3D Printable Jet Engine, motorized by Rolumix

Last crawled date: 3 years ago

This is a remix of the excellent 3D Printable Jet Engine by CATIAV5FTW.
I modified various parts to incorporate an electric motor, to animate this wonderful model.
Print time of the set: 190 h 30 minutes. About 1,5 kg PLA
Stay tuned with the details evolution by checking the Watch box.
You will have probably noticed, this is a remix of the work of CATIAV5FTW for which I have the greatest respect, being well placed to know the amount of modeling work that it cost him.
This is why you will not find here all the STL files of this model, but only those that I have modified. You will have to download the files of the original object deposited by CATIAV5FTW and especially read the indications that he was kind enough to write. Also note that the STEP file of the complete assembly modified by me is available among the files that I have deposited which will allow those who wish to modify parts in turn and generate new STL files.
Regards and good 3D prints

Optimization of "Coupleur_Moteur-arbre basse pression_V3".
This set of 2 parts provides the connection between the electric motor and the low pressure shaft of the model.
It allows a slight misalignment of the electric motor
When the engine is stopped, it allows the low-pressure compressor to spin
(People are curious and will turn the turbine by hand if you have your back turned)
Without driving the geared motor, which is not necessarily reversible with a low torque.

The "coupleur_moteurV3" printed with PLA does not have the desired endurance yet.
I reprinted it with the Colorfabb XT-CF20 and the result looks better.
So I will test a 3mm V4 extension, with PLA to see if things
always move in the right direction. I want to avoid the obligation to use something other than PLA for this part that gives me a hard time.
It is also necessary to use PLA of very high quality, otherwise it breaks.

The model came back from the Paris Air Show. It operated autonomously (on batteries) more than 10 hours per day, for 7 days. 2 x 9V batteries ensure a minimum of 25 hours of operation at 1Hz. With all the batteries a minimum of 100 hours operating is OK.
For the show, I installed a coupler V1, the model being in showcase and the V4 couplers not having the reliability that seemed to me necessary.

At the request of OLGA_M, I divided the stand in two parts Left and Right to print on a smaller 3D printer.
STL and STEP files provided.
Supports needed.
A recess has been made to facilitate the alignment of the parts for assembly by gluing.
A pedido de OLGA_M, dividí el soporte en dos para imprimir en una impresora 3D más pequeña.
Archivos STL y STEP proporcionados.
Apoyos necesarios.
Se ha realizado un rebaje para facilitar la alineación de las piezas para el ensamblaje mediante encolado.

To answer Olga's question about the two sets of axial clearance, I added a sectional view with arrows indicating their location. The thickness of these shims depends on the accuracy of your prints and must be adjusted accordingly. In the best case, they will not be necessary
Para responder la pregunta de Olga sobre los dos juegos de juego axial, agregué una vista en sección con flechas que indicaban su ubicación. El espesor de estas calzas depende de la precisión de sus impresiones y debe ajustarse en consecuencia. En el mejor de los casos, no serán necesarios.

Hola Olga
La parte marcada con 1 es el eje de salida del motorreductor de su elección.
Las otras partes son hardware estándar. No son piezas impresas.
Como son tornillos mecánicos, es necesario tocar los orificios que los reciben.
Atentamente
Hello Olga
The part marked 1 is the output shaft of the geared motor of your choice.
The other parts are standard hardware. They are not printed parts.
As they are mechanical screws, it is necessary to tap the holes that receive them.
Best regards

Hola Olga
Simplemente usado "Coupleur_Moteur-arbre_BP_V1_Slic3r"
Esta es una pieza de "fusible" que se romperá si alguien intenta girar la turbina a mano o detiene el compresor de baja presión mientras el motor está funcionando. Proporcione una o dos piezas de repuesto para reparar en caso de exposición pública.
Por mi parte, la turbina está bajo una campana transparente cuando la expongo.
Hello Olga
Simply used "Coupleur_Moteur-arbre_BP_V1_Slic3r"
This is a "fuse" part that will break if someone tries to spin the turbine by hand or stop the low pressure compressor while the engine is running. So provide one or two spare parts to repair in case of public exposure.
For my part, the turbine is under transparent bell when I expose it.
Best regards
