Patent number: 9557050Abstract: A nozzle for assemblies and gas turbines is provided. The nozzle exhibits destabilized flame holding characteristics, i.e., the nozzle is unable to stabilize flame up to an equivalence ratio of about 0.65. As a result, flame heat release is delayed resulting in lower peak flame temperatures and correspondingly lower NOx levels. Flame stabilization capability is retained for higher equivalence ratios to support operation of the combustor in other regions of the load range.Type: GrantFiled: July 30, 2010Date of Patent: January 31, 2017Assignee: General Electric CompanyInventors: Christian Lee Vandervort, Joel Meier Haynes

Patent number: 7841167Abstract: An engine contains at least one pulse detonation combustor which is surrounded by a bypass flow air duct, through which bypass air flow is directed. The bypass air duct contains at least one converging-diverging structure to dampen or choke the upstream propagation of shock waves from the pulse detonation combustor through the bypass flow air duct. The bypass air also serves to cool the outer surfaces of the pulse detonation combustor. The bypass air flow is controlled in tandem with the heat release from the PDC to provide the appropriate amount of thermal energy to a downstream energy conversion device, such as a turbine. A mixing plenum is positioned downstream of the pulse detonation combustor and bypass flow air duct.Type: GrantFiled: November 17, 2006Date of Patent: November 30, 2010Assignee: General Electric CompanyInventors: Adam Rasheed, Anthony John Dean, Peirre Francois Pinard, Christian Lee Vandervort, Venkat Eswarlu Tangirala
