Taking PDE Development to Next Level

PNGinc's Pulse Detonation Turbine tests show performance gains

Munising, MI - Testing of PNGinc's pulse detonation disc turbine technology had the lab radiating with excitement today. By closely tuning the entire system, R&D chief Ken Rieli succeeded in significantly improving turbine performance over initial tests held on January 23rd.

Now in proof-of-principle stage, the PDT (pulse detonation turbine) couples the company's proprietary pulse detonation combustor technology to a small Tesla type disc turbine.

Serbian-American inventor Nikola Tesla first built and tested his own pulse detonation turbine with valvular conduits in the 1920's. In more recent times, PNGinc has experimented with the characteristics of disc turbines, blade geometry, steady state fluids, and combustion models. Building upon their work in developing low-cost turbines for solar steam and biomass/waste product steam applications, the company is now concentrating on a new type of gas turbine.

As global warming heats up, and air pollution chokes our skies, the ultimate prime mover -- a new gas turbine to replace the worn out piston internal combustion engine -- is now under development.
