Well that was more complicated than i was expecting! Interesting
No ads, no silly intros and no intro talk, straight to busyness
Only shitty music in background… so yeah 😅
Add the funny voice and tone. Love it!
Anyone who has ever flown will have heard their CFI scream "MORE RIGHT RUDDER" and "CENTER THE BALL" for their entire first few flights. This is why.
Yep, I was awful on my first flight. But I’d say on my 5th flight I got good muscle memory on the rudder pedals. (I have a lot of flight sim experience so that might help)
Yep my first CFI would said “MORE RUDDER!” then my second CFI would sing it! 🎶 RUUDDAHHH! A little more ruddahh!!🎶
@@axio1208i assume with a british accent?
@@PatrickPeaseI'm picturing a Bostonian. 😂
Yawwwww
Afaik for some of these forces the correction is built into the airframe, like having a wing with a slightly higher angle of attack than the other. Its very slight tho, so pretty hard to notice
Btw, love your videos!
Ah, interesting. Thanks!
some historical aircraft like the Macchi C.202 countered the effect by making one wing longer than the other. The C.202's left wing is 21cm longer than the right.
I cant imagine designing an airplane with having to deal with so many factors
Now I will go to ksp 1 and will try rotate my motor this way😂
Try designing a helicopter.
@@toolbaggers this
Just remember even Bernard Pietenpol with just an 8th grade education could design an airplane from scratch in 1928! Just search his last name. There are lots of planes flying designed and or built by people who just take it a step at a time, do their homework, and keep at it.
Anything will fly with a big enough motor. An old truism from a long time model aircraft builder.
But these factors are well understood, and when designing a plane you can rely on a great many rules of thumb, including setting the thrust offset.
Whoever mixed the background audio was a genius.
It's not just mixed, it was custom made!
@@KnowArt Wow that's some intense dedication for a very short video
nope
Honestly I found it annoying but put up with it because the script and animation was great
Man this person is amazing at explaining stuff
thanks a lot :)
Maybe at youtube. But his tiktok sucks. He makes lots of tiktoks explaining simple obvious concepts in such unnecessarily confusing way it makes you feel like you were born yesterday. He was the first scientific-ish media creator I actually disliked in my 25 years of life
No wonder! I had a small RC plane with the propeller angled to one side. I thought it was due to damage 😂
Its a lot more critical on a model aircraft because its extremely difficult for modellers to add rudder as required remotely and they usually have much more power and torque relative to a full-scale.
@@dr_jaymz it was a 3 channel too, so the rudder was also the only way to control roll
@@tenseven1398 often you can mix rudder and aileron so they are coupled. One of my most fun models doesn't have a movable rudder, its very over powered so in a climb the only way to stop the yaw is to roll all the way up.
When I was a kid I was always wondering why my rc plane kept circling to the left even if i was going straight
It probably was because this only applies to full-scale planes
Thank you for making this super short and concise I really appreciate that
this video is just so well made?? i feel bad for thinking this channel is one of those content farm from seeing the logo. i really appreciate the sound design especially in this vid too. heck yeah fluid dynamics
I love this, straight to the point with excellent animations. 10/10
Weren't you listening? It's not straight, it's angled.
That's why I struggle in IL2 games to stay straight.
I wondered why my plane was diverting.
This is why I like counter or contra rotating propellers.
wont this just turn the airplane to the right instead of to the left?
@@thecaptain291No, contra-rotating propellers means the plane has two propellers, spinning in opposite directions.
I love how your videos are super well built and has some immersive sound effects!
that's not "just a fun fact", that's VERY USEFUL!!!
Such a complicated problem, with such a relatively simple solution. Wow. Learned something new today, already, and it’s only a quarter after 4am.
Thanks for explaining it without any fluff
The engine is sometimes mounted on an angle! Because the air spirals around the plane and pushes against the rutter, which would turn the airplane to the lrft. So to counteract this [Repeat from beginning] 😊
Good job buddy you watched the video
@@codrinmicusan446Good job buddy you're whiny
@@Espartanicathe fuck is the point in regurgitating the video, though?
@@theguy9208 It's this little thing called a joke, which flew over your heads.
You dont usuallybjust find videos like these on yt with low views and likes, so im add8ng myself to the roster, and i might recommend this channel. Its a good one!
thanks! that means a lot
Best video on the topic, great job. I never considered the gyroscopic effect before
So thats why i need five degrees of right rudder trim on my p-51 in dcs, thanks
Expected a slow paced video that spent long time explaining something that had simple answer so that one has to skip forward to see the actual cause thumbnail promised. Got a video that explained the thing in the first sentence, and dvelved deeper into other interesting subjecs. Great video! Thanks for not wasting viewers time even for a second!
Really nicely illustrated, animated, clear, and concise video!
Interesting, this is actually a whole lot more complicated than when I last tried to make a single engine prop plane in Kerbal Space program, where the primary source of torque was actually from the motor itself, and had basically nothing to do with the propellers.
I love the sound effects for some reason
Man you're packing knowledge! Thanks, Absolutely loving the way you deliver it!
Very nicely explained, both the dialog and the graphics.
Great explainer. This is so complicated and your way of explaining it is very entertaining.
Some designs not only offset the thrustline, they also offset the rudder, both in mount point and angle.
The Gyroscopic precession you mention is why the WW1 Sopwith Camel was both one of the hardest planes to fly, and also one of the most maneuverable. The engine cylinders spun with the propeller (a rotary engine with a fixed crank, not a radial where the cylinders are fixed and crank spins)
The added rotating mass made learning to fly it a real challenge, esp take off and landing. These engines had no throttle, controlling speed was done by "blipping" or switching the ignition completely off. The resulting torque reaction + centrifugal forces of cylinders and propeller caused the Gyroscopic precession that made joystick response totally counter intuitive, and changed depending on air speed. I think the Sopwith Camel took more pilots off the census due to handling errors than combat losses.
Great video! Str8 to the point, good animation, good explaining, you got me as a subscriber in no time. 👏🏻
This is why we have trims and trim tabs on the control surfaces in order to counter such forces without any significant change on the aircraft's overall structure
Not exactly..
Fantastic video, should be shown to all budding PPL pilots
The information density in this video is crazy.
explained beautifully :)
I love these videos, keep up the grate work man 🔥
thanks! I will
This video would benefit a lot from having numbers of a list of those factors. There are a lot!
thanks for the feedback :)
The visualization was top tier!
Nice explanation !
Short and to the point, nice work
Thanks
I second this. Most engineering channels (or any channel in general) would have made this a 10 minute video to take advantage of the algorithm but a short and quick answer is what a lot of us want most of the time. Small quick hits of dopamine lol
Very well explained! We call these the left turning tendencies (for hopefully obvious reasons).
just a small taste of how complicated aerodynamics can be aha, this is why the people that pioneered airplanes are such geniuses
Yo this is pretty cool and straight forward !
Well that was more interesting than i was expecting! Complicated
Can confirm, works in Flyout! Neat.
This feels moderately unhinged, but i enjoyed it. Liked & Subbed.
I believe the Sopwith Camel was rather famous/infamous for that. Not only its prop, but the entire weight, torque and inertia of its engine added to this. (rotary vs radial engines)
Thanks! I've always wondered why it points slightly to the left
Amazing Video. Please more of that
Thanks! It takes an eternity to make, so don't hold your breath. But more is to come
All Radio Controlled single engine airplanes models are designed with 1 to 2 deg of right thrust, just buy one and you’ll see that, even the rubber band free flight models, have that design feature.
Ive never heard of the engine being mounted off center before. Though on some old warbirds the vertical stabilizer is placed at a slight diagonal.
The video was really well made
On the c172 I flew, the rudder was off center, for the same reasons, so it’s either the rudder off the horizontal axis or the propeller
Well done thanks !
There's this new invention out now. Something called a "trim tab"! 😸😸
flight instructor here, well done!
Thanks!
I dont know why but going through all the various factors that turn the plane to the left reminds me of the "square hole" video.
"And what effect does that have on the plane?"
"That's right, it turns it to the left!"
hahaha
The four left turning tendencies of an aircraft... Pretty neat. All beginner pilots learn them.
Not only fixed wing, the Enstrom F28 also has an angled mast.
short and succinct! very nice
First Video i wtched this morning instatly subcribed!this was very interesting
Thanks a lot! That's great to hear
You deserve WAY more views
thanks! Working on it... haha
Nice education
oh wow youre so underrated
thanks
turn up to go right... reminds of something... classic.
That was amazing....just amazing.
Subbed!
welcome
I think the P in P-factor is for pitch, not propeller. It’s the difference in pitch between the descending blade and ascending blade caused by the angle of the relative wind.
I believe that you're correct.
Excellent!
Meanwhile in Germany:
Es ist was es ist.
**proceeds to create the Bf-109 which is atrocious when it touches the ground, but allowed many pilots to have great success**
Thanks. Now I know how to fly.
Holy crap! I had a biplane on KSP with this exact issue! I had to constantly compensate for the plane trying to go left. Wonder if that was the issue all along?
I love your narration voice lol.
Who needs an A&P
So this is the reason why my planes can't fly straight in warthunder
Radio controlled planes call it add side thrust when the engine is angles 1-2 degrees to the right.
Huh, I'm well aware of gyroscopic procession (give your kids gyroscopes!), but never thought about how it could affect flight on propeller planes!
Can you tell me in which software you make these videos and how can I learn please 🙏🙏
I use blender. TH-cam tutorials are great
@@KnowArt can you give me some channels that can i learn from them this style please 🙏🙏❤❤
Start with the donut tutorials and from there search specific things
That's why i like to fly by flapping my arm incredibly fast, it's a lot simpler
MS flight simulator has the physics down pretty well.
Wonderful. Loved this video. Short and to the point. You've just earned a subscriber
Awesome, thank you!
great thx
Man you left me with more questions than answers, at this point I don't even know hoe planes can fly 💀
Black magic
Yes fun facts!
A video on wake turbulance would be a good fallow up to this one. "why does a small aircraft need to wait so long before /landing/taking off after a large aircraft?"
oh, sounds interesting. How long are we talking?
@@KnowArt the video itself could be a shorts or maybe a minute long at most would be needed.
Or if you are asking about the delayed distance between aircraft. Well that gets tricky. A Cessna does produce wake turbulence but at such a little ammount that another aircraft of the same size or bigger can fly without much worry. However if you were to try and land a Cessna right after a jumbo jet you would likely end up being flipped all about.
The TH-cam channels 74gear, Mentoraviation, or CaptainJoe have great explanations of the subject matter that goes into a lot of detail.
Aircraft classifications get into the required safe fallowing distance depending on class of both aircraft.
Super cool!
Tfw the plane REALLY wants to go left.
The majority of the reaction is the torque, the others less so, but a rudder solves a multitude of aircraft design sins. Then a trim tab on the rudder solves the other problems the rudder causes. When in the cruise an aircraft is typically set up to fly straight without any input but very few do. So the trim tab is a bendable bit of metal that you can bend until it all flies straight. Then the next problem is that only works at one power setting....
Fantastic
very cool
I can't take credit for the existence of these facts, but thanks anyway!
I guess putting the prop at the back would solve some of the things shown here?
Ah yes, simulator mode in WarT hunder
When you kept crashing in interwar plane
And this is why the Wright brothers are the legit aviation pioneers.
These concepts were developed by them and not Santos Dumont or Arrow.
They knew what they were doing. The Wright flyer had counter-rotating propellers that cancelled out a lot of these factors.
Twin props: 😎
Gramercy!
I feel like this guy is forced to read the script in under a minute at a gun point.
hehe
Some airplanes are worse than others. Taildraggers are very finicky when the tail comes up due to gyroscopic procession. Older airplanes such as Stinson 108’s and Aeronca Chiefs have very disagreeable adverse yaw. Roll the yoke left the nose goes right while the wings stay level. The remedy to AY is to first use the rudder to begin the turn then use the ailerons to coordinate the turn. Cessna engineers solved this problem in their 150’s and later single engine aircraft by designing an aileron with a ridge on the bottom of leading edge that protrudes slightly below the underside of the wing providing increased drag to the wing in the direction of turn.
Conclusion: aerial flight is impossible.
So planes just really want to turn left. Does having a pusher help with this?
It hurts, but cool nonetheless
Where do I go to get this level of knowledge and explanation but 10X slower?
college :P but there are also some other channels out there that go a little slower. Jared Owen for example. Lesics too, although there's a huge variance in his quality in my opinion. And of course the classics that go a little more in depth. Real engineering, Steve Mould, practical engineering, MinutePhyscics, you name it
Than you might as well take a look at rotary engines (le Rhone/Gnome etc)
