Everything You Need to Know about the Air Starter

With the innovation of diesel and gas turbine engines, it is imperative to have something that is powerful enough to get these things moving! They need an initial jolt, which will start their rotation. An air starter is responsible for delivering this energy to the engine and giving it the power to start its initial rotation. They’re typically used in gas turbine engines and diesel engines, but they can work differently in both regards. So, what exactly is the air starter and how does it work? You will be able to find the answers below.

Diesel Engines

The air starter is capable of kick starting diesel engines in two different manners. First, there is direct starting. Air is used to begin turning the pistons and forcing it downward. Once this is done, the engine will begin to turn and the air starter on the next cylinder will line up properly, in order to continue the movement. Once all of the indication cocks have been filled successfully, the engine can be given fuel and started.

On the other hand, it is also possible to use the air starter to drive a fluid motor. This is typically done in the form of a starter motor. In order for this to be possible, the starter engine must be between 5 to 320 liters in size. If more power is required, it is possible to use two motors, instead of one. Typically, these motors are used to replace electric motors, since they’re much lighter and much more reliable.

Gas Turbines

Of course, these starters are also capable of helping to start turbine engines. In this manner, the motor typically consists of a radial inward flow turbine. This component is equipped to a high-pressure compressor spool, which connects through the gearbox. Compressed air is entered into the system and is capable of starting the engine. Typically, the air is introduced to the system by a bleed air, which is connected to the aircraft’s auxiliary power supply. An air compressor can be used as well.

Major Advantages

Over the past decade or so, the air starter has become tremendously popular and is still growing in popularity. This is the case, because the technology is so advantageous. Typically, the main advantage is the machine’s power-to-weight ratio. These starters are lighter in weight, but just as powerful as some of their bigger counterparts. At the same time, it is essential to remember that electric starters require wiring and can actually become extremely hot, during operation. This is not the case with air starters. They’re capable of running as long as needed, while air is being supplied.

Whether used for diesel or turbine engines, these starters are much more simple and are typically a better fit. This is resulting in these starters being used much more frequently on military and commercial aircraft, as well as within various industries.


When engines become more powerful, strong and better capable starters are required. This has brought about the utilization of the air starter, which is lighter, more efficient and easier to use. Air starters are also generally more durable and tolerant to harsh environments making them the choice of a great number of construction, trucking, marine, oil & gas, and other types of customers worldwide!
