Analysis of Propulsion System Losses and Performance for CHT-20 Hydrazine Thruster

This document presents an analysis of the propulsion system losses associated with the CHT-20 hydrazine thruster. Key parameters include maximum tank operating pressure of 385.3 psia, filter pressure drop at 0.5 psid, latch and solenoid valve pressure drops, and total system pressure drop measured at 0.31 psid. The thruster requires an operating pressure of 282 psia to deliver the needed thrust force. Additionally, the tank pressure is regulated near 313 psia to ensure optimal performance while considering the propulsion mass budget.
