Abstract

The jet engines are either fuel consuming or have shortage of power. Thus a new type of engine with a better design and less of drawbacks. The resultant jet engine is a hybrid of the pulsejet engine and turbojet engine. The combustion chamber of turbojet is replaced by pulsejet engine. The pulse jet used in a valve less pulsejet or thermo jet. Since the combustion chamber and high pressure compressor blades are replaced with much simple pulsejet, thus the overall weight of the engine is reduced. The air entering the engine is divided into two parts, one passes along inner surface area of the turbojet casing and other part goes through the pulsejet for the combustion. The air passing though inner surface area acts as cooling medium for the pulsejet and will contribute for the thrust as it will increase the total mass flow rate at the downstream end of the engine. Mechanical efficiency of the engine will be increased as the moving mechanical parts will be decreased. Augmentor will be added later on for the pulse jet to increase the overall efficiency of the engine. If required a variant with afterburner can also be inducted
