Helical Engine

Salut, bonjour,

En surfant sur youtube, je suis tombé sur des vidéos montrant un nouveau type encore théorique de propulsion (il date de 2019):

Helical Engine:

C'est un peu le principe de la bille enfermée dans une boite que l'on secoue de droite à gauche.

Selon les vidéos sur youtube, ce type de propulsion n'aurait besoin d'aucun carburants conventionnels et peut atteindre en théorie 99 pourcents de la vitesse de la lumière (C).


Voici un lien sur le site de la Nasa:

"A new concept for in-space propulsion is proposed in which propellant is not ejected from the engine, but instead is captured to create a nearly infinite specific impulse. The engine accelerates ions confined in a closed loop to relativistic speeds, and slightly varies their velocity to change their momentum. The engine then moves the ions back and forth along the direction of travel to produce thrust. This in-space engine is intended to be used for long-term satellite station-keeping without refueling or to propel spacecraft across interstellar distances. The engine has no moving parts other than ions traveling in a closed-loop vacuum line, trapped inside electric and magnetic fields."
