|AV 1 - The first hot-air dirigible airship, formerly in the colours of TICO Prague, now Coca-Cola Moscow||AV 2 - for Slovakian customer - Reprox Kosice|
Offical stand from the sales department:
We have postponed the investment of further time in this project being too busy with balloons and standard price-list production. We would be glad to offer the development of the airship as a joint project with a partner/investor. The price of a new airship would be about 2.200.000 CZK, with delivery in about 10-12 months.

A lot of successful test-flights followed. Some of them during balloon fiesta Kosice '99 (see www.balon.sk).
The new Kubicek AV2 airship is participating as a fiesta aerostat at the World's in Bad Waltersdorf, Austria 1999.
It has an honour to promote the 7th Hot-Air Airship World Championship in this area for the next year - September 2000, flying over the most popular places over there - Bad Blumau Hotel and Schielleiten castle.
Together with the Cameron DP 90 airship. As a spectator you canďż˝t help admiring the elegant "cigar" shape of the AV2.

2. Description of Component Parts
The car of the airship is a traditional welded latticework with a composite covering riveted to the frame. The material used is the most durable chromium-molybdenum steel, class 15 130 (EURO - 25CrMo4), while the covering is made of laminated plastic. The car is equipped with nose-wheel undercarriage, which is doubled in front. The fuel tank is located underneath the middle seat. The basic flight arrangement is as follows: 3 persons and 3 gas cylinders.
The envelope is equipped with a rip panel. The tail areas are filled with air and are without supporting structure. The envelope is made of special extra durable PES fabric, designed and manufactured exclusively for the airship. The car is hung up on the envelope by means of the inner suspension. Safety envelope valves are located on the car and on the envelope.
The power unit consists of a Rotax 503 UL-2V (two carburettors) in standard push configuration.
The engine bed is a reinforced aluminium board, vibrations are absorbed with silentblocks.
The propeller used is a two-blade wooden V-230C type.
The heating unit is a burner AV2, using spirals of H3-D type with added electrical control.
Fuel cylinders for gas used in our airship are the same type as in hot-ait balloons.
The equipment provided with the airship is installed in the car and is accessible from the left seat. It consists of the instruments for hot-air balloons (a Flytec 3040 instrument that combines a variometer, altimeter and thermometer, fuel gauges attached to the bottles and pressure gauge attached to the burner). Furthermore, there are several airship-specific instruments: air pressure gauge for measuring the air pressure in the envelope, fuel gauge and engine speed indicator, and a watch. A common portable radio transmiter is expected to be used during airship flight operations.
Electrical wiring is a central jointing sleeve connecting the engine, auxiliary fan and other appliances.
Fuel lines for petrol are made of stainless steel tubes, the gas lines are the same as that used in hot-air balloons.
