Tupolev Tu-104B
The Tupolev Tu-104 (NATO reporting name: Camel) is a retired twinjet, medium-range, narrow-body turbojet-powered Soviet airliner. It was the second to enter regular service, behind the British de Havilland Comet, and was the only jetliner operating in the world from 1956 to 1958, when the British jetliner was grounded due to safety concerns. In 1957, Czechoslovak Airlines – ČSA, (now Czech Airlines) became the first airline in the world to fly a route exclusively with jet airliners, using the Tu-104A variant between Prague and Moscow. In civil service, the Tu-104 carried over 90 million passengers with Aeroflot (then the world's largest airline), and a lesser number with ČSA, while it also was operated by the Soviet Air Force. Its successors included the Tu-124, Tu-134, and Tu-154. Design and development At the beginning of the 1950s, the Soviet Union's Aeroflot airline needed a modern airliner with better capacity and performance than the piston-engined aircraft then ...

Ilyushin Il-28
The Ilyushin Il-28 (russian: Илью́шин Ил-28; NATO reporting name: Beagle) is a jet aircraft, jet bomber of the immediate postwar period that was originally manufactured for the Soviet Air Forces. It was the Soviet Union's first such aircraft to enter large-scale production. It was also licence-built in China as the Harbin H-5. Total production in the USSR was 6,316 aircraft, and over 319 H-5s were built. Only 187 examples of the HJ-5 training variant were manufactured. In the 1990s hundreds remained in service with various air forces over 50 years after the Il-28 first appeared. The only H-5s in service currently are approximately 80 aircraft which operate with the Korean People's Air Force. The Il-28 has the USAF/DoD reporting name "Type 27"Parsch, Andreas and Aleksey V.

Lace
Lace is a delicate fabric made of yarn or thread in an open weblike pattern, made by machine or by hand. Generally, lace is divided into two main categories, needlelace and bobbin lace, although there are other types of lace, such as knitted or crocheted lace. Other laces such as these are considered as a category of their specific craft. Knitted lace, therefore, is an example of knitting. This article considers both needle lace and bobbin lace. While some experts say both needle lace and bobbin lace began in Italy in the late 1500s, there are some questions regarding its origins. Originally linen, silk, gold, or silver threads were used. Now lace is often made with cotton thread, although linen and silk threads are still available. Manufactured lace may be made of synthetic fiber. A few modern artists make lace with a fine copper or silver wire instead of thread. Etymology The word lace is from Middle English, from Old French ''las'', noose, string, from Vulgar Latin *' ...

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Mahogany
Mahogany is a straight-grained, reddish-brown timber of three tropical hardwood species of the genus ''Swietenia'', indigenous to the AmericasBridgewater, Samuel (2012). ''A Natural History of Belize: Inside the Maya Forest''. Austin: University of Texas Press. pp. 164–165. . and part of the pantropical chinaberry family, Meliaceae. Mahogany is used commercially for a wide variety of goods, due to its coloring and durable nature. It is naturally found within the Americas, but has also been imported to plantations across Asia and Oceania. The mahogany trade may have begun as early as the 16th century and flourished in the 17th and 18th centuries. In certain countries, mahogany is considered an invasive species. Description The three species are: *Honduran or big-leaf mahogany ('' Swietenia macrophylla''), with a range from Mexico to southern Amazonia in Brazil, the most widespread species of mahogany and the only genuine mahogany species commercially grown today.

Drag Parachute
A drogue parachute is a parachute designed for deployment from a rapidly-moving object. It can be used for various purposes, such as to decrease speed, to provide control and stability, or as a pilot parachute to deploy a larger parachute. Vehicles that have used drogue parachutes include multi-stage parachutes, aircraft, and spacecraft recovery systems. The drogue parachute was invented by the Russian professor and parachute specialist Gleb Kotelnikov in 1912, who also invented the knapsack parachute. The Soviet Union introduced its first aircraft fitted with drogue parachutes during the mid 1930s; use of the technology expanded during and after the Second World War. A large number of jet-powered aircraft have been furnished with drogue parachutes, including the Boeing B-52 Stratofortress strategic bomber and the Eurofighter Typhoon multirole aircraft; they were also commonly used within crewed space vehicle recovery programmes, including Project Mercury and Project Gemini. ...

Tupolev Tu-154
The Tupolev Tu-154 (russian: Tyполев Ту-154; NATO reporting name: "Careless") is a three-engined, medium-range, narrow-body airliner designed in the mid-1960s and manufactured by Tupolev. A workhorse of Soviet and (subsequently) Russian airlines for several decades, it carried half of all passengers flown by Aeroflot and its subsidiaries (137.5 million/year or 243.8 billion passenger-km in 1990), remaining the standard domestic-route airliner of Russia and former Soviet states until the mid-2000s. It was exported to 17 non-Russian airlines and used as a head-of-state transport by the air forces of several countries. The aircraft has a cruising speed of and a range of . Capable of operating from unpaved and gravel airfields with only basic facilities, it was widely used in the extreme Arctic conditions of Russia's northern/eastern regions, where other airliners were unable to operate. Originally designed for a 45,000-hour service life (18,000 cycles), but capable of 80, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tupolev Tu-134
The Tupolev Tu-134 (NATO reporting name: Crusty) is a twin-engined, narrow-body jet airliner built in the Soviet Union for short and medium-haul routes from 1966 to 1989. The original version featured a glazed-nose design and, like certain other Russian airliners (including its sister model the Tu-154), it can operate from unpaved airfields. One of the most widely used aircraft in former Comecon countries, the number in active service is decreasing because of operational safety concerns and noise restrictions. The model has seen long-term service with some 42 countries, with some European airlines having scheduled as many as 12 daily takeoffs and landings per plane. In addition to regular passenger service, it has also been used in various air force, army and navy support roles; for pilot and navigator training; and for aviation research and test projects. In recent years, a number of Tu-134s have been converted for use as VIP transports and business jets. A total of 854 Tu-1 ...
