ALM's 50...500kW Engine Design
The ALM Turbine: A New Approach
ALM has developed a new approach to increasing efficiency and performance over conventional microturbines. Conventional methods of improving efficiency rely principally on using advanced materials to increase turbine inlet temperatures.
ALM has achieved a number of technological breakthroughs including the development of a novel combustion technology and combustor design, a novel blade cooling technology and the adoption of a novel semi-closed cycle.
To reduce costs and increase performance, ALM has also eliminated a number of expensive components including stator vanes between the two stages, nozzles between its combustor and turbine, fuel injectors and catalytic converters and devices.
Another ALM innovation is to control the power of a turbine by varying the density of the working fluid. Along with its semi-closed cycle, this approach allows the ALM engine to achieve high efficiencies over a broad load and speed range and fast response to sudden load and speed changes.
ALM's technology can be applied to both power generation/industrial applications as well as vehicular applications.
ALM has designed a viable automotive engine, addressing the problems of all prior automotive gas turbine programs. ALM automotive engine has the following characteristics:
Due to its direct drive capabilities and stable efficiencies at part load, the ALM engine is ideal for a parallel hybrid or "power assist" applications.
ALM's technology platform is highly conducive to further increases in efficiency over time.
