[ARTICLE] Cascade Tank Pressurization Method for Satellite-Delivering Rockets (Canadian Applied Physics Journal / 2025)

Satellite-delivering rockets share a common problem --- the dependency of pneumatic systems on electric networks driven by onboard computers that can fail and cripple/render the rocket inert. One such example is the propellant tank's pressurization system. This article presents a novel approach entitled the Cascade Tank Pressurization Method, that solves this problem by iteratively discharging in a domino effect a cluster of composite overwrapped pressure vessels triggered in series. A Piping &amp; Instrumentation Diagram is available. One-dimensional pneumatic analysis conducted on various size clusters show a fine control --- of ullage pressure to a predefined target bandwidth --- without any computer controls. Ultimately, a disruptive fully-pneumatic self-regulated tank pressurization system is presented, enabling the option for a more computer-decoupled rocket architecture.<br><br>The article was recently published in the open-source Canadian Applied Physics Research: https://doi.org/10.5539/apr.v17n2p40-------------------------------------------------------------------------For more public data, please visit my Figshare profile: https://figshare.com/authors/Luis_Teia/10811244
