Classic small volume captive balloons, during the wind of 5 m/s and more, since the height of 20–30 meters, instead of lifting, is placed on the ground (because of the relatively high value of aerodynamic drag of the tether). Thus, the tethered balloon less than 30 m3 (this capacity can be compared to half of the capacity of railway tank) may be constantly in the air only in calm weather.
Hybrid captive balloons do not have this disadvantage because they combine the properties of a captive balloon and a kite. During the wind, the aerodynamic lift acts on the balloon in addition to the aerostatic force.
Moreover, when the wind, maximum lifting height of hybrid captive balloons more, than the calm, and their behavior in the air in a wind incomparably more stable than the behavior of classic tethered balloons.
Use of the Colibris hybrid captive balloons is suitable for video surveillance; reception, transmission and retransmission of radio signals; carrying out of research work; the efficient lifting of flags, pennants, banners.
The Colibris hybrid captive balloon can be constantly in the air. It requires only a short-term down-trip for replenishment of helium.
The Colibris is a family of small-sized hybrid captive balloons of different volume and are designed to various payload lifting.
Balloons can be delivered as separate items, and as aerostatic complexes.
An equipment for panoramic video surveillance, aerial photography, meteorological observations, air pollution control, scientific research etc. can be installed on the platform.
The Colibris hybrid captive balloons have a slightly flattened envelope with helium and а skeleton empennage.
