Simple Blowdown System Performance Estimate

Here we'll briefly walk through a simple performance estimate for a blowdown propulsion system. This is useful for assessing the orbital maneuver capability of a proposed design and determining the end-of-life (EOL) pressure.

Atmospheric Drag on LEO Spacecraft

Spacecraft lifetime in LEO is highly dependent on the atmospheric drag force and it's removal of energy from the satellite's orbit. Understanding the impact of drag on a design is important for early propulsion sizing estimates for spacecraft operating in the very low earth orbit (VLEO) range of 250-450 km.
