The NK-33 was an improved version of the earlier NK-15 engine, which powered the original N1 launch vehicle. Key upgrades included simplified pneumatic and hydraulic systems, advanced controls, enhanced turbopumps, an improved combustion chamber, fewer interfaces employing pyrotechnic devices, and modified interfaces to facilitate replacement ...

nk-33和nk-43是苏联60年末70年代初由库兹涅佐夫设计局设计制造的火箭发动机。 用于登月火箭 N1 。 NK-33的 推重比 是当前比冲最高的火箭发动机之一。

nk-33是从n1火箭项目的nk-15煤油发动机发展而来的，推力约1500 kn左右，采用了富氧燃烧和分级补燃技术，推重比133.7：1。 [1] NK-33发动机的设计实现了较高的性能和很轻的结构重量。

A legendary NK-33 (14D15) rocket engine was originally developed to carry Soviet cosmonauts on their way to the Moon onboard a giant N1 rocket. After the ill-fated lunar effort was aborted in 1974 , dozens of already manufactured NK-33s ended up in storage.

nk-33和nk-43是蘇聯60年末70年代初由庫茲涅佐夫設計局設計製造的火箭發動機。 用於登月火箭 N1 。 NK-33的 推重比 是當前比沖最高的火箭發動機之一。

NK—33发动机的结构牢固可靠,可实现很高的泵出口压力和14.480MPa 绝压的高燃烧室压力,因此,其面积比可达27:1,可产生2913.57m/s 的海平面比冲和3274.1m/s 的真空比冲。

NK-33和NK-43是苏联60年末70年代初由库兹涅佐夫设计局设计制造的火箭发动机，用于登月火箭N1。NK-33的推重比曾经是发动机领域最高的，现已被Merlin1D大幅超越，2014年版本的Merlin1D官方介绍已达到155推重比，同时其比冲也达到了很高的数值。

After initial failures of N1 modified engines with multiple ignition capability and increased life were developed. NK-33 was tested at thrust of up to 204 t, variations of components ratio up to 20% and total burning time up to 1200 sec. Mothballed, never flown until selected by Kistler for their commercial launch vehicle in 1996.

The NK-33 and NK-43 rocket engines are the highest performing Liquid Oxygen/ Kerosene ever produced. They are upgraded versions of the the NK-15 and NK-15B engines which flew on the first four flights of the N-1 Soviet Moon Rocket.

2016年6月3日 · nk-33和-43分别源自早期和nk-15和nk-15v发动机。 该发动机是分级燃烧循环双元液体推进剂火箭发动机，采用富氧预燃室技术驱动涡轮泵。 由于富氧排气可能烧穿燃烧室臂，因而这种类型的发动机是比较少见的。
