UAV A-3 “Remez” was based on the first UAV “EYE-1”, which was designed in KB “Rise” in 1997. “OKO-1” marked the beginning of mikroapparatov various purposes. “Remez” first began testing in 1999. With a 9 kg weight UAV A-3 has a range of 5 to 20 km. Its flight duration is 2 hours. UAV is equipped with video camera and a real time electronic data transmission system.
Development of “Remez” began in 1997. There was a number of tasks that the unit should perform:
- With reference to the map of flight, the UAV is to detect a variety of objects on the ground and be able to determine their coordinates.
- Patrols of area and lingering objects.
- Scout areas of peat and forest fires, large technological catastrophes.
- Serve as an aerial targets for the combat training of air defense.
- Environmental monitoring.
In addition, the main task for the creators of the UAV A-3 “Remez” has been implementing the suitability of the complex to the hidden type of deployment on foot without the use of vehicles. Thus it was determined the small size of the UAV and ground equipment.Therefore, the complex included a UAV ground complex equipment. Complex used for transporting three containers weighing 15 kg each. Containers have the following dimensions – 0.4 x 1 x 0.4 m Especially for improving the complex had previously been constructed experimental UAV “EYE-1” and “Tit-2.”. First tested in September 1997. And the design work on the UAV A-3 “Remez” was launched in the next year. The original layout of the apparatus defined small size.
In UAV applied only suitable scheme – “Duck”, with a short fuselage, like the elliptical rotation of the body with a pusher propeller aircraft, which is installed in the ring. Using a power plant based on piston-engine D-23 (capacity of 2.5 liters. S.), And the aerodynamic configuration allowed for a large machine speed range. In turn, the opportunities to regulate the speed allowed “Remez” spending as random patrolling the area, and the maximum duration. In addition, the chosen scheme “duck” in the conditions of the output device in the critical angles of attack has a “spin” to ignore the property. He simply lowers altitude. To create the structure A-3 set of aluminum alloys was used. This design saves on production, as in the arrangement shall not apply complicated and expensive types of equipment. Furthermore, the used materials are of good quality and therefore provide long service life, durability and maintainability of the machine.
All equipment, including power plant, is located affordable and convenient. The instrument compartment mounted fuel tank. This compartment is closed a single access panel on the entire length. The power plant also closes a removable hood. Rich experience in the design and operation of experimental UAV “Tit” and “OKO” enabled the “Remez” less weight and smaller size.
Management of the UAV includes 2 people. Management process itself is available in stand-alone mode and by operator commands. The exact location of the aircraft and its trajectory parameters are displayed by navigation GPS-35 NAVSTAR receiver. The live onboard video camera image is transmitted in real time to the control station. The navigation is displayed on the computer monitor, and video on a small-sized monochrome display.
When landing the device uses a chassis. On production CB “Rise” was built from pre-series UAVs 2 A-3 “Remez”, which together with the ground control station form a full-fledged military complex. Flight tests began in 1998. According to the test results respectiveness of the aircraft was obvious. In 2001, CB specialists have started to create a universal modification UAV A-3 “Remez-U”. The new aircraft, in addition to other possibilities could dump small cargoes in specified areas. Another modification – “Remez-memory” – has been able to take off from a catapult. With additional improvements UAV can take off from the ground.
