I do not own any of these video's, I just made this compilation to entertain you. Thanks to the original uploaders, fly safe. See my other compilation. ru-vid.com?o=U&vide...
actually soaring planes are pretty much unlockable for fox 2 and perhaps because of thier slow speed even really tough targets for fox 3 or fox 1 type of missiles. (Latter because todays radars are optimized to lock onto fast moving metallic objects
Gliding is the best hobby there is in the world. If your wife isnt flying you have your weekend off from her. Take your tent or van with you, dissapear on friday night, meet all the other guys, enjoy some beer and sausage at a campfire, get up early the next morning, prepare your glider in the cold sunrise, enjoy the silence all around and once weather is good enough - you take off and come back with the sunset. Then, another beer and sausages, campfire, smalltalk, meeting up with the guys who arrived on saturday - And the same on sunday again. If its raining, you can enjoy it with a good book in your tent, or just do some club stuff. Its the best there is.
You don't need a glider to leave your wife and have a sausage party, it's 2021, gays are openly welcome. Just Google "Twinkies night-club" should be one in your area, Wednesdays are half off drinks.
Back in the 70's I took lessons and my instructor was an elderly lady with a great sense of fun.... we used to buss hikers and dump our water ballast on them...….. lots of laughs from us ! :)
For everyone being mad and saying it should be banned This is an aerobatic manouvre called a finish often performed at the end of gliding races/tasks or aerobatic routines and all the pilots attemting/doing this are more then qualified and most likely have more then several years of gliding experience and have licenses
Fuentemilanos is one of the best aeroclub airfield today for gliding. Apart from amusant, it offers a real wild chances to fly those not-so-far snow mountains during full burning Castilla summer.
You can tell just how fast a glider is going by looking at the shape of the wings. All of them have a certain amount of dihedral, that is sloping upward from where attached to the fuselage and bow upward at the tips in normal soaring flight. At around 100 mph, the wings become perfectly flat, not bowed either way. Above that speed they take a noticeable bend downward at the tips.
All wings, fixed or rotating as in a helicopter or propeller, are made with a twist from the root to the tip, reducing the angle of attack toward the tip. It's called "wash out". Not only is this for better efficiency over a wide range of speeds but it causes separation of the airflow to begin at the fuselage and move toward the tip as the angle of attack increases or airspeed slows. As the nose is lowered to increase the speed, the angle of attack reduces to the point where there is a negative angle of attack at very high speeds creating negative lift at the tips, causing them to actually bend downward. It also involves Reynolds numbers and tip loss but it's the quick and dirty explanation above. Run the video again and you can see the downward flex in the wings toward the tips.
Naturally they will flex upward when one pulls up and applies more G force load on the wings. In flexing upward moves the center of lift toward the fuselage where the wings are stronger.
The stuff that looks like smoke is water ballasts . Anything that flys is dangerous and gravity will teach you that , having said that these guys know what there doing and have a real feel for there gliders .
Yes, all about speed. And about the sailplane you're using. If you try to do that with an old one made of wood and "paper" (i don't know the exact worn in english), you won't regain much altitude than with a morden sailplane.
Saw someone killed doing this in an RV at Black Forest gliderport in the 90's. They did a high speed low pass and pulled up into a wing over and went in. Also a very young pilot at the old Black Forest gliderport also died doing this in a 1-26. The parents named a gliding scholarship after him. Some of you may remember the Kolstad scholarship. My point is that you really better know what you are doing.
I've seen gliders with "popup" rocket engines that can self-launch. No tow plane! But that added weight. They need to invent one that you can eject the rocket after use and have it parachute back to the ground for reuse later. Better yet, build one like the Space-X Heavy that can RTB and land themselves. Strap that to a glider! FUN! (and maybe death. But only maybe.... it might be worth it). ;-)
@@robertzeurunkl8401 you even see it in this video, in some of the videos they are draining water from the wings. They put the water in there to ballast up the plane, because the plane has a higher base speed when it gets heavier, but it also sinks faster. So when good thermal upwinds are expected they will ballast their planes so they can finish their tasks faster, because they can compensate for the higher sink ratio
After executing one of those... usually a tongue lashing by the glider port operator follows. (Bad example for inexperienced students). Always remember... no tow up, no flying.
@@colt.45rc76 Had a H-301 Libelle. Serial #10. May be looking for another ship soon but not in a soaring envirioment right now. (Ca./ Oregon border). Flew Minden Nevada, Truckee, Calistoga.
The future is now, gliders with electric engines are now being produced. This is great for us because the current combustion ones are extremely unreliable, while the electric ones should be very reliable because of how simple they are. Only downside a the moment may be the range they have, but that will improve overtime. I’m gonna be shocked if by 2030 combustion engines on gliders will still be in production.
Very nice. The danger with low flying, is the temptation to go lower and lower till something happens - usually death. Must decide BEFORE to quit at a safe altitude. At very high speeds, glider wingtips bend down due to 'washout'. (Look it up.)
That pass that starts a 5:50 (several actually) are amazing. That thing must be close to 50:1. Makes me wonder how many HP it would take to maintain level 120 MPH flight, not much, I'll bet.

If you pedal hard enough on the rudder that'll keep it up.
@ LOL, when I was a kid I had a pulse rudder RC I built. It basically did just that, just constantly "peddling" the rudder full stop side to side, at maybe 3 Hz or so. When you input a rudder control it would "peddle" a shorter stroke to the opposite side, turning the plane. I never calculated it, but I expect even THAT amount of peddling did pretty much nothing to keep it airborne, probably even caused a goodly amount of induced drag, if I had to guess, and actually hurt the glide ratio. If I'd been thinking at the time, I could have done some glide tests with the rudder pegged center, and with it operating to see. Didn't though. Maybe better that way. ;-)
This is the "EP", a Schempp Hirth Nimbus 4 and ratio is roughly 60:1, top speed 290km/h. The Nimbus 4DM has an engine with roundabout 50HP, to maintain level with about 130 km/h I think. Regards from Germany
That's right. The variometer provides audio too. Therefore you can concentrate on the other vital instruments (mainly speed, altimeter and turn and slip indicator).
Robert B id the adult and child has stopped to look left at incoming aircraftthey could easily have been hit -great footage but massively dangerous in that case . The pilot must’ve checked for cables and fencing etc before flying those loops ?
Now even gliders are laying down Chem trails! I guess with the price of fuel this is a greener alternative when dumping chemicals. And the earth is also flat haha
@@DB-thats-me That sound is the wind Jesus.. Where the f**k do you have your brains??? Jet powered gliders havve jet fuel inside the cockpit... In the wings you have ONLY watter balast... Sorry but you clearly do not know ANYTHING about gliders!!!
Похоже у него тяга есть не от термиков, а от реактивных движков. Шум в кабине не соответствует. Летал я на планере в 70-х. И снаружи звук маленьких реактивчиков. Что-то тут не чисто...
Ничего не понял. Когда мне в 76-м довелось подлетнуть на Бланике, всё было не так. Взлёт, набор, отцеп, построение захода, посадка. А тут непонятные кренделя с очевидной тягой...
