Gilles Saint-Hilaire on the Quasiturbine Engine

September 22, 2012| Engines|1 Minutes|By AAG

Most physicists don’t spend their vacations designing engines, but Dr. Gilles Saint-Hilaire isn’t like most physicists. After a thorough study of the limitations in most conventional engines, he designed the Quasiturbine Engine – a next generation 4-blade rotary turbine and future plans for a high-efficiency photo-detonation engine with the potential to revolutionize the automotive industry..

“For 200 years, everyone had assumed that sinusoidal crankshaft movement was the best way to convert linear motion (like a piston) to rotary motion, but nobody had actually proved it in relation to combustion. A closer look at the gas flow and combustion process has taught us that in reality, the sinusoidal crankshaft has actually been a major obstacle to the development of modern optimized engines. In contrast, the Quasiturbine design allows us to shape in time the volume pulse in the combustion chamber, which is something that a piston or Wankel engine simply can’t do. This really optimizes the thermodynamic efficiency for the Quasiturbine combustion-cycle.

Just like the early years with piston engines, our first step in is toward pneumatic (air) and steam engines (quite a large industry), followed by Quasiturbine “Beau de Rocha” (Otto-cycle) combustion engines and ultimately by a photo-detonation design — an extremely efficient and clean mode of operation.” – Dr. Gilles Saint-Hilaire
