is a graduate of the École Centrale Paris École Centrale Paris (ECP; also known as École Centrale or Centrale) was a French grande école in engineering and science. It was also known by its official name ''École Centrale des Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
