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 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 ...
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.
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
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.
In 1957, Jalbert invented the ram-air airfoil and began testing and formalizing the design. [ 5 ] In January 1963 he formally confirmed his discovery and invention of the ram-air double-surfaced fully flexible airfoil that would profoundly change kiting, parachuting, skydiving, hang gliding, paragliding, sport flying, power kiting, and more.

A Russian Rogallo-Wing canopy known as a PZ-81 was available as late as 1995. The Rogallo wing canopy was superseded in the late 1970s by the ram-air canopies which had improved their reliability and performance, and reduced their packed volume, compared to all other gliding and non-gliding parachutes.
