Junkers EF 125
The Junkers Ju 287 was an aerodynamic testbed built in Nazi Germany to develop the technology required for a multi-engine jet bomber. It was powered by four Junkers Jumo 004 engines, featured a novel forward-swept wing, and apart from the wing was assembled largely from components scavenged from other aircraft. It was one of the very few jet propelled aircraft ever built with fixed landing gear. Development The Ju 287 was intended to provide the ''Luftwaffe'' with a bomber that could avoid interception by outrunning enemy fighters. The swept-forward wing was suggested by the project's head designer Dr. Hans Wocke as a way of providing extra lift at low airspeeds - necessary because of the poor responsiveness of early turbojets at the vulnerable times of takeoff and landing. A further structural advantage of the forward-swept wing was that it would allow for a single massive weapons bay in the best location, the centre of gravity of the plane, with the main wing spar pas ...

B-24 Liberator
The Consolidated B-24 Liberator is an American heavy bomber, designed by Consolidated Aircraft of San Diego, California. It was known within the company as the Model 32, and some initial production aircraft were laid down as export models designated as various LB-30s, in the Land Bomber design category. At its inception, the B-24 was a modern design featuring a highly efficient shoulder-mounted, high aspect ratio Davis wing. The wing gave the Liberator a high cruise speed, long range and the ability to carry a heavy bomb load. Early RAF Liberators were the first aircraft to cross the Atlantic Ocean as a matter of routine. In comparison with its contemporaries, the B-24 was relatively difficult to fly and had poor low-speed performance; it also had a lower ceiling and was less robust than the Boeing B-17 Flying Fortress. While aircrews tended to prefer the B-17, General Staff favored the B-24 and procured it in huge numbers for a wide variety of roles. At approximately 18,5 ...

Junkers Ju 352
The Junkers Ju 352 ''Herkules'' ("Hercules" in German) was a German World War II transport aircraft that was developed from the Junkers Ju 252. Design and development During the late spring of 1942, the Junkers-Dessau project office was instructed by the Reich Air Ministry (RLM) to investigate the possibility of redesigning the structure of the Junkers Ju 252 transport to make maximum use of non-strategic materials, replacing the Junkers Jumo 211F engines of the Ju 252 with Bramo 323R radial engines. The result followed closely the aerodynamic design of the Ju 252 but was an entirely new aircraft. The wing of the Ju 352 was similar in outline to that of the Ju 252 but, mounted further aft on the fuselage, was entirely of wooden construction. The Ju 352 also had a similar ''Trapoklappe'' ("Transportklappe", rear loading ramp) to that of the Ju 252. The ramp allowed the loading of vehicles or freight into the cargo hold while holding the fuselage level. In general, the Ju 352 was co ...

Junkers Ju 188
The Junkers Ju 188 was a German ''Luftwaffe'' high-performance medium bomber built during World War II, the planned follow-up to the Ju 88 with better performance and payload. It was produced only in limited numbers, due both to the presence of improved versions of the Ju 88, as well as the increasingly effective Allied strategic bombing campaign against German industry and the resulting focus on fighter production. Background In 1936, Junkers submitted proposals for the Ju 85 and Ju 88 into competition for the new standardized ''Luftwaffe'' high-speed tactical bomber, known as the ''Schnellbomber'' (fast bomber). The two designs were almost identical, differing only in that the Ju 85 used a twin-rudder and the Ju 88 a single fin. At the same time, they offered modified versions of each as the Ju 85B and Ju 88B, again similar to the original designs but using an "egg shaped" stepless cockpit forward fuselage design that comprised a greenhouse-like, well-framed network of some ...

Heinkel He 177
The Heinkel He 177 ''Greif'' (Griffin) was a long-range heavy bomber flown by the ''Luftwaffe'' during World War II. The introduction of the He 177 to combat operations was significantly delayed, by both problems with the development of its engines, and frequent changes to its intended role. Nevertheless, it was the only long-range, heavy bomber to become operational with the ''Luftwaffe'' during the war. The He 177 had a payload/range capability similar to that of four-engined heavy bombers used by the Allies in the European theatre. Work on the design began in response to a 1936 requirement, known as Bomber A, issued by the RLM for a purely strategic bomber. Thus the He 177 was intended originally to be capable of a sustained bombing campaign against Soviet manufacturing capacity, deep inside Russia. In contrast to its heavy payload and very wide, planform, the specifications called for the design to have only two very powerful engines. To deliver the power ...

Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye. Geodesic construction Geo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prague
Prague ( ; cs, Praha ; german: Prag, ; la, Praga) is the capital and largest city in the Czech Republic, and the historical capital of Bohemia. On the Vltava river, Prague is home to about 1.3 million people. The city has a temperate oceanic climate, with relatively warm summers and chilly winters. Prague is a political, cultural, and economic hub of central Europe, with a rich history and Romanesque, Gothic, Renaissance and Baroque architectures. It was the capital of the Kingdom of Bohemia and residence of several Holy Roman Emperors, most notably Charles IV (r. 1346–1378). It was an important city to the Habsburg monarchy and Austro-Hungarian Empire. The city played major roles in the Bohemian and the Protestant Reformations, the Thirty Years' War and in 20th-century history as the capital of Czechoslovakia between the World Wars and the post-war Communist era. Prague is home to a number of well-known cultural attractions, many of which survived the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Letov Kbely
Letov is an aircraft company located in Letňany, Prague, Czech Republic. It is the oldest aircraft company in the region. History Letov was founded in 1918 by the Czechoslovak Ministry of Defense to repair World War I trophy planes. The first indigenous aircraft, the Letov Š-1, was designed and built in 1920, and some 50 aircraft types were built by 1939. During World War II the factory served as repair shop for the German Luftwaffe. Production lines were also set up during World War II for combat versions of the Ju 290 aircraft, commencing with the Ju 290 A-2, which carried a search radar for its patrol role. Since the 1950s, the plant has manufactured parts for the MiG-15, MiG-19 and MiG-21. Over 4,000 wings and empennages for L-29 Delfín, a jet trainer aircraft that became the standard jet trainer for the air forces Warsaw Pact nations in the 1960s, were built by Letov. The company has also built wings and empennages for 2500 L-39 Albatros trainer aircraft since the 197 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bomb Bay
The bomb bay or weapons bay on some military aircraft is a compartment to carry bombs, usually in the aircraft's fuselage, with "bomb bay doors" which open at the bottom. The bomb bay doors are opened and the bombs are dropped when over the target or at a specified launching point. History and function Bomb bays were born of necessity. Early military aircraft suffered severe aerodynamic drag (which would further slow down the already lumbering bomb-laden aircraft) with bombs hanging from the wings or below the fuselage, so military aviation designers moved the bombs inside the aircraft. Before the introduction of stealth technology bomb bays were mostly used by dedicated bomber aircraft; in fighters and attack airplanes bombs and rockets were hung from the wings or fuselage on pylons. Notable exceptions are the F-101, F-102 and F-106 interceptor aircraft, all of which had bays used to store missiles, or other weapons stores. Today many designers have moved previously "e ...
