Irving Segalman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Gas turbine combustor heat shield panel or exhaust panel including a cooling device
    Patent number: 7464554
    Abstract: A combustor heat shield panel has interior and exterior surfaces with a number of circuitous non-interconnected cooling gas passageways having inlets on the exterior surface and outlets on the interior surface.
    Type: Grant
    Filed: September 9, 2004
    Date of Patent: December 16, 2008
    Assignee: United Technologies Corporation
    Inventors: Albert K. Cheung, Nikolaos Napoli, Irving Segalman
  • Gas turbine annular combustor having a first converging volume and a second converging volume, converging less gradually than the first converging volume
    Patent number: 7093441
    Abstract: A gas turbine engine combustor has inboard and outboard walls. A forward bulkhead extends between the walls and cooperates therewith to define a combustor interior volume. In longitudinal section, a first portion of the combustor interior volume converges from fore to aft and a second portion, aft of the first portion converges from fore to aft more gradually than the first portion.
    Type: Grant

  • Low NOx combustor for gas turbine engine
    Patent number: 6240731
    Abstract: A method of combusting fuel in the combustor of a gas turbine engine is disclosed which includes injecting fuel and a first predetermined amount of airflow into the combustion chamber to form a fuel-rich, highly mixed, uniform distribution fuel-air spray pattern flowing downstream in the combustion chamber and introducing a second predetermined amount of airflow into the fuel air spray pattern from combustor air inlets positioned at a first predetermined distance downstream from the combustor dome with the first predetermined distance being greater than 0.75 times the dome height and said second predetermined amount of airflow being sufficient to cause rapid mixing and quenching of the rich fuel-air mixture to a lean fuel-air mixture.
