performance analysis of jet engines in various environmental conditions is important and is the first step in the design of such engines. in this paper, the performance of a typical turboprop engine was modeled in the commercial software gasturb10 and the obtained results are validated at three flight regimes take off, military and 100% normal using engine test results. performance analysis of ...

The paper develops the argument that the long-term structural evolution of an industry depends on the evolution of a vertically-related, downstream industry. We analyse two pairs of vertically-related industries, the jet and turboprop aircraft and engine industries, since the first introduction of the jet and turboprop technologies to 1998. The paper shows that the evolutionary dynamics of the ...

The noise levels in the passenger cabin of turbopropeller-driven aircraft are typically higher than the noise levels in comparable turbofan-powered aircraft. The sources of noise in a turboprop aircraft include boundary layer flow noise, structure-borne noise due to engine vibration, and acoustic excitation of the fuselage due to the propeller, with the latter being dominant for most turboprop ...

Introduction PROPELLER [1] and Turboprop DWI [2] have shown advantages over traditional EPI DWI which include higher resolution, relative insensitivity to motion and robustness to off-resonance. In this work, we propose a new sequence dubbed TURBINE (TURBoprop IN Elevation), which adapts the TurboProp scheme to 3D DWI imaging. The potential benefits of this approach over EPI and turboprop inclu...
