What size parachute do I need for a model rocket?
Rockets 12″ to 18″ tall – use a 12″ chute. Rockets 18″ to 24″ tall – use a 12″ or 18″ chute. Rockets 24″ and taller – use a 18″ or 24″ chute.
What is a parachute in a model rocket?
The streamers/parachutes get deployed by the rocket engine. The engine has a stage that moves the rocket up, and when that stage is used up, a second stage ignites that blasts a small charge back up the rocket tube, in the direction of the nose-cone. This pushes the stuff in the rocket out.

about 20%
Spill holes keep the pressure from getting so high that the parachute has to rock from side to side to release it. The spill hole needs to be about 20% the diameter of the parachute.
How do I know what size parachute I need?
The drag area of the parachute is calculated as Pi * D / 4, where D is the reference diameter. For flat sheet chutes like Top Flight, the reference diameter is the flattened diameter of the chute – again the diameter quoted by the manufacturer.
How do parachutes eject?
In most designs, the seat is propelled out of the aircraft by an explosive charge or rocket motor, carrying the pilot with it. Once clear of the aircraft, the ejection seat deploys a parachute. Ejection seats are common on certain types of military aircraft.
Does SpaceX reuse Dragon parachutes?

The booster had a soft splashdown in water just off the coast of Cape Canaveral, but SpaceX never reused it. Parachutes also introduce higher turnaround times and points of failure. Parachutes are easily damaged and must be repacked by hand. The heavy parachute deployment system must work perfectly each time.
Should a parachute have a hole?
Parachutes catch a lot of air, creating a lot of drag. They can drastically slow a fall, allowing a softer landing. Some parachutes have a hole in the center to release air in a controlled way. It makes the chute more stable, with only a minimal change in drag.
What are parachutes used for in rocketry?
Parachutes. Drogue Parachutes – Used for high altitude rockets as part of a dual-deployment set-up. These parachutes are constructed so they are stronger and more durable than other parachutes of the same size. Competition Parachutes – These are the lightest weight parachutes because the mission of the rocket is…
How tall does a rocket have to be to use a chute?
Simple rules of thumb for standard sport rockets: Rockets 12″ and shorter – use streamer recovery or an 8″ chute. Rockets 12″ to 18″ tall – use a 12″ chute. Rockets 18″ to 24″ tall – use a 12″ or 18″ chute. Rockets 24″ and taller – use a 18″ or 24″ chute. I recommend using snap swivels on all rockets.
