Strategic bomber b-52 STRATOFORTRESS. Contest project of a new reagent tion of the strategic bomber to replace the CONVAIR piston-IN-36 were announced, the U.S. air force in 1946. Despite the fact that some high-ranking air force officers did not believe in the possibility of the construction of a heavy jet with a range of over 13,000 km, company Boeing, Convair and Douglas enthusiastically set to work.
When a brilliant businessman errett Cord Lobben included in the 20-ies of the last century in his financial Empire small firm Duesenberg Motors, he first instructed the members of our talented designers, engineers and businessmen, the brothers Friedrich and August Dusenberg, regardless of the cost, to create the best car in the world.
“Could you tell us about how to make a sports bow?”. George Grudev (Bulgaria), Nikolay Kuznetsov (Kursk) etc. to Make a sports bow by all the rules that only an experienced master. But there is a solution, and pretty simple: onions can be made, for example, old… skiing.
The Tu-22 was designed to replace the Tu-16. The design of the new aircraft under the symbol “105” was initiated in the Tupolev 15 August 1955 and August 1957 was completed construction of the prototype. 21 Jun 1958 “105” made its first flight. Since 1957, he designed an improved prototype, “105A”, which became the prototype of the Tu-22. The Tu-22 were built at the Kazan plant № 22 from the beginning of 1959 to December 1969. It was built 311 aircraft of this type (modification of the Tu-22 and Tu-22B, scout the Tu-22R, Tu-22K, jammer Tu-22P and training aircraft Tu-22U).
By the early 1930s, one of the centers of the nascent Soviet motorcycle could be the city of Kharkov. Here in the capital of Soviet Ukraine, on the territory of the former sugar factory was organized car Assembly plant – HAZ, was introduced in the “Automotiveaddicts” Association “Ukrnet”.
Information stored in the computer, it is sometimes necessary to put on paper. The result typically looks like a stack of A4 sheets, stapled one side with a stapler. But easier would be to have a printout in the form of smaller format books, a small notebook of nested into each other bent sheets, or (if the pages of many) of several such notebooks, stitched together. How can that be?
The simultaneous launching of multiple model rocket engines presents a great challenge for modelers. Existing methods of ignition have several disadvantages; Perekrest does not allow you to launch multiple missiles for a short time (as the products of combustion clogging the tubes, burn the ends, etc.), as currently practiced method of ignition with the banks is a danger of explosion engines because of the filling of channel MRD pyrotechnic compositions.
Last spring I made myself water skiing. But to slip on them could rarely, as the role of the tug performed… a motorcycle with a sidecar. The construction of special boats would require a certain cost, powerful engines, and most importantly – time.
This machine is not only powerful and roomy I was able to fairly compactly arrange all of its aggregates, making the frame left plenty of room for the passengers and even any cargo, including bulk or lengthy — it is a body of 250 kg, the trailer for 1 ton and wheeled console.
Model submarine class EATING has always been one of the most interesting, especially for juniors. Such “free-floating” model require from the constructor of ship models awareness of the ships are prototypes, ability to work with the most modern materials and equipment, knowledge of basic fluid dynamics, electrical engineering and electronics.
