In 1957, Jalbert invented the ram-air airfoil and began testing and formalizing the design.<ref>{{cite web |url=http://www.drachen.org/journals/a10/Domina-Jalbert.pdf |title=Archived copy |
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. All parafoils today owe their roots to Domina Jalbert's invention.
Line 21:
Domina Jalbert was first to teach of the robust airfoil formed by the ram-air principle. Every contemporary ram-air airfoil sport and utility wing began with Domina Jalbert's invention.
<!-- this section is about parafoils and parachutes and not about Jalbert -->
When the parafoil is used as a gliding parachute, thus opening after the payload or human has been in free-fall, the opening of the parafoil can be very fast; the fast opening and the consequential related shock has to be damped; devices invented by others are used to slow down the opening of the parafoil. One such invention is the [[Slider (parachuting)|slider]]. When the parafoil is used in hang gliding as a paraglider, the parafoil is kited open before the human leaves the ground; in such cases a slider is not necessary.<ref>{{Cite book|url=https://archive.org/details/goldenknightsusa0000hopk|url-access=registration|quote=Domina Jalbert ram air wing.|title=The Golden Knights: The U.S. Army Parachute Team|last=Hopkins|first=Ellen|last2=Bledsoe|first2=Glen|date=2001|publisher=Capstone
