Aerobraking Δv

First-order drag-only Δv≈½ (Cd A/m) ρ v L with state held constant along the path.

Formula

Δv ≈ ½ β⁻¹ ρ v L

Aerobraking pass Δv

Primary sources

• Drag coefficient (NASA Glenn Research Center): Drag force ½ Cd ρ A v². The aerobraking page is the first-order constant-state speed loss from that force.
• Aerobraking design report (NASA): Aerobraking is a corridor and an integrated pass. This calculator is only the constant-state drag decrement.
