A 4K Albatross

Design of unmanned aircraft A-4 «Albatross" began in 1998 year. For its creation were set specific tasks in the first place they touched zoom range in comparison with the type of UAV "Remez". New UAV should run away 20 km. Engineers from CB "Rise" had not only to increase the size of the aircraft, but also to use a new and powerful radio transmission of video and control.

As part of the "Albatross-4» complex remained the same configuration as that of the "Remez-3». But the overall look and feel of all the equipment have changed dramatically.

Scheme A-4 «Albatross» classic - cantilever monoplane with a pusher propeller. Strongly elongate fender provides high aerodynamic characteristics of aircraft quality and sufficient stability, regardless of whether or not the engine is running. The wing structure applied flaps, which improved takeoff performance UAVs. But at the same time in the rest of the "Albatros" is very similar to "Remez". The new machine has applied proven practical solutions. "Albatross" carries off using a wheeled chassis, which requires 75-meter flat ground. With some modifications, you can use the catapult. All flight mode is possible in two ways: manually (operator command) and automatic. In both types of indications of location management trajectory parameters are determined and GPS-35 receiver. After processing, the results are transmitted to the PC monitor, which is part of the ground complex.

In carrying out flight out of sight of the machine operator image is from the small-sized video camera installed in front of. Coursework camcorder can be operated at low light levels. For example, in the twilight. Sufficient stability of the aircraft in flight maneuvers and high wind speed provides the navigation PNA "Rise" complex.

Watch the terrain can be with a camera with interchangeable lenses. The camera is mounted on a swinging platform, which may deviate in two planes of operator commands. This functionality allows you to see objects that are on the side of the flight path, and the UAV does not change course. Also, thanks to this platform "Albatros" can perform target tracking within sight.

A novelty in the A-4K a parachute landing system with forced ejection of the dome. The parachute is produced not automatically, but only by the operator. But in the case of an emergency stop of the engine, in excess of the minimum and maximum altitude, and in case of power failure of the parachute release automatically. forced landing coordinates are also automatically transferred to the operator's monitor. Thus, the new parachute system not only allows you to save the device from damage during landing, but also greatly simplifies its operation.

Landing on the wheeled chassis is much more complicated. Tests have shown that the UAV control when planting should be engaged in highly skilled and experienced operator. Flight tests began in 2000 year. The first UAV used in different climates with different geographical location.

Another direction of improvement of the basic model relates to a new system of governance, which should be implemented fully autonomous flight on the desired curved or closed route on the basis of high and productive digital computer. In addition, the Bureau were working to reduce the impact of internal and external interference on the stability and performance of steering actuators and control systems.

Thus, to test the aircraft design characteristics built a prototype UAV A-4K "Albatross", which the trial began in December 12 2001 years. They were successful. In addition to the sample examined by the use of compact cameras for surveying. "Albatross" is tested so far.
