Jet Engine Design: Turbine Cooling

On May 1, 2013 · In Aerodynamics, Technology

As I described in a previous post, the efficiency of the gas turbine cycle increases as the turbine entry temperature (TET) is increased. Therefore the hotter the combustion gases that enter the first turbine stage the more specific power the jet engine can produce. Of course the TET is […]

Jet Engine Design: The Turbine

On April 6, 2013 · In Aerodynamics, Manufacturing, Technology

The turbine is at the heart of any jet engine with its primary task being to drive the compressor. As described previously  without the compressor no mechanical work would be done on the fluid prior combustion and the thrust produced would only be a function of the chemical energy […]

Jet Engine Detail Design: The Compressor

On January 11, 2013 · In Aerodynamics

In this post the design of jet engine compressors will be discussed leading to the definition of ballpark performance parameters. For smaller engines centrifugal (CF) compressors are used since they can handle smaller flow rates more effectively and are more compact than axial compressors. Axial compressors however have the advantage of a smaller frontal area […]

Jet Engine Design and Optimisation

On January 4, 2013 · In Aerodynamics, Case Studies

For aircraft jet propulsion there are in general four distinct designs: the turbojet, turbofan (or bypass engine), turboprop and turboshaft. This post will address the layout and design of the two most common engines used in modern aircraft, the turbojet and turbofan, and explain how their characteristics make each engine applicable for a specific task. […]

The Birth of the Jet: The Engine that Shrunk the World

On April 7, 2012 · In Case Studies, History

In today’s time it is easy to take for granted the complex inventions that alleviate our everyday life. The modern jet propelled airplanes for example, are one of the biggest drivers behind rapid globalisation and play a major role in world trade. Nevertheless, the development that revolutionised aviation and inaugurated the era of jumbo jets […]
