In a dual deployment system, what is the effect of deploying a small parachute at apogee?

• A. Reduces peak loads during descent and improves landing accuracy by deploying a small parachute at apogee and the main parachute later
• B. Increases peak loads during descent
• C. Eliminates the need for a main parachute
• D. Delays recovery entirely

Answer: (A)

Deploying a small parachute at apogee sets up a two-stage fall that makes the recovery smoother and more controlled. The small parachute, acting as a drogue, begins to slow and stabilize the vehicle as soon as the rocket turns from ascent to descent. This early deceleration lowers the speed the main parachute will experience when it finally deploys, so the main canopy inflates at a lower speed and altitude. That gentler, staged deployment reduces the peak aerodynamic and structural loads during canopy inflation and helps keep the rocket from pitching or yawing — which translates into more predictable, accurate landings. The main parachute is still needed for the final descent; deploying a small parachute at apogee does not eliminate it.
