STRATOSPHERIC BALLOONS

Stratospheric balloons are mostly used by the scientific community to study the atmosphere, its chemistry and dynamics. They are also valuable tools for astronomers and biologists, or for demonstrating technologies.

Since 1971, Airstar Aerospace has acquired a strong experience in textile design and manufacturing of stratospheric balloons. Our balloons lift anything from a few kilograms to several tons and are able to operate at an altitude as low as a few hundred metres or as high as 40 km.

Open stratospheric balloons

Open stratospheric balloons are gaz filled balloons (hydrogen or helium). They have one or several openings which enable the balance between atmospheric pressure and the gas inside the balloon.

Characteristics

  • Flight duration: up to 1 week
  • Payload up to 2700 kg
  • Flight altitude up to 45 000 meters

Pressurized stratospheric balloons

Pressurized stratospheric balloons envelopes benefit from a very high level of tightness and from a strong reliability. Thus, long-term flights above inhabited continents are possible.

Characteristics

  • Long term flights: up to 6 months
  • Payload up to 50 kg
  • Flight altitude up to 20 000 meters
