# How to make a Turbojet Engine at Home

**How to make a turbojet engine at home: **Turbojet engine is a more sophisticated jet engine in appearance and have a more refined jet engine sound. However they are still quiet simple to make, taking a couple of tubes, drilling holes, some welding and some mathematics. Here the engine is two separate pieces the flame tube and the housing.

## Parts needed

**A turbocharger**

**Some metal tubes of different diameters**

**A spark plug**

**A spark generator**

### How to make a turbojet engine at home( The Maths )

So on to the maths and it is really quite simple just measure the diameter of the intake on the turbo times it by 2 and that is the diameter of your flame tube. For the length of the flame tube times it by 6.

On to the housing which the flame tube sits in, you need roughly a 15mm gap all around your flame tube requardless of its size unless its fuchin massive so just add 30mm to your flame tube diameter and thats your housing diameter.

The length of housing is same as flame tube and the housing end is extra and should be short as possible with smooth entry to turbo.

Now on to the holes in the flame tube which is where i get a little liberal with how to do this, You want the holes to get bigger as they go along so you get a nice even burn the first set of holes are for the primary air so its best to have lots of smaller ones to promote a more even mix then the other sets can be a bit more spread out. You may be able to play around with this for more power or easy start up extra but thats up to you.

To calculate these holes you need the area of the turbo intake and the first set must add up to 30% of this with the second set 20% and third set 50% so work at your intake area by doing pie r squared which is 3.142 times the radius squared (squared is number times itself like 4 times 4) then divide this number by 100 and times result by whatever % your after which will give you the area of all your holes in that section so you now need to decide how many holes you want then divide that number by the same amount which will give you the area per hole then do the pie r squared bit again on what you think they might be and trial and error will give you your drill bit size. no get to it.

**Housing**

**Flame Tube**

**Housing End****And now we will fix all the parts together and the final get engine will look like this.****Now just hook up the fuel tank with it and fire it up.**#### You may also read:
