Dual Propeller 3D printed 100 mm Electric Ducted Fan | 1700 KV Motor | Part 2

This is part 2 guys
Checkout the part 1 by clicking the below link :
Hello guys, I have designed and built a 100 mm Dual propeller ducted fan in this video and compared the thrust of two different propeller configurations. The ducted fan has a 96 mm diameter and is 3D Printed. I am using two DYS Series motors of 1700 Kv.
I have designed a new blade for it.
Check the maximum thrust obtained and use these results for your future projects.
Check out the video to check the thrust test of the motor and make one for you.

You're really good, thanks for your very methodical/scientific testing of edfs, something I have a big interest in.

[liamhamm]

A list of suggestions I would recommend is making the 2nd stage with a mor aggressive angle and maybe if you try a 3rd stage that’s even more aggressive with a housing that funnels in at the exhaust ever so slightly and adding a flare around the intake to increase the directing of the air in therefore increasing compression. You could also add a vein to direct airflow better in the initial stages I’d recommend looking up a variable state vein. I hope my recommendations helped increase the efficiency of your motor designs I love making new things and helping people do it

[hypeboy]

wow your setup is so clean and precisely made is systematic deserve million of subscribers making different things

[daletucker]

test needs to include external static pressure test..to determine the load on the motors. less thrust may be due to lack of air volume passing through... increase pipe size and check motor temp.... really enjoying your vids... thank you

[fazrulrusdi]

I truly admire your effort.. Perhaps you could start back to design the fan blade after having some looks into the fluid mechanics text book.. The rear fan will need to have higher pitch subject to the angular velocity of the airflow after pushed by the 1st stage.. The numbers of blade need to be unique number.. Anyway wish u all the best in designing the best edf for your needs.

Hi, I wanted to know if a 12, 000 battery (for all four) and 8 60A ESCs at maximum speed would be fine with four of these twin-engines.

Can you make a video to produce 2 kg or more thrust with suitable EDF and Propeller unit

[robertchongthu]

Hi. Love your design. Which of your edf 70 or 80 or 90 gives best results to produce 1 kg of thrust?

[dilbert]

Most imporant suggestion, make the fan housing two parts and put the fance in the middle immediately faceing each other instead of this far apart.
Second: the rear fan needs LESS angle od attack as the first. This is because the swirrl of the first cause an natural increase of the angle of attack for the second. So it needs less physicxal angle of attack.
Heino Dittmar did counter rotating fans in the late 90th as the canned motors of that time were so ineffective and have elaborate this already.
Got lost with more effective motors that the increase of effectivity of counter rotating fans got lost für simplicity of design with single fans.

Can you make an EDF that can match the sound of a jet engine. Eg: jetcat p300 or other hobby turbine engines.

[yerri]

Im no engineer, but it would interesting to see what 3 and/or 4 propellers would do to thrust. Theres no video out there that explains that.

[aalaal]

Hello.. TQ very much for the dual prop EDF lesson. If i wanna get at least 20kg (dual) sustaining thrust, what brushless motor specs and models do you recommend that i can buy within Asia?

Is the TMotor p60 kv170 good enough?

Can I also pay for your service to design ducts and propellers.. how to contact you?

[NavysSeaman]

How many miles can it cover when mounted on a jet drone and please what is the pros and cons

[Divyesh_Sinha]

Bro
Test your setup again with 2 80a esc and a higher C rated 4s LiPo
We wanna see it's full performance

[Cryptic_Chai]

How did you optimise the design of EDF? Have you done any calculations or research prior? If yes, can you share papers?

[Lucas_sGarage]

i thinkt that there is a realistic chance that you can make the 2nd stage angle more aggressive since the 1st stage already is acceleration the air, anyway, great video man

[Portondown]

Why the background music? Not necessary!

[sagarchitragar]

How many weight airplane ✈️ we can make using 64mm 3500kv EDF fan ?

[VALORANTDEVIL]

do the test for 1400kv bldc motor with 5045 propeller

[VALORANTDEVIL]

Is the 40a esc good you used in the racerstar thrust test please tell me bro.
