Description

The The invention relates to a method for preventing condensation fill an aerostat, in particular a Heißdampfaerostaten, with a Supporting gas containers and a separate combustion chamber.

Background of the invention

When Aerostat are called balloons and airships. This term is derived from aerostatics, aviation due to different density distributions of gases. The balloons and airships, their best known representative the Zeppelin airships were "swimming" due to their static buoyancy similar in the air a ship in the water. Their locomotion is therefore called driving or Easier-than-air ride called. Generate planes and helicopters In contrast, their dynamic buoyancy through movement through the air. These The mode of locomotion is called flying.

When Carrying gas for Aerostats are in particular hydrogen, helium and heated air Accordingly, gas balloons with helium or hydrogen are known filled, closed and operated. hot air balloons are open and drive with the heated ambient air. Furthermore was suggested overheated Steam as a carrier gas for Aerostats to use. This is especially pronounced one inexpensive, non-combustible, invisible gas serving, namely evaporated water. At a suitable temperature, water vapor has almost ¾ of the buoyancy of helium, but more than twice as buoyant as the conventional one Hot air balloon. This aerostat is an insulated carrier gas tank for Recording the overheated Water vapor formed as a carrier gas. Among them is a separate from the carrier gas combustion chamber for the Heating with hot air formed to overheat the water vapor To maintain state. With the help of a burner, for example as a propane superheater burner accomplished is, the bottom of the carrier gas container is heated.

In the document DE 214019 A the use of superheated steam as a filling gas for aircraft is described. A method for replenishing airships while driving with superheated steam is from the document DE 240183 A known.

Around putting the aerostat into operation is in the initial state first empty carrier gas container to fill. Usually this is done with the carrier gas tank lying on the ground or added to an auxiliary construction. In connection with the Use of superheated steam It is also known to perform a so-called displacement Befülungs treatment, in the at an auxiliary construction of the carrier gas container initially filled with air and subsequently rinsed with steam is, until the formed water vapor concentration in the carrier gas tank a produces sufficient buoyancy. This procedure requires many times provide the carrier gas volume as a vapor quantity. The righting By means of the auxiliary construction also represents a significant limitation for the simple Operation of the Heißdampfaerostaten In contrast, let yourself in this known type of filling with the carrier gas container lying on the ground condensate inside the Hüllstoffs of the carrier gas container not sufficiently avoid.

Summary of the invention

task The invention is therefore an improved process for condensate avoiding filling an aerostat, in particular a Heißdampfaerostaten, with a Carrying tank and specify a separate combustion chamber, in which the practicality under normal operating conditions is reached.

These The object is achieved by a A method for condensate-avoiding filling an aerostat after the independent one Claim 1 solved. Advantageous embodiments The invention are the subject of dependent subclaims.

The Invention includes the idea of a method for preventing condensation Filling one Aerostats, in particular a Heißdampfaerostaten, with a Supporting gas containers and a separate combustion chamber, which comprises the following steps comprising: providing the aerostat with substantially evacuated Supporting gas containers, Tighten a sheath of the aerostat and gradual Erecting the aerostat by placing a gas at a temperature that corresponds substantially to an existing ambient temperature, and subsequently one over the existing ambient temperature heated gas in the combustion chamber are introduced, and finally filling the carrier gas tank with overheated Steam through a filling opening, the filled Steam in the overheated Condition is maintained by the combustion chamber is heated.

At the The aerostat can be provided on a substrate, in particular the ground, or be held on a rack.

With the help of the invention, a condensate-free operation after filling is made possible. Due to the avoidance of condensation, the constructive effort for the aerostatic decreases In addition, the performance of the aerostat is increased in this way, as to be supported additional weight in the form of the condensate is avoided. Condensate adheres to the case at about 100 grams per square meter, resulting in additional weight.

Compared to the filling process by rinsing would one Reduction of the filling time achieved by about 70%. The user of the aerostat will be on this Overall, easier management of the critical phase when starting the aerostat enabled.

A preferred development of the invention provides that the aerostat is designed in a stretched arrangement.

at an expedient embodiment the invention can be provided that when tightening the shell of the Aerostats and gradual Erecting the aerostat as gas introduced air into the combustion chamber becomes.

A advantageous embodiment the invention provides that when tightening the shell of the Aerostats and gradual Erecting the aerostat the gas is tempered with a hot gas generator.

Prefers provides a development of the invention, that when filling the Carrier tank overheated Steam filled becomes.

The Advantages of the invention unfold especially when used of the method described above in one of the embodiments explained for condensate-avoiding filling a steam balloon or an airship.

Description of a preferred embodiment the invention

The Invention will be described below with reference to an embodiment with reference on figures of a drawing closer explained. Hereby show:

1 a steam balloon laid out on the ground in an elongated form,

2 the steam balloon off 1 which is partially filled with air,

3 the steam balloon off 1 in the erected state, and

4 the steam balloon off 1 in the erected state, wherein a carrier gas container is filled with superheated steam.

1 shows a steam balloon 1 in the deflated state on a base, for example, on the ground, designed in an elongated shape.

As part of the filling process is then over an opening 2 the steam balloon 1 initially introduced air at a temperature which corresponds substantially to the ambient temperature. Using a hot air generator (not shown) is then passed over the opening 2 heated air introduced into a combustion chamber 3 is heated.

3 shows that due to the air with ambient temperature a shell 4 the steam balloon 1 Tightens and the steam balloon 1 then gradually rises due to the introduction of the heated air. The heated air preferably has an average temperature of about 100 ° C to about 260 ° C. In the in 3 shown, erected state is a carrier gas container 5 the steam balloon 1 above the combustion chamber 3 arranged.

Now there will be another opening 6 Water vapor in the carrier gas container 5 until it is filled. Subsequently, the further opening 6 getting closed. The steam balloon 1 is according to 4 ready for takeoff. The introduced in the carrier gas water vapor has a temperature of about 100 ° C to about 150 ° C.

The described method can in the same way for filling at be used in an airship.

The in the foregoing description, claims and drawings Features of the invention can both individually and in any combination for the realization of the invention in its various embodiments of importance be.
