摘要： An inductive ignition circuit (10) especially adapted for use with micro-turbine and other small-sized turbine engines such as are used in electric generators. The inductive ignition circuit (10) includes a flyback transformer (14), a drive circuit (16) for energizing the primary (22) of the transformer (14), and a control circuit (18) that temporarily disables the drive circuit (16) once the transformer primary (22) has been sufficiently energized. The drive circuit includes a switching transistor (20) which is biased on to draw current through the primary (22). The control circuit (18) includes two feedback circuits (42, 44), one of which initiates disabling of the transistor (20) to cause the transformer flyback and the second of which sets the spark rate. The first feedback circuit (42) monitors the primary current and disables the transistor (20) once the current exceeds a pre-selected level. The second feedback circuit (44) uses a portion of the flyback energy obtained via a feedback winding (30) to maintain the transistor disabled for a period of time that can be selected over a wide range of values. The feedback winding (30) is used to provide positive bias to the transistor (20) during switching on of the transistor and is used by the second feedback circuit (44) during flyback to provide charging current to an RC timer circuit (64) in the second feedback circuit. This timer circuit (64) includes a capacitor (68) which is used to hold the transistor (20) off until the capacitor (68) has discharged below a pre-selected level.

摘要： Igniter and spark plugs according a tubular insulator (12) having an axially extending passage (20) and axially opposed sealing shoulders (30, 32) within the passage (20) spaced from the ends of the insulator (12). A multi-part electrode assembly (14) is disposed within the insulator (12), including an upper electrode (36) joined by resistance welding to a lower electrode (38). A heat-expandable sleeve (40) is carried about the upper electrode (36) and a lower end thereof confronts a compressible gasket (68) and the upper sealing shoulder (30). During resistance welding, the upper and lower electrodes (36, 38) are displaced toward one another causing the gaskets (66, 68) to be compressed against the sealing shoulders (30, 32) of the insulator (12) to form a gas-tight seal therebetween.

摘要： An air-cooled ignition lead for use with aircraft engines to conduct high voltage ignition pulses between an exciter and an igniter. The ignition lead includes a center conductor covered by an insulation jacket for electrical isolation. Radially spaced outwardly from the insulation jacket is a flexible conduit that has sufficient structural integrity to resist collapsing inwardly. The insulation jacket and conduit define an airflow path therebetween that is used for conducting air through the lead. An innerbraid is located over and supported by an outer surface of the flexible conduit, and this location of the innerbraid prevents it from collapsing over time and obstructing the airflow passage that extends on the inner side of the flexible conduit. The innerbraid can be used as a return path conductor that provides a return current path and/or EMI shielding. Covering the innerbraid is an outerbraid to protect the lead against external damage.

摘要： A partitioned exciter system for use with an igniter in an aircraft engine. The exciter has low-energy charging circuit (10) and a high-energy discharge circuit (14) that are remotely located from each other and that are connected by a low-energy coaxial cable (16). The charging circuit can be located within the aircraft fuselage and the discharge circuit mounted at the engine. The discharge circuit contains passive components that do not need special environmental protection, and the remotely located charging circuit can utilize existing electrical circuitry protection measures already in place in the fuselage to protect against lightning and other potentially-damaging environmental factors. Also disclosed is a housing arrangement (70) for the discharge circuit that allows it to be directly attached to the igniter.
