Grigorovich I-Z
The Grigorovich I-Z was a fighter aircraft developed in the Soviet Union during the 1930s. Advances in aircraft survivability thanks to all-metal construction and self-sealing and inert gas-filled fuel tanks led to experimentation with large-caliber weapons to shoot them down. In Soviet Union, Leonid Kurchevsky developed a series of recoilless rifles in various calibers and in 1930 was decided to adapt the 76.2 mm (3 in) weapons for aircraft use. The result was a conventional strut-braced monoplane with fixed landing gear. A pair of Kurchevsky APK (APK - ''Aviatsionnaya Pushka Kurchevsky'' - aircraft cannon Kurchevsky) rifles were mounted under the wings outside the propeller arc and the rear fuselage and tail assembly were of reinforced metal construction to withstand the blast. A single small-caliber synchronized machine gun in the left fuselage was added to aid the pilot in aiming. Two prototypes were built, the first flying in mid-1931. The second strengthened I-Zb ...

Parasite Fighter
A parasite aircraft is a component of a composite aircraft which is carried aloft and air launched by a larger carrier aircraft or mother ship to support the primary mission of the carrier. The carrier craft may or may not be able to later recover the parasite during flight. The first parasite aircraft flew in 1916, when the British launched a Bristol Scout from a Felixstowe Porte Baby flying boat. The idea eventually developed into jet bombers carrying fully capable parasite fighters. With the advent of long-range fighters equipped with air-to-air missiles, and aerial refueling, parasite fighters fell out of use. Parasite fighters Until the middle of the 20th century there was military interest in parasite fighters – fighter aircraft intended to be carried into a combat zone by a larger aircraft, such as a bomber. If the bomber were threatened, the parasite would be released to defend it. Parasite fighters have never been highly successful and have seldom been used in com ...

1930s Soviet Fighter Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Tupolev I-12
The Tupolev I-12 (also known as the ANT-23) was a prototype Soviet fighter aircraft that never reached production. The I-12 was of unconventional design with twin booms made of water pipes containing recoilless rifles and two engines in a push-pull configuration. The aircraft first flew in 1931 but did not enter production due to disappointing performance and operational difficulties such as the inability for the pilot to escape the aircraft without hitting the propeller arc behind him. The second prototype from Tupolev (designated ANT-23bis) was never completed. Specifications References External linksAirwar (in Russian) {{Soviet fighter designations 1930s Soviet fighter aircraft |
PV-1 Machine Gun
PV-1 (''Pulemet Vozdushny'', airborne machine gun) is a Soviet air-cooled version of the Russian M1910 Maxim for mounting on aircraft. It was designed between 1926 and 1927. The first prototypes were produced and accepted into service in 1928.Широкорад А.Б. (2001) ''История авиационного вооружения'' Харвест (Shirokorad A.B. (2001) ''Istorya aviatsionnogo vooruzhenia'' Harvest. ) (''History of aircraft armament''), pages 68-69 The gun was created at the initiative of the Soviet military pilot Alexander Vasilevich Nadashkevich (Александр Васильевич Надашкевич) after he was appointed to the Scientific and Technical Committee of the Soviet Air Force in 1923. His main objective was to obtain a gun with increased rate of fire and reduced weight relative to the M1910. In this endeavor, Nadashkevich collaborated with several engineers from the Tula Arms Factory, including Tretyakov and Pastuhov, who were the spiri ...

Shvetsov M-22
The Bristol Jupiter was a British nine-cylinder single-row piston radial engine built by the Bristol Aeroplane Company. Originally designed late in World War I and known as the Cosmos Jupiter, a lengthy series of upgrades and developments turned it into one of the finest engines of its era. The Jupiter was widely used on many aircraft designs during the 1920s and 1930s. Thousands of Jupiters of all versions were produced, both by Bristol and abroad under licence. A turbo-supercharged version of the Jupiter known as the Orion suffered development problems and only a small number were produced. The "Orion" name was later re-used by Bristol for an unrelated turboprop engine. Design and development The Jupiter was designed during World War I by Roy Fedden of Brazil Straker and later Cosmos Engineering. The first Jupiter was completed by Brazil Straker in 1918 and featured three carburettors, each one feeding three of the engine's nine cylinders via a spiral deflector housed in ...

Zveno Project
Zveno (Russian: Звено, a military unit "Flight") was a parasite aircraft developed in the Soviet Union during the 1930s. It consisted of a Tupolev TB-1 or a Tupolev TB-3 heavy bomber mothership and two to five fighters. Depending on the variant, the fighters either launched with the mothership or docked in flight, and they could refuel from the bomber. The definitive Zveno-SPB using a TB-3 and two Polikarpov I-16s, each armed with two bombs, was used operationally as a strategic weapon system with good results against targets in Romania during the opening stages of the German-Soviet War. The same squadron later carried out an attack against a bridge on the River Dnieper that had been captured by German forces. Development In June 1931, Vladimir Vakhmistrov of the NII VVS (''Nauchno-Issledovatel'skiy Institut Voyenno-Vozdushnykh Sil'' – scientific test institute of the air force) started work on combinations of fighters rigidly attached to heavy bomber aircraft.

Monoplane
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

Recoilless Rifle
A recoilless rifle, recoilless launcher or recoilless gun, sometimes abbreviated "RR" or "RCL" (for ReCoilLess) is a type of lightweight artillery system or man-portable launcher that is designed to eject some form of countermass such as propellant gas from the rear of the weapon at the moment of firing, creating forward thrust that counteracts most of the weapon's recoil. This allows for the elimination of much of the heavy and bulky recoil-counteracting equipment of a conventional cannon as well as a thinner-walled barrel, and thus the launch of a relatively large projectile from a platform that would not be capable of handling the weight or recoil of a conventional gun of the same size. Technically, only devices that use spin-stabilized projectiles fired from a rifled barrel are recoilless rifles, while smoothbore variants (which can be fin-stabilized or unstabilized) are recoilless guns. This distinction is often lost, and both are often called recoilless rifles. Though sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
