Strategic design can protect reliability, cost, weight, and other considerations foundational to mission-critical aerospace systems, according to a new study that compares pressure-reducing systems.
The whitepaper from Marotta Controls, “Analytical Trade Study on Pressure Reducing Systems for Aerospace Applications” compares five pressure regulation designs in four primary system-level configurations and shares parameters for determining which type of pressure regulation system is most suitable for a particular design. These pneumatic solutions are typically found in propulsion systems, launch vehicles, satellites, and ground-support equipment, which are all vital to mission capabilities.
“Even the most experienced system-level engineers may not recognize the broad impact of their pressure regulation design choices," said Keith Brodek, manager of analysis engineering, Marotta Controls, a growing aerospace and defense supplier. "They often stick with solutions that have worked in the past, regardless of whether that technology is right for the new design. This design practice doesn’t always consider the big picture and can introduce unintended performance characteristics and undesired consequences. Our study illustrates the potential pitfalls of oversimplifying pressure regulation selection and highlights the interplay between system components. By making strategic design trades, system integrators can protect reliability, cost, weight, and other considerations foundational to mission-critical systems.”
For this study, the Marotta engineering team developed an algorithm that enables quick-turn analysis, simulating pressure regulation response based on the application’s requirements. To further streamline system-level considerations, the team studied the capabilities of several pneumatic solutions in relation to common system-level application requirements. Results showed that while no single solution fits all system-level designs, early collaboration between system engineers and component manufacturers allows designers to tap into a deeper level of experience that can guide the most beneficial design trade.
