AeroVironment RQ-11 RAVEN
In 1999 year to the needs of the US Army, the US government purchased 4 RPV FQM-151 Pointer, for testing advanced technologies of the military operations in the settlements. Complex Pointer helpful, but impractical because of the large size of the ground control station. Therefore, by order of the US Army company was engaged in the development of Aero Vironment NSO smaller dimensions. However, the new complex was also more compact UAV called Raven. From the "Pointer" he was about 2 times smaller. The first prototype of this device, called Flashlight, was first flown on October 2001 city In 2002 year above him we had a number of improvements, and the final version was naming Raven («The Raven").
The prototype "The Raven" was made by hand and are not suited for mass production. Therefore, the first batch of released remotely controlled aerial vehicles has small volume, had the name of Block I Raven and released in 2003 In this version of the UAV fuselage was completed with easily replaceable bow department payload. Testing of this device helped find a lot of shortcomings, which experts attributed the unsatisfactory stabilization UAV in flight and the difficulty of planting machine.
These shortcomings managed to fix the machine "Raven, Block 2", he entered the US Army in the autumn of 2003 years. He checked in combat operations in Afghanistan, and in the 2004 179, the government ordered complexes "Raven", each of which comes with three UAVs. In the ranks of the army UAV "Raven" was designated RQ-11A.
In fact, RQ-11A - it is a smaller version of RPV FQM-151 Pointer, but through the use of improved technologies capable of carrying the same payload, control system and navigation system. To adapt the transition to the production of "Pointer" on the company Raven was not difficult, because they almost have the same structure and the target load.
Raven UAV takeoff weight of 1,9 kg, range - up to 10 km, duration of the flight - about 80 minutes. The device operates flights between speeds of up to 45 95 km / h at altitudes 30-300 m.
UAV RQ-11A can be controlled independently of GPS-navigation or in manual mode with a ground control station. One click drone operator returns to the starting point. The standard target load consists of a color CCD cameras or infrared cameras
Raven - the smallest UAV in the US Army, but its effectiveness in carrying out intelligence operations has allowed the model to fill the niche battalion level, where the use of larger UAVs unprofitable.
Despite the small set of features compared to other tactical UAV, Raven sends units in real-time intelligence required large amounts of information that previously could only get the highest levels of command.
Equipment UAV is not new to the military. But as its use meant taking off from the runway and the availability of qualified personnel, drones actively exploited only the highest-ranking command units. Passing on lower levels, information can often become outdated and irrelevant to the battalion. Also, based on the fact that one UAV in one sortie carried out several tasks, sending information carried out on a priority basis. Having our own UAV Raven in the ranks of the battalions allows immediate overflights places of interest for detailed exploration, which minimizes the risk to soldiers' lives by providing them with relevant information about their surroundings.
The price of one UAV Raven - 35 thousand. $, The cost of the entire complex - 250 thousand. $.
