I’m a second year BSc aerospace student in Holland, and I’m thinking about making a gas turbine engine. Normally on a turbo you can turn the comp and turbine scrolls (housings) on the core assembly. In 1972, he established EMG Engineering in Gardena, California, where he continued the development of the propane-fueled pressure jet engine featured here. In order to start the engine, propane gas is trickled in with a gentle flow of air from the leaf blower into the turbo inlet. At that point it goes back down to the inch or 2 and enters the hot power turbine which normally has 2 or more stages of blades and stators.

It needs to have an inlet of about 2.5 to 4 , no waste-gates and no bifurcated turbine scroll. Now that you have the rough dimensions you will be using for your jet engine, you can proceed to putting it together with the caps on the ends and the fuel injectors. A critical failure could be critical to you if any turbine parts brake through the casing, they could be moving at 1450 feet/sec In English that is 988 MPH which is faster than a bullet. Choose a jet with afterburner and record the thrust ___________ and the fuel flow ____________.

Therefore, coaxial shafts are made from Technic gear shift parts: pair of ‘Gear wheel Z16′ parts support each compressor/ turbine rotors, and driving- and middle rings connect them, running freely on main shaft. The engine is fueled by propane gas, the gas enters the combustion chamber via a burner ring made from copper pipe drilled with 1mm holes. His newer engine has also been freed from its palette mount: Tomko built a custom go kart to test it out.

You should make the jet removable from the CC for changing latter on, it should also sit near to the spark plug so that the gas can be easily lit. For a jet going slower than the speed of sound, the engine is moving through the air at about 1000 km/h (600 mph). The gas is flammable so why not burn it. Burning the gas with a normal burner would not use up the gas fast enough to give me any serious cooling. These homebuilt Turbine Jet Engines are fully throttleable that spool up and spin down sounding like their larger military jet engine cousins. This applet enables the student to interactively observe the effects of engine component performance on thrust and fuel consumption.

This book goes into just enough technical detail for younger readers, covering different types of jet engines, as well as broader details of how big planes stay in the sky. Packaged into the MW-54 size and weighing just over 2 lbs, this engine gives big performance at a fraction of the weight of other engines available in this thrust class. Use extreme caution; this is one of the most dangerous parts of the construction of your wind turbine. I start the engine by using a craftsman shop vac set to blow” mode (just switch the hoses around). I’m sure there are some very talented modellers out there will be able to take the off the shelf turbine wheel and go and produce a working RC Jet Engine.

This example of a homemade jet engine is about as simple as it gets, but it could not be used for propulsion purposes because it is only safe to operate for a short time. You will then need to buy or build a 2,000 to 5,000 watt inverter, we sell the plans for this. You need a usable amount of thrust before you can strap that engine to a go-cart and go cruising around the neighborhood. I also decided that the engine should do something useful, and not just make lots of noise and heat while burning up lots of fuel.

But in smaller size, lack of specialized TLG turbine parts starts to creep in the background: to save space, we have to omit multi-stage compressors and turbines, separate combustion chambers, internal electric drive, which are common in previous family. And, if you think a 55-gallon drum is going to do anything to reduce the damage or danger produced by a grenading turbine wheel then you’ve obviously never seen one let-go or calculated the energy levels involved! These images show the basic ‘tuned pipe’ without the spark plug and gas supply.

Have you personally ever built a gas turbine engine from scratch, from bits of raw metal to a finished running product?! A pulse jet is easier but the tubrocharger jet would be an interesting project from an engineering perspective. It is the only model in this handbook, which doesn’t have coaxial main shaft, because I experimented here with multiple stages of compressor and gas generator turbines. Product Description: This construction kit also comes with sound, with spinning turbo fans and a variable speed control, this is a brilliant way to understand the working features of the jet engine.

The transition bend had to be made for the application this engine will see in the jet bike, but it could have easily been made with just a simple straight-in rectangular section created from sheet steel. I was lucky to find two large Schwitzer turbo’s off E-Bay that were going cheap and were ideally suited as a jet turbine. The program begins with standard materials for the components, but you can change the materials and see the effects on weight of the engine. Spun-up particles fly into particle ducts bypassing the engine driven by their centrifugal force, while most of the clean air enters into the compressor.
