RD-0237

RD-0237 is a designation for a liquid-propellant rocket engine vernier thruster developed by KBKhA (Chemical Automatics Design Bureau) in Voronezh, Russia. Vernier thrusters are small engines used for fine adjustments to a spacecraft's trajectory or attitude.

RD-0237 engines are used as steering engines, providing precise control during different phases of flight. They are typically used in conjunction with larger, main engines to achieve accurate orbital insertion, course correction, and spacecraft orientation. Information regarding the specific spacecraft and launch vehicles the RD-0237 is used on is limited in publicly available documentation but it is known to be part of larger propulsion systems developed by KBKhA.

Key characteristics of vernier engines like the RD-0237 generally include high reliability, quick response times, and precise thrust control. These attributes are critical for the delicate maneuvers required in spaceflight.
