RISDesign, Evaluation and Performance Analysis of Staged Low Emission Combustors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The most uncertain and challenging part in the design of a gas turbine has long been the combustion chamber. There has been a large number of experimentations in industry and universities alike to better understand the ...
Optimization of Aero Gas Turbine Maintenance Using Advanced Simulation and Diagnostic Methods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Engine maintenance costs are a major contributor to the direct operating costs of aircraft. Therefore, the minimization of engine maintenance costs per flighthour is a key aspect for airlines to operate successfully under ...
Validation and Assessment of a Hybrid VOF-Lagrangian Numerical Methodology for Turbulent Liquid Fuel Jets in High-Speed Crossflow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For gas turbine combustors, injecting liquid fuel in crossflow can achieve superior mixing characteristics to improve performance and reduce emissions. Robust numerical design tools are needed to accelerate the development ...
Computational Fluid Dynamics Investigation of a Core-Mounted Target-Type Thrust Reverser—Part 2: Reverser Deployed Configuration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Core-mounted target-type thrust reverser (CMTTTR) design was proposed by NASA in the second half of the 90 s. NASA carried out several experiments at static conditions, and their acquired results suggested that the performance ...
Computational Fluid Dynamics Investigation of a Core-Mounted Target-Type Thrust Reverser—Part 1: Reverser Stowed Configuration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During the second half of the 90 s, NASA performed experimental investigations on six novel thrust reverser (TR) designs; core-mounted target-type thrust reverser (CMTTTR) design is one of them. To assess the CMTTTR ...
Preliminary Design Framework for the Power Gearbox in a Contra-Rotating Open Rotor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Geared contra-rotating open rotors have the potential to further reduce fuel consumption relative to geared turbofans, but require a more-complex speed-reducing transmission system to drive the propellers. Hitherto, the ...
