A pulsed combustion apparatus includes a conduit having an outer wall and an inner wall. The inner wall has a number of apertures. An interior space is separated from the outer wall by the inner wall. An induction system is positioned to cyclicly admit charges to the interior space. An ignition system is positioned to ignite the charges. Flow directing surfaces are positioned to at least cyclicly direct cooling air through the apertures.

A pulsed combustion device includes a support structure and a combustor carousel supported by the support structure and rotating relative thereto about an axis. The carousel has a number of combustion conduits in a circumferential array. Each conduit cyclically receives a charge and discharges combustion products of the charge.

A fan-turbine rotor assembly (24) includes a multitude of turbine blades (34) which each define a turbine blade passage which bleed air from a diffuser section (74) to provide for regenerative cooling. Regenerative cooling airflow is communicated from the radial core airflow passage (80) through the diffuser passages (144), through diffuser aspiration passages (146A, 146B) and into the turbine blade passages (150a). The regenerative cooling airflow exits from the turbine blade passage (150a) and transfers received thermal energy into an annular combustor (30). The received thermal energy is recovered at the highest temperature in the cycle.

A tip turbine engine comprises a fan-turbine rotor assembly that includes one or more turbine ring rotors. Each turbine ring is assembled from a multitude of turbine blade clusters. Assembly of a multitude of turbine blade clusters to a diffuser includes axial installation and radial rotation. The clusters are axially installed, then rotated toward a radial stop in a direction which will maintain each cluster against the radial stop during operation of the fan-turbine rotor assembly. A multitude of turbine rotor ring stages may also be locked together to future increase the rigidity of the turbine

A fan-turbine rotor assembly includes a diffuser mountable to the outer periphery of a multitude of fan blade sections to provide structural support to the outer tips of the fan blade sections and to turn and diffuse the airflow from the radial core airflow passage toward an axial airflow direction. The diffuser includes a fan blade tip shroud inner portion which forms a planar ring about the multiple of fan blade sections. Diffuser support rings are mounted to the fan blade tip shroud to further share the radial load applied to the fan blade sections by the blade mounted diffuser and annular turbine.

A fan-turbine rotor hub includes an outer periphery scalloped by a multitude of elongated openings. Each elongated opening defines an inducer receipt section to receive an inducer section and a hollow fan blade section. An inducer exit from each inducer section is located adjacent a core airflow passage within each fan blade section to provide communication therebetween. A seal is located between an inner fan blade mount and a blade receipt section to minimize airflow leakage between the inducer exit and the core airflow passage.

A method and system for configuring one or more prospective-participant nodes as participant nodes so as to enable the prospective-participant nodes to engage in a peer-to-peer communication is provided. In one exemplary embodiment, the method and system may be embodied as a common application that includes logic, in hardware or software form, for carrying out one or more of the functions for configuring one or more prospective-participant nodes as a participant node in a peer-to-peer network.In carrying out these functions, one of the participant nodes discovers its network-connection settings, and based on these settings, generates participant-node-configuration data that includes one or more network connection settings that define how to address the prospective-participant node as a participant node.When desiring to join the peer-to-peer network, the prospective-participant node and the participant node may establish a point-to-point communication link by engaging in a discovery process using so as to establish a data-link layer connection. After completing negotiation of the data-link-layer connection, the prospective-participant node and the participant node may communicate over the data-link-layer connection.The prospective-participant node may send to the participant node a request for network access. Responsively, the participant node sends to the prospective-participant node the participant-node-configuration data over the point-to-point connection. And the prospective-participant node configures itself using the participant-node-configuration data so as to become a participant node.
