Shahed 285

The Shahed 285 is an Iranian lightweight armed scout helicopter. It was first publicly revealed in 2009. It is based on a modified airframe and components of the Bell 206 JetRanger. Compared to the American OH-58 Kiowa, which also retains the airframe of the Bell 206, the Shahed 285 is a single-seater with a narrower fuselage. The Shahed 285 is not able to carry the heavy anti-ship missiles Iran has. Most Iranian announcements of newly developed, high tech weapons are normally a photo op for a mock-up or a prototype. Production variants rarely arrive in meaningful numbers, if at all. While the clerics and politicians talk a tough game, they rarely do anything - talk loudly and carry a small stick.

The Shahed 285 is an LHX with Iranian characteristics. In the United States, the Comanche lightweight armed scout helicopter started in 1983 as the LHX [Light Helicopter, Experimental] program. The LHX would be a low-weight, low-maintenance, single pilot aircraft that would enter Aviation inventory in very large numbers. the LHX was supposed to fit into the lower portion of the highlow mix, produced in combination with the high end, heavier Apache. The requirement for a mixed scout/attack aircraft fully took advantage of the lessons learned in Vietnam (better survivability, target engagement capability, etc), and would replace not just the OH-58 and OH-6, but all utility, light attack, and scout aircraft in the inventory.

The rcle of the helicopter in military operations had been greatly expanded by the early 1980s. Helicopters wer to contribute enormously to the US Army's ability to conduct its land combat operations. The helicopter's newly adopted primary role as an antiarmor weapon system means that scout and attack helicopters must be able to fly and complete combat missions day and night in all kinds of weather. The scout and attack (SCAT) mission was a good example of what is expected for the Army's projected single-pilot helicopters of the future: the pilot would have to reconnoiter and contact enemy elements, hand-off targets to other scout/attack elements, help select firing positions, and engage enemy targets. The aircrew would have to do all these things under the stressful and fatiguing conditions of low-level or nap-of-the-earth (NOE) flight in all kinds of weather while avoiding obstacles and probably taking enemy fire.

Aside from psychological factors in combat, workload was considered the main determining factors for the selection of one versus two crew members aircraft for the LHX. Workload is generally at a steady level with changes of the level for various parts of the mission, with NOE and simultaneous weapons management being the most demanding. Generally, one pilot is sufficient for the workload especially if mission equipment package provides automatic navigational aids. The workload, on the other hand, exhibits peaks for brief periods. These are associated with target recording, enemy engagements, weapons set up and weapons delivery. It is during these peak workload periods that one may overload the single pilot or reduce effectiveness and survivability.

Older more experienced pilots tended to say that one-man missions were commonplace in the older vintage helicopters of the 1950-1965 era and that they were effective. Younger lesser experienced pilots, who "grew up" with two-man missions, post 1965, tended to say that two-man crews were essential for effectivenss. It appears that there are strong opinions on both sides of this issue. Some of the detailed sub-elements of the major Mission Equipment Package categories were to facilitate single pilot operation.

A single pilot would be subjected to extremely high workloads. In some cases, eg, night and adverse weather, workloads may exceed the capabilities of the best pilots. Analyses indicated that successful mission accomplishment by a single pilot was highly problematical especially under adverse weather, at night, and under degraded equipment conditions. Reviewrs were doubtful that the technology for a single pilot helicopter was available, and management soon took action to cancel the one-seat LHX design.

The Shahed 285 was unveiled Sunday May 24, 2009 on the anniversary of the 1982 liberation of the Iranian city Khoramshahr -- which was occupied by Iraqi forces during the 1980-88 war. A number of Shahed 285s -- which have successfully passed numerous test-flights -- were handed to the IRGC Air Force. The IRGC says the state-of-the-art helicopter is capable of taking part in seaborne and airborne combat operations. The Shahed 285 can carry autocanons, machine guns, guided missiles, anti-armor missiles and air-to-air and air-to-sea missiles.

The "100-percent domestic-made all-weather aircraft" has a slick aerodynamic design and is capable of taking off in harsh conditions. The chopper's rotors and cabin were said to be made from advanced composite materials. The newly developed aircraft is easy-to-maintain and can be stored in combat zones for immediate access.

Iran's latest endeavor follows the successful test-fire of its new deterrent ballistic missile, the Sejjil II, which has a 2000-kilometer surface-to-surface range. Over the years after the 1979 Islamic Revolution, internationally blockaded Iran has managed to design and manufacture various missiles, fighters, stealth aircraft, drones, submarines, radar systems, and military vessels.

Deputy Commander of the Iranian Army's Ground Forces Brigadier General Kiomars Heidari said the Cobra Melli (National Cobra) helicopter gunship will be deployed for the first time in a specialized military drill by the Armys airborne units in the near future, Fars News Agency reported Wednesday May 23, 2012. The commander did not offer a specific date for the drill but described it as a showcase of military self-sufficiency in the field of helicopters.

In the past, the armys airborne units were hugely dependent on countries that built helicopters but thanks to efforts by Iranian experts of the Ground Forces, such dependency has entirely been done away with, said Gen. Heidari. We now depend on native forces to conduct all repair and maintenance work on our helicopter fleets. He also emphasized that all the design and development process for building the helicopter gunship has been carried out in the country, adding that in some respects its capabilities are superior to the US-built Apache helicopters.

He reiterated that in the upcoming army drill, indigenous military helicopters will be armed with a variety of domestically-manufactured precision arms and missiles. Heidari stated as well that a number of advanced anti-helicopter and anti-armor weaponry would also be examined in the upcoming drill.

Compared to the American OH-58 Kiowa which 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. The helicopters of the type perform military missions, including reconnaissance and combat patrol and support ground forces is developed.

These missions are suitable for support of ground forces, attacking enemy positions, conducting fire on them, destroy enemy positions and attacking medium and heavy equipment (tanks, personnel carriers, etc.) in order to reduce the pressure on the friendly forces work.

Shahed 285 is a helicopter design in the category helicopters to run better missions. The helicopter has a range of 800 km and an endurance of about 5 hours is desirable, it is possible that it will remain in the sky without the need for refueling frequently return possible.

Extensive use of non-metallic composite materials, in addition to weight loss and reduced energy absorption bird radar, bring other benefits. Bird weight loss due to the use of composite materials that are lighter than metals, increased cargo weight portable bird as well. The position of carrying arms, one on each side of the body, each seven rocket launchers to install one or two 2.75 inch. Also on the roof there is a system of electro-optical or thermal means and the ability to install and detachment has been observed. A naval version has been developed which have many similarities with the land version.

The camouflage color is light blue for marine environments in this instance, employed and so far there have been two types of missile weapons on it. Anti-ship missiles known as "Kosar" weighing 120 kg and a range of about 25 kilometers (who Asrshlyk of helicopter, also will increase) the aircraft is installed on each side of the helicopter.

Rockets also called "SADID 1" at the seat of the helicopter-mounted four on each side, and according to sources, has a range of 10 km and the possibility of applying the laser-guided missile at the helicopter samples there. The missile weapons tested on the bird are not only of the kind listed.

The 278 and 285 helicopters have many similarities between the two types. In fact, major differences of size, length and diameter of one meter longer than the size of marine propellers tail to 6 cm. There is an increase operational readiness of relevant units as well as helicopter in the lead.

According to appearance, the tail section of the main body 278 and 285 are similar in control and two helicopters, according to data released by engine power and maximum takeoff weight of the two helicopters, a rule engine and transmission system be common to the most important component of every helicopter. The cabin has a lot in common system and the multifunction display (MFD) is used in the helicopter.
