Active flow control (AFC) based on plasma synthetic jet actuator (PSJA) has been attracted a lot of researchers since Anderson and Knight put forward the concept PSJA for first time. Since then characteristic studied by means many numerical simulations experiments. This article showed series studies that manipulated vehicle without moving surfaces. Firstly, we research characteristics aviation ...

Because jet noise consists of extended, partially correlated sources, a multi-wavepacket model is appropriate to simulate jet noise field levels as well as the appropriate spatial coherence properties within the field. Here, the Hybrid method is used to reconstruct the levels and coherence properties of the source region for multi-wavepacket numerical models. The beamforming source results are ...

Airlines are increasingly using regional jets to better match aircraft size to high value, but limited demand markets. This has been especially important following increased financial pressure on the industry after September 11 2001. The increase in regional jets represents a significant change from traditional air traffic patterns. To investigate the possible impacts of this change, this study...

A model of sound generated in an ideally expanded supersonic (Mach 2) jet is solved numerically. Two con gurations are considered; (i) a free jet and (ii) an installed jet with a nearby array of exible aircraft type panels. In the later case the panels vibrate in response to loading by sound from the jet and the full coupling between the panels and the jet is considered, accounting for panel re...

This study examines the usefulness of providing cockpit automation training to career-minded pilots using automation equipment commonly found in small training airplanes. After mastering a set of tasks and maneuvers of varying difficulty using a small-airplane GPS navigation computer, autopilot, and flight director system, eight student pilots were then tested on their ability to complete a sim...

The jet propulsion engine is used for the propulsion of aircraft, m issile and submarine (for vehicles operating entirely in a fluid) by the reaction of jet of gases which are discharged rearward (behind) with a high velocity. As applied to vehicles operating entirely in a fluid, a momentum is imparted to a mass of fluid in such a manner that the reaction of the imparted momentum furnishes a pr...
