    摘要： A method of designing an outer air seal for the turbine blades of a gas turbine engine utilizes a knowledge-based product model software program for generating a parametric, three-dimensional, geometric model of the air seal. The product model software program is embodied in a knowledge-based engineering system. The model is created by the program through user selection of various structural feature options available for the air seal. The product model software program uses its internal knowledge base of configuration dependent parameter relationships and rules to design the model. Various types of analyses may then be run to validate the model. The model may be changed, if necessary, as a result of the analyses. The air seal model output from the product model software program is in a file format that defines the topology and dimensions of the geometry of the air seal. Other software programs may then use this product model output file in various ways, such as to re-generate the model for use in a CAD system.

    摘要： A method and system for designing a low pressure turbine shaft comprising the steps of creating a low pressure turbine shaft knowledge base of information. The knowledge base has a plurality of design rule signals with respect to a corresponding plurality of parameter signals of associated elements of a low pressure turbine shaft, wherein the knowledge base comprises at least one data value signal for each one of the plurality of design rule signals. The steps also include entering a desired data value signal for a selected one of the plurality of parameter signals of an associated element of the low pressure turbine shaft and comparing the entered desired data value signal for the selected one of the plurality of parameters with the corresponding at least one data value signal in the knowledge base for the corresponding one of the plurality of design rule signals. If the result of the step of comparing is such that the entered desired data value signal for the selected one of the plurality of parameter signals is determined to have a first predetermined relationship with respect to the corresponding at least one data value signal in the knowledge base for the selected one of the plurality of design rule signals, create signals representative of a geometric representation of the selected one of the plurality of parameter signals of the associated element of the low pressure turbine shaft.

    摘要： The deaerator includes a chamber that includes vortex generators that centrifuge the oil/air to separate the components and the chamber may operate in all attitudes. In addition wake separators mounted in the inlet of the chamber remove a large percentage of the air from the oil prior to entering the chamber and reintroduce the separated air component in the air removal tube. A dam in the air removal tube is located downstream of the inlet of the wake separated air to assure no oil is extracted from the air tube leaving the chamber. The wake separator consists of one or more tubes extending transversely to the flow of the oil/air stream and the air is removed through rearwardly facing apertures formed in the tube(s).
