Quick Overview
The Micro-Newton Variable Thrust Module integrates a proportional thruster and a mass flow sensor. The proportional thruster adjusts thrust according to control commands by regulating the throat area of the proportional valve, achieving precise and continuous thrust control. The mass flow sensor measures the real-time gas flow rate to ensure feedback accuracy and closed-loop control. This module provides high-precision, ultra-low-thrust output, making it suitable for formation-flying satellites, drag-free control, and space science missions requiring ultra-stable micro-thrust environments.
