Military Helicopters
A military helicopter is a helicopter that is either specifically designed for or converted for usage by a military. A military helicopter's mission is a function of its design or conversion. The most common use of military helicopters is airlift, but transport helicopters can be modified or converted to perform other missions such as combat search and rescue (CSAR), medical evacuation (MEDEVAC), serving as an airborne command post, or even armed with weapons for close air support. Specialized military helicopters are intended to conduct specific missions. Examples of specialized military helicopters are attack helicopters, observation helicopters and anti-submarine warfare (ASW) helicopters. Types and roles Military helicopters play an integral part in the sea, land and air operations of modern militaries. Generally manufacturers will develop airframes in different weight/size classes which can be adapted to different roles through the installation of mission specific equipment ...

Nose-mounted sensors help target acquisition, acquire targets and provide night vision device, night vision. It carries a 30 mm caliber, M230 chain gun under its forward fuselage and four hardpoints on stub-wing pylons for armament and stores, typically AGM-114 Hellfire missiles and Hydra 70 rocket pods. redundancy (engineering), Redundant systems help it survive combat damage. The Apache began as the ''Model 77'' developed by Hughes Helicopters for the United States Army's Advanced Attack Helicopter program to replace the Bell AH-1 Cobra, AH-1 Cobra. The prototype YAH-64 first flew on 30 September 1975. The U.S. Army selected the YAH-64 over the Bell YAH-63 in 1976, and later approved full production in 1982. After acquiring Hughes Helicopters in 1984, McDonnell Douglas continued AH-64 production and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Attack Helicopter
An attack helicopter is an armed helicopter with the primary role of an attack aircraft, with the offensive (military), offensive capability of engaging ground targets such as enemy infantry, military vehicles and fortifications. Due to their heavy armament they are sometimes called helicopter gunships. Attack helicopters can use weapons including autocannons, machine guns, rocket (weapon), rockets, and anti-tank missiles such as the AGM-114 Hellfire. Some attack helicopters are also capable of carrying air-to-air missiles, though mostly for purposes of self-defense against other helicopters and low-flying light combat aircraft. A modern attack helicopter has two primary roles: first, to provide direct fire, direct and accurate close air support for ground troops; and second, the anti-tank weapon#Helicopter, anti-tank role to destroy grouped enemy armored fighting vehicle, armored vehicles. Attack helicopters are also used as escort fighter, protective escort for transport h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PLAAF Changhe WZ-10 - Jordan
The People's Liberation Army Air Force, also referred to as the Chinese Air Force () or the People's Air Force (), is the primary aerial warfare service of the People's Liberation Army. The PLAAF controls most of the PLA's air assets, including tactical aircraft, large airlifters, and strategic bombers. It includes ground-based air defense assets, including national early-warning radars, and controls the Airborne Corps. The PLAAF traces its origins to the establishment of a small aviation unit by the Chinese Communist Party (CCP) in 1924, during the early years of the Republic of China. This initial group comprised nine cadets who trained under the Guangzhou Revolutionary Government Aviation Bureau, with further advanced training in the Soviet Union. Despite initial resource constraints, including a lack of aircraft and airfields, the CCP's Central Military Commission (CMC) established foundational aviation schools and, by the end of World War II, had begun significant organi ...

Group Army
Group armies () or army groups or combined corps, are corps-level military formations of the People's Liberation Army Ground Force of China. Despite what the name suggests, current Group Armies are not army-level formations, but corps-sized formations commanding 12 to 14 brigades, roughly equivalent to United States Army Corps. Some may use or translate 'Group Army' loosely to mean the same as Army Group through various time periods of history, depending on whether the military formation is under Nationalist China (ROC) or Communist China (PRC). Chinese Army Group or Group Army used to be equivalent to field army or army group in other militaries due to translation issues and ambiguity of the Chinese language. This is because while" " in Chinese means "corps" when classifying by size or number of troops, it also means (and more frequently so) in common and less precise military usage – any significant grouping of combat troops, such as army, Army group, or even entire mil ...

Retrofit
Retrofitting is the addition of new technology or features to older systems. Retrofits can happen for a number of reasons, for example with big capital expenditures like naval vessels, military equipment or manufacturing plants, businesses or governments may retrofit in order to reduce the need to replace a system entirely. Other retrofits may be due to changing codes or requirements, such as seismic retrofit which are designed strengthening older buildings in order to make them earthquake resistant. Retrofitting is also an important part of climate change mitigation and climate change adaptation: because society invested in built infrastructure, housing and other systems before the magnitude of Effects of climate change">changes anticipated by climate change. Retrofits to increase building efficiency, for example, both help reduce the overall negative impacts of climate change by reducing building emissions and environmental impacts while also allowing the building to be more ...

Mil Mi-17
The Mil Mi-17 (NATO reporting name: Hip) is a Soviet-designed Russian military helicopter family introduced in 1975 (Mi-8M), continuing in production at two factories in Russia, in Kazan and Ulan-Ude. It is known as the Mi-8M series in Russian service. The helicopter is mostly used as a medium twin-turbine transport helicopter, as well as an armed gunship version. Development Developed from the basic Mi-8 airframe, the Mi-17 was fitted with the larger Klimov TV3-117MT engines, rotors, and transmission developed for the Mi-14, along with fuselage improvements for heavier loads. Optional engines for " hot and high" conditions are the Isotov TV3-117VM. Recent exports to China and Venezuela for use in high mountains have the new Klimov VK-2500 version of the Klimov TV3-117 engine with FADEC control. The designation Mi-17 is for export; the Russian armed forces call it the Mi-8MT. The Mi-17 is recognisable by the tail rotor on the port side instead of the starboard side, a ...

Identification Friend Or Foe
Identification, friend or foe (IFF) is a combat identification system designed for command and control. It uses a transponder that listens for an ''interrogation'' signal and then sends a ''response'' that identifies the broadcaster. IFF systems usually use radar frequencies, but other electromagnetic frequencies, radio or infrared, may be used. It enables military and civilian air traffic control interrogation systems to identify aircraft, vehicles or forces as friendly, as opposed to neutral or hostile, and to determine their bearing and range from the interrogator. IFF is used by both military and civilian aircraft. IFF was first developed during World War II, with the arrival of radar, and several friendly fire incidents. IFF can only positively identify friendly aircraft or other forces. If an IFF interrogation receives no reply or an invalid reply, the object is not positively identified as foe; friendly forces may not properly reply to IFF for various reasons such as e ...

Electronic Countermeasures
An electronic countermeasure (ECM) is an electrical or electronic device designed to countermeasure, trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of Radar jamming, jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile guidance, missile terminal homers. History The first example of electronic countermeasures being a ...

Avionics
Avionics (a portmanteau of ''aviation'' and ''electronics'') are the Electronics, electronic systems used on aircraft. Avionic systems include communications, Air navigation, navigation, the display and management of multiple systems, and the hundreds of systems that are fitted to aircraft to perform individual functions. These can be as simple as a searchlight for a police helicopter or as complicated as the tactical system for an airborne early warning platform. History The term "avionics" was coined in 1949 by Philip J. Klass, senior editor at ''Aviation Week & Space Technology'' magazine as a portmanteau of "aviation electronics". Radio communication was first used in aircraft just prior to World War I. The first Airborne radio relay, airborne radios were in zeppelins, but the military sparked development of light radio sets that could be carried by heavier-than-air craft, so that aerial reconnaissance biplanes could report their observations immediately in case they we ...

UH-60 Black Hawk
The Sikorsky UH-60 Black Hawk is a four-blade, twin-engine, medium-lift military utility helicopter manufactured by Sikorsky Aircraft. Sikorsky submitted a design for the United States Army's Utility Tactical Transport Aircraft System (UTTAS) competition in 1972. The Army designated the prototype as the ''YUH-60A'' and selected the Black Hawk as the winner of the program in 1976, after a fly-off competition with the Boeing Vertol YUH-61. Named after the Native American war leader Black Hawk (Sauk leader), Black Hawk, the UH-60A entered service with the U.S. Army in 1979, to replace the Bell UH-1 Iroquois as the Army's tactical transport helicopter. This was followed by the fielding of electronic warfare and special operations variants of the Black Hawk. Improved UH-60L and UH-60M utility variants have also been developed. Major variants include the United States Navy, Navy's Sikorsky SH-60 Seahawk, SH-60 Seahawk, the United States Air Force, Air Force's Sikorsky HH-60 Pave Ha ...
