Abstract: A frame for the support of a bladed array, such as a compressor rotor stage or turbine rotor stage for turbo machinery, comprises a collar configured to fit around a radially outer periphery of the array. The collar is provided with a closure mechanism. The closure mechanism is configured to, in use, close the collar around the bladed array such that at least part of at least some of the blades are engaged with and/or captured by the radially inner surface of the collar. The collar and bladed array are held in a fixed relationship relative to one another.

Abstract: Configuration of hardware and software onboard a mobile platform may be dynamically managed without significantly impacting a data stream from the mobile platform. Configuration data for equipment and resident software aboard a mobile platform is electronically reported in the form of a part number and a serial number. The configuration data is transferred to a terrestrial database via a mobile communications network. The configuration data is displayed to stakeholders, such as the network-provider enterprise and its customers. Invalid configurations may cause alerts.
