The Insane Engineering of the 787

The 60 minute Nebula version is here: nebula.app/videos/real-engineering-the-insane-engi… Part two will launch on YouTube in the next week.

Watching your first videos on aircraft literally altered my career plans, I'm now 7 months away from graduating an aerospace engineer. You are having a big impact on many future engineers. Please keep doing more aircraft videos, they are absolutely amazing!

Lmfao the McGregor shade was completely unexpected but absolutely perfect

As a former Boeing 787 Dreamliner structures and maintenance instructor, this video was a pleasure to watch and had great accuracy!

I think this guy put more effort into this video than Boeing have done with their new fleet of planes

Literally like every aerospace engineer at my college watches this channel religiously. Nothing is gonna get done today except watching this video lol.

Real Engineering blink twice if Wendover productions is holding you at gunpoint.

As a materials science engineer I have to applaud you for the accuracy of these videos. Inelastic vs elastic deformation, galvanic corrosion, S-N curves etc. I was not expecting such specific information to be explained in such an accessible and easily digestible format. This is my first video I’ve ever watched from your channel but you have a subscriber for life. Thank you for all of the work you put into these videos

I have no intentions to study engineering but I absolutely love to learn new things. Thank you for these!

the fact that human beings figured this shit out never ceases to amaze me

"Boeing argues... these expensive features were not needed." Like redundant sensors, properly written software, and pilot training?

Took my first 787 flight from Philly to Dublin and it was phenomenal. Once you’ve flown on one, all later flight suck. I arrived feeling better than I have on flights half the length. And fast. With the strong tail wind it was over so quick.

The production value is stunning. You need Netflix deal or something.

Very nice video, super informative as always. One small note, aerospace composites are cured in an autoclave not an oven. This is important, because it makes scalability even more challenging. 1Bar isn't much, until it's over a surface area the size of a fuselage.

I wouldn’t be lying that you’re making all of us interested in engineering majors plus the quality of the videos is just outstanding and the content is so easy to understand. You’re truly changing the perspective of looking at things for an ordinary person for instance the next time i travel in a Dreamliner, I’ll know that this plane is nothing like a plane 50 years ago. Meaning being able to appreciate the advancements which have lead aviation to this point. Can’t wait for a video on Anti-gravity engines lol whenever your able to get your hands on one! Haha

These videos were not available back when I was graduating. Insane quality and very well explained without using math. Keep this thing going pal! By a fellow aeronautical engineer. Greetings from Italy!

At 18:14, The HLFC panels are actually part of the Empennage Door Actuation System (EDAS). The doors are closed when on the ground. At low airspeed the doors open for "purge mode" sucking air in and sending it up the vertical stabilizer back out through perforations on the leading edge of the vertical stabilizer. During cruise and high airspeed, the doors go into "suction mode" by creating a low pressure at the doors, reversing the airflow pulling air through the small perforations and sending it out the EDAS port. This decreases the thickness of the boundary layer airflow to maintain laminar flow and hence decrease drag along the vertical stabilizer. It is mainly used in "suction mode" as this reduces drag more. The "purge mode" is used more often to remove water and debris from the perforated holes. The EDAS system is only on the vertical stabilizer and is only applicable on all 787-10s and the 787-9s after production line number 526. Other than this part here this is an amazing, well thought through video. Very informative and enjoyable to watch!

On the nose, rivets can contribute to a lot of parasitic drag, but further back they're in the boundary layer and barely make a difference. You'll notice that on Russian fighters, they only bother with flush rivets on the front of the airplane.

I'm irish and a bit of an engineering and aviation geek myself and I have no idea how I have never came across your channel until now! Love the narration and the references to various random things! Great videos and you've got a new subscriber 🙂
