2. Ram Air Progression System - Wikipedia

   en.wikipedia.org/wiki/Ram_Air_Progression_System

   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 ...

3. Airlock (parachute) - Wikipedia

   en.wikipedia.org/wiki/Airlock_(parachute)

   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 ...

4. Slider (parachuting) - Wikipedia

   en.wikipedia.org/wiki/Slider_(parachuting)

   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.

5. Military Free Fall Parachute System - Wikipedia

   en.wikipedia.org/wiki/Military_Free_Fall...

   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.

6. Parachute - Wikipedia

   en.wikipedia.org/wiki/Parachute

   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 ...

7. Military Freefall Parachutist Badge - Wikipedia

   en.wikipedia.org/wiki/Military_Freefall...

   The parachute is a seven-celled MT1-X, the first ram-air parachute to be adopted by the U.S. Military as the standard freefall canopy. The wings represent flight and airborne capabilities. Free-fall training

8. Paragliding - Wikipedia

   en.wikipedia.org/wiki/Paragliding

   The paraglider wing or canopy is usually what is known in engineering as a ram-air airfoil. Such wings comprise two layers of fabric that are connected to internal supporting material in such a way as to form a row of cells. By leaving most of the cells open only at the leading edge, incoming air keeps the wing inflated, thus maintaining its shape.

9. Powered parachute - Wikipedia

   en.wikipedia.org/wiki/Powered_parachute

   A powered parachute, often abbreviated PPC, and also called a motorized parachute or paraplane, is a type of aircraft that consists of a parafoil with a motor and wheels. The FAA defines a powered parachute as a powered aircraft comprised of a flexible or semi-rigid wing connected to a fuselage so that the wing is not in position for flight ...
