RAPS evolved into the category system, which allows students to use ram-air canopies from their first jump. In the early jumps the parachute is deployed automatically using a static line; after proving basic proficiency the student progresses onto freefall, opening their own parachute by means of a ripcord and spring-loaded pilot chute. The ...
The RA-1 Military Free-Fall Advanced Ram-Air Parachute System (MFF ARAPS) provides a multi-mission, high-altitude parachute delivery system that allows personnel to exit at altitudes between 3,500 feet and 35,000 feet. The parachute, which replaces the current MC-4 parachute, supports a total jumper weight of 450 pounds.
Overly rapid deployment was an early problem with ram-air designs. The primary innovation that slows the deployment of a ram-air canopy is the slider; a small rectangular piece of fabric with a grommet near each corner. Four collections of lines go through the grommets to the risers (risers are strips of webbing joining the harness and the ...
A parachute airlock, often abbreviated to airlock, is a safety mechanism built into some parachute models which helps them resist losing their shape while open. It uses a ram air structure to stiffen each section of the outer edge. The design was first developed by parachute inventor Brian Germain following a near-fatal ram-air wing collapse in ...

If you've ever been skydiving, this is something you never want to happen -- losing your parachute while you're plunging to Earth. Terrifying video shows man's quick move after losing parachute ...
Ram air refers to the principle of using the airflow created by a moving object to increase ambient pressure, known as ram pressure. Often, the purpose of a ram air system is to increase an engine's power. The term "ram air" may also refer to: Parafoils, also called ram air parachutes, non-rigid airfoils inflated by wind
A slider is a small rectangular piece of fabric with a grommet near each corner used to control the deployment of a "ram-air" parachute. Also called a "reefing device." [2] A ram-air parachute has a tendency to open very rapidly. At high velocities, the opening shock from a rapid deployment can cause damage to the canopy or injury to the jumper.
