I would assume NACA ducts also fell out of fashion for fighter aircraft due to the transition to supersonic speeds? I don't want to imagine what kind of weird expansion fans and shocks would would get with a NACA duct at those speeds.

[@mangeskulkarni]

Very nice and precise explanation! Cheers!

[@BSport320]

Glad it was helpful!

[@SRDmotorsports]

Loving this video so much! As aerodynamics have always been close to my heart…and Physics… Every engine or racecar project can always get better and or have improvements with things such as these! Thank you for this :)

[@SusedatLubo]

Howdy! Nice to bump into you here, researching aswell :D :D :D

[@BSport320]

Thanks for sharing!

[@Tuberuser187]

Nice video, I knew what/who NACA were but I was wrong about the ducts. I didn't know about the vortices, I just figured the widening shape of the duct was to accelerate the air as it entered into the car.

[@BSport320]

Glad I could help!

[@pike4625]

very nice! I always was thinking its just a design feature, very interesting.

[@LBG-cf8gu]

Great explanation for those of us mathematically challenged. Thanks for the upload.

[@VolkanTaninmis]

Best explanation in KZbin. Thank you.

[@BSport320]

Glad it was helpful!

[@ahmettaskn5687]

They are still used in aviation as air intake of PACK (Pneumatic Air Cycle Kit)s which are used to condition the air in airliners, inlet of B737's APU, vent surge tank inlets, ECU cooling duct inlets on engibe cowls etc.

[@th1nk_outside]

Can you explain in detail how they work when turned around? I know that they did it at Nascar for low pressure outlets when they found a loophole in the rules. But why exactly is this backwards form better for integration then a normal vent

[@randompalmtopgaming7541]

Love this content.. high quality, short and concise

[@PrinzAquatic]

NACA duct didn't die in aviation They're just used for other than cooling the engine, example are G91 YS, Multiple NACA duct around the cockpit area

[@ugrdncr]

i was wondering about this ducts last week and your video showed up. thank you

[@BSport320]

Glad I could help!

[@noampitlik2332]

Hey, that was good.

[@officialWWM]

Much more hi tec than I would have ever thought!

[@iugey]

I love this video. This is a GOOD video.

[@BSport320]

Glad you like it!

[@mattrowland473]

Found to be inefficient in experiments on the even earlier Lockheed P-80 shooting star, first US operational fighter jet. fun facts

[@tiagobelo4965]

What did they end up using instead of it?

[@sim.frischh9781]

That was highly educative, thanks for this video. Because i have always wondered whether these cuts wouldn´t lead to a high drag on a car at high speeds.

[@brentfulleroreal9708]

Thanks for this! Keep it up B Sport! :)

[@arnedevriese339]

Nice video, keep them coming! :) I would be very interested in the aim of fender vents on the Porsche Taycan and the Mercedes eqxx.

[@stickman-1]

Thank you for the video. It's very helpful.

[@BSport320]

Glad it was helpful!

[@ruandurand3971]

I am currently using a hybrid design at work on an aircraft where you try and compromise between the naca duct and a pitot duct. As the naca duct does not supply enough ram air pressure for the internal cooling but reduces the drag of a fully protruding pitot duct.

[@TricksterJ97]

I once designed a hybrid for use as a turbine engine inlet. A pitot type would have been best, but clearance in the launcher wouldn’t allow it. It worked very well.

[@CreamAle]

Hilarious, i was just thinking i wonder if any of the previous f1 engineers have a video about NACA ducts, sure enough b has one.

[@andrewrobertson9450]

Thank you for your efforts

[@pareshprajapati7916]

Thank you sir 🇮🇳🙏

[@silverspiderpig5]

Super cool always looked at these and never thought twice, the shape always made sense but I never thought why

[@gafrers]

Wonderful

[@firsteg95]

Always wondered about these!

[@JayCee_1014]

Great video thanks you

[@wfomph1435]

thanx

[@car_ventures]

2nd gen Z28 Camaro hood makes sense now

[@mxcollin95]

Awesome video…well done.

[@BSport320]

Thanks for the visit

[@aaronpitts2762]

Hi great video. We need proof of what these parts are actually doing. Ive got a question if you don't mind? What sytle ram air intake would you recommend for a k car hatchback from Japan? They have a very different body shape to a normal hatchback and was wondering if you would have any advice on this? Thanks Aaron

[@mosca3289]

Concise!

[@RB26N]

Good one, always wondered how they worked. A question if you don't mind, why GT3/GTE race cars are much more pitch sensitve than F1 cars ? my logic is that GT3/GTE cars run quite high ride height , so to gain highest downforce level manufacturer make them peaky. so the car gain downforce rapidly as ride height decreases via aero load.

[@BSport320]

Simple answer is because GT3 cars have a flat floor with a splitter at the front. Formula cars have a front wing and the flat floor only starts underneath the driver. But as always, it also highly depends on the design of the cars...

[@RB26N]

@@BSport320 Very good explaination. thank you very much.

[@indopleaser]

video suggestion: flying buttress like Ferrari 599. have seen this on other cars too. would make a good video. Thanks

[@SimaVG]

And as far as I know, NACA inlets are valuable because of their aerodynamical properties to prevent formation of ice. Its made for planes. No need for anti ice system

[@Normally_aspirated]

This is what youtube is about

[@fernandezadrian6357]

Is a similar principal at play with Ferraris F1-75s outlets? That have a slight taper in towards the end? (I'm taking about their top mounted sidepod air outlets)

[@chillville2938]

How do I buy your naca ducts? I'm having issues finding you on my eBay app, in English that is,

[@stevenjohnson7745]

I need a custom scoop for a intercooler on my plane. Can you design one?

[@BSport320]

Sure, you can contact me on my homepage.

[@stevenjohnson7745]

@@BSport320 not sure how to do that

[@spacecase13]

These need to be sold small, and in bulk, just so I can fill my pockets with NACA Ducts.

[@RCmaniac667]

So ram air intake is still better and NACA ducts are for pure aesthetics?

[@BSport320]

Depends on what you want. Ram air ducts for high pressure but with drag penalty, NACA duct for low drag with a bit less intake pressure.

[@ruandurand3971]

It all depends on how much airflow you need to be ducted. High stagnation pressure = pitot duct. Low stagnation pressure = naca duct. But you do get hybrid designs that is a combination of the 2 to find a nice middle ground of drag reduction and stagnation pressure.
