drive a propeller. The gas turbine is designed specifically for this application‚ with almost all of its output being used to drive the propeller. The engine’s exhaust gases contain little energy compared to a jet engine and play a minor role in the propulsion of the aircraft. The propeller is coupled to the turbine through a reduction gear that converts the high RPM‚ low torque output to low RPM‚ high torque. The propeller itself is normally a constant speed (variable pitch) type similar to that used

speed jet (see Newton’s Third Law). Chemical rockets‚ the subject of this article‚ create thrust by reacting propellants within a combustion chamber into a very hot gas at high pressure‚ which is then expanded and accelerated by passage through a nozzle at the rear of the rocket. The amount of the resulting forward force‚ known as thrust‚ that is produced is the mass flow rate of the propellants multiplied by their exhaust velocity (relative to the rocket)‚ as specified by Newton’s third law of motion

Statement of Purpose “The thirst for knowledge increases with the acquisition of it” –Thomas Carlyle‚ is something I truly believe in‚ thus realized early that diligence is the only investment that never fails. That one quality which‚ intrinsically motivates me‚ is my Never-Say-Die spirit‚ besides finding out how does a machine operates? I’ve always been interested in design aspects and monitoring the incipient faults occurring within machines. This urge has strengthened my ability to look beyond

DESIGN OF TESLA TURBINE Abstract:- The Tesla turbine is a bladeless centripetal flow turbine patented by Nikola Tesla in 1913. It is referred to as a bladeless turbine because it uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional turbine. The Tesla turbine is also known as the boundary layer turbine‚ cohesion-type turbine‚ and Prandtl layer turbine (after Ludwig Prandtl). Bioengineering researchers have referred
