AH64_Apache_-_RIAT_2010_(4815997467)

The Boeing (McDonnell Douglas) (formerly Hughes) AH-64A Apache is the Army’s primary attack helicopter. It is a quick-reacting, airborne weapon system that can fight close and deep to destroy, disrupt, or delay enemy forces. The Apache is designed to fight and survive during the day, night, and in adverse weather throughout the world. The principal mission of the Apache is the destruction of high-value targets with the HELLFIRE missile. It is also capable of employing a 30MM M230 chain gun and Hydra 70 (2.75 inch) rockets that are lethal against a wide variety of targets. The Apache has a full range of aircraft survivability equipment and has the ability to withstand hits from rounds up to 23MM in critical areas.

The AH-64 Apache is a twin-engine, four bladed, multi-mission attack helicopter designed as a highly stable aerial weapons-delivery platform. It is designed to fight and survive during the day, night, and in adverse weather throughout the world. With a tandem-seated crew consisting of the pilot, located in the rear cockpit position and the co-pilot gunner (CPG), located in the front position, the Apache is self-deployable, highly survivable and delivers a lethal array of battlefield armaments. The Apache features a Target Acquisition Designation Sight (TADS) and a Pilot Night Vision Sensor (PNVS) which enables the crew to navigate and conduct precision attacks in day, night and adverse weather conditions.

An on-board video recorder has the capability of recording up to 72 minutes of either the pilot or CPG selected video. It is an invaluable tool for damage assessment and reconnaissance. The Apache’s navigation equipment consists of a doppler navigation system, and most aircraft are equipped with a GPS receiver.

The Apache has state of the art optics that provide the capability to select from three different target acquisition sensors. These sensors are:

– Day TV. Views images during day and low light levels, black and white.
– TADS FLIR. Views thermal images, real world and magnified, during day, night and adverse weather.
– DVO. Views real world, full color, and magnified images during daylight and dusk conditions.

The Apache has four articulating weapons pylons, two on either side of the aircraft, on which weapons or external fuel tanks can be mounted. The aircraft has a LRF/D. This is used to designate for the Hellfire missile system as well as provide range to target information for the fire control computer’s calculations of ballistic solutions.

LONGBOW FCR

The LONGBOW FCR has a very low probability of intercept. It rapidly and automatically searches, detects, locates, classifies, and prioritizes multiple moving and stationary targets on land, water and in the air in all weather and battlefield conditions from standoff ranges. Target coordinates are automatically available to other sensors and weapons for target confirmation, rapid engagement, and reduced fratricide. Target data is digitally available through the data modem for real-time transfer to other platforms and command posts. The self-contained Radar Frequency Interferometer provides rapid and accurate identification and azimuth to enemy air defense units. High system reliability and two-level maintenance maximize operational availability and reduce support costs. @ockheedmartin.com

apache01mA British Army WAH-64 'Apache' attack helicopter fires a salvo of CRV7 (Practise) rockets at targets down range. Army Air Corps Apache pilots from 651 (AHF) Squadron based in Middle Wallop, Hampshire attended a two-day live firing exercise at Lulworth Ranges/Bovington Camp in Dorset. The aim of the exercise was to qualify the pilots as instructors so they can teach future pilots in core Apache skills.

The Apache fully exploits the vertical dimension of the battlefield. Aggressive terrain flight techniques allow the commander to rapidly place the ATKHB at the decisive place at the optimum time. Typically, the area of operations for Apache is the entire corps or divisional sector. Attack helicopters move across the battlefield at speeds in excess of 3 kilometers per minute. Typical planning airspeeds are 100 to 120 knots during daylight and 80 to 100 knots at night. Speeds during marginal weather are reduced commensurate with prevailing conditions. The Apache can attack targets up to 150 km across the FLOT. If greater depth is required, the addition of ERFS tanks can further extend the AH-64’s range with a corresponding reduction in Hellfire missile carrying capacity (four fewer Hellfire missiles for each ERFS tank installed).

FIM-92A Stinger Weapons System

atas_resize

The Stinger system consists of a Stinger round encased in its launch tube and a separate gripstock assembly.

The “fire-and-forget” Stinger missile employs a passive infrared seeker to home in on its airborne target. A passive infrared seeker emits no radiation that a target aircraft can detect, and, instead, guides on the infrared energy (heat) emitted by the target. Because the Stinger employs a passive homing seeker, it is a “fire-and-forget” weapon that needs no guidance from the operator after firing, unlike other missiles that track the reflection of a designator beam, requiring the operator to maintain a lock on the target. This allows a Stinger operator to take cover, relocate, or engage other targets immediately after firing a Stinger.

The Stinger system features a proportional navigation system, integrated Indentification Friend or Foe (IFF) interrogation, and threat adaptive guidance. Proportional navigation enables the missile to effectively hit moving targets by injecting a multiplier factor into course corrections so that the missile overcorrects for a target’s evasive maneuvers, leading the target to a successful interception. The integrated IFF subsystem allows the Stinger operator to query a target aircraft to determine if it is friendly. Before firing, the operator depresses a button on the gripstock assembly, emitting a coded radio signal. Aircraft equipped with friendly IFF systems will recognize the coded signal and respond with the appropriate coded reply. The IFF subsystem emits one tone if it authenticates a friendly aircraft, and another if the aircraft is unknown. The IFF subsystem is intended to prevent friendly-fire incidents. The Stinger’s threat adaptive guidance takesover in the final stages of its approach to the target, slightly shifting the missile’s aim from the target’s IR hotspot to more vulnerable areas of the aircraft.

The Air-to-Air Stinger [ATAS] is an adaption of the man portable Stinger System. It is a light weight missile designed to engage low altitude targets.

Note Armor compared to Russian Mi-28 and Ka-52:

From the book of A. Mazepov, A. Mihkaev, V. Zenkin, A Zhirnov and A. Fomin about the Ka-50 called Polygon from 1996, on Page 31, there is said how the Armor was made on Ka-50 and after that also installed on Mi-28.
It is  a 3 hardlinered armor, the inner cockpit section made of a full single titanium alloy “bathtub” covering both pilots, followed by a middle liner of ceramic plates, which caused trouble first after a single shot they break apart and lost all its protective abilities, they avoided that by covering this ceramic plates with kevlar/aramid that was glued on tightend and the outer liner which gives the aerodynamic shape and is made of alluminium alloy with a part carbon in it. The total armor per pilot for russian Ka-50 which they could use was about 300kg while the Apache uses about 90kg of armor per pilot. The Mi-28 has about 250-280kg which was mentioned somewhere else. The Ka-52 has less armor than both Mi-28 and Ka-50 spend for each pilot but it is still in the figure of 150-200kg. (Source:Russian Defense)
