Kuznetsov NK-32
The Kuznetsov NK-32 is an afterburning three-spool low bypass turbofan jet engine which powers the Tupolev Tu-160 supersonic bomber, and was fitted to the later model Tupolev Tu-144LL supersonic transport. It produces Script error: No such module "convert". of thrust in afterburner.
A non-afterburning variant known as NK-32 Tier 2 for Tu-160 and NK-65 will be used in the upcoming Russian bomber, PAK DA.[1]
NK-65 and a geared high-bypass turbofan variant PD-30, with a thrust of Script error: No such module "convert". has been proposed for use on new Russian wide-body airliners, as well as the upgraded Antonov An-124 Ruslan heavylifter.[2][3]
