Turbocharged Missile Silo Jet
In this instructable I will walk you through on how to build your own missile silo carrying aircraft.
I attend ECAM La Salle in Lyon France.
This is an aircraft which carrys silos for 'missiles' that can be ejected from the airctaft.
We've all seen those awesime movies where fighter jets open a hatch and unleash beautiful looking
pipes that 'pop'. but usually these cost hundreds of millions of Euros. We are going to be making our own fighter
with its own silos or projectile chambers which can be open on demand. if you even want to take it a step further,
you can add a micro controller and a radio communication module to actually control it wirelessly.
So! are you ready to compete with the worlds biggest defence producers!? Lets dive in!!!
Supplies
3D printer
Cardboard (any thickness)
Glue(preferably hot glue, but super glue and others will work)
Tape
Cutting tool (scissors, knife...)
2 switches
Turbocharger Printing
Print the following files. These are the turbocharger parts. I advise you print the impeller upside down, so that friction between it and it's housing will not haunt you later.
Trust me>_<
I already designed all the files in fusion, except the propellers (not part of the Turbo charger).

If you want to learn how to design the turbocharger yourself, you can just watch a video on it
that's how I learnt.
These are for the turbocharger:
Silo Printing
These are for the Silos. I have intentionally left out the three big pipes because I found out they obstructed the assembly in real life, so just print the files here.
Note: these dhould be printed in multiples.
tbearing x6
tbottom x3
ttop x3
tcomponent21 x3
Assembly
After you remove the support material from the prints, it's time to assemble.
Start by gluing the two parts of the base together as in the image.
Continue by gluing these parts like so, 3 T-component 21s, with the base. that is, the parts with two holes each in them, you glue the notches on the base into the holes of the T 21s. In the second photo I highlighted them for clarity.
then add in the tbearings and glue them as shown in picture 4 and 5.
Then you insert each T-bottom(highlighted in blue) into the T-21s. I highlighted each of the three pairs in red in the second picture, again, for clarity.
You then insert t-top(yellow) through the top of the base and it fits into t-bottom as shown in the first image. t-top will go through the base and into t-bottom
Clip on the "parallel" into the threeT-bottoms. It's the gray peice in the second image
Add in the t-arm and a motor to move it in the hole as shown.
The motor goes into the rectangular hole in the base and the shaft goes into the hole on the arn highlighted in blue.
assemble the arm and the motor first, then put them into the base assembly through the rectangular hole.
The arm should hold t-bottom as shown in the third image.
The silo tops should now be able to move together if you assembled the parts well.
Turbocharger Assembly
Push in the imeller shaft into the impeller as shown in the second picture, and then glue on the square shafted gear. After that, glue on the square end of the gray shaft to the gear.
Put the assembly into the bottom half of the turbo-casing, and add the top half and glue them together.
finally glue that to the base
Note: forget about the floating gear you see now. When you add in the motor, then, you will connect it to the
gear.
you might also want to expand the shaft hole a little, depending on the size of your motor's
shaft.
Repeat the process for the second Turbocharger and...
Turbochargers DONE!!!
The Frame
You can just cut out any frame that looks good to you for your aircraft, I didnt really use a template, just got a bearing from watching some videos on how to make plane frames from cardboard.
For this step Just go watch some videos, I wouldnt wan't to limit you to the specifics of this craft, and it's not perfect anyways, so spur your imagination into action!!!
Then place your turbo chargers on each side, and the silo assembly in front of them.
Propellers
Wrap some tape on the shaft of your motors to make them thicker and then insert the propellers on to the motors.
Make sure the curved edge is the leading edge at all times and you'll have make sure you orient them correctly because one motor will face the front while the other will face the back.
In short:
Just make sure when they spin, they push air to the rear and the curved edge is the leading edge.
Cut a hole in the rear of your frame for the propellers to fit into.
Then glue them on to the frame like I did, but make sure they are aligned properly.
Wiring
The wiring is very simple...
Just connect the silo motor with the two turbocharger motors in series, and connect them to the battery.
make sure to fasten the battery to the frame any whhere you like, or you could use it to adjust the centre of
gravity.
Then you connect the two propeller motors in series with the battery.
I did this becaus my motors are rated for 6v max and mmy battery is 9v, but if you have a higher rated motor,
you can connect them in paralell for more power.
I used aluminium foil to make junctions for the connections because that was what was available ;p
But you can use any means you have to make the connections.
Note: add a switch anywhere in the two circuits like in the TinkerCad Circuit
I designed the circuit in Tinkercad, so you can just copy the image.
One Step Further
If you want to take this plane to the next level, you could add in an arduino, raspberry pi (any micro controller) and even an nrf 24lo1 Transmitter and receiver pair to control the plane remotely, and add in two servo motors co control the ailerons.
Conclusion
Making this project was a big step into the worldof DIY for me, and it was fun. I'm sure you will have fun too making this project and improving on it. Please do add in some tips and improvements if you think all this work was worth it!
