A thrust system is a thrust generating machine for moving an object. The thrust on planes and spacecraft is produced by Newton’s third law of motion. The fluid (air, etc.) in the engine is accelerated by the engine, and the reaction of this accelerating fluid creates a force on the motor. The amount of thrust produced depends on the mass flow in the engine and the rate of gas exit. Different drive systems can produce thrust in different ways. There are several drive systems technology, including propeller, turbine (or jet) motor, ramjet and scramjet and ion motors.
Why are there different types gas turbine engine systems?
When we think of Newton’s first act of motion, an aircraft propulsion system must serve two purposes. First, the propulsion system provided by the system must balance the drag force on the plane in the positive direction while driving. Second, the thrust in the propulsion system must exceed the drag force of the aircraft in order to accelerate the aircraft. The difference between thrust and friction is called “excess thrust”. Almost all planes (such as civilian passenger planes, cargo planes, etc.) except for war jets are the cruise we call flat flight in the vast majority of their flights. The excess thrust value for these planes is not as important as the engine efficiency and fuel consumption values.
Optimum efficiency and consumption are aimed. Since the amount of impingement depends on both the mass of the fluid (gas) in motion and its velocity, we can produce a high thrust by accelerating the high mass gas to a low amount or by accelerating to a large amount of low mass gas. Aerodynamic efficiency of the propellers and fan blades allows a low amount of fluid to be accelerated at a low rate, which saves fuel compared to the other propulsion principle. For this reason, we use high bypass fans or turboprobe engines on aircrafts except the warjets.
The use of turbojet engines in warplanes has a short period of time to achieve high acceleration, reaching sound speed, and extra power with afterburning. In these engines, fuel consumption is less important.
