A Review of Aerospike Nozzles: Current Trends in Aerospace Applications

I have some hope that rotating detonation engines will make aerospikes viable. But I don’t even see them mentioned in this paper.

The idea with the constantly moving flame front is that it spreads the heat out. The limitation with aerospikes is getting enough coolant through the spike. Bells are simpler to cool, which as I understand more than makes up for them needing more cooling.

The abstract brings up SSTOs, but has there been anything in recent invention that will make them anything other than the white whale people have been chasing since forever?

I'm not sure if this one counts but recent https://www.youtube.com/watch?v=UShD03eG9IU

Is that an AI generated image of the Venture Star? It's missing portside wings..

I thought this would be about the key-value store, Aerospike.

Pretty neat, my dad worked on that X-33 program at Lockheed.
