Latest Patents

Brown's latest patents focus on the development of variable geometry turbines. The first patent describes a turbine wheel supported in a housing for rotation about a turbine axis. This design features an annular inlet passage defined between first and second radial inlet surfaces, with one surface being defined by a moveable wall member. The turbine includes a substantially annular array of vanes that extend across the inlet passageway, each fixed to the first inlet surface. The vanes are designed with first and second major surfaces that enhance their aerodynamic efficiency.

The second patent also pertains to a variable geometry turbine, which includes a nozzle ring that is moveably mounted within a cavity in the housing. This allows for the adjustment of the width of the annular inlet passageway extending radially inwards towards the turbine wheel. An array of inlet guide vanes is integrated into this design, providing improved fluid communication through strategically placed apertures.
