    Unmanned aircraft

    http://hi-tech-products.blogspot.com/



     UAVs are aircraft with remote self-leadership. They carry on board cameras and sensors, communications equipment, and finally sophisticated weapons, and other cargo. Increasingly important role in military operations. Besides removing the losses suffered by combatants in during the tasks with high risk, such as the suppression of defense, can these aircraft lightweight to believe a poll tactically even the smallest combat unit on the ground, and also provide the Permanent Observer (in category heavier) for a period longer than you can bear Human crews effectively.First timeUsed drones for the first time applied in the Vietnam War. The U.S. Air Force launched from aircraft transport (Hercules) Firebees vehicles originally used as targets has been developed by Northrop Grumman (Northrop Grumman) to carry out the functions of imaging reconnaissance flights over North Vietnam. And the late seventies of the twentieth century, when it has become the surface guided missiles - a more effective atmosphere, developed unmanned aircraft lighter and less expensive to reduce casualties in the second poll. And since 1950 has undertaken these aircraft play an influential role in the fields of reconnaissance and surveillance and information gathering, and is expected in the Horn of atheist twenty more tasks include tasks combat specifically, especially as it brought about a clear shift in the wars of the beginning of this century, being made a significant development in the ability to work and continuity and the payment of accurate strikes, through the query and reconnaissance and surveillance zones Standing enemy, while difficult to execute these tasks by densely manned aircraft are at risk for sure.Currently covering unmanned aircraft (UAV) a wide range from large aircraft that derives its power from solar radiation and can stay in the air for days at an altitude of over 20,000 meters, to the small tools that soldiers can be transported in backpacks. And enjoy some drones capable of firing guided weapons from the air to the ground, while designed drones another to shatter suicide in radar antennas or armored vehicles.General features of the droneThere are two advantages essential characterized by the plane without a pilot compared to the plane inhabited: the first is that it falls completely ban the loss of the elements of human beings (crews aircraft), and the second is that they are better able to survive the podium to reduce fingerprints through the form of an optimal (it is impossible to design aircraft populated Traditional) Through the greatest ability to maneuver beyond human endurance capacity. Some of these aircraft on the one hand needs to recover in cases of network landing, and to support the launch rocket in cases of second hand. As for others and later depends technique suitable for take-off and landing from short distances without the use of modes in addition to assistance enjoy growing momentum permit to fly at high altitudes.The role of uninhabited aircraft to monitor the theater of operations

    Play drones role full of Amodiat and fixed-wing aircraft to monitor the theater of operations from the air, especially that later came to be developed for the development of other inhabited aircraft. Vlgaah the seventies of the last century was the pilots as having a high degree of security Proportional Avckaddoh with the rapid development of the actor to anti-air defense systems, which have become thoroughly enjoyed very high and far. Thus, modern technologies opened up in front of remotely piloted aircraft so that the increasing operational range and a steep rise in flight and accuracy in monitoring and detection. If the aircraft is equipped with suitable systems of radars, sensors and means of guidance, Pat could cover the fields and areas covered by the usually densely aircraft. Before the outbreak of war can work remotely and at high altitude to provide a survey of the area of ​​operations without provoke the enemy. At the outbreak of the war can maintain constant surveillance during which counts all the movements of the enemy and provide information about the accuracy of the aim of the injury fighter planes, missiles and other mobile. Thus allowing battlefield commanders on the ground to keep abreast of hostilities until the damage assessment phase.The key role of operational primary fighter aircraft without a pilot on the first day of the war, as entrusted with the task of suppression of air defenses hostile and silenced stroke preventive targeting air defense systems embedded within the enemy defenses, as part of the strike, the general orientation friendly forces to the enemy forces and positions before the start of the attack broad which is implemented by the joint units. Thus, this plane are an essential part of the rest of the system is working in full cooperation systems populated with systems to exploit the capabilities of command and control, communications, computer, query, surveillance and reconnaissance, or what is known as CIS4, so as to achieve the success of the military campaign and specific objectives.Capabilities of unmanned aircraftProven unmanned aircraft in the war in Afghanistan is pivotal in the central network operations. Has secured a continuous survey and payment information quick response sent to assets held communications and offensive to allow the exposure of targets to hit within five minutes of identification. On the other hand, also in Afghanistan, the unmanned aircraft video information directly not to hold ground, but also to support aircraft near «A - C - 130 Specter.Thus, due to a shift unmanned aircraft platforms and query survey and reconnaissance plane to multi-task, global air laboratory focused on the implementation of initiatives highlights the military advantage of the unique capabilities of this aircraft. These initiatives include the following:1 - to highlight the ability to distinguish the parties and friendly sites.2 - Show the ability to develop, computer reports regarding the status of the weather.3 - demonstrate the ability to reduce the anti-jamming receivers Data Global Positioning Systems (GPS), with the supply of these devices and navigation of media without the initial reception of the satellite.4 - front air control (FAC), which can be unmanned aircraft to perform three basic tasks - air insulation, close air support, search and rescue operations during the fighting - to the side of the track goals, education and / or illuminated.5 - Show the military value of integrating outstanding thermal unmanned aircraft to illuminate targets at night service attack aircraft used night-vision binoculars.6 - to highlight the interest of the military use of drones as relay contacts, arguments for the transfer of coded instructions on the tasks of air operations center directly to the cockpit of the plane, then migrate sham capabilities to combat damage to that center.Categories of UAVsThe growing interest in unmanned aircraft in order to perform an increasing number of roles, led to the development of a wide range of the aircraft and tested. I knew as well as discrimination and labels and categories.* Drones tactical;These aircraft are designed to support military commanders by providing the right information at the right time of the ranges of up to 200 km above enemy territory and its armed forces. The most important aircraft in this category:
    - Chricyril (Crecerelle) and Sbreuer (Sperwer) from Sagem (Sagem).- Phoenix (Phonex) from BAE Systems.
    - Pioneer (Pioneer).- Hunter (Hunter).* Aircraft stamina:Described the plane without a pilot's anti-satellite flying at low altitude to provide high-resolution images (Resolution) for query purposes.* Aircraft at medium altitude possibility:- Predator (Predator) (between 4600 m and 7700 m), which now develops Mi-Q -9 a Predator - b able to transfer loads to higher altitudes and more quickly.
    - Eagle 2 (Eagle 2) European (carrying 600 kg to a height of 14,000 feet for 24 hours).- Money system (Male) be extradited year 2009.- Global Hawk (Global Hawk), now known some development and improvement to lead U-2 missions plane U-2 but stronger possibility outweigh the possibility of U-2 four times. The complementary or even alternative for maritime patrol aircraft.- Predator - b (Predator-B) can in style implementation of maritime naval patrol mission for a period of 30 consecutive hours with a load weighing 640 kg.* Aircraft probability longevity:This type of aircraft is expected the first flight of its models in 2007. Energy will supply hydrogen fuel cells, and will be sold by 30 meters, and will operate at an altitude of 18,000 to 32,000 meters and carry monitoring equipment or communications will rule. And can be supplied with solar energy so that you can stay in the air from two weeks to six months, according to the supply line.* Aircraft vertical takeoff and landing:Direction tend to develop unmanned aircraft taking off and landing vertically for ground support operations and tactical missions emanating from on board the ships.
    * Drones fired manually:This type of aircraft (HLUAV) launched manually and used by members of a very promising sector for future development. Entrepreneurship and French companies in the development of this kind, as it intends to integrate the program Felin soldier expected to enter service by 2007-2008. It is expected that these aircraft have a miniature cameras Camera Day / Night and laser devices to set the goal and electronic devices and data connections.* Mirador (Mirador), length 52 cm which is a Belgian production.* V m d-3 (TMD-3) from Sagem, and a length of 2.1 m and can be disassembled and reassembled in a few minutes.* Rimanta (Remanta) French will enter service in 2010, and will be able to fly inside buildings, as it has a length of between 15 and 40 cm or less. DGA is working on a plane length of 04 cm and a range of one kilometer and can stay in the air, the maximum height of 100 m between 15 and 20 minutes, and with a weight of 1.5 kg. French company was able to produce other aircraft borne on the wings to provide custom arrays of solar energy.* Very small aircraft (Micro):Exploration palm-size aircraft will become a reality on the ground in the near future once solves some drawbacks such as the range and  Palace in the air. There are those who think explore planes bomb fired from the cannon Imagine everything in the course of its progress to be up to the end of the term it is on the ground and explode. Such systems will lead to the development of scary in the field of informatics and dynamic forces.- Pioneer (Pioneer) and weighs 4 kg and can be equipped with a thermal camera or visual.- Raven (Raven) and can stay in the air does not exceed 80 minutes and weighing 8 kg and size of half the size of the former Pioneer, so the soldier can carry.- Dragon (Dragon Eye) and 45 minutes flying over the ranges between 5 and 10 km.- Puma (Puma) and can fly between 2.5 and 3 hours.* Aircraft launches from the air:Aircraft could populated or non-populated to launch this type of aircraft is populated and smaller.- Silent (Silent Eye) from Raytheon (Raytheon) a plane 45 cm in length and can be launched from the Predator (Predator) for flying without a power source for 33 minutes. And can be equipped with electronic intelligence devices and sensors to detect chemicals and synthetic aperture radar (SAR) and laser radar.Another scenario longer serving with the launch of a winged rocket from Tomahawk to provide an estimate of the damage after the bombing.Models of UAVs
    These aircraft were used during the U.S. operations in Afghanistan and Iraq to expand the coverage area of ​​the aircraft fleet Gestarz (JStars). This aircraft flew for the first time in 1998 at high altitude for a long time (Hale).Turbine is equipped with a fan and one, and not the vehicle subtle as they are designed to operate in a manner remote monitoring of the environment, low to medium threat. And a length of 31.5 m and 35.4 m wing sold and extent of the back and forth of 25,000 km and steadfastness 36 hours at an altitude of 65,000 ft (19810 m), and useful load 910 kg. This plane can capture high-resolution images for large areas, and works in all weather conditions, day and night, as flying their own capabilities or under the control of land. It also can provide control over 24 hours in a beam diameter of 1200 nautical miles (2225 km). And currently enjoying carry sensors and weighing up to 900 kg. Some of these aircraft combines optical and electronic cameras cameras are infrared imaging hard (not video) and the radar's attention to detail, and so the effective range of more than 100 nautical miles (185 km).* Boeing X -45 (Boeing X-45):This aircraft flew for the first time in 2000 and conducted the first flight in May 2002, and will enter service in 2008. The length of this plane 39 feet and weight of the cargo full 2.45 kg. And a top speed during the flight to 0.85 Mac, and ceiling height of up to 4000 feet, the maximum range to 1,300 nautical miles. The arming phrase for multiple types of smart bombs. This feature plane disappear and the absence of guilt, and has sold a wingspan of 10.3 meters and a length of 8.08 meters and a height of 2.94 meters and full weight of 5528 kg and a range of 600 km. It is currently subject to a comprehensive development process under the name of x-45c, the first show of almost five meters and is intended to accommodate a load of approximately two tons, with the possibility of providing additional fuel tanks flying range to 2,400 kilometers. The flying devices as its set goals are the maximum reached by modern development. As we are talking about the possibility of providing fuel during flight, what drives the advantages to be closer to the traditional features fighter jets. Boeing intends to make them capable of carrying 8 small bombs (SDB) Each one weighs 113 kg and the possibility of fully loaded set JDAM bombs directed the GPS system. And the expansion of x-45c program also includes possible doing Bamyat of electronic warfare and climate control.* Predator (Predator):Is the only aircraft in the United States capable of providing instant video images in real-time day and night, in various weather conditions. Flew without a RQ-1PredatorA pilot for the first time in 1994. The of steadfastness period 40 hours maximum, and you can stay in connection with the station within the beam of 750 km per 24-hour period. And a length of 8.23 ​​meters and 14.84 meters wing sold, and beneficial DWT 200 kg electronic sensors include EO / IR and Video Mlontin and system works as infrared  forward (Flir) and the synthetic aperture radar SAR. And also has a compass data-satellite-based GPS. The flight altitude not exceed 25 thousand feet. And related ground station routing through a link the transfer of information ground, or through a link satellites are used when the aircraft is out of line of sight. Thanks to these connections do not require this plane, but the pilots monitored and Mscharatha operators on the ground, where they sit behind their desks in the Nevada desert to bouts of tasks than 4 hours.It has also equipped to set to Aazria devices and two air - the land of the type of Hellfire (Hellfire). The model is called the symbol of armed MQ-1.And developed the company «General Aironoticll continue» GAAS derived from Predator-A so-called Predator-B and became a weight equal to four times the weight of its predecessor, and added 6 meters on display wing to become 20.12 meters, and became able to carry a total of 1360 kg of ammunition, the equivalent of 14 rockets Hellfire, or 6-guided bombs each weighing 225 kg independence flight of 16 hours flight speeds of up to 370 km / h compared to 130 km / h A previous model. The aircraft flew from unmanned MQ-9A Predator B for the first time in 2001, they are high-altitude vehicles withstand long (Hale) and capable of reconnaissance and surveillance, targeting and throwing weapons as well. This plane is equipped increased the length of its structure to become a 10.97 m with a turbo fan engine. And operates at an altitude of more than 5,000 feet of any twice the height of the original vehicle. And studied by General Atomics manufacturer's ability Predator - b-carrying missiles Aim-9 and Aim-120 of Raytheon Company (Raytheon), in addition to the bombs «Boeing» SDB GBU-39 / B any bombs with small diameter, weighing 130 kg, the bombs GBU- JDAM, and precision-guided bombs to Aazaria and anti-ship missiles, such as missile AGM-84 Harpoon, which is produced by the Boeing Company.In order to be brought to the U.S. Navy substitute less expensive than the plane of the unmanned Global Hawk (Global Hawk), offered by General Atomics in collaboration with Lockheed Martin aircraft Predator B-ER or aircraft Altair, which has Bba wing longer and fuel further what gives resilient for a period of 49 hours and a ceiling of 19,000 meters.Take the vehicle unmanned air vehicle structure ER unmanned air Predator-B, with a longer wing sold 26.21 m. Thanks to appropriate additional fuel tanks with a steadfastness in the air about 50 hours. The maximum weight for takeoff 5000 kg Currently, payload useful amount of 1360 kg of radar operates at 360 degrees Center in pods under the forefront, in addition to sensors (EO / IR) and countermeasures (RF) and communications secure information intelligence, and with speeds of 315 km / h The period they can remain in the air less than 30 hours.* Gnat 750 (Gnat 750):Plane from an American drone flew for the first time in 1989. They can carry sensors Kahrobesria or thermal system also can be equipped with synthetic aperture radar SAR. U.S. intelligence has been used by the year 1994 in several functions in its operations to the former Yugoslavia. And weighs 520 kg and carry payload weighing 150 kg, and hold up to a 40-hour period. The ceiling is 7600 m but they are running a ceiling of about 4600 cm.

    * (Neuron):French government took the initiative to launch a program to develop the experimental model of unmanned fighter European  that may be flying for the first time in 2009. And on this plane to demonstrate their ability to perform more tasks demanding more conditions cruelty and to be fully integrated within an environment of war pivoting networking, as it should be up to its maximum possible degree of secretly through less imprint radar with detection X below the red. The plane approaching from the designated target from another source of information quickly without the speed of sound and fired ammunition hidden inside the structure.* Hunter RQ-5A:U.S. Army conducted a 2005 first test flight of the drone RQ-5A Hunter in a new design called the Endurance Hunter, has been expanding their range, sustainability and capacity to carry beneficial. The aircraft combines structure fixed wing and tail-to create a new caudal and medial wing longer to form a drone can perform tasks up to 30 hours at an altitude of more than 20 thousand feet. And can carry various external sensors, communications systems and useful loads of weapons. The booth sold amounts to 34 feet. Has provided the wing hard points capable of carrying 130 pounds of weapons and can carry 110 liters of fuel to increase the resilience of the plane additional six hours.The plane of the unmanned MQ-5B Hunter, which recognizes the U.S. Army first copy of which was late 2005 and put in use operational in April 2006 they developed so that it can carry guided missiles Joe - the land type Viper Viper or ammunition Textron Blu-108 containing 40 A small bomb which can fly for 21 hours continuously at an altitude of up to 1,800 feet.

    A promising future for dronesThe research and studies focused on military drone, due to the promising future, especially after the success of the recently recorded at the level of eavesdropping and targeting. U.S. Air Vslah works confidentially on the development of unmanned aircraft subtle supersonic long-range reconnaissance, and give the best intelligence leaders on constantly changing objectives in the war on terrorism and in other places, and also allows them to hit those targets. There will be a reconnaissance aircraft, but also required to also be able to attack the enemy. On the other hand, U.S. military officials called senior intelligence tools more flexible than satellites, considering they are often transient or lacking in accuracy of performance track Shuffle goals. The plane without a pilot high-speed and long hidden the extent you can reach the hot spot quickly and without the discovery of remains for a long time.
