Recently cited by Forbes magazine as “the coolest business jet ever”, the Falcon 7X is the latest in a long line of high-class executive jets from Dassault Aviation. As well as being cool, the Falcon 7X is also revolutionary - being the first civil aircraft ever to be designed using virtual rather than physical prototypes. Designed entirely using Dassault Systèmes CATIA Product Lifecycle Management (PLM) tools, every component on the Falcon 7X was subjected to rigorous CAE analyses.

As engineers routinely applying CFD to a wide range of turbomachinery and aerospace applications, we often face technical judgments as to the applicability of certain numerical approaches or physical models used in a simulation. One such judgment for rotating machinery relates to the choice of either applying a time accurate transient moving mesh approach or a simplified steady-state multiple rotating frames (MRF) approach. This modeling decision can be critical especially when simulating the flow through rotating systems which contain a low blade count. Aerospace Special Report #1: Read more...
D.Funda Kurtulus 1,2, Alain Farcy 1, Laurent David, Nafiz Alemdaroglu Ecole National Superieur de Mechanique et d’Aérotechnique, LEA, Poitiers, France Middle East Technical University, Ankara Turkey The aim of the flapping airfoil analysis is to understand the aerodynamic phenomena and the vortex topology of this highly unsteady motion. Instead of the use of real insect/bird wing geometries and motions, which are highly complex and difficult to imitate by a exact modeling, a simplified model is used to understand the unsteady aerodynamics and vortex formation during the different phases of...
The challenge of designing a next generation compact Vertical Take Off and Landing (VTOL) craft has been addressed with the combination of a novel radial fan technology and the use of unique lifting and control surfaces. Aerospace Special Report #1: Read more...
For over a century mankind has devoted substantial resources toward achieving and improving flight. With the yearly threat of major wildfires and the ongoing conflicts in the Middle East as its primary focus, Propulsive Wing, LLC is developing unmanned aerial vehicle solutions for both domestic fire fighting support and military applications, covering a wide range of missions.

The Pro Obser ver Unmanned Aerial Vehicle (UAV) sounds like something straight from the pages of a James Bond story: a miniature aircraft, weighing less than a bag of a sugar, that can be stored in a suitcase, ready to be launched on a “spying” mission within minutes of being unpacked.

UAVs have been used in a reconnaissance & intelligence-gathering role since the ‘50s & more challenging roles are envisioned for the future - including combat missions. Since 1964 the US Defense Department has developed 11 different UAVs, though due to acquisition & development problems only three have entered production. Aerospace Special Report #1: Read more...
Dr. Ulf Specht - IABG mbH, Germany In full-scale fatigue testing of large aircraft, detailed information about the individual test apparatus can be used to optimize operation: saving both time and money! Such in-depth analyses can be dealt with easily and quickly using CFD, yielding much greater detail and understanding than from an experimental investigation alone.

David L. Vaughn - CD-adapco Whether it is lean manufacturing, six sigma, or some combination, quality improvement is now a primary focus of virtually every manufacturer in the aerospace industry. And now that the waste is squeezed out and quality is designed into manufacturing processes, visionary corporations are looking upstream toward the engineering of the product for further gains in quality. One of the keys to ensuring manufacturability and efficient integration of component systems is the implementation of high fidelity Computer Aided Engineering (CAE) software during the early design...
David L. Vaughn - CD-adapco Engineers in the Aerospace industry continue to adopt STAR-CCM+ at an unprecedented rate. Since its launch, STAR-CCM+ has consistently grown in popularity in every facet of the Aerospace Industry. From UAVs to mega-airliners and from avionics cooling to hypersonic re-entry, or ganizations and companies such as NASA, Gulfstream Aerospace, Lockheed Martin, Airbus, Raytheon, MBDA, and many others have standardized on CD-adapco engineering simulation for a variety of applications.
