RS-82 Rocket
RS-82 and RS-132 (Reaktivny Snaryad; Russian: Реактивный Снаряд; rocket-powered projectile) were unguided rockets used by Soviet military during World War II. Development Design work on RS-82 and RS-132 rockets began in the late 1920s, by the Gas Dynamics Laboratory (GDL) led by Georgy Langemak, and including Nikolai Tikhomirov, Vladimir Artemiev, Boris Petropavlovsky, Yuriy Pobedonostsev, and others. The 82 mm (3.2 in) and 132 mm (5.2 in) diameters were chosen because the standard smokeless gunpowder charge used at the time was 24 mm (0.94 in) in diameter and seven of these charges fitted into an 82 mm cylinder. The first test-firing of a solid fuel rocket was carried out in March 1928, which flew for about 1,300 meters and in 1932 in-air test firings of RS-82 missiles from an Tupolev I-4 aircraft armed with six launchers successfully took place. In 1933 GDL became part of the Reactive Scientific Research Institute, where devel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocket (weapon)
In military terminology, a rocket is a self-propelled, generally unguided, weapon-system powered by a rocket engine. Though used primarily as medium- and long-range artillery systems, historically rockets have also seen considerable use as air-to-surface weapons, some use as air-to-air weapons, and even (in a few cases) as surface-to-air devices. Examples of modern surface-to-surface rocket systems include the Soviet BM-27 Uragan and the American M270 Multiple Launch Rocket System. In military parlance, a rocket differs from a missile primarily by lacking an active guidance system; early missiles became known as "guided rockets" or "guided missiles". Some rockets were developed as unguided systems and later upgraded to guided versions, like the GMLRS, and these generally retain the term "rocket" instead of becoming "missiles". Rockets or missiles that travel underwater, like the VA-111 Shkval, are known as "torpedoes", whatever their propulsion system. Early development The ...

Polikarpov R-5
The Polikarpov R-5 (russian: Р-5) was a Soviet reconnaissance bomber aircraft of the 1930s. It was the standard light bomber and reconnaissance aircraft of the Soviet Air Force for much of the 1930s, while also being used heavily as a civilian light transport, some 7,000 being built in total. Development and design The R-5 was developed by the design bureau led by Nikolai Nikolaevich Polikarpov А. С. Яковлев. О жизни и о себе (записки авиаконструктора). 2-е изд., доп. М., 1968. стр.159 as a replacement for the R-1 which served as the standard reconnaissance and light bomber aircraft with the Soviet Air Force. The prototype first flew in autumn 1928, powered by an imported German BMW VI V-12 engine. It was an unequal-span single-bay biplane of mainly wooden construction. After extensive evaluation, the R-5 entered production in 1930, powered by the Mikulin M-17, a licence-built copy of the BMW-VI, as a reconnaissance bombe ...

High Velocity Aircraft Rocket
The High Velocity Aircraft Rocket, or HVAR, also known by the nickname Holy Moses, was an American unguided rocket developed during World War II to attack targets on the ground from aircraft. It saw extensive use during both World War II and the Korean War. Design and development The HVAR was designed by engineers at Caltech during World War II as an improvement on the 5-Inch Forward Firing Aircraft Rocket (FFAR), which had a diameter warhead but an underpowered diameter rocket motor. The desire for improved accuracy from the flatter trajectory of a faster rocket spurred the rapid development. HVAR had a constant 5-inch diameter for both warhead and rocket motor, increasing propellant from of Ballistite. U.S. Ballistite propellant had a sea level specific impulse of over , compared with about for the British Cordite, German WASAG and Soviet PTP propellants. Hercules Powder Company was the principal U.S. supplier of high performance extruded Ballistite propellants: 51.5% nitr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angular Mil
A milliradian ( SI-symbol mrad, sometimes also abbreviated mil) is an SI derived unit for angular measurement which is defined as a thousandth of a radian (0.001 radian). Milliradians are used in adjustment of firearm sights by adjusting the angle of the sight compared to the barrel (up, down, left, or right). Milliradians are also used for comparing shot groupings, or to compare the difficulty of hitting different sized shooting targets at different distances. When using a scope with both mrad adjustment and a reticle with mrad markings (called an "mrad/mrad scope"), the shooter can use the reticle as a ruler to count the number of mrads a shot was off-target, which directly translates to the sight adjustment needed to hit the target with a follow up shot. Optics with mrad markings in the reticle can also be used to make a range estimation of a known size target, or vice versa, to determine a target size if the distance is known, a practice called "milling". Milliradian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Katyusha Rocket Launcher
The Katyusha ( rus, Катю́ша, p=kɐˈtʲuʂə, a=Ru-Катюша.ogg) is a type of rocket artillery first built and fielded by the Soviet Union in World War II. Multiple rocket launchers such as these deliver explosives to a target area more intensively than conventional artillery, but with lower accuracy and requiring a longer time to reload. They are fragile compared to artillery guns, but are cheap, easy to produce, and usable on almost any chassis. The Katyushas of World War II, the first self-propelled artillery mass-produced by the Soviet Union,Zaloga, p 150. were usually mounted on ordinary trucks. This mobility gave the Katyusha, and other self-propelled artillery, another advantage: being able to deliver a large blow all at once, and then move before being located and attacked with counter-battery fire. Katyusha weapons of World War II included the BM-13 launcher, light BM-8, and heavy BM-31. Today, the nickname ''Katyusha'' is also applied to newer truck-mounte ...

Tupolev SB
The Tupolev ANT-40, also known by its service name Tupolev SB (russian: Скоростной бомбардировщик – ''Skorostnoi Bombardirovschik'' – high speed bomber) and development co-name TsAGI-40, was a high speed twin-engined three-seat monoplane bomber, first flown in 1934. The Tupolev design was advanced but lacked refinement, much to the dismay of crews, maintenance personnel, and Stalin, who pointed out that "there are no trivialities in aviation". Numerically the most important bomber in the world in the late 1930s, the SB was the first modern stressed skin aircraft produced in quantity in the Soviet Union and probably the most formidable bomber of the mid-1930s. It was produced in the Soviet Union and was also built under license in Czechoslovakia. Many versions saw extensive action in Spain, the Republic of China, Mongolia, Finland and at the beginning of World War II against Germany in 1941. It was also used in various duties in civil variants, as tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Battle Of Khalkhin Gol
The Battles of Khalkhin Gol (russian: Бои на Халхин-Голе; mn, Халхын голын байлдаан) were the decisive engagements of the undeclared Soviet–Japanese border conflicts involving the Soviet Union, Mongolia, Japan and Manchukuo in 1939. The conflict was named after the river Khalkhin Gol, which passes through the battlefield. In Japan, the decisive battle of the conflict is known as the after Nomonhan, a nearby village on the border between Mongolia and Manchuria. The battles resulted in the defeat of the Japanese Sixth Army. Background After the Japanese occupation of Manchuria in 1931, Japan turned its military interests to Soviet territories that bordered those areas. The first major Soviet-Japanese border incident, the Battle of Lake Khasan, occurred in 1938 in Primorye. Clashes between Japanese and Soviet forces occurred frequently along the border of Manchuria. In 1939, Manchuria was a puppet state of Japan known as Manchukuo, and Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1939 In Aviation

Air-to-air Rocket
An air-to-air rocket or air interception rocket is an unguided projectile fired from aircraft to engage other flying targets. They were used briefly in World War I to engage enemy observation balloons and in and after World War II to engage enemy bombers. Fighters were too maneuverable to be effectively engaged with rockets. History World War I Rockets were used in World War I to engage observation balloons and airships. Success rates were low and the rockets were dangerous to handle in the early fighters built from highly flammable materials. By the end of the war they were replaced by the incendiary Pomeroy bullets. The Pomeroy bullet was developed to strike German Zeppelin airships, by igniting the hydrogen in the balloon. They did not always work. One of the notable rockets from World War I was the Le Prieur rocket which had a range of about , limited by inaccuracy. It was first used in the Battle of Verdun.

Soviet Air Force
The Soviet Air Forces ( rus, Военно-воздушные силы, r=Voyenno-vozdushnyye sily, VVS; literally "Military Air Forces") were one of the air forces of the Soviet Union. The other was the Soviet Air Defence Forces. The Air Forces were formed from components of the Imperial Russian Air Service in 1917, and faced their greatest test during World War II. The groups were also involved in the Korean War, and dissolved along with the Soviet Union itself in 1991–92. Former Soviet Air Forces' assets were subsequently divided into several air forces of former Soviet republics, including the new Russian Air Force. "March of the Pilots" was its song. Origins The ''All-Russia Collegium for Direction of the Air Forces of the Old Army'' (translation is uncertain) was formed on 20 December 1917. This was a Bolshevik aerial headquarters initially led by Konstantin Akashev. Along with a general postwar military reorganisation, the collegium was reconstituted as the "Workers' an ...
