Conical Parachute

The first ever parachute was sketched and invented Leonardo Da Vinci. It was called the conical parachute, fitted in a pyramid shape dome.

In 1797, Andrew Garnerin made the first jump with a parachute without a rigid frame. One of Garnerin's balloon jumps from 8000 feet, a very high altitude for the time, was observed by a French astronomer, Lalandes. As the parachute descended, severe oscillations were induced in the canopy.

How parachutes work!

Parachutes are actually three chutes in one, packed into a single backpack called thecontainer. There's a main parachute, a reserve parachute (in case the main one fails), and a tiny little chute at the bottom of the container, called the pilot chute, that helps the main chute to open. Once you're clear of the plane, you trigger the pilot chute (either by pulling on a ripcord or simply by throwing the pilot chute into the air). It rapidly opens up behind you, creating enough force to tug the main chute from the container. The main chute has to be carefully packed so the ropes that connect it to your harness (known as suspension lines) open correctly and straighten out behind you. The main chute is designed to open in a delayed way so your body isn't braked and jerked too suddenly and sharply. That's safer and more comfortable for you and it also reduces the risk of the parachute ripping or tearing.

Terminal Velocity

The terminal velocity of this skydiver is about 124 mph (200 kph)- 55.6 m/s

The terminal velocity of a falling body occurs during free fall when a falling body experiences zero acceleration. This is because of the retarding force known as air resistance. Air resistance exists because air molecules collide into a falling body creating an upward force opposite gravity. This upward force will eventually balance the falling body's weight. It will continue to fall at constant velocity known as the terminal velocity.
