Tumansky R-29
The Tumansky R-29 is a Soviet turbojet aircraft engine that was developed in the early 1970s.[1] It is generally described as being in the "third generation" of Soviet gas turbine engines which are characterized by high thrust-to-weight ratios and the use of turbine air cooling.[2]

gollark: Approximately, sure. But with higher skilled jobs. And you could still have offices and whatnot if your contract included coming in to physically work with people.
gollark: > cuz if everyone would run a business things wouldnt go well(responding to this)
gollark: Not under the current model of work, but you could replace "go to work and are paid to do whatever is directed by someone" with "hired on contract to perform some specific task".
gollark: Um, very late, but stuff probably could still work fine if everyone was self-employed in some way.
gollark: (I also now want to see if we can convince him we're agents of Russian intelligence)
