Classically trained engineers have been left with the impression it is impossible to control 100% of the torque generated by a single lift rotor, using only the downdraft, within the same diameter as the lift rotor, because 100% of the torque minus 100% of the torque would leave no useable downdraft. This illusion has stymied the development of a torque control system with many potential applications. The TSVLS torque control system solves the problem by locating a lift rotor over vertical airfoils arrayed within a shroud to create “horizontal lift” in an anti torque direction.

Our testing shows 100% of the torque can be controlled, balanced, with anti torque forces, even while the airfoils are at a low angle ...

A Levitated Annular Rotor System (LARS) is proposed to power and propel ultra-heavy vertical lift air vehicles in commercial and military markets. LARS is an invention derived from a conceptual redesign of the helicopter made possible by advancements in electromagnetic motor and energy storage/transport technology. It exploits advances across multiple fields of physics to include electromagnetism and high temperature superconductivity. LARS research aligns with NASA's roadmap for vertical lift technology and Urban Air Mobility.

LARS uses a scalable electromagnetic tip drive design that imparts mechanical torque to a rotor blade assembly within the confined space of the system annulus. The rotating blade assembly is magnetically suspended to minimize frictional energy loss. Comparatively, LARS’ integrates the disparate functions of a helicopter’s ...
