    NASA invented a space ship powered by a rotary engine? Noice, at least until the apex seals give out, but they should be good for 80k at least.

        The wankel and rdre aren’t really related, but they’re similar in that they’re both oddball engines with surprising performance.

        Of all of my near future rocket engine predictions, a working aerospike rdre was not on my list… I’m honestly very impressed!
