There were the RD-117/118 upgrades which flew 786 times from 1973 to 2017 on the Soyuz U and U2. They were very similar to the original RD-107/108 and had only minor structural changes. For example, they had different injectors, which increased their performance a little.

The RD-107 (Russian: Ракетный Двигатель-107, romanized: Raketnyy Dvigatel-107, lit. 'Rocket Engine 107') and its sibling, the RD-108, are a type of rocket engine used on the R-7 rocket family. RD-107 engines are used in each booster and the RD-108 is used in the central core.

Specific impulse sea level: 264 s. Burn time: 130 s. Chambers: 4. Oxidizer to Fuel Ratio: 2.47. Country: Russia. Launch Vehicles: Soyuz-ST-B. Propellants: Lox/Kerosene. Stages: Soyuz ST-0. Agency: Glushko bureau. Bibliography: 318, 7497.

When activated, the Air Locker prevents the internal differential gears from rotating and therefore prevents the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times.

RD-170系列是人类有史以来威力最强的液态 火箭发动机，是 动力机械科研生产联合体 为了 能源号运载火箭 设计及生产的。 RD-170发动机的研制最早要追溯到1973年。 当时 N1运载火箭 发射的失败后，就打算研制大推力的发动机，提议研制的RD-123发动机，推力要达到800吨，RD-150发动机的推力要达到1 500吨。 事实上RD-123和RD-150发动机达不到要求，RD-123发动机的推力只能达到125吨左右，设计中的RD-150发动机的推力最高只能达到1003吨。 其次还有用于UR …

Created to provide traction on demand, without sacrificing highway driving performance, ARB Air Locker differentials employ a 12 V ARB air compressor (sold separately) to pneumatically operate a solid and durable locking mechanism inside the differential.

rd-107液体火箭发动机是前苏联r-7火箭家族的助推发动机，前苏联发动机代号为ΡД-107。由前苏联气体动力实验室一设计局（现动力机械科研生产联合体）于 1954年～1957年研制。
