Airplanes And Rocket Engines

In 1942 he flew the first airplane with a liquid rocket engine in the USSR. First jet aircraft existed only as a war – which is understandable, high speed, which gives an advantage that way. But with 50s and they are in everyday life use, as civilian aircraft. In 1955 there was a breakthrough in the development of helicopters. But where such a jump? For a start it was organized through the efforts of the authorities of the USSR. How? For example, in 1919 appeared the first educational institution for training engineers and aircraft manufacturers.

Initially it was just a school. But a year later he renamed the Institute, which enabled him to give more higher education graduates. The development of this time could be described as modernized. Get more background information with materials from Timepieces. That is, it was mainly based on modernization and mass production of the best examples of aircraft of foreign brands, and also were working on creating your own designs. By the early forties, several new plants for the production of aircraft, both passenger and military. However, it should be noted that great attention is paid military aircraft, as even at that time almost the Great Patriotic War, as well. WWII was already in full swing … Time flies, and came in 1948.

For the first time was achieved in the USSR, the speed of sound in flight with a decline – new step of development. And in 1950. is in horizontal flight, MiG-17, Yak-50 were 'sound barrier'. But all is nothing in two years MiG-19 developed a speed of 1.5 times greater than the speed of sound, but the most pleasant, happy and that leadership and just designers – superior to the main characteristics of the 'SUPER-SEIBR'. And if you know 'SUPER-SEIBR' – this is the main fighter in the U.S. at that time. But the designers did not stop there. They tried to give new strength, new impetus to the development constantly feeding aviakonstruktsiyu new discoveries. The next high-speed dash was made in 1960 on May 29. T-405 aircraft has broken all records – 2048 miles per hour! As a result of this aircraft since the plane had already received military at 3000 km per hour. The USSR continued to demonstrate their successes around the world, so in 1988 in England, then in 1989 – Paris. However, the development of jet aircraft ended as abruptly as the classical aviakonstruktsii. What further development? That will give us the future? What should be done for further development? Maybe just aviation, and especially the military requires a new discovery, but a new era of discovery …

The Rapid

Were practically implemented dented lamp (also tested and helical), providing sufficient mechanical strength of the structure. Dents have been made as a tube with one hand and alternately from opposite sides. Dents on the part of the discharge are the projections included in the plasma. In such a tube is lengthened effective way to discharge (approximately 20%), increases the ratio of perimeter to cross section and decreases the average path of photons in the plasma. Thanks to obtain higher values of E and T and improved yield of UV radiation. Welts (edge) of dents due to the lower current density of these zones are less heated and cold zones. With proper selection of the form they have a temperature optimum in terms of mercury vapor pressure.

The initial light output of these lamps was 5-10% higher than comparable round tubes. However, the decline in flux with time is much faster, so that the average light output fluorescent tubes with dents are noticeably lower. Rapid decline in flow was due to a very large non-uniformity of the density of irradiation, ion bombardment and heating of the cross section. In the center of the projections (dents) density is ten times higher than the average density in the tube with a circular cross section, which led to the rapid growth processes of destruction of the phosphor. This, as well as a substantial complexity of manufacturing led to These lamps do not have distribution. Methods for maintaining optimum mercury vapor pressure at high w. In the lamps operating at temperatures above the flask 50-60 C, the optimum mercury vapor pressure can be achieved r0pt by maintaining a small area of the bulb at a lower temperature corresponding to r0t, or by the use of mercury amalgams, have a lower vapor pressure of mercury. Cold spots can be obtained by increasing the heat from the outer surface of the lamp, or by reducing the flow of heat to a small section of the bulb inside, or both one and the other way.
