Gas turbines are powerful, and are efficient machines that can deliver a very high power output with minimal weight. This is characterized and proven time and again by their impeccable power to weight ratio, which is a scale that is normally used to calculate the efficiency of machines that generate power. Gas turbines rank high in this regard and have a very high power to weight ratio, significantly more than what the other types of turbines offer.

Gas turbines are also very small, and this is one major advantage that they hold over the rest of the pack. Gas turbines are the smallest engines manufactured till date, and although breakthroughs in technology are occurring every now and then, no other engine can offer such high power with such minimal weight. The dimensions of a gas turbine are less, and a gas turbine can garner almost twenty two Newtons of thrust, which is enormous given its size.

Another major advantage of using a gas turbine is the low operating pressure involved. These turbines work with low pressures, so the chances of error and engine breakdown are lesser. These engines also move in only one direction and this is one factor is also important because this significantly reduces the engine’s vibration to a very large extent. This is one of the main reasons why gas turbines are preferred over other conventional turbines. Gas turbines are equipped with compliant foil bearings and they can thus withstand a lot of start and stop cycles easily. This is good, as their need for a basic oil system will also be eliminated this way.

The number of moving parts is the engine are also fewer, thus there is lesser complexity involved with gas turbines. The overall layout of a gas turbine is very simple indeed. Gas turbines also require less lubrication than the other types of turbines. These turbines require less lubricating oil, and thus you can save good money on lubrication costs. All these advantages, combined with the enormous power that a gas turbine can generate explain the dominance of this type of engine in the industry.
