Flight Demonstration of a Micropump-based Stage Pressurization System

Vector Launch, Inc. proposes to applyrecent advances in micropump and additive manufacturing technologies to develop and demonstrateamicropump-based autogenous pressurization systemfor its commercial Vector-R and mature the technology with multiple static-fire-tests leading to a demonstration flight test (TRL 6). The Vector-R is a 2-stage pressure-fed, LOX/subcooled propylene commercial small launch vehicle, designed to place up to 60 kg in low earth orbit. Electrically-driven micropumps drive a small portion of each propellantover anovel 3D-printedheat exchangeratthe engine to pressurize the tanks.Excess flow can be diverted to the engine as needed.This approach reduces system mass, complexity and acquisition cost as well as operational costs. It eliminates the need for all high-pressure tanks and associated components. It can be used on any pressure-fed stage, for launch vehicle and in-space application when using high vapor pressure propellants such as LOX/methane or LOX/propane. As such, it is an enabler for missions targeted to use in-situ propellants since the need for a separatepressurantlike helium is either greatly reduced or eliminated.By leveragingVector’songoingcommercially-fundedVector-R micro-launcherdevelopment, it is possible toreachTRL6-ready systemduring Phase IIandtransition to the Vector-R operations (TRL-9)soon after.
