A method, apparatus, system, and computer program product for evaluating a maturity of a model for a product. A selected maturity state is determined by a computer system for the model for evaluation. A determination is made by the computer system as to whether the model meets a set of criteria for the selected maturity state and a confidence level for the selected maturity state. A model action is performed by the computer system using the model when the model meets the set of criteria for the selected maturity state and the confidence level for the selected maturity state.

Model maturity state evaluation system

A coupling assembly that connects first and second conduits and prevents a fluid from leaking from a junction formed between the first and second conduits. The coupling assembly includes an inner coupling and an outer coupling that extends around and connects the first and second conduits. A retention strap extends around the first and second conduits and is positioned between the inner and outer coupling.

Coupling assembly to connect first and second conduits

An aircraft engine system has a turbofan engine with a lubricating oil system. An oil pump is connected to pump oil from the oil tank through a cooling circuit to the turbofan engine. The cooling circuit has a bleed air boosted engine oil cooler assembly with a liquid/air heat exchanger (LAHEX) connected to an oil inlet conduit and receiving fan air from a high bypass fan of the turbofan engine as the cooling working fluid. The LAHEX is connected to an oil exit conduit. An ejector downstream of the LAHEX receives bleed air from a compressor section of the turbofan engine. The ejector draws the fan air through the LAHEX.

Drainage devices intended to prevent the reentry of drained fluids, the devices including a base having a contact surface for mounting over a drainage opening in an aerodynamic surface, a mast portion connected to the base and extending away from the contact surface of the base, and a top portion connected to the end of the mast portion, the top portion having a periphery that is greater than the periphery of the mast portion and including an exit port. The top portion may include a cantilevered fence portion extending upstream relative to the aerodynamic surface, and the drainage devices may be part of a system including a first opening and a second opening in the aerodynamic surface, the second opening upstream from the first opening, where a drainage device is mounted over the first opening and the cantilevered fence portion of the drainage device extends upstream toward the second opening.
