Katzenfutter aus Griechenland mitnehmen?

ByAlina557

Hallo Liebe Community, Ich bin momentan im Urlaub auf Kreta und eigentlich wollte ich die Streunerkatzen dort füttern. Nun habe ich aber gelesen, dass das kontraproduktiv ist, da sich die Katzen dann an das Futter gewöhnen. Jetzt möchte ich das Futter mit nach Hause nehmen, da ich selbst eine Katze habe. Ist das überhaupt möglich…

Kann man auch ohne Abitur zum Fluglotsen werden bzw. gibt es irgendein Weg?

ByJakDan

Ich möchte unbedingt Fluglotse werden, jedoch kann man nur dich einen Hochschulabschluss zum Fluglotsen ausgebildet werden beim DFS. Gibt es kein anderen Weg? Ich habe im Internet recherchiert, dort steht, dass man es auch mit einem Realschulabschluss (mit C1 Englisch Kenntnisse) versuchen könnte. Könnte man nicht durch bestimmte Mittel und Wege z.B. mit bestimmten Personen…

I can prove you here now:

http://www.exl.at/helicopter/turbine/turbinen.htm

But I do not (yet)

Basically, a jet engine functions quite simply:

In the front part air is compressed and brought to high pressure. The compressed air is enriched with fuel and ignited in the combustion chamber. The hot gas expands abruptly and flows out to the rear. It also applies to the turbine blades which drive the compressor and, in the above engine, the fan (the large blade wheel at the very front).

The exhaust gas jet now acts as a thrust, but in the above engine also the ‘jacket current’ is the air that the fan pushes backwards.

Basically it was already, you can of course look even deeper, but then it becomes as complex as you like!

If you’re really interested, look at the link.

Isn’t the burnt air constricted at the end so that there is more thrust?

Quite roughly: air is sucked in at the front (left in the picture) by the turbine and pushed out at the rear (right) as a drive. I am not sure what is happening in the area of turquoise, red and lilan turbines. However, it could be an acceleration of the air sucked in, so that more thrust comes out at the back than is sucked in at the front as a draw.

A simple, but ingenious drive…In the engine housing (approximately centrally) there are several shovel wheels which are arranged from small to large in the rhey. This space is closed all around, causing the ignited cerosine/fuel to leak. They are thus driven by the cerosin burning in one direction, through the blade wheels. The drive turbine (blade wheels) are connected to the front large, and this generates the thrust.

An overpressure is maintained in the combustion chamber by combustion. thrust = differential pressure x free surface (nozzle cross section )

very roughly explained it is very simple…

front cold air pure->compression->h hot air out…

The air flowing into the engine is combusted by adding an “oil” and thus the volume of the cold inflowing air is increased. This air in the engine would like to get out “the one with the larger volume because hot”. This slides at the outlet of the turbine. And as a result of the volume increase (heating) of the inflowing air, there is a “bub” which drives the aircraft forward. The over/underpressure on the supporting surfaces generates the lift of the flyer. Greetings
