How do the upgrades involving subcooled components enhance New Glenn's performance profile?
Answer
They allow for denser fuel loading, resulting in a higher delta-v budget
Blue Origin has implemented enhancements, including the use of subcooled components, to boost performance beyond initial design parameters. Subcooling involves cooling propellants to temperatures below their normal boiling points, which increases their density. Carrying a greater mass of propellant within the existing tank volume directly translates into an increase in the vehicle's total delta-v budget. This increased energy capability can then be strategically utilized by the operator to either carry heavier payloads or inject those payloads into higher-energy orbits.
