Tupolev Tu-16
The Tupolev Tu-16 (USAF/DOD reporting name Type 39; NATO reporting name: Badger) is a twin-engined jet strategic heavy bomber used by the Soviet Union. It has been flown for almost 70 years. While many aircraft in Soviet service were retired after the Cold War ended, the Chinese license-built version Xian H-6 remains in service with the People's Liberation Army Air Force, with the most modern variant, the H-6K, still being actively produced . Development In the late 1940s, the Soviet Union was strongly committed to matching the United States in strategic bombing capability. The Soviets' only long-range bomber at the time was Tupolev's Tu-4 "Bull", a reverse-engineered copy of the American B-29 Superfortress. The development of the notably powerful Mikulin AM-3 turbojet led to the possibility of a large, jet-powered bomber. The Tupolev design bureau began work on the Tu-88 ("Aircraft N") prototypes in 1950. The Tu-88 first flew on 27 April 1952. After winning a competition ...

Twinjet
A twinjet or twin-engine jet is a jet aircraft powered by two jet engine, engines. A twinjet is able to fly well enough to land with a single working engine, making it safer than a single-engine aircraft in the event of failure of an engine. Fuel efficiency of a twinjet is better than that of aircraft with more engines. These considerations have led to the widespread use of aircraft of all types with twin engines, including airliners, fixed-wing military aircraft, and others. Aircraft configurations There are three common configurations of twinjet aircraft. The first, common on large aircraft such as airliners, has a podded engine usually mounted beneath, or occasionally above or within, each wing. Most notable examples of such a configuration are the Boeing 737 and Airbus A320. The second has one engine mounted on each side of the rear fuselage, close to its empennage, used by many business jets, although some airliners like the Fokker 70, Douglas DC-9 and COMAC ARJ21 utilise ...

Ilyushin Il-46
__NOTOC__ The Ilyushin Il-46 was a jet-engined bomber produced in the USSR during 1951-2, as the result of a directive to redesign the Ilyushin Il-42, Il-42 project (half the drawings had already been completed). The revised specification was for an aircraft with twice the range and 1 1/2 times the bomb load, with a prototype ready to be submitted for state acceptance trials in July 1952. The Ilyushin design bureau set about designing two versions of the same aircraft, the straight-wing (Il-46) and the swept-wing (Il-46S), with as much as possible common to both aircraft. To meet the schedule for state acceptance trials Ilyushin built only the straight-wing version, fearing that the design, manufacture and flying characteristics of the swept-wing aircraft might cause delays. Design and development The airframe, constructed of aluminium alloy with steel used in highly stressed parts, resembled a large Ilyushin Il-28, Il-28, the long fuselage having swept tail surfaces, and a simila ...

Turbojet
The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor). The compressed air from the compressor is heated by burning fuel in the combustion chamber and then allowed to expand through the turbine. The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust. Two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently into practical engines during the late 1930s. Turbojets have poor efficiency at low vehicle speeds, which limits their usefulness in vehicles other than aircraft. Turbojet engines have been used in isolated cases to power vehicles other than aircraft, typically for attempts on land speed records. Where vehicles are "turbine-powere ...

Mikulin AM-3
The Mikulin AM-3 (also called RD-3M) was a turbojet engine developed in the Soviet Union by Alexander Mikulin.Gunston 1989, p. 104. Design and development The development of the high-performance single-shaft engine began in 1948. The engine was used in different versions for the Tupolev Tu-16 and Tu-104, as well as the Myasishchev M-4. It had a single-stage low-pressure and an eight-stage high-pressure compressor, powered by a two-stage high-pressure turbine. Variants ;AM-3: first series version ;AM-3A: ;AM-3D: Version for M-4 with thrust ;AM-3M-200: AM-3M-500, AM-3M-500A: developed further versions with ;WP-8: Chinese copy of the AM-3 with thrust for the Xian H-6 The Xi'an H-6 ( zh, c=轰-6, p=Hōng-6) is a twin-engine jet bomber of the Chinese People's Liberation Army Air Force (PLAAF).

B-29 Superfortress
The Boeing B-29 Superfortress is a retired American four-engined Propeller (aeronautics), propeller-driven heavy bomber, designed by Boeing and flown primarily by the United States during World War II and the Korean War. Named in allusion to its predecessor, the Boeing B-17 Flying Fortress, the Superfortress was designed for high-altitude strategic bomber, strategic bombing, but also excelled in low-altitude night incendiary bombing, and in dropping naval mines to blockade Japan. B-29s dropped the atomic bombings of Hiroshima and Nagasaki, atomic bombs on Hiroshima and Nagasaki, the only aircraft ever to drop nuclear weapons in combat. One of the largest aircraft of World War II, the B-29 was designed with state-of-the-art technology, which included a cabin pressurization, pressurized cabin, dual-wheeled tricycle landing gear, and an analog computer-controlled fire-control system that allowed one gunner and a fire-control officer to direct four remote machine gun turrets.

Reverse Engineering
Reverse engineering (also known as backwards engineering or back engineering) is a process or method through which one attempts to understand through deductive reasoning how a previously made device, process, system, or piece of software accomplishes a task with very little (if any) insight into exactly how it does so. Depending on the system under consideration and the technologies employed, the knowledge gained during reverse engineering can help with repurposing obsolete objects, doing security analysis, or learning how something works. Although the process is specific to the object on which it is being performed, all reverse engineering processes consist of three basic steps: information extraction, modeling, and review. Information extraction is the practice of gathering all relevant information for performing the operation. Modeling is the practice of combining the gathered information into an abstract model, which can be used as a guide for designing the new object or syst ...

Tupolev Tu-4
The Tupolev Tu-4 (; NATO reporting name: Bull) is a piston-engined Soviet Union, Soviet strategic bomber that served the Soviet Air Force from the late 1940s to the mid-1960s. The aircraft was a copy of the American Boeing B-29 Superfortress, having been Reverse engineering, reverse-engineered from seized aircraft that had made emergency landings in the USSR. Design and development Toward the end of World War II, the Soviet Union saw the need for a strategic bombing capability similar to that of the Western Allies. The Soviet VVS air arm had the locally designed Petlyakov Pe-8 four-engined "heavy" in service at the start of the war, but only 93 had been built by the end of the war and the type had become obsolete. The U.S. regularly conducted Air raids on Japan, bombing raids on Japan from distant Pacific forward bases using B-29 Superfortresses. Joseph Stalin ordered the development of a comparable bomber. The U.S. twice refused to supply the Soviet Union with B-29s under Lend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strategic Bombing
Strategic bombing is a systematically organized and executed military attack from the air which can utilize strategic bombers, long- or medium-range missiles, or nuclear-armed fighter-bomber aircraft to attack targets deemed vital to the enemy's war-making capability. It is a military strategy used in total war with the goal of defeating the enemy by destroying its morale, its economic ability to produce and transport materiel to the Theater (warfare)#Theater of operations, theatres of military operations, or both. The term terror bombing is used to describe the strategic bombing of civilian targets without military value, in the hope of damaging an enemy's morale. One of the strategies of war is to demoralization (warfare), demoralize the enemy so that peace or surrender becomes preferable to continuing the conflict. Strategic bombing has been used to this end. The phrase "terror bombing" entered the English lexicon towards the end of World War II and many strategic bombing cam ...
