Download file to see previous pages The axial-flow engine functions by compressing the air through a series of rotating and stationary air-foils which in turn move the air parallel to the longitudinal axis. The centrifugal axial flow design, on the other hand, uses both kinds of compressors in order to achieve the desired compression.
This machine has four sections: turbine section, combustion chamber, compressor, and the exhaust. Inlet air passes through the compressor section at a high rate of speed to the combustion chamber. In the combustion chamber, there are fuel inlet and the igniter for combustion. The turbine is driven by the expanding air which is connected to the compressor by a shaft to sustain the engine operation. This kind of engines is limited in terms of range and endurance.
A turboprop engine is a turbine engine machine that divides a propeller through a reduction gear. Power turbine connected by a shaft is driven by the exhaust gases, and this drives the reduction gear assembly. Optimum propeller performance which is achieved at low speeds is brought about by the reduction gear. These machines are most efficient at high speeds of between 250 and 400 m.p.h and also performed well at slow airspeeds. These machines are nowadays used in small airliners and transport aircraft which are sufficient for landing and required for takeoff.
This turbofan engine machine combines the best features of the turbojet and the turboprop. Turbofan engines are designed to increase thrust by diverting the airflow around the combustion chamber. This only increase the thrust without increasing fuel consumption. This is because it increases the total mass of air passing through the engine reducing the velocity within the same energy supplied. Most airlines nowadays are powered by turbofan engines.
This machine is widely used in helicopters. Its a form of gas-turbine engine. It drives the helicopter rotor though it does not have a propeller.  ...Download file to see next pagesRead More

Gas turbine engine basics

...? GAS TURBINE ENGINE BASICS Introduction This paper discusses basic gas turbine engine operation, with the use of engineering drawings for depicting the engineering concepts explained. A gas turbine involves a combustion engine within which the accelerated gases moving through the engine nozzle is used to provide thrust, which drives the aircraft. Turbojets with converging-diverging nozzle (Sherwin, Keith & Michael, Horsley, 1996) There is an upstream rotating compressor that is coupled to a downstream turbine, and a combustion chamber in-between, and the accelerated...

High Bypass Gas Turbine Engine

Application of Newton’s First Law related to thrust: # If thrust and Drag are equal, the aircraft maintains a constant speed. # If thrust is increased, the speed of aircraft increases. Since drag is proportional to speed, drag also increases till it equals thrust. When drag again equals thrust, the aircraft travels at constant higher speed. Application of Newton’s Second Law related to mass flow and exit velocity: Force Mass * Acceleration F ma F=kma When SI system is used,the basic unit of force is the Newton, which is the force that will accelerate unit mass of 1 kilogram at a rate of 1 metre per second per second. Under these conditions, the constant k is unity. Therefore, F=ma F=ma=m di/dt=(m/ft) dV=d (mV)/dt =mass...

Steam Engine

.... Still it undeniably found many applications in terms of water works and was even tried to work mines though not quite successfully as its limitations became a hurdle in the way of widespread implementation in different fields of life like manufacturing and mining. In process of describing his invention to the public, Savery claimed that the steam engine invented by him could quite effectively drain mines and aid the manufacturing process in those mills and factories which do not have the natural benefit of water or constant winds. It could also be helpful in raising water and speeding up all sorts of mill work in addition to serving towns with water and all the while, using no manual or...

How gas turbine engine works consumption of fuel. This type of engines is designated to produce as much energy as possible this means that they should work on the maximum level of workload, if there are fluctuations in the workload consumption of fuel may increase significantly, thus making usage of such engine not reasonable. (Irwin E Treager, 78) Gas turbine engine technology has large perspectives. Nowadays scientists are developing gas turbine engines to be used in day-today life. Their capacity will help to improve and fasten lives of usual people. References Jan P. Norbye, Gas Turbine Engine: Design, Development,...

Gas Turbine Engine Compressors - Comparison

...Gas Turbine Engine Compressor A gas turbine belongs to the family of internal combustion engine. It is comprised of a rotating compressor, a combustion chamber and turbine. The compressor takes in the air at normal pressures and compresses it to higher pressures (Carl, 2002). This paper seeks to elaborate on the operations of the centrifugal and axial flow gas turbine compressors and expound on the advantage and disadvantage of each. The paper also seeks to explore recent advances that have occurred in the design of gas turbine compressors. Operation of the gas turbine centrifugal and axial flow...

Turbine-Engine Ignition and Starter Systems

...Ignition basis system Ignition basis system It is interesting to learn that the main turbine engines in aircraft operate with two ignition system. Each of the two ignition systems consist of an exciter, ignition plug and the ignition lead. The article has gone ahead to describe the functions of each of the parts aforementioned. The exciter serves as the power supply for the entire ignition system. As such, it provides sufficiently high voltage that is required to fire the igniter plugs. It is interesting to note that the ignition exciter operate at 24V, car batteries that operate at 12V. Similarly, the ignition lead works as the conductor of electric power from the source (ignition exciter) to the...
