A term "aerostat", or lighter-than-air vehicle is a result of merging two Greek words: "aer" - "air" and "statos" - "standing". Lifting force of an aerostat is generated by helium or hydrogen, confined into a spherical envelope. Density of these gases is lower than density of the surrounding air. Aerostats are divided into dirigibles (airships), free-flight balloons with a sphere-shaped envelope (stratostats), and captive (tethered) balloons. They take-off and climb by means of an engine; stratostats regulate altitude of flight by controlling mass of ballast (bags of sand, special systems). Captive aerostats ascend and descend using a winch connected with an aerostat by a tether. History of aerostats began over 200 years ago in France, when brothers Montgolfier accomplished the first hot-air balloon flight in 1783. In honour of the first aeronauts a spherical aerostat is sometimes called a montgolfier. Modern aerostats are reliable and safe vehicles employed in aeronautics as well as for performing special tasks. Captive aerostats are widely used as effective medium of outdoor advertising. Also, for instance, the aerostatic attraction Aerolift taking passengers up to 150 m high is built on the basis of a captive balloon Sports on free-flying aerostats is an exceptional spectacle combining in itself perfect skill of pilots and dazzling show in the sky... The Augur - Aerostatic Systems Company offers a wide variety of aerostats developed on the basis of up-to-date technologies and made of domestic and foreign component items. Lighter-than-air vehicles carry on board advanced control systems and latter-day safety systems. Original designer ideas allow significant drop of prices of aerostats offered by the company, which predefines high competitive ability and strong demand for all products of the Augur - Aerostatic Systems Company. As an advertising tool, the aerostat is unmatched. Observable surface, to which a company logo or information may be applied, is so large that it makes an advertisement both spectacular and memorable. The unfolded envelope of an aerostat 20 m high is equal to a football ground. For customers wishing to order custom-made aerostats, the whole scheme of project realization is thoroughly worked out. As a result, you will be offered an optimal solution, including times and costs. Aerostats of the new generation constructed by the Augur - Aerostatic Systems Company always find a market.
