The isolated hose and the support hose
The isolated hose
The isolated hose is responsible for two tasks. The first task is to fix the high-altitude wind power
station at the earth and the second task is to forward the hot air.
The isolation is done by a vacuum or by aerogels.
In the outer section there is space for generating uplift with additional room for Helium.
The support hose
If this is not enough, there can be additional hoses installed, which have only the goal to generating uplift for
the platform of the high-altiutde wind power station.
The hoses are working by the Archimedean principle. This means only the volume and the difference of the
air pressure is important for the uplift.
These hoses are called "support hose".
The hoses are starting at the surface and going to the wing.
One support hose can lift the weight of the hose. If the weight is higher, it is possible to add more support hoses.
For the scope of the scalable prototype an isolated hose is developed and tested.
The preferred material is a carbon fiber with a high tensile strength.
If around the isolated hose of 2,5 m an additional hose with an diameter of 3,5 m is added the uplift is
around 31 000 kg.
An hose for example behind this hose with a diameter of 2,5 m generates an additional uplift of 32 000 kg.
