Gliders are airplanes heavier than air that can be kept in flight without an engine. How can you fly without an engine? That is what is explained in this video in addition to several curiosities about these aircraft.
According to Wikipedia a glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines for extending their flight when necessary by sustaining the altitude (normally a sailplane is on a continuously descending slope) with some being powerful enough to take off self-launch.

Am I the only person who thinks we lost something when we lost the cheerful - sometimes quite stunning - colour schemes of the old gliders? Boats are GRP and they're turned out in range of colours. Its all in the Gel coat anyway. Hell - Its actually easier to recognise at a tiny glance something which is day-glo Pink or Orange, or even gloss black isn't a cloud. And if its near you that *has* to matter. So why has it changed?
To avoid uv light damage over time. White is the color of choice to make your expensive glider last longer.
@@Joyplanes in that case they should just keep the top half white
@@ShayBowskill a glider doesn't fly straight for 100% of the time. It's circling in thermals and because of that it wouldn't have consistent wear when the top half is white and the bottom half isn't. In addition the sun is moving as well, you will not always get sun from the top, you usually take off in the morning and land in the afternoon or evening.
That is true, but we may be getting back to the days of colourful gliders. Schleicher have developed certified colourful paints for their ASG 32, and that may just be a start.
@@otsokivivuori7726 Just when we were all starting to suppse good news was just something that happened long ago. This side of winning the lottery I probably won't be buying an new ASG 32. But the thought they'll be out there is kind of heart warming.

How to make gliders go supersonic: step 1, approach a strong tornado
As a glider pilot I am constantly trying to explain it to friends etc. A great video that explains the basics in a simple clear narrative, even includes “wave” explanation which I never attempt to try and explain to non pilots.
How much does this glider cost?
@@Gabriel-pt6tq depends on a lot of factors, such as its materials It can be (most likely) wood or composite Wood glidrs such as a ask13 can be quite cheap, a few thousands € (usually 10k+) Composite ones can be sometimes hundred thousand(s)
(btw it might not be exactly *composite* materials, i didn't learn it in English so it might be a different name)
Did you get questions like "what if the wind stops?"? it will will get pretty boring 😁
@@basslachnith865 Wind ? what has to do with it ?
It's fantastic how with all the aviation technology that has been developed over the last 2 centuries, the best way to monitor relative airflow in a glider is still to just tape a piece of string to the canopy.
And gliders don't explode when crashed which is a good thing
It's not really that surprising if you delve more into aviation development, most of aviation seems to focus on the least techy way to get something into the air and keep it there without fail
@@kayan5754 Crash, explode ? Oh we don't do that . It's not recommended by the manufactures ! 🤪
sailboats use the same in the sails... a few strings they must be horizontal to correct the best position of the sail respect to the wind
the simplier, the best.

How much it cost to learn it?
One of the best videos I've ever watched on KZhead, felt like I should share this to all of my contacts! Thank you!
Thanks for the nice graphics and demos. I flew gliders for a couple of years in N California. Ridge lift, thermal and occasional mountain wave. Loved it. I also built and flew RC Gliders. All fun!
Belive me: A start from a winch is quite an experience. I grew up with two PPL pilots and flew sometimes by myself when in the air. 1. When the thing starts and your head is not in the back of you seat, it will smash in the back of you seat. it hurts!!! xD 2. If the plane starts climbing, it does not do that softly. it just feels like you're in a rocket launch (up to 2.5g) straight up in the air. 3. because winch starts ar tipically on a mountain plateau - even if you're just 400m above the airfield - your first view is down the whole valley - and that can be fucking scary! Because what you're seeing is the hight to the airfield (400m) + the whole hight of the mountain plateau (X) So just 30 seconds after smashing your head and having a rocket start, you find yourself in a absolutely silent, 2 cm thick nutshell in 1.400m above the ground... I LOVE IT! :D That moment when the pilot releases the rope...everything turns silent and you're just sitting in the air, free to do what you want (for a few minutes)
Shush
sos scareeee
"for a few minutes"? Or several hours - depending on the weather ...
@@EneriGiilaan - Yeah, right? I've looked at a glider's flight log book today. Most of those trips were between 4 and 5 hours
Yes, the extreme angle of attack and rate of progress can be roughly assessed by watching winch ups from the airfield but nothing prepared me for the roar of the rushing air as you butcher your way through it in the first few seconds. You think ''there's something desperately wrong here, it's supposed to be serene and relaxing in a glider''...and then... you release.
I flew in one when stationed in Germany during the mid 1980s. They had a Chevy v8 at the end of the field, approx. 700 feet away. It had a rope winch to launch the bird into the sky. Believe me that is some kind of launch! Dead start to heart attack, what feeling. It cost me approximately 10 dollars for 20 minutes. Pure quiet, except for the slight wind. Soaring up and looking for updrafts, etc. loved it, loved Germany and other surrounding countries to travel.
Henauder Titzauf Dang. 700 feet is pretty short for a winch lol. Usually they’re at least 2000 feet long. The one at my field is 4500
@Desmond Bagley Yes. Sailplane training is done dual control
@@AN2Felllla Yeah 700ft is very short, I wonder what height they would get on launch. Ours are 4500-5000ft long
@@somelokyguy6466 the entire earth ? :V
@Desmond Bagley Most glider clubs, and business's which do training have 2 seat gliders. The most common is a Grob 103 but there are others as well. Once you get your training typically you fly in a single seat glider. The reason is the single seat has shorter wings so it can be rigged by one person. Which means removing the glider from a trailer and attaching the wings. Lot of times you find passengers like Wives or GF find it boring or get tired of doing tight turns in a thermal. It's fun take up family for an hour or so at a time maybe do a few aerobatics. You would not want to own a 2 seat glider but only fly it single seat typically they are only used for non training rides, and training. I own a single seat but if my wife wants to go up for a few hours I rent a 2 seat model cost is $60 an hour. If you live near a glider club that is best way to go because cost to rent the gliders is cheaper then glider business's.The hobby isn't cheap about 8-10k get a license if you rent, and 20k min to buy a used decent single seat glider. You can rent usually $40-60 an hour, or join a club which is the best way to go.
Your article on gliders was in- formative . I appreciated your way of narrating and making learning simple.
My first real glider flight was so great, I'd only flown in prop driven planes etc. and it was so silent and peaceful by comparison. Learnt to thermal on first flight. Being towed into the air is kind of a strange experience, and when you land you are so low to the ground on the runway...
post or didnt happen
next time you get to fly in a glider, try to get a winch launch. These are very impressive too
6:23 you don't have to put weight in the wings. Water ballast is used when the weather is extremely good so you can fly faster. It essentially shifts the entire polarity of the glider to higher speeds, so you have higher efficiency at higher speeds, the drawback is that it is harder to gain altitude. This is however not really common practice as it is rarely practical for most pilots, many high performance planes with engines are already heavy enough so water is not used that often. cheers!
Great detailing on that. Thank you.
Why do gliders gain altitude? It is because they want to gain energy, and that increase in altitude gives them more potential energy, which means they can stay up for longer. Gliders don't really want to fly above 10,000 feet because they are not pressurised and the oxygen in the air is too thin for the pilot. Adding water to a glider adds mass, and the potential energy the aircraft has is equal to mgh, mass x height x gravity. So you may not gain as much height with the extra water mass but you are still gaining potential energy. With water onboard, for the same increase increase in potential energy, you gain less height, so when you finally reach 10,000 feet the aircraft is carrying a lot more potential energy than without the water. So you are maximising how much potential energy the aircraft can have, enabling you to remain airborne for longer before having to land out or to find another thermal.
@Dean G, you are right when it comes to energy, but we glider pilots are loading water to our wings to fly at higher speeds, which brings more points in competitons. Also we are able to fly higher as 10.000 ft, as most of the modern glider are having build in space for oxygen bottles.
I got my glider pilot license this year and it is by far the most fun i have ever had! I fly the sgs 233-a wich admittedly isnt the prettiest but lots of fun.
Air cadets? I know that the ACGP is one of the largest users of the 2-33a. It is also how I got my license this summer.
Gotta love the truck that is the sweitzer 233. I started on blanik L-23s and transfered to 233s. You can land that schoolbus however you want lol
@@zacharytaylor190 yeah!

@@ryanestes7331 Blaniks are really cool, my dad flew them, and I might get my license on one too.
I was very surprised to see that animation at 2:36 that's exactly the place where I live right now and learn paragliding... Didn't expect that
I recently tried gliding with these planes. And it was amazing!!! I really am thinking of trying this as a hobby
Go for it!
ive done 11 solon flighta now at 15, its a great hobby, really exciting and amazing every flight, tb I always feel safer by myself anyways
It isnt a cheap hobby... flying small prop planes would be cheaper. You can buy a good used prop plane for under 20k the only gliders you are getting for that price arent going to be good. Then with the glider you have to pay somebody else to tow you up which isnt cheap. This isnt a hobby you do on a whim.
Happy new year 2020 to all!! This year there will be more videos like this.
Very nice video, you got a new sub! (Español?)
Same to you sir 😊😊
Man, this aged terribly
Lol and happy 2021 to all. Lets pretend 2020 didnt happen
This exactly what I was looking for, thank you for easy explanation, with best graphics Thanks for great efforts
Really great content and in addition to that, the animations, editing elaboration of several aspects, everything is really brilliant and perfectly done!
A video well done. Taking lessons to become a glider pilot. It's an amazing feeling.
That really is one of the best introduction to gliders video ever made, well done!
I love finding other youtubers on other projects, Lemminos voice is instantly recognizable. Love the content.
This is not Lemmino my dude.
Also applicable to paragliding and hang gliding, thank you for this!
The first time I flew in a glider was at a California City airshow. They were giving glider rides, around 1984. The thermals off the Mojave desert and the Tehachapi mountains are some of the best in the state's. I've been flying since 1982. When we got our first airplane (N51305).
I did a glider flight in Germany on a tow winch. Truly an awesome experience
How long did u stay in air?
@@metekavruk_Alanya Probably 5-10 minutes
Too bad you didn't nosedive into the autobahn...
@@Megasigggg pfff, jea, thats all pilots wants every time in every case do to...
@@metekavruk_Alanya It depends on the conditions on the day . Off a winch I have stayed up for 3 hours . Only came down when I needed the bathroom .

Thank you. You answered so many questions I had and some I didn’t know I had. Well thought out and well explained. Masterful video.
KZhead is being recommending this video for a month!! Today I decided it’s time to watch it! Good job 👏
Gliders use 'the force' and all glider pilots are Jedis. The End. ;)

Damn right
Especially with the R2D2 sound around you at all times in the glider!
Yep. Glider pilots are lost without a fvcking vario. Every time on 123.4 when the wind is blowing a different direction than normal: “boop boop boopboop VER IST DA LIFT? BOOPBOOP boop boop.... boop”
Fabulous video and great explanations. Thanks for your effort. We are using this to introduce people to gliding here in Australia!
Video animation and demonstration was excellent ... Because of this, I have watched whole video curiously. Great work
Good explanation. The narrative style with graphics and detailed content put together and explained in simple manner is indeed nice. Thank you.
this episode of real engineering... wait
Hahaha I know
I.... Kind of thought that too but that just means its good
Great video! You put so much time and thought into this. I really like it.
Full of practical and useful "knowhows" on the pure joy of flying.
Gliders are so elegantly simple at a basic levels whilst simultaneously very clever and cutting edge in design and manufacturing. They're a lot like birds, to the point where it makes you wonder how it is that powered aircraft appeared and proliferated sooner than gliders themselves
Very accurate, and superb presentation. Thanks for this, and best regards from a (passive) glider pilot!
This was such a good video!! I learned a lot from it, very well made!
This is dedication. Loved it every second!
Lots of knowledge. Thank you. Can't wait for MSFS to get proper glider support.
Greatly explained glider' ability to gain altitude, as I was always curious how its basic flying mechanics works.
Once you get into wave , it's like someone lit a rocket on the tail . It goes up at a fantastic rate !
thanks a ton. it was clearly explained with animations that I will never forget it the basic concept of Gliders. kuddos
𝓣𝓱𝓪𝓷𝓴𝓼 𝓪 𝓽𝓸𝓷
I’m very happy to find your channel. Great explanation !
Those things have such a cool design, when I was younger I never thought those would be engineless
When I was younger I used to glide in Kent. We normally launched by winch as the field was on top of a ridge. We often used thermals set off by bonfires in the gardens in the local village. It always amazed me how burning a few leaves would release enough energy to lift an aircraft several thousand feet!
I used to fly from the same field. Cross country tasks were often saved by stubble fires lit by farmers, until the practice of burning stubble was made illegal due to air pollution.
Best thing in the world. Flying as a passenger is cool but just staying up there for 4 hours by yourself... thats another story
or 7 hours...
Well you can make preroute the plane to take a certain route that will allow you to land earlier.
been there done that

hello! Thank you for that video. I'm currently studying Aeronautical Engineering and I'm really learning a lot from your videos. Keep up the good work.

Take up model aircraft, you will learn (the hard way) but you will actually learn, that way.
@@Justwantahover Quite true... just don't take the lazy "Almost ready to fly" or "Ready to fly" approach; do it the RIGHT WAY: Learn to build from kits and then from plans.

Gliders are my favorite aircraft, they are so aerodynamic and beautiful to look at in flight.
I'd love to take a glider flight one day. I find them to be alluring in their operation and aesthetically pleasing. My flying models reflect those same attributes.
Are you from Germany ? or the Netherlands or Belgium I am a glider Pilot and can take passengers
Please, please do so , it's some thing you will remember for the rest of your life . The view is fantastic, from wing tip to wing tip . Not like flying in a airliner or small power plane !
You can just say that you have, like most of the people in here.
This is the best explanation video of gliders on YT. Trust me, I've been searching for quite some time.
I took a ride in one near redding, CA. so quiet, so peaceful. breath taking ride.
Great video! Extremely well made!
Good video but I would like to point out that weight does not affect the glide ratio. The best glide speed increases with more weight but the glide ratio remains the same.
Amazing explanation who don't know what is happening👍
Best glider informational video mate keep it up
Thank you so much for this in-depth video, it was perfect for me as a newcomer.
the answer: Magic
*majik*
Thank you now I do not have to watch the video
Wow im a magician then
Yeah, it's magic if this was an isekai story but it's obviously n..... Wait a minute, actually, that may not a bad idea if someone wrote an isekai story about making a functioning gliders using methods available to them with a little bit of magic twist on it. It would be a fun story if it was executed right.
Science/Engineering = Magic, so you're not too far off.
So, they are flying longboards.
Seems like the chillest way to fly
Great work creating this video, excellent animations and explanations.
Awesome! Thank you! Cheers from Brasil, Na Base Gliding!

Except the omission of the critical process of exchange of potential energy to kinetic energy and back again. You studied aeronautics and you did not notice the omission?
Thank you Sir, for your nice presentation on glider planes
Very well explained. Thxs
Gliders are also my favourite Because of its pure beauty
This is such a clever plane!! at first I thought it was a lie, I thought there was no way for a plane to fly without an engine, but you opend up my eyes ^.^ its a shame this technology hasn't been widely used for another purposes yet.

Why would it be a lie? Even the hang gliding distance record is 764km....
@@iforce2d Let's say I was just thinking completly inside of the box XD
Yes the video is excellent, except the vario sound @9:09 for -100ft/min sounds more like -500 ft/min ( -2,5 m/s) ;) In fact the U-2 spyplane was a glider with Jet engine. Using thermals for commercial Transportation is not (YET) feasable because of travel speed and the dependance of "good" weather because you need the sun to heat the ground and therefore the air mass directly above it to get thermal lift. In wintertimes it wouldn´t work because of lack of sunny days, and the lower angle of the sun, therefore lesser heating the ground, and sometimes you even have snow with a higher albedo (reflecting the sun rays). But theres another theory (in fact not a theory anymore) of dynamic soaring, using the different windspeeds (wind shear) in different air layers (e.g. Albatross use this form of soaring above the ocean waves).
@@iforce2d Believe it or not a French man flew across the English channel from France to England . I don't think he intended to do so . He had no papers with him when he landed . So he got in some hot water with the authorities .
Awesome video! Thank you for your hard work!
Amazing Video!! Honestly I had no idea how gliders worked and I know a so much about airplanes, Thank you.
most beautiful and fascinating Sport!
This is very good, I would like to add that thermals tend to come in many shapes and sizes. Thermals can also be initiated by ridge lift.
@Jack Casey Thermals are hot air rising yes, but you misunderstood my comment. How does hot air begin rising in the firstplace? You should try gliding (after quarentine), you will feel it for yourself. ^_^ If everything was flat, heated the same, no wind, no cloads, the potenial is there, but thermals won't start in any perticular spot, if at all. As there are no initiators. If you have a bonfire, concrete structure, etc. that cause a localised difference in the potenial, then a thermal will start because of those disturbances. If wind has to go up over a large structure, or hill, it can disturb the air and start a thermal. Perhaps me saying: 'Thermals can be initiated by ridge lift' was the wrong term of phrase, I hope you understand what I mean now.
Great explanation! Thank you!
Just came back from watching glider that literally floating due to getting stuck above the mountain air. This video explanation make more sense after watching that.
I too like gliders so much .They are so elegant and graceful in the air
I did not know that I wanted to see this content. Thanks!
I used to fly the Grob 109b (Grob, not Messerschmitt!), which is a 2 seat self-propelled motor glider. Very versatile as you could fly it as a regular powered aircraft but also feather the prop and operate as a glider with a decent 1:28 glide ratio. Gliding is fun but even better with a friend in the side seat!

@@PrimoPete but it has to land, very soon. You're dead then, unless you are made of luck and the thermals carry you to the other part of the world
@@aydict True. I'm assuming you either have a cluster of communities in a given area hence a glider would be helpful to travel between them or if you are traveling long distances, you're doing it by taking stops through the country side.
