What happens if a parachute is too big?

How large a parachute is (in other words, the parachute’s surface area) affects its air resistance, or drag force. The larger the parachute, the greater the drag force. In the case of these parachutes, the drag force is opposite to the force of gravity, so the drag force slows the parachutes down as they fall.

What is a parachute made of?

A parachute is a device used to slow the motion of an object through an atmosphere by creating drag (or in the case of ram-air parachutes, aerodynamic lift). Parachutes are usually made out of light, strong fabric, originally silk, now most commonly nylon.

How fast does a parachute slow you down?

Parachutes are designed to reduce your terminal velocity by about 90 percent so you hit the ground at a relatively low speed of maybe 5–6 meters per second (roughly 20 km/h or 12 mph)—ideally, so you can land on your feet and walk away unharmed.

What happens if you pull the parachute too early?

You are likely to drift off the drop zone. The winds can be pretty heavy at high altitudes, and unless you steer continuously they may blow you off-course. Needless to say, the refrigeration effect of the wind and slipstream will make you feel even colder than the mere altitude. Your landing is likely to be rough.

The length of the string should be equal to the radius of the desired circle. Attaching the suspension lines: Use 4 suspension lines for each parachute. You can tape or tie the suspension lines onto the canopy.
