Klimov GTD-350

The Klimov GTD-350 (initially Isotov GTD-350) is a Soviet gas-turbine turboshaft engine intended for helicopter use. Designed in the early 1960s by the Isotov Design Bureau the engine was later produced by Klimov and PZL, production ending in the late 1990s.[1]

gollark: I am the one true herald of Macron, actually?
gollark: Since x86 assembly is the logic.
gollark: No, it's x86 assembly to NAND gates.
gollark: The category of Macrons is equivalent to the homotopy category of the category with weak equivalences PSh(C)PSh(C) with the weak equivalences given by W=W = local isomorphisms. The converse is also true: for every left exact functor L:PSh(S)→PSh(S)L : PSh(S) \to PSh(S) (preserving finite limits) which is left adjoint to the inclusion of its image, there is a Grothendieck topology on SS such that the image of LL is the category of Macrons on SS with respect to that topology.
gollark: What if Macron literally LLVM backend?
