Russian Engines

The NK-33 and NK-43 are rocket engines designed and built in the late 1960s and early 1970s by the Kuznetsov Design Bureau. The NK designation is derived from the initials of chief designer Nikolay Kuznetsov. They were intended for the ill-fated Soviet N-1 rocket moon shot.

 

The N1 was a heavy lift rocket intended to deliver payloads beyond low Earth orbit, acting as the Soviet counterpart to the NASA Saturn V rocket. This heavy lift booster had the capability of lifting very heavy loads into orbit, designed with manned extra-orbital travel in mind. Development work started on the N1 in 1959. Its first stage is the most powerful rocket stage ever built.

This heavy lift booster had the capability of lifting very heavy loads into orbit, designed with manned extra-orbital travel in mind. Development work started on the N1 in 1959. Its first stage is the most powerful rocket stage ever built.

The NK-33 engine is among the highest thrust-to-weight ratio of any Earth-launchable rocket engine, second only to the SpaceX Merlin 1D engine, while achieving a very high specific impulse.

The Orbital Sciences Antares light-to-medium-lift launcher has two modified NK-33 in its first stage, a solid Castor 30-based second stage and an optional solid or hypergolic third stage. The NK-33s are imported from Russia to the United States and modified into Aerojet AJ26s, which involves removing some electrical harnessing, adding U.S. electronics, qualifying it for U.S. propellants, and modifying the steering system.

Informacija, kad lapkričio 29-osios naktį sprogusi raketa-nešėja „Antares“ buvo valdoma Ukrainoje surinktu varikliu NK-33, neatitinka tikrovės praneša „Interfaks-Ukraina“. „Ukrainos raketų pramonės gamintojai nedalyvavo, nei šios raketos kūrime, nei jos modernizavime. Raketą kūrė rusų N. D. Kuznecovo vardo Samaros mokslo-techninis kompleksas dar 70-ais metais supersunkiai raketai N-1. JAV iš Rusijos 90-ųjų viduryje įsigijo apie 30 NK-33 variklių, ir šie tiesiogiai buvo pristatyti užsakovui,“ – teigiama pranešime.
