Main article: Brayton cycle
A gas turbine is a rotary machine somewhat similar in principle to a steam turbine. It consists of three main components: compressor, combustion chamber, and turbine. The air is compressed by the compressor where a temperature rise occurs. The compressed air is further heated by combustion of injected fuel in the combustion chamber which expands the air. This energy rotates the turbine which powers the compressor via a mechanical coupling. The hot gases are then exhausted to provide thrust.
Gas turbine cycle engines employ a continuous combustion system where compression, combustion, and expansion occur simultaneously at different places in the engine?giving continuous power. Notably, the combustion takes place at constant pressure, rather than with the Otto cycle, constant volume.
Old models of agricultural machinery
Automobile is not only cars or motorbikes. Many fans machine collects all sorts of completely different equipment. They are often used to actively vehicles participating in field work. The use of such machines was quickly superseded by more modern equipment, but their nature has not changed. Often these age machines are really worth huge sums of money, and not everyone can afford to buy these stylish devices. Many of them are still working and fulfills its functions in the field. Many agricultural machines from different periods only takes on its value, and for collectors is a real gem. No wonder that organized various meetings and rallies for fans of old tractors, combines and so on.
How to strengthen the car paint?
Among the drivers are very popular preparations, which produce no doubt brilliance of automotive paint. Interestingly, many of these measures not only contains polishing agents, but also agents responsible for applying a protective coating on our car. Thanks to such treatment as pasting of the car, so we can not only improve the aesthetics of the car, but also the fact that the car paint will be preserved. This, in turn, it will be more durable and resistant not only to mechanical damage, but also resistant to corrosion and other adverse to paint processes. Concern for the car paint is so profitable, because we can thereby postpone the need for removal of rust and so on.
