To The Moon & Mars - Aerospace Engineering: Crash Course Engineering #34

This week we’re exploring aerospace engineering and its two main fields: aeronautical engineering and astronautical engineering. We’ll explore life & buoyancy, propulsion systems, and the challenges of managing the human body in space.

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’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

[Quasarnova]

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.

0:58 I love the red Tesla car reference

It's one of my favorite main fields aerospace engineering along with electrical engineering and physics, and mechanical engineering

[luxeproultimate]

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

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!

[unleashingpotential-psycho]

Aerospace engineering is truly incredible. 🔥🔥🔥🔥

[engibear]

*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.*

It is fascinating that we can learn this much information for free😁👍👍

[ChocolateMilk]

I want to be an Astronautical engineer so badly!

[descentplayer]

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.

[azertyQ]

"competition drives innovation" disregards the amount of collaboration that is required to compete

[mrman]

everybody should play Kerbal Space Program, you will learn sooo much about this topic

[Hallebumba]

argh. the fan is not the inlet. also it provides most of the thrust in a turbo fan.

[ellaser]

I wonder if she's gonna go into talking about Genetic Engineering at some point.

[kurtweinstein]

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.

[lildracable]

I’m so excited to do mechanical engineering! It’s gonna be one of my majors for University :)

[myronify]

I love watching crash course when I'm stoned. Lol

[camiloiribarren]

And now we have come to the age of space. This is fun and interesting. Let’s build the Millennium Falcon
