Hold up a minute here! You guys spent several episodes on environmental engineering stuff, but just 1 brief overview show on both aeronautical and astronautical engineering? That seems rather unbalanced to me.
I think basic lift and thrust equations could have gone a long way in this video, aerospace engineers are much more concerned with those than making spacesuits, which would be more a job for biomedical engineers.
They spent several episodes on environmental engineering stuff, but just 1 brief overview show on both aeronautical and astronautical engineering. That seems rather unbalanced to me, so I wouldn't get my hopes up.
My friend and I once tried to get a tour at SpaceX Hawthorne facilities because we were in town during a vacation. We talked to an engineer on his way to work there but the security guy did not let us in, in the end. Still those guys working there are legend!
*At this point, I'm looking at previous comments for guidance because my ability to criticize outside my own field are limited.* *Good points:* *1. While it is technically true that spacesuits can be thought of as ships, there's not really much aerospace engineering that goes into them.* *2. Very basic concepts like the rocket equation and its tyranny over engineers were skipped over.*
I'd of figured a mention of the rocket equation would have been given to explain the critical difference of generating thrust in a vacuum, as opposed to the description given of how jets generate thrust.
The thrust equation for rockets is very similar to the thrust equation for jets, but without the mass flowrate in. The rocket equation is different and usually used for calculating a change in velocity.
@@Quasarnova1 My point was that the jet relies on an atmosphere for oxidizer and the principle exhaust generating thrust. The rocket equation illustrates the challenge of space travel by showing rapid diminishing returns as you increase the amount of fuel and oxidizer. The comparison would be even more stark when set against a solar electric propeller aircraft.
@@kurtweinstein8450 Sure, but the rocket equation is not a thrust equation, and you can't really apply the rocket equation to jets since they are more concerned about cruising and drag than reaching a certain speed. Conventional aircraft also have also have diminishing returns with increased fuel, though not as badly as rockets of course. Maybe a comparison of the specific impulse of different engine types would be a good way of showing the difference in efficiency, though even that isn't the whole story.
@@Quasarnova1 I never said it was a thrust equation and I did not mean to say that it should be applied in a direct comparison with aircraft. I think you are missing the point which is to demonstrate key differences between aircraft and spacecraft, the relationship with the external environment in generating thrust (and hence achieve a change in velocity) being a particularly important one. They addressed what makes a jet "go" but not the same thing for a rocket. If they had talked about rocket propulsion then discussing the rocket equation could have been useful for illustrating a fundamental concern of astronautical engineering.
Keep in mind that her script was probably correct, but she’s not the one doing the animations, it’s an actual animation company. So the fact that the person animating that probably didn’t take any classes on aircraft, I am glad that it was mostly correct. Although, I kinda wish they would do just an aerospace engineering mini-series, just because it is such a massive topic, and covers so many different things. Like she didn’t even cover the other kind of lift besides buoyancy, or the airfoil design, or really anything else having to do with planes. It kinda felt like they mostly skipped over the “aero” part of “aerospace” and went straight into spacecraft. Like what about propellers, and control surfaces, and reciprocating engines, and all that other stuff? I was the most shocked by the fact they didn’t explain how lift is generated by an airfoil, that is like the core concept of aircraft.
The set is great. The wavy back of the chair. The asymmetrical geometric design of the shelves. A definite artistic step up from most RUclips videos. The information was clear abs interesting. Thank you.
The turbine does not produce the thrust in a jet engine. It siphons off a portion of the energy from combustion to run the fan and the compressor. The energy of the thrust is produced by the combustion of the liquid fuel. The thrust itself is a demonstration of Newton's 3rd law. For every action, there is an equal and opposite reaction. The combustion speeds up the air, which is directed rearward. The reaction is to push the plane forward.
i go to a technical school, my shop is advanced manufacturing and i want to take aerospace engineering, it’s been my dream for a while now. so thank you for this video
I been wanting to be a engineer for my whole life, my mom is a chemical engineer and my dad is a software engineer so I knew a lot about engineering. In my start of high school, I knew I had to chose something for what job I want in the future. So, I studied some engineering jobs and I live by the Houston NASA place where my family always visit which I thought was so cool. So I think this might be for me. 💫🌙👍🏾❤️
Love crash course but this episode seemed to skip a hell of a lot of aerospace stuff. i'd have had space travel as a seperate episode. it also seemed very USA centric.Who calls imperial measurements english measurements? The UK adopted metric decades ago and the USA still hasnt as far as im aware.
Is aerospace engineering a part of mechanical engineering? What I mean is can I take a bachelor in mechanical engineering, then take a master in aerospace engineering?
The highlights in the Jet Engine graphic could use correction. The inlet is the passage the air moves through; the graphic highlights and points to a fan, which is properly part of the compressor stage.
The fan isn't really part of the compressor stage either, since most of the air that goes through the fan bypasses the turbine completely. It's more like a propeller in front of the turbojet to help it get better efficiency.
hooray, finally we get to "military-industrial complex engineering". We've got great branding for it here in the US though, "defense", as if we're somehow just protecting ourselves LOL
Are rocket engines heat engines? I know that the fuel in rocket engines generates a lot of heat, but the thrust of a rocket engine comes from the expanding exhaust gasses. Things like cold gas thrusters are like simplified rocket engines, and they don't involve much heat.
Centrifugal force to simulate gravity was tested by nasa, a problem was found on a short radius, If I remember properly, the Semicircular canals is too sensible and if you move your head too quickly it will disorient you and can cause motion sickness. The problem should theoretical not happen with a bigger radius, and the speed needed to maintain a earth like gravity would also be lower, meaning a less disorienting view outside the windows, sad part is the material required to build it and the mass would be too much for our current thec
@@ArawnOfAnnwn it can be trimmed with down and done using wires and pod, two space x ship could teater Each other but it will be imposible to adjust the orbit until they stop and unteatet
Mars Venus and mercury then Pluto then we launch from Pluto on our first interstellar mission but my brain can’t comprehend anything at that time or think of anything past it
What are the 5 core elements of a jet engine? I forgot and I can’t find it in the vid without watching the whole thing and I don’t want to watch the whole thing again
What about a nuclear fusion propulsion system one within a specific heart range Propel to aircraft at least is closest to the speed of light as possible think it's feasible considering nuclear fusion is harnessing the power of the Sun
Well, we still not developed materials that can sustain the heat generated by fusion. It also needs a lot of energy to create a magnetic field that contain the reaction. But it is something to dream about.
I'm surprised that an obvious transition from aeronautics to astronautics was missed here: how you can't push air around to fly in space like you can in the atmosphere, and instead have to deal with rockets and orbits. Flying via jet engine and getting into orbit via rocket are fundamentally different things even though they seem similar on the surface, and the difference between them is interesting (and basically defines the difference between space and not-space: if you can fly, you're not in space; if you can orbit, you are).
*The education level of the person speaking. Same as the difference between a "reinforced concrete pier wall" and a "bridge support" as well as between a "worm drive" and a "doohickey."*
I just want to design and build an iron man suit that could allow us to survive a car impact but if it allows for space exploration why am i not going into aerospace engineering? I can only dream right?
I have been a big fan of crash course for a few years now - however, the level of gross inexactitudes this episodes contains regarding fundamental aerospace engineering and turbofan architecture is baffling. Things seems to be getting sloppy and loose at crash course HQ. Corrective action is needed ASAP.
"English" units? No, they were using IMPERIAL units, which are only really used in America. "USCS, the US Customary System, or US Customary Units" are the correct name for them. The UK still measures distances in miles, but are way too sensible to measure Forces in pounds and inches.
I’ve lately been really into aerospace engineering and this video made me even more interested into it now I just want to peruse this career
Orlando 26 Its awesome, im studying it rn and I feel like Tony Stark lol

Just started my aeronautical engineering degree. It's pretty tough but we find comfort in the knowledge that we aren't Mechanical Engineers :)
Proud aerospace engineer ! 😍

"competition drives innovation" disregards the amount of collaboration that is required to compete
argh. the fan is not the inlet. also it provides most of the thrust in a turbo fan.

Actually, In a turbo fan, most of the thrust come from the bypass duct, not the fan itself. The fan just sucks in the surrounding air
@@Tunechi65 and the Fan is the only thing that puts air in the bypass duct, thus it is responsible for that thrust
@@Hallebumba just making sure you aren't confusing bypass to the main core of the engine
@@Tunechi65 nope just happen to be studying aerospace engineering ;D
The set is great. The wavy back of the chair. The asymmetrical geometric design of the shelves. A definite artistic step up from most RUclips videos.
The information was clear abs interesting. Thank you.
I wonder if she's gonna go into talking about Genetic Engineering at some point.
I think it's VERY likely ;)
ThickNavyRain Insider info?
Love these engineering videos! I plan on studying engineering, but I’m still not sure which.
Spoiler alert from 2024. Still no humans heading to Mars.

You are talking about turbofan while she is talking about turbojet where the thrust is produced by the combustion output.
Thrust in turbofan come mostly from the bypass duct. Not the combustion itself
No he’s correct

SpaceX!
It actually takes faith in the Omnissiah and proper appeasement of the machine spirits to get to Luna.
Is aerospace engineering a part of mechanical engineering? What I mean is can I take a bachelor in mechanical engineering, then take a master in aerospace engineering?
I can't say what you need to do in between but the limitations might be in your budget or time 😉
Good video.
Please do crash course architecture. Pretty please
Great video!
You should do crash course mathematics!!!!!
