A rough and ready test for self sustain speed - just made it to 35000 rpm - strip and modify again .
The Jet Engine project was one of the more eye opening projects that i have ever completed - the shear power and energy produced by an engine of this type is unbelievable
until it is witnessed first hand. This type of Miniature Jet Turbine was a first generation attempt at obtain a usable Jet engine for model aircraft and used a Turbo Charger Turbine and Compressor.
My MK2 Jet self sustains with the correct exhaust temperature but with little use able thrust - it has been retired as "show your friends" piece that sits on the shelf.

This section of the page presents details of the Gluhareff pressure jet, an air breathing engine with no moving parts apart from valves.
The Gluhareff pressure jet is a remarkable engine. It is a pure jet, producing thrust using the standard open Brayton cycle sequence of compression, heat addition by combustion, and expansion.
However, unlike the gas turbine, the work required for compression of the air is not obtained by mechanical work extracted by a turbine in the hot gas stream. Instead, the compression is driven by a Rankine cycle using the propane fuel as the working fluid.
Heat from the exhaust gas is used to vaporize the pressurized liquid fuel. The hot, high pressure propane gas is then expanded through a sonic nozzle into a series of intake ducts, where it entrains and compresses enough air to support approximately stoichiometric combustion.
The three entrainment ducts have specific lengths, which results in acoustical pumping of the air well in excess of the compression achievable by simple momentum exchange between the fuel gas and air.
The engine has no moving parts except for a throttle control valve. In contrast, a gas turbine engine has rapidly rotating, highly stressed components, some of which are operated at the temperature limits of materials for hot oxidizing environments.
The lack of moving parts makes this engine very lightweight and cheap, compared not only to a turbine engine, but even to a mass produced automotive engine. However, the current engine runs hot, has a high frontal area per unit thrust, and a somewhat awkward geometry.
The Pressure jet Engine has a fuel consumption in between rocket and turbine propulsion, but at a lower cost than either.
The engine in the plans is the G8-2-5. The pressure jet was invented and developed by one man, Eugene M. Gluhareff - these are free jet engine plans for download.

Plans for an old "Pre-Shreckling" prototype Jet Turbine Engine - plans are incomplete and not detailed. The design probably would not produce enough thrust to be anything more than a static display model if it could reach self sustain speed. Obsolete Design and very heavy build. Often sold as Home built Jet Engine Plans
UPDATE - after a little searching I found the source of the plans - the infamous Savoy Scientific "Screamin' Demon" - have a look at this site for more info - http://screaming-demon.com/ the man who paid for the plans was far from happy. It is rumored that these Turbo Jet plans (if they can be called that) are still for sale today on the web - beware of any daemon you may come across while searching for a Jet Engine Plan - you may be a victim of one of the longest running Jet Plan scams of all time.
The new online seller of this attempt at a miniature Jet Turbine Plan Set now includes a claim that their plans have been "expanded to include all necessary details"
This proves that the plan set in it's previous format was incomplete - and is still based on the obsolete and non practical Savoy Daemon Gas Turbine prototype.
The video on the new seller's website is not the Jet engine in the plans - big heavy, overweight with an exhaust nozzle glowing red to white hot just proves that the seller has no idea how a true miniature jet turbine engine should look and perform.
Just imagine having a red to white hot fire bomb inside your RC jet!

Build your own high powered jet turbine engine
by John Tomlinson
This page contains plans and information on working miniature jet turbine engines and there is a Jet Turbine Engine Plan for a budget price of US$ 9.99
The plans are of models that are generally regarded as obsolete in the rc jet world, but they are an ideal starter if you wish to make your own jet engine
Research the subject well before you start. There are lots of forums, groups and websites to help you.
I purchased "Gas Turbine Engines for Model Aircraft" by Kurt Schreckling, ISBN 0951058916 Traplet Publications - all you need to start.
