2008 DEC 8 - (VerticalNews.com) -- "A flight test of a supersonic experimental airplane (National Experimental Supersonic Transport, NEXST-1) was successfully conducted by the Japan Aerospace Exploration Agency in October of 2005. The experimental airplane was designed to reduce drag on supersonic cruise condition by means of some conventional and advanced design concepts: arrow wing planform, warp wing, area-ruled body, and natural laminar flow wing," scientists in Tokyo, Japan report ...read more

  2008 MAR 17 - (VerticalNews.com) -- According to a study from the United States, "The U.S. Army Aeroflightdynamics Directorate (AFDD), the French Office National d'Etudes et de Recherches Aerospatiales (ONERA), and the Georgia Institute of Technology (GIT), through the United States/France Memorandum of Agreement on Helicopter Aeromechanics, have performed a comparative study of the Dauphin 365N helicopter to analyze the capabilities and weaknesses of state-of-the-art computational fluid dynamics (CFD) codes, with the aim of fuselage performance prediction and initial investigation of rotor-fuselage interaction. ...read more

  2008 MAR 17 - (VerticalNews.com) -- According to recent research published in the Journal of the American Helicopter Society, "In this study, three types of flight maneuvers, namely arrested descent, turns, and roll-reversal maneuvers, were examined using a rotorcraft aeroacoustics prediction model. Components of the model comprised a utility helicopter flight dynamics model, a time-accurate free-vortex rotor wake model, and a maneuvering rotor noise prediction code. ...read more
