If you encounter turbines on a daily basis, then you must know that turbine starting is not as simple as it sounds. People normally think that a plane is like any other machine, you put in the key and then everything should start working just fine, but owners of planes and those that provide maintenance for it know that it takes an electric motor to spin the main turbine shaft. Only when there is enough air going through the compressor that the engine starts to roar to life.
Now, these electric motors aren’t too cheap. Well, some are, but they don’t necessarily last long – some are even faulty. If you’re an airline company, or maybe a company that provides aviation maintenance then you know that this is something that you should really spend a lot on for its quality and durability.
Different models out there come with different power production mechanisms. Some are chemical-based, such as lithium (just like your traditional battery), some are a bit more reliant on traditional technology like gasoline and diesel. Although changing times have also brought forth the more versatile hybrids, such as diesel electric hybrid GPU, which is definitely a must-have if you want to be a little bit more on the safe side. There are also different models that vary in size, depending on your needs.
It’s best if you try and evaluate your needs before purchasing these types of equipment; but never compromise between price and reliability. It’s better to pay more for something reliable than less for something that’s not.
