Some of the things that awe me.

Do jet engines have a gear or crankshaft?..

4

It has a shaft for sure, but not a crankshaft. Hakuna pistons hapo.

Most don’t have gears, but there are models that have e.g the troubled Pratt and Whitney 1000G used on A320s

6

Turbo engines not jet engines… Crankshaft are for pistons… Propeller shafts that I can accept or pinions.

Boss a jet engine does not have a gear box and crackshaft, in fact that image you shared of a gear box belongs to mercedes-Benz c-class ( https://3d-car-shows.com/mercedes-benz-c-class-engine-and-drive-system/ )

Also, the jet engine you shared is General Electric Affinity, one of the most impressive jet engines but only for regular aeroplanes (maximum altitude 60k ft) ( https://www.geaviation.com/bga/engines/ge-affinity )

Otherwise, indeed the space shuttle was a marvel, ahead of its time

I don’t see anywhere, or anything stating anything that implies a jet engine has a gear box.

What about the GE jet engine ?

It seemed like on your original post you were associating all those pics with the space shuttle. if not…, I get you

My original post. ’ What a marvel. The space shuttle. The Jet engine. The Gearbox. The Crankshaft. Where is the association?

you made your point brathe, stop pushing limits here

Wankel engine does not have a crankshaft ?

I have to admit I have absolutely zero knowledge concerning cars and jets, leave alone space shuttle. Yet this thread, it seems so to me, is so misleading. First, your thread title insinuates that everything about this post will be about space shuttle, and so I choose to take it as such. Second, the simplest explanation I understand about manual transmission in car engines is that it is there to control the speed of the vehicle. So why would a jet require a manual transmission engine yet its speed is always constant? Another thing, I usually see rockets as pointed objects that point in the sky (as depicted by your first pic ) while being propelled by the force behind it we usually see as “fire,” so where exactly is its engine that looks like you have showed us in this thread? I could be wrong but I deserve to know the truth and have my questions answered, otherwise @sakwa raises a valid point, I dont understand why you are so quick in shutting him down

Whatever
