Engine Gun
An engine gun, or engine cannon (from , "motor cannon"), is an List of aircraft weapons, aircraft gun mounted behind and through the cylinder block of an Inline engine (aeronautics), inline aircraft engine (most often a V engine) with a reduction drive that displaces the propeller axle to be in line with the gun so that gunfire is allowed through the propeller hub. This allows for nose-mounted weaponry on aircraft without the need for synchronization gear while also permitting higher calibers for nose-mounted weaponry, which otherwise would be hard to adapt for synchronization gear. The first time this was done was during World War I when the French modified the Hispano-Suiza 8 engine to be able to install a 37 mm autocannon. The concept was used widely before the Jet Age.

Hispano-Suiza HS
Hispano-Suiza () is a Spanish automotive company. It was founded in 1904 by Marc Birkigt and as an automobile manufacturer and eventually had several factories in Spain and France that produced luxury cars, aircraft engines, trucks and weapons. In 1923, its French luxury car arm became a semi-autonomous partnership with the Spanish parent company. In 1946, the parent company sold all of its Spanish automotive assets to Enasa, a Spanish state-owned vehicle manufacturer, and the French arm continued as an independent aviation engine and components manufacturer under the Hispano-Suiza name. In 1968, Hispano-Suiza was taken over by the aerospace company Snecma, which is now part of the French Safran Group. The relaunch of Hispano Suiza Cars has been made by the same founding family (4th generation of the Suqué Mateu Family), the company is part of the Peralada Group (owned as well by the Suqué Mateu family) in 2019 with a fully-electric 1,119 HP hypercar called Hispano-Suiza ...

Oerlikon FF
The FF were a series of 20mm autocannon introduced by Oerlikon in the late 1920s. The name comes from the German term ''Flügel Fest'', meaning ''wing mounted, fixed'', being one of the first 20mm guns to be small and light enough to fit into a fighter aircraft's wing. The FF series inspired many 20mm cannon used in World War II, including the Hispano-Suiza HS.404 (adopted by the French, British and U.S. forces), the German MG FF, and the Japanese IJNAS's Type 99 cannon. Design The basic design was based on the original Oerlikon 20 mm cannon, in turn based on the German Empire's Becker 20 mm cannon of World War I. In the post-war period, Oerlikon had developed the original design to produce three autocannons with increasingly powerful rounds; the original model, later known as the "F", used the Becker 20x70mm round, the newer "L" model used a 20x100 round, and finally the "S" model used a 20x110. All of these weapons used the API blowback operational principle. In 1935 Oerlikon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nudelman-Suranov NS-45
The Nudelman-Suranov NS-45 was an enlarged version of the Soviet Nudelman-Suranov NS-37 aircraft autocannon. It was evaluated for service on 44 Yakovlev Yak-9K aircraft during World War II, but proved to stress the airframes too much. The NS-45 was also mounted on the prototype Tupolev Tu-1 night fighter after the end of World War II. Design and development The NS-45 was created as a result of a July 1943 decision of the State Defense Committee to arm Soviet fighters with 45 mm autocannons. As with the 37 mm autocannons already installed in some Soviet and lend-lease single-engine fighters, the intended method of installation of the 45 mm gun was to have its barrel pass through the engine block and the empty propeller shaft, in this case that of the Yak-9. Consequently, the main difficulty in designing the 45 mm autocannon was the limitation imposed by the engine blocks available for this aircraft. Accounting for the diameter of the 45 mm shell, the Y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nudelman N-37
The Nudelman N-37 was a 37 mm (1.46 in) aircraft autocannon used by the Soviet Union. It was designed during World War II by V. Ya. Nemenov of Alexander Nudelman, A.E. Nudelman's OKB-16 to replace the earlier Nudelman-Suranov NS-37 and entered service in 1946. It was 30% lighter than its predecessor at the cost of a 23% lower muzzle velocity. The N-37 was a sizable weapon firing a massive (735 g/26 oz HEI-T, 760 g/27 oz AP-T) shell. Its muzzle velocity was still considerable, but its rate of fire was only 400 rounds per minute. The weapon's considerable recoil and waste gases were problematic for turbojet fighter aircraft, as was finding space for the gun and a useful amount of ammunition, but a single shell was often sufficient to destroy a bomber. The N-37 was used in the MiG-9, MiG-15, MiG-17, and early MiG-19 fighters, the Yakovlev Yak-25, and others. Production lasted through the late 1950s, although it remained in service for many years afterwar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nudelman-Suranov NS-37
The Nudelman-Suranov NS-37 () was a aircraft cannon, which replaced the unreliable Shpitalny Sh-37 gun. Large caliber was planned to allow destruction of both ground targets (including armoured ones) and planes (ability to shoot down a bomber with a single hit). Developed by A. E. Nudelman and A. Suranov from OKB-16 Construction Bureau from 1941, it was tested at the front in 1943 and subsequently ordered into production, which lasted until 1945. It was used on the LaGG-3 and Yak-9T fighter planes (mounted between the vee of the engine, in ''motornaya pushka'' mounts) and Il-2 ground attack planes (in underwing pods). Although the heavy round offered large firepower, the relatively low rate of fire and heavy recoil made hitting targets difficult. While pilots were trained to fire short bursts, on light aircraft only the first shot was truly aimed. Additionally, penetration of medium and heavy tanks' top armour was possible only at high angles (above 40 degrees), which was ha ...

Nudelman-Suranov NS-23
The NS-23 was a aircraft cannon designed by A. E. Nudelman, A. Suranov, G. Zhirnykh, V. Nemenov, S. Lunin, and M. Bundin during World War II as a replacement for the Volkov-Yartsev VYa-23 cannon. It entered service in 1944. The NS-23 round was derived from the 14.5×114mm anti-tank round by necking it out to 23 mm. A synchronized version, designated NS-23S (for ''synchronized''), was used for fixed installations firing through the propeller arc. Applications of the NS-23 included the Antonov An-2, Ilyushin Il-10, Ilyushin Il-22, Lavochkin La-9, La-15, MiG-9, Yak-9UT, Yak-15, Yak-17, Yak-23, and Tu-4. Some early MiG-15s were also equipped with the NS-23. The NS-23 was replaced in service by the Nudelman-Rikhter NR-23 The Nudelman-Richter NR-23 is a Soviet autocannon widely used in military aircraft of the Soviet Union and Warsaw Pact. It was designed by A. E. Nudelman and A. A. Richter to replace the wartime Nudelman-Suranov NS-23 and Volkov-Yartsev VYa-2 ... aro ...

ShVAK Cannon
The ShVAK (, "Shpitalny-Vladimirov Aviation Large-calibre") was a 20 mm autocannon used by the Soviet Union during World War II. It was designed by Boris Shpitalniy and Semyon Vladimirov and entered production in 1936. ShVAK were installed in many models of Soviet aircraft. The TNSh was a version of the gun produced for light tanks (). ShVAK shares the name with its 12.7 mm heavy machine gun predecessor. Development and production 12.7x108mm ShVAK The development of the 12.7 mm ShVAK was in response to a Soviet government decree passed on 9 February 1931, directing domestic manufacturers to produce an aircraft machine gun for the 12.7×108mm cartridge that had been introduced a couple of years prior for the DK machine gun. Tula designer S.V. Vladimirov answered the call by producing basically an enlarged version of the ShKAS, with a 1246 mm long barrel and a total length of 1726 mm. The first prototype was ready for trials on May 28, 1932. The testing pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berezin B-20
The Berezin B-20 (Березин Б-20) was a 20 mm caliber autocannon used by Soviet aircraft in World War II. Development The B-20 was created by Mikhail Yevgenyevich Berezin in 1944 by converting his 12.7 mm Berezin UB machine gun to use the 20 mm rounds used by the ShVAK cannon. No other changes were made to the weapon which was pneumatically or mechanically charged and was available in both synchronized and unsynchronized versions. In 1946, an electrically-fired version was created for the turrets of the Tupolev Tu-4 bomber until the Nudelman-Rikhter NR-23 cannon became available. The B-20 was a welcome replacement for the ShVAK because it was significantly lighter - 25 kg (55 lb) to the 40 kg (80 lb) ShVAK - without sacrificing rate of fire or muzzle velocity. Specifications * Ammunition: 20×99mm * Empty weight: 25 kg (55 lbs) * Muzzle velocity: 750–770 m/s (2,460-2,525 ft/s) * Rate of fire: 800 rounds/min (600 synchr ...

Berezin UB
The Berezin UB () (''Berezin's Universal'') was a 12.7 mm caliber Soviet aircraft machine gun widely used during World War II. Development In 1937, began designing a new large-caliber aircraft machine gun chambered to the 12.7 mm round used by infantry machine guns. The new design passed factory trials in 1938 and was accepted into service in 1939 under the designation BS (Березин Синхронный, Berezin Sinkhronniy, Berezin Synchronized). The rate of fire made it well suited for use as defensive armament in aircraft. While a successful design, BS was not without its faults, the biggest being its cable-operated charging which required considerable physical strength. Continued development resulted in the improved UB which came in three versions: UBK (Крыльевой, Krylyevoi, for the wings), UBS (Синхронный, Sinkhronniy, Synchronized), and UBT (Турельный, Turelniy, for the turret), with UBS and UBK charged by compressed air. The UB w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MK 108 Cannon
The MK 108 (German: ''Maschinenkanone''—"machine cannon") is a 30 mm caliber autocannon manufactured in Germany during World War II by Rheinmetall‑Borsig for use in aircraft. Development The weapon was developed as a private venture by the company in 1940 and was submitted to the '' Reichsluftfahrtministerium'' (RLM—Reich Aviation Ministry) in response to a 1942 requirement for a heavy aircraft weapon for use against the Allied heavy bombers appearing over German-controlled regions by then. Testing verified that the autocannon was well suited to this role, requiring on average just four hits with its 85g RDX-load (in a 330g shell) and a resulting strongly brisant high-explosive ammunition, to bring down a heavy bomber such as a B-17 Flying Fortress or B-24 Liberator, and just a single "shattering" hit to down a fighter. In comparison, the otherwise excellent 20 mm MG 151/20 (18g of HE in a 92g shell) required about 15 to 20 hits to down a B-17. The MK 108 was quick ...

MK 103 Cannon
The Rheinmetall-Borsig MK 103 ("MK" - '' Maschinenkanone'') was a German 30 mm caliber autocannon that was mounted in German combat aircraft during World War II World War II or the Second World War (1 September 1939 – 2 September 1945) was a World war, global conflict between two coalitions: the Allies of World War II, Allies and the Axis powers. World War II by country, Nearly all of the wo .... Intended to be a dual purpose weapon for anti-tank and air-to-air fighting, it was developed from the MK 101. Compared to the MK 101 it was faster firing, and was originally intended to develop a higher muzzle velocity than the MK 101. Unlike the MK 101, the MK 103 used a belt feed, allowing it to potentially carry a larger ammunition load. The MK 103 used electrically primed rather than percussion-primed ammunition. The operating mechanism differed from the recoil-operated MK 101 in that it used a combination of gas and recoil operation. After firing, gas pressure served ...
