The turbine is the main part of aircraft engine responsible for converting fuel into energy to drive propeller blades. article devoted maintenance and repair an turbine, including basic procedures techniques used detect correct defects damage in turbine. It also describes process diagnosing analyzing failures, how prevent such failures from occurring future. Turbine critical flight safety, can ...

An aircraft system noise study is presented for the Blended-Wing-Body (BWB) aircraft concept with three open rotor engines mounted on the upper surface of the airframe. It is shown that for such an aircraft, the cumulative Effective Perceived Noise Level (EPNL) is about 24 dB below the current aircraft noise regulations of Stage 4. While this makes the design acoustically viable in meeting the ...

To design better aircraft and engines, co-operation is of prime importance. In aircraft design Co-operation has many facets, such as the involvement of experts in various disciplines that work together and share their specific knowledge. Often such experts are employed by different companies and are thus geographically dispersed. The early phases in, for instance, aircraft wing design allow muc...

Self-tuning aircraft engine models can be applied for control and health management applications. The self-tuning feature of these models minimizes the mismatch between any given engine and the underlying engineering model describing an engine family. This paper provides details of the construction of a self-tuning engine model centered on a piecewise linear Kalman filter design. Starting from ...

Environmental concerns have led to a growing effort to investigate and characterize the particulate matter (PM) emissions from aircraft engines. This thesis presents a onedimensional microphysics and chemical kinetics model that is used to study the formation and evolution of particulate matter in near field aircraft plumes at ground level. The initial exhaust properties were obtained from engi...

This paper presents GeoMACH: Geometry-centric MDAO of Aircraft Configurations with High fidelity. GeoMACH is an open-source aircraft design tool suite under development that is planned to support MDAO with a large number of design variables. First, the overall GeoMACH architecture is described, including a proposed method for streamlined data transfer between disciplines. GeoMACH’s efficient an...

The development of persistent contrails was modeled to determine the sensitivity of their climaterelevant properties to various parameters. Optical depth and area coverage varied most strongly with vertical shear. For a 4-engine aircraft and 130% ambient relative humidity with respect to ice, a moderate shear of 0.005 s−1 reduced the peak depth by 79% and increased the coverage by 450% after tw...
