The gas turbine-based propulsion systems were responsible for the emission of pollutants that damage ecosphere. Commercial aviation represented a large portion carbon emissions within industry, so this study focused on novel aircraft commercial aircraft. Electric was considered to be an alternative conventional systems. Therefore, report analyzed various electric concepts aerospace industry see...

Kalman filters are often used to estimate the state variables of a dynamic system. However, in the application of Kalman filters some known signal information is often either ignored or dealt with heuristically. For instance, state variable constraints (which may be based on physical considerations) are often neglected because they do not fit easily into the structure of the Kalman filter. This...

This paper deals with evaluation and analysis of carbon footprint an airline operator, Nepal Airlines Corporation (NAC) by using its actual flight maintenance data from 2016 to 2019. NAC is a multi-fleet both turboprop turbofan aircrafts. Carbon in terms Dioxide (CO2) emission has been calculated for NAC’s operations per individual aircraft, fleet-type operating sector (i.e., international dome...

This study involves the application of fan flow deflectors for suppression of jet noise from low-bypass turbofan engines for next-generation supersonic aircraft. Experiments using canonical vane deflectors seek to establish correlations between aerodynamics, distortion of the mean velocity field in the jet plume, and noise reduction. The maximum radial velocity gradient, as a function of axial ...

Model predictive control is a strategy well-suited to handle the highly complex, nonlinear, uncertain, and constrained dynamics involved in aircraft engine control problems. However, it has thus far been infeasible to implement model predictive control in engine control applications, because of the combination of model complexity and the time allotted for the control update calculation. In this...
