HESA Shahed 285
HESA Shahed 285 ( fa, شاهد ۲۸۵) is a light attack/reconnaissance helicopter developed in Iran. It was unveiled on . It is being produced in two versions: a light attack/recon version and a maritime patrol/anti-ship version. Design and development The Shahed 285 is based on the composite ''Shahed-278'', which is a relatively light helicopter with empty weight, derived from the Bell 206 Jetranger. Compared to the American OH-58 Kiowa that retains the airframe of the Bell 206, the Shahed 285 is a single-seater with a narrower fuselage, but retains the tail and powerplant / rotor structures, and is intended for military use. Although designed by the IRGC, this helicopter is scheduled to be produced by HESA. Shahed 285 comes in two variants. AH-85A which is a land based variant and AH-85C which is a naval one. AH-85A is armed with 14 rockets and a PKMT light machine gun either on a rotatable turret or on a static mount, or an NSV heavy machine gun in an underfuselage go ...

Anti-ship Missile
An anti-ship missile (AShM) is a guided missile that is designed for use against ships and large boats. Most anti-ship missiles are of the sea skimming variety, and many use a combination of inertial guidance and active radar homing. A good number of other anti-ship missiles use infrared homing to follow the heat that is emitted by a ship; it is also possible for anti-ship missiles to be guided by radio command all the way. The first anti-ship missiles, which were developed and built by Nazi Germany, used radio command guidance.https://airandspace.si.edu/collection-objects/bomb-guided-fritz-x-x-1/nasm_A19840794000#:~:text=The%20Fritz%20X%2C%20also%20known,the%20Henschel%20Hs%20293%20missile. These saw some success in the Mediterranean Theatre during 1943–44, sinking or heavily damaging at least 31 ships with the Henschel Hs 293 and more than seven with the ''Fritz X'', including the Italian battleship ''Roma'' and the light cruiser .

2000s Iranian Military Utility Aircraft
S, or s, is the nineteenth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''ess'' (pronounced ), plural ''esses''. History Origin Northwest Semitic šîn represented a voiceless postalveolar fricative (as in 'ip'). It originated most likely as a pictogram of a tooth () and represented the phoneme via the acrophonic principle. Ancient Greek did not have a phoneme, so the derived Greek letter sigma () came to represent the voiceless alveolar sibilant . While the letter shape Σ continues Phoenician ''šîn'', its name ''sigma'' is taken from the letter ''samekh'', while the shape and position of ''samekh'' but name of ''šîn'' is continued in the '' xi''. Within Greek, the name of ''sigma'' was influenced by its association with the Greek word (earlier ) "to hiss". The original name of the letter "sigma" may have been ''san'', but due to the complica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IAR 317 Airfox
The IAR 316 is a Romanian license-built Aérospatiale SA 316B Alouette III manufactured by Industria Aeronautică Română (IAR). Design and development IAR 316 IAR began manufacturing the IAR 316 in 1971 at its plant near Brașov, Romania. Production ended in 1987. 250 units were built, 125 of those were built for the Military of Romania, which still uses it to this day in a training capacity. Some IAR 316s were operated in the civilian role in Romania and others were exported to various nations, including Pakistan, Angola, and Guinea. The IAR 316 was modified to carry weapons more common in the Eastern-bloc, such as 57mm rocket pods, 7.62mm machine guns, and anti-tank missiles. An early example was exhibited at the Paris Air Show in June 1973. IAR 317 The IAR 317 Airfox was an attempt by IAR to make an attack helicopter out of the IAR 316.

Atlas XH-1 Alpha
The Atlas XH-1 Alpha is a prototype attack helicopter built by Atlas Aviation (now Denel) of South Africa, which used it as a concept demonstrator for the then-planned Rooivalk project. Development It was developed from an Aérospatiale Alouette III airframe, retaining that helicopter's engine and dynamic components, but replacing the original cockpit with a stepped tandem one, adding a 20 mm cannon under the chin and converting the undercarriage to tail-dragger configuration. The XH-1 first flew on 3 February 1985,''Air International'' June 1986, p. 599. and soon embarked on a rigorous flight test program to examine the feasibility of a dedicated attack helicopter in southern African conditions. The results were ultimately good enough to convince Atlas and the South African Air Force to go ahead with the development of a dedicated attack helicopter, the Denel Rooivalk. The XH-1 and Rooivalk are completely different aircraft and share no components. The Rooivalk was deve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NSV Machine Gun
The NSV (Russian НСВ Никитина-Соколова-Волкова), also known as the «Utyos» (Project: ''Lonely Cliff''), is a 12.7mm caliber heavy machine gun of Soviet origin, named after the designers, G. I. Nikitin (Г. И. Никитин), Y. S. Sokolov (Ю. М. Соколов) and V. I. Volkov (В. И. Волков). It was designed to replace the DShK machine gun and was adopted by the Soviet Army in 1971. It is no longer being produced in Russia; the manufacturing license for the NSV ended up in Kazakhstan after the break-up of the Soviet Union. The NSV has been manufactured in Bulgaria, India, Poland and Yugoslavia under license.

Turboshaft
A turboshaft engine is a form of gas turbine that is optimized to produce shaftpower rather than jet thrust. In concept, turboshaft engines are very similar to turbojets, with additional turbine expansion to extract heat energy from the exhaust and convert it into output shaft power. They are even more similar to turboprops, with only minor differences, and a single engine is often sold in both forms. Turboshaft engines are commonly used in applications that require a sustained high power output, high reliability, small size, and light weight. These include helicopters, auxiliary power units, boats and ships, tanks, hovercraft, and stationary equipment. Overview A turboshaft engine may be made up of two major parts assemblies: the 'gas generator' and the 'power section'. The gas generator consists of the compressor, combustion chambers with ignitors and fuel nozzles, and one or more stages of turbine. The power section consists of additional stages of turbines, a gear reduction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolls-Royce Model 250-C20J
The Allison Model 250, now known as the Rolls-Royce M250, (US military designations T63 and T703) is a highly successful turboshaft engine family, originally developed by the Allison Engine Company in the early 1960s. The Model 250 has been produced by Rolls-Royce since it acquired Allison in 1995. Development In 1958, the Detroit Diesel Allison division of General Motors was chosen by the US Army to develop a new light turbine engine to power a "Light Observation Aircraft" (LOA), to replace the Cessna O-1A Bird Dog. At this stage the US Army was unsure whether to have a fixed- or rotary-wing aircraft, so Allison was instructed to consider both applications. Design studies undertaken considered a wide range of possible mechanical configurations for the turboprop/turboshaft. These studies culminated in the testing of the first prototype engine, designated YT63-A-3, in April 1959. In 1960, the US Army settled for a rotary wing platform. The YT63-A-3 first flew in a variant of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multi-function Display
A multifunction display (MFD) is a small-screen ( CRT or LCD) surrounded by multiple soft keys (configurable buttons) that can be used to display information to the user in numerous configurable ways. MFDs originated in aviation, first in military aircraft, and later were adopted by commercial aircraft, general aviation, automotive use, and shipboard use. MFDs in aviation Often, an MFD will be used in concert with a primary flight display (PFD), and forms a component of a glass cockpit. MFDs are part of the digital era of modern planes or helicopter. The first MFDs were introduced by air forces in the late 1960s and early 1970s; an early example is the F-111D (first ordered in 1967, delivered from 1970–73). The advantage of an MFD over analog display is that an MFD does not consume much space in the cockpit, as data can be presented in multiple pages, rather than always being present at once. For example, the cockpit of RAH-66 "Comanche" does not have analog dials or gau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
