AILERON MOLD FOR AEROBATIC AIRPLANE
How many layers, and what weight are the ribs constructed of? And how much weight do you save going carbon wing?
Nice,,,,
Awfully quiet
It is really a very stiff wing, and problaby very strong. Normally the maximum lift occurs at 12 to 15 degrees angle of attack. Testing a wing had to be done under that angle because the sine of 15 degrees (0.2) works as a forward bending moment in the plane of the wing. Otherwise said, the rear spar is tension loaded by this component. Testing it at zero degrees is wrong, because you have no lift in that condition. A 1th year aviation student knows that.
I especially enjoyed the excellent narration 😉
How much do the wings weigh?
Beautiful
Can you explain in detail the setup for the load test? Thank you very much!
What is that white glue you add there for the beam to attach the other skin ?
Claudio, vc não consegue fazer um vídeo falando sobre construção de peças em materiais compósitos?? existe uma certa deficiência desse conteúdo no YT, principalmente em português, só tem coisa básica, peças que não são muito exigidas, seria interessante alguns vídeos falado coisas como quais os tipos de fibra núcleo, colas, resinas, além de coisas como porque da fibra estar naquela orientação especifica, além de outras detalhes que eu nem imagino que existem kkkk
Infelizmente quem domina esses conhecimentos geralmente não compartilha
What is that brown material applied before carbon fiber?
Qual material você usou?
Olá, desculpe a demora em responder, usamos PVC
massa! é tooling board ou algum outro material?
@@pedrobalduci7754 exatamente, usamos um programa executa uma maneira de colagem parecida com uma pirâmide asteca, racionaliza material
@@claudio767 nao sabia que exoistia um programa que fazia isso sozinho! e nunca encontrei tooling board aqui no brasil
After working at Gulfstream for over 18yrs and with carbon fiber lay ups....... I can tell you that we never did a lay up without white, lint free gloves on because of the oils in your skin
That's the difference between manufacturing a certified aircraft and an experimental - relaxation of process. I would use gloves whatever composite system I am using. Proper air extraction and a clean room environment are also key H&S aspects, even if the work is Experimental.
Hi Claudio, thanks for sharing. What material was the CNC carving in there?
Hello, sorry about my delay to answer you, material that we used is PVC, POLYVINYL CHLORIDE, it’s good to handle and don’t suffer problem with humidity and temperature
What ,resin epoxi or poliester
Is that green material some kind of foam or honeycomb?
Yes, it’s foam
so that's why they're so incredibly expensive! beautiful.
terus berkarya, mohon di sertai penjelasan.
How thick are the wing skins?
Nothing compares to the feeling of popping a fresh layup out of the mold and seeing the results of all that work.
what? no heating, no pressing?
No autoclave that big!
@@danielmiller2886 aircraft industrie has autoclaves that big and bigger. they put whole wing-parts in it. is heating just optional and just faster?
@@generalrodcocker1018 These guys do not appear to be using prepreg which is fabric that comes with the epoxy already impregnated in the fabric and requires heat to cure. Other, two part epoxies do not require heat, because you mix the curing agent (hardener) in with the epoxy before putting it on they fabric like they did. This looks like a small shop building a prototype and they likely don’t have the hundreds of thousands of dollars required for a giant autoclave. I worked in a very small shop doing this very thing once, and we never used prepreg.
@@danielmiller2886 this is very, very interesting! thaks for explanation
i don't know one single general aviation company that actually uses autoclaves to manufacture their products. they normally use ovens (aka post curing rooms) and vacuum systems
Is this composite wing made with room temperature cure prepreg? I see the vacuum bag. But no autoclave. You don't get much flow using RTC.
Hello! We doesn’t use prepeg , just vacuum process of 12 hours and than 12 hours on a RTC ROOM
@@claudio767 What is the sheet goods being laid down at 0:26? It looks a lot like prepreg. If not prepreg, when do you apply the resin?
I think the word "Aerobatic" is meant to be "Aerodynamic".
please make long duration video of this...i need to learning about arms controlling
Wow amazing work . But if you can make a video with voice part details
Achei estranho uma coisa, em planadores de competição, as metades das asas (superiora e inferiora) são unidas DENTRO de um molde, sob pressão e normalmente, com sistema de vaccumforming. Nesse video, metade do revestimento foi colada sem uso de molde. Isso faz muita diferença?
Thanks for the video. Its useful.
Hola amigo, ¿todos los materiales son de fibra de carbono?
🙏👍
Please show me how they positioning spar and web
Thanks for sharing knowledge
Beautiful work
Thank you for sharing knowledge sir
Thank you for sharing knowledge sir
Onde fica localizada essa fabrica? brasil?
How much does that wing weigh?
A caixa de Ype me deu confiança para comentar em português: Achei muito legal o video, gostaria que postasse uma narrativa. Deixe indicado de onde vocês são, qual empresa, etc, tenho certeza que será util para aqueles que procuram coisas tão específicas no UA-cam. Bom trabalho!

Nice build, nevertheless bonded structures for use in primary structures category-A are challenging to ensure high quality and safety standards
Can you explain more?
i dont know a single composite GA aircraft that its not glued. in fact, even non-FA are glued too. i cant imagine making a wing with a mouldless AFP or winding.
@@pedrobalduci7754 i should specify, secondary bonding or co-bonding is a challenge, it means a cured part bonded to a non-cured. The quality and therefore reliability of cohesion is more difficult to achieve then for co-cured structures, where parts are cured together wet on wet, or in a one shot infusion process as for dry fiber textiles. For example large commercial aircraft where parts are made of composite, are riveted for the exact same reason. I should say that for a small aerobatic aircraft, the build process is sufficient, if properly executed.
@@servanttofriend8481 It is the challenge of co-bonded structures, means one part cured to a non-cured part. A good bond quality is more difficult to achieve.
Dear sir, it's wonderful job. I have experience also in composite and uav manufacturing. I want to ask can't u give me a job in your company. It's very important for me. I have 12years experience in air frame but military. In addition to I am from Sri Lanka. Can u pls help me sir. I would like to serve your company as well as I can. Thank you.
Very good, thank for video.
What material were the spars and ribs? Look to be aluminum but couldn't tell.
what kind of glue for joining between carbon fiber base layer with frame?
Hysol epoxy
Wonder why you didn't get a copyright strike
excuse me. my name wawan saputra from indonesia. i have question. did this ribs and spar make from composite? thnkyou
Some friggin explanation of what the hell they're doing and some details. I didn't learn not one single thing from this video. Was it supposed to be instructional, or just showing off. You might know how to make an airplane wing, but you can't make a video worth a damn!
Make your own videos then... oh wait, I'm damn sure you can't!
Em que avião é usada essa asa?
SU-26 SUKHOY
some steps not clear, I am wondering how the upper and lower surface are joint together and without any wreck looking at all? I didn't see any steps working on that, can anybody help to explain? Thanks.
how thick are the panels?
that's so cool!!
