Aerospike Engines Explained in 60 Seconds

Aerospike engines explained. Aerospike rocket engines solve one fundamental problem that traditional rocket engines using a bell nozzle have, and that's great, but how do aerospike engines work? I will explain the fundamental principle behind aerospikes and dive deep into their combustion cycle. Additionally, I will talk about the aerospike's problems that traditional rocket engines don't have!

The only problem with this is the exhaust from the turbine itself does not produce extra thrust. It acts as a virtual wall. Aerospike engines theoretically have to come to an infinite point to reach peak efficiency. Instead of building that out with metal, you can get a similar effect using a lower temperature gas.

i would love this explanation video extended

Amazing explanations! Instead of the typical "all around the main points geeks" who barely touch the important parts, you go through them. Thank you.

Great explanation in a simple understandable way. Definitely sharing this, also subscribed.

An engine never gets less efficient as the ambient pressure drops. The ISP in vacuum is always higher than the ISP at sea level. It's just a matter of how much more efficient it gets

I came up with an aerospike motor, to attach to my pulse Detonation rocket, that sounds like a machine gun... and I think it's well suited to that kinda design because there is just a big combustion chamber leading to the nozzle, not all these pipes full of premixed propellants...

Hold on, I thought a rocke engine, ANY rocket engine gets more efficient the higher they go and the thinner the atmosphere gets. I also thought that the aerospike was a solution to under-expansion of high expansion ratio rocket engines, as the ambient air pressure could flow back into the sides of the nozzle and separating the exhaust from the walls of the nozzle, which could cause dangerous shockwave, and the aerospike was designed for this under-expansion by having the ambient air force the exhaust to get pushed towards the wall, which makes under-expansion impossible. Eh, but what do I know?

Very nice clarifying illustration and explanation. Thank you!

I was just about to ask, but at the end I got my answer. Cooling looks like it would be very difficult to accomplish

Excellent video, subscribed (with notifications) before it was over! 😁👍

[ultra]

Definitely keep this up. This is really high quality content!

[spaceflightquack]

Ein Video indem klassische Engines erklärt werden, wäre super 🎉

[space]

omg ich wünschte ich hätte das Video früher gesehen
das hätte ich echt gut in meiner Hausaufgabe gebrauchen können

Additive manufacturing (the more accurate way of saying 3D printing) is making it easier to engineer these because you could form complex shapes with little manufacturing difficulty.

I remember watching a gundam cartoon where a space craft was so fast, some exhaust came out almost perpendicularly. And I thought that was cool. But that's the exact opposite of what you want. ☺️☺️

[tsume_akuma]

Kind of don't like you calling the Bell Nozzle "conventional" because even within the bell nozzle design, there are a lot of differences between subtypes such as Laval or Stanton. Expansion Deflection Nozzles also look nearly identical to the "conventional" nozzle despite being a reverse aerospike.

[shadowsensei]

Imagine a v3 raptor with an aerospike.

[BlackGhostAngle]

im not genius or something but to me for solution is changing nozzle skirt to hollow tube, this only my childhood daydreams idea as see the problem rocket wasting thrust when about reaching atmosphere

[blondegirlsezthis]

Wonder if the aerospike design used with pulse detonation engines would make them more feasible

Notice those little nozzles are the exact same shape as the regular thruster.
