Gas turbine theory

Tweet The video showing the destruction of 46 of the 55 Chrysler Turbine Cars we posted recently generated lots of heated discussion.

Gas turbine theory

Why build a gas-turbine engine? What materials will I need? Choosing a turbocharger 5. Where do I get some plans? What Is The Combustor? Choice of fuel 8. Where can I find out more about gas turbine engines? Please note that this is a "work in progress" and Gas turbine theory such it may be incomplete in some areas and pleading for input from YOU in others.

A Foreword On Safety: The dangers associated with a gas-turbine engine are manifold and include: This generally means a foam, dry-powder or CO2 extinguisher -- the garden hose will be useless against a gas or liquid fuel fire.

However, having said that, do make sure that you have a bucket of cold water available just in case you sustain burns of any kind. Burns should be treated Gas turbine theory immediately immersing the affected body in cool not icy water. This is faster than a bullet fired from a handgun so, should a critical failure occur, there is a very real risk to life and limb if you are in the way when it happens.

A good rule of thumb is that you should never stand in line with the turbine disks or the end of the turbine shaft at the exhaust or intake. While there have been only a few incidents reported where a turbine has suffered catastrophic failure and, to the best of my knowledge, nobody has been injured in such an event, the potential for severe injury is significant and should not be treated lightly.

This is particularly true of larger turbocharger units with bigger turbine wheels. Treat all tools with respect and always use an isolating transformer or residual current device where appropriate.

When welding, always use protective eye and handware! Remember -- building and running these engines can be a lot of fun -- but not enough to lose an eye, a finger or a life for. I doubt your household insurance will cover "destruction by homebuilt gas-turbine engine operation. This is the question that DIY gas turbine engine builders are most often asked Most builders, at some stage or another, at least give passing thought to putting their engines to work powering a gokart, bike or some other vehicle, however few ever seem to get around to that.

This varies widely -- depending on how sophisticated you want to make your engine. Some turbine builders have gone to extraordinary lengths to add such things as electronic engine management systems, strain-gauges to measure thrust, a dashboard full of dials to display every possible operating parameter, etc.

Others have done little more than wire a few bathroom plumbing fixtures to an old and tired turbocharger then feed it with some fuel.

Both approaches seem to produce results. Some builders have welded these up out of 1" square-section steel tubing which is easy to work with and very economical.

You can buy special turbocharger hose which is often a silicone type or you may find some reinforced rubberized tubing. If the gods are smiling, you might just stumble on something bigger -- perhaps the turbo off a large diesel engine.

Be aware that any damaged turbo can be little more than a grenade waiting to explode -- and the bigger the turbo, the bigger the potential bang. These wheels will be spinning at up to K RPMs so you want them to be perfect!

A damaged turbine wheel will almost certainly cause a balance problem and that spells big trouble and the risk of catastrophic failure. Now check that the turbo turns easily.

Most smaller turbos use hydrodynamic bearings ie: Check the bearings for wear by trying to push the compressor end of the turbo shaft from side to side by gripping the nut on the compressor wheel.

Also check the bearings for axial play -- ie: Take a look at how carboned up the exhaust turbine wheel and inlet housing is.History of Gas Turbine Theory The earliest example of jet propulsion can be traced as far back as an Egyptian namedHero.

Hero invented a toy that rotated on top of a boiling pot due to the reaction effect of hot air or steam exiting several nozzles arranged radially around a wheel. A gas turbine, also called a combustion turbine, is a type of continuous combustion, internal combustion engine.

There are three main components: An upstream rotating gas compressor; A downstream turbine on the same shaft; A combustion chamber or area, called a combustor, in between 1.
