Precious light signals
Novice drivers often have no idea how to navigate especially in large cities. Skills acquired during the course of a driving license are often insufficient to freely continue driving after passing the exam. But do not scare initial failures in this respect - nobody immediately not yet led to any vehicle like a professional driver, and each kilometer is a valuable experience. It is worth noting that many motorists used polite rules on driving. A valuable signal to a driver who, for example, let us in on a congested intersection is sending him a thank you for using your own lights. Such light signals can be very useful when driving culture.
engine - wikipedia
An engine or motor is a machine designed to convert one form of energy into mechanical energy.12 Heat engines, including internal combustion engines and external combustion engines (such as steam engines), burn a fuel to create heat, which then creates a force. Electric motors convert electrical energy into mechanical motion; pneumatic motors use compressed air and others?such as clockwork motors in wind-up toys?use elastic energy. In biological systems, molecular motors, like myosins in muscles, use chemical energy to create forces and eventually motion.
Gas turbine cycle engines
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.
