Aero-Stable
The Straight Arrow. Stability is about Passive Recovery. If the Center of Pressure is too far forward, the rocket becomes an "unguided missile" that wants to tumble.
- 📐 Static Margin: The distance between CG and CP.
- 🦈 Fins: Used to move the CP further back.
- 🌪️ Damping: How fast the wobbling stops after a gust.
Stability Oat
Self-Correcting Geometry. Aerodynamic stability ensures that the atmosphere works with you, not against you, by using the wind to maintain your vector.
- 🏹 Arrow Effect: Keeping the drag behind the weight.
- 📈 Alpha Angle: The angle between where you point and where you move.
- 🛡️ Passive Safety: No computers needed for a stable shape.
Vector CG
The Anchor Point. Center of Gravity is the Structural Soul of the vehicle. It dictates how the rocket responds to steering and where it naturally wants to pivot.
- ⚖️ Equilibrium: The point where all forces sum to zero.
- 🔄 Rotation: The center of every tumble and turn.
- ⛽ Dynamic: CG shifts as the mass "diet" continues.
Vector CP
The Force Resultant. Center of Pressure is the Balance of the Wind. It is the invisible hand that tries to flip your rocket if it isn't properly placed behind the CG.
- 🦈 Fins: The primary tool used to "pull" the CP toward the tail.
- 📈 Aerodynamics: Purely a function of shape and air flow.
- 🏁 Trailing: CP must always follow the CG for stability.
Balance Fail
The Pivot War. When CP and CG aren't aligned within the "Stability Margin," the aerodynamic forces overwhelm the mass. You lose the Vector of Intent.
- 🔄 Tumbling: Caused by "Nose-Heavy" pressure.
- 🌬️ Veering: Caused by "Tail-Heavy" pressure.
- 🚨 Critical: The rocket follows the wind, not the pilot.
