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.

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.

[@MechNinja]

You have to calculate the amount of amp each motor then you can calculate the time of flight using online calculator

[@liamhamm8591]

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

[@dilbert0815]

EDF will not realy 'compress', its more about flow. 3rd stage ist not realy effective, counter rotating IS. Thats as counter rotating it serving as a better statur vanes that have to be there to remove the swirl in the flow.

[@dilbert0815]

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.

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

[@MechNinja]

[@daletucker1629]

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

[@MechNinja]

Thankyou so much for your suggestion....I will definitely look into it...I am working on a more precise rig and will also include air speed....Do check my new videos they are so informative.... And thankyou for watching and don't forget to subscribe 😊😊😊😊

[@NavysSeaman]

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

[@MechNinja]

You can go with 70 mm EDF it has more thrust...check my videos for it And time of flight depends on the battery you are using.

[@NavysSeaman]

@@MechNinja how about two 12 v/Ah battery

[@duracoatsales1273]

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

[@MechNinja]

Yes sir i am working on it...I am not sure when I will design a 2 Kg EDF....but i am sure that all the coming videos have upgrades of the previous one.... This is what this channel is all about....about research and designing... Thankyou for watching the video and don't forget to subscribe 😊☺️😊☺️

[@fazrulrusdi3709]

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.

[@MechNinja]

Thankyou so much for giving your valuable information...i will definitely increase the pitch in my upcoming videos.. Don't forget to subscribe 😊😊😊😊

[@deepakjha8719]

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

[@MechNinja]

Well if you here it's sound..then it's similar to jetcat p300.... The main difference is that, EDf uses only a single fan blade but jetcat p3000 uses multiple blades including a compressor and turbine hence the sound is different.... Do one thing....chech my mini turbine engine video....it's a jetcat model and produces same sound. And thankyou for watching and don't forget to subscribe 😊😊😊😊

[@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

[@MechNinja]

I will soon upload the full test bro... Thankyou for watching and don't forget to subscribe so that you don't miss any video 😅😅

[@aalaal171]

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?

[@MechNinja]

Thankyou for your watching the video.... Well 20kg is too much thrust for an electric EDF....And TMotor p60 is designed for propellers not for EDF, it won't give much thrust in duct...EDF motors are different..... Well regarding the design....mail watsapp me at [phone]

[@Cryptic_Chai]

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

[@MechNinja]

Well I have not researched it....But I had made it identical to the one I bought from china....Both the propellers are almost identical.....

[@Cryptic_Chai]

@@MechNinja thankyou for replying! You made world a better place. 😊

[@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

[@MechNinja]

Thankyou so much for your suggestion and I will definitely do it... Actually so many people had told me about it and I am working on it.... Thankyou so much and don't forget to subscribe 😊😊 😊😊😊

OR SPIN IT FASTER ....HIGHER KV FOR MORE RPM IN THE 2 ND STAGE ..

I like it

[@yerri5567]

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.

[@MechNinja]

Well it will increase the pressure at the end. You can watch assembly video of any jet engine.

[@yerri5567]

@@MechNinja Pressure as in thrust? If it increases thrust then why is there no ducted fan with 3+ propellers? Jet engine is different as the function of the multi stage propellers are for something else so cant compare like that

[@VALORANTDEVIL]

do the test for 1400kv bldc motor with 5045 propeller

[@MechNinja]

It will be of no use.....because 5 inch propeller requires atleast a minimum 2200 kv motor

[@sagarchitragar3190]

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

[@MechNinja]

Sir it totally depends on the thrust as well as the design of your plane. We cannot just decide any number of thrust. We have to do the calculations.....If you could let me know the thrust then I can give you an idea.

you could hav used better esc and full throttle
