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.
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.
And due to controllable rear-facing vents in the canopy's sides, they also have much snappier turning capabilities, though they are decidedly low-performance compared to today's ram-air rigs. From about the mid-1960s to the late-1970s, this was the most popular parachute design type for sport parachuting (prior to this period, modified military ...

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.
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 1994. Germain made a full recovery and went on to personally test many of the airlock prototype parachutes, often in extreme conditions.
The increased pressure in the air box will ultimately have a positive effect on engine output as more oxygen will enter the cylinder during each engine cycle. Ram-air systems are used on high-performance vehicles, most often on motorcycles and performance cars. The 1990 Kawasaki Ninja ZX-11 C1 model used a ram-air intake, the very first on any ...
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
