HOW DO airplanes REDUCE DRAG? Explained by CAPTAIN JOE

[@mohammedayaankhazi8970]

Answer: Gliders ? they have highest Aspect Ratio wings which increases wing span and to reduce the affect of wing tip vortices

[@mohammedayaankhazi8970]

which then reduces the downwash and the induced velocity hence the induced drag

[@TheUnsungHeroes]

Bro u literally stole the answer out of my mouth 😂😅

[@TheUnsungHeroes]

I was late lol

[@largo6644]

I agree with gliders !!!

[@mohammedayaankhazi8970]

@@TheUnsungHeroes more like learnt it from my Aerodynamics teacher when he was teaching lift distribution over Finite wings.

[@Horstroad]

7:38 I think this is just a test setup. I assume the final design will be located where the beacon light has always been. A test setup in a cabin window makes it easier accessible for monitoring and altering the setup.

[@PrideCraft]

Fr tho if they go ahead with this, won't the light be disturbing the passengers and anyone sitting in a seat won't want a huge box in thier face anyway

[@FriesyRider]

Hi Joe. You even mentioned the rivet heads as source of drag, important point which many people wouldn't think about. Me as an aeronautical engineer I missed the interference drag which can be reduced by rounding the edges between vertical fin and fuselage for example. I like your explanations and attitude very much. Regards from Hungary

[@andrewwmacfadyen6958]

30 Years back I worked on project testing the gains from using "shark skin" Riblet Film in the cascade wind tunnel at the Institute von Karman near Waterloo Belgium.

[@adb012]

Captain Joe, you missed what is perhaps the biggest drag-saving tool: Long wingspan (which, for a given wing area, can be translated as high aspect ratio). You mentioned the wingtip devices all of which work by increasing the effective aerodynamic span of the wing, and you forgot about the span of the wing itself.

[@krismoff5749]

Also, cleaning the aircraft. bugs and dirt gather over time, and is bad for the airflow. Good video!

[@adilazak4305]

Parasite drag right

[@zain786ification]

@@adilazak4305 no , parasitic drag is the drag induced by the lift itself

[@adilazak4305]

@@zain786ification no parasite drags can be divided in three sections; skin friction, interference and form here its an examole of skin friction

[@Avio033]

To answer the quiz, I think it's non of the winglets you stated in your video, but the answer is the entire wing profile of the Dreamliner. The whole wing curves up once the weight of the aircraft "hangs" on the wings, plus the fact that the wingtips end in a perfect point. All this ends up making all the air flow naturally towards the tips, end leaving the tips with absolute minimal drag.

[@musmuk5350]

Hi Joe, the antenna displayed at 6:25 is not a wifi antenna. It's a satcom antenna, such as Ka band or older SBB antennae. The connectivity devices (wireless access point and network management hardware) are mounted inside the aircraft.

[@madvlad1]

I think Joe's referring to them as the antennae that deliver the satellite internet connectivity to the WiFi system as opposed to them being the actual WiFi hotspots. But yes, you are correct.

[@lylerodericks]

Hey why don't you want to collaborate with mentour pilot?

Captain Joe! Last month I purchased the scaled B747 replica model with your custom livery, and it came in the mail today. I haven't had time to put it together yet, but I am definitely looking forward to it. I also want to thank you once again for creating such a wonderfully-informative and -understandable channel for all of us. o7

[@Rafael_Yemane]

Thank you captain Joe..that means to reduces drag because there is a more streamlined shape and there is less frontal area?

[@poland0017]

Thank you very much for posting I hope you enjoy you’re evening and your book is amazing

[@alexandervongaumond4888]

Very good intel in regard to the saving issue! Its very important for who ever aspires to a career in aviation to understand that fuel saving is a big issue! Cheers!

[@onebigflappyboi8276]

3:30: I believe it will be the Boeing 787 Dreamliner because of the wings flexibly therefore less wake turbulence. And because of it's streamlined body it also reduces drag.

[@gasviation9077]

i think the answer is some sort of cessna 172 shaped like plane

[@dingusmann3003]

Fun fact: the cars of the primarily american motorsport NASCAR (which stands for the National Association of Stock Car Auto Racing) which falls under the broader curtain of stock car racing (even though the cars arent stock anymore) use NACA ducts for the purpose of aiding with cooling off the driver as stock cars dont have AC as their purpose built race cars and temperature is typically 30-40 degrees F higher than outside air temperature, so if the temperature outside is 60 degrees F, it's normally about 90-100 degrees inside the car

[@b4ufly-thecitizenofthesky475]

well done Joe! Amazing explanation as usual.

[@LtNduati]

3:30 Based on my diehard beating heart for F1 and my aviation knowledge, I'd assume the answer to least induced drag is something that would be flat and wide with an even progression like how a DRS wing on the rear of an F1 car opens up to reduce drag an increase speed or how a low downforce rear wing is usually shallow flat and has very few little curves in general. So a straight wing that's uniform across the chord to the wingtip with no wing fences or tips, similar to a glider, or a swept-wing aircraft when the wings are fully out like an F111, F14 in take-off wing configuration minus any flaps or slats (if applicable)

[@hazikaiyan5903]

[@sugardidilookoverthere2243]

For me personally, the Boeing 737 MAX has one of the best designs in the tip of its semi-wing; since by separating the winglet itself into two, the drag effect is lower and consequently its performance is up to 16% less in fuel consumption, making it one of the most environmentally friendly single-aisle airplanes. Greetings Captain Joe

[@IBo99608]

Constantly being grounded helps with fuel consumption as well. All that blood of the people that were murdered by boeing do contaminate the ground tho.

[@brokenboi3351]

Hey Joe Could you please do a quick video on flight plans? Like how do pilots when to turn where when they're cruising so that they actually reach their destination? Also, do ATC communications happen when they're cruising? Thanks very much ♥️

6:45 Ok so if you watched Downfall against Boeing basically a Boeing 737MAX 8 had something wrong the Mcase which is the 2nd arrow down basically controls the pitch of the airplane and the angle of attack if you it to high it will do a vertically straight down so yeah

[@bhargabmishra7804]

The least induced drag along with vortex windage is achieved by ragged wingtip design usually found on Boeing 787 and 747-8i versions.

[@jouniairplanevideos]

Especialy at longhaul flights. For shorthaul flights Blended or Split Scimmitar Winglet are a better option. Or redesign the racket winglets

1:06 "modern fuselages are rounded or almost sort of pointy in the nose area." Round noses are most streamlined for subsonic speeds while pointy noses are most streamlines for transonic/supersonic speeds, everyone knows that.

ANSWER - GLIDERS AS OF I KNOW ABOUT AVIATION ( ME 13 YRS OLD) WAKE TURBULANCES IS CREATED DEPENDING ON THE Weight of THE PLANE AND THE GLIDERS ARE VERY LIGHT AND THE ANGLE OF ATTACK IS NOT MUCH IN THE GLIDERS (CORRECT IF I AM WRONG JOE) GOOD DAY

Hi Joe, Surely the wi-fi antennas will be inside the cabin. The large antenna in the topside of the fuselage that you are calling "wi-fi" looks like the satellite internet link. They may be parts of the same wider system but they are not the same thing. Yes i know I shouldn't call you Shirley.

[@mikee2]

When you retire or maybe as an extra job, seek out either F-1 or Indy race teams and give them some techy stuff on wind resistance. They are constantly looking for ways to make their cars more efficient. Maybe you might be elevated to driver status.

[@c123bthunderpig]

Mike, excellent point, race car drivers are looking to push the car down as much as possible to maintain surface contact, Capt Joe would definitively be able to cross over and help them do that.

[@igorpestun8703]

It made me remember our old square vehicle with additional on-roof trunk, which produced similar to turbine whistle on high speed, and all what we saved was brakes, because of drug😄

[@tsky2983]

Your book is awesome :) The cold shower nearly killed me but it was fun

[@fdls59]

Serious question, when the military does huge drops of multiple vehicles, equipment, and other heavy stuff from the back/aft of the aircraft or when fire planes drop their water/extinguishing agents does that have a major impact on the aircraft? You would think that the quick loss of weight would cause an elevator effect (or whatever the scientific term is) causing the plane to pitch upward quickly. Does this happen, and how do the pilots prepare or recover from such an effect?

[@sagarsrivastava3549]

Uhh I can't exactly tell the model type but I'm guessing that since wake turbulence and induced drag are related to wingspan and wing shape, probably jets with small wingspan and elliptical wings produce smaller induced drag (Just a guess, not too sure 😅😅)

Evening Captain Joe, could you please advice me, if you have uploaded any video, explaining the difference, between ground speed and true air speed, of an aircraft ??

[@ZK-APA]

True airspeed is the speed of the aircraft with respect to air, whereas groundspeed is the speed with respect to ground (ie distance/time) An easier way to understand the concept is someone running on a treadmill. The speed the treadmill shows is like your true airspeed. But your groundspeed is your speed with respect to ground, which in this case is zero (as physical distance travelled is zero)
