The aerostat is capable to increase both: efficiency and range of modern portable radars. Additionally the complex can be equipped by high resolution stabilized camera and infrared camera. Altogether it can be used as a powerful border guard with the 70-80 km range. Some other uses are possible: early detection of forest fires, continuous surveillance of sea borders, detection of illegal craft and fishing etc. The multifunctional aerostatic carrier Au-27 has been designed to be used for a vide variety of purposes that can be classified as follows application field:
Communications.

Surveillance.

Scientific researches. Advertising.

Aerial photography, TV filming and broadcasting.

 Aerostat single mission endurance is 15 days at the working altitude. Brief landings (1-2 hours) for maintenance between missions are required.Aerostats are produced from the modern high-tensile fabrics and have aerodynamic form, which allows to operate them at the working altitude at 25 m/sec (90 km/hr) winds.Constant energy supply to Aerostat board is provided by the cable-tether. This energy ensures continuous work of observational camera and air-gas system of the aerostat.

We have both Russian and foreign cable-tether suppliers providing us with very wide range of this high-tech product. This cables provides reliable connection with ground equipment and proper power supply for different types of payloads.

Advantages of this system are:

1. Long endurance non stop missions.
2. Simple operation and service
3. Higher safety comparing to other kinds of air control vechicles.
4. Minimal crew.
5. Relatively low cost of the system.
The Au-17 and Au -27 is very cost-effective in operation. This conclusion is based on the fact that the aerostats used 20-25% less gas than any world analogue capable of accomplishing the same job. The second reason is low loss of helium, the third reason is that easy repair features enable the crew to make a simple repair
During the inflation and first lift the aerostat requires 4-6 people. The regular operation, including re-inflation and inspection requires 1-2 members of crew. The only exclusion is the flight with a pilot-observer.
The aerostats are equipped with the mooring system for stationary use. It consists of the mooring mast and fixing bottom ring both installed on the rotating mast and fixing bottom ring both installed on the rotating platform. The mooring system is capable to hold the aerostats in the 30 m/sec winds. The relocatable version of the above - mentioned system is available.
During short-term flights in remote areas there is a possibility to operate the aerostat without the mooring system using the traditional round shaped on-ground bivouac with 8 anchors. The bivouac can be used at the wind up to 27 m/sec.
