CDI Teams with Flow Analysis Solutions, Inc.
Flow Analysis Solutions, Inc. (FAS)
of New York NY has teamed with CDI to provide rotorcraft industry
users with software products based on the Vorticity Confinement (VC) methodology pioneered by Dr. John
Steinhoff.
Software that will allow users of current-generation CFD and comprehensive codes to seamlessly integrate the
advanced wake and body modeling capabilities of VC into their analyses will be released in the first half of 2010.
Technical background on VC methods and applications are available at the
FAS website. FAS can also
be contacted through their site for details on the projected products as well as the terms of trial and full licenses.

CDI Awarded Alfred P. Gessow Best Paper Award of AHS Annual Forum 65, Dallas, Texas, May 27 - 29, 2009
CDI's brownout paper, entitled "A High Fidelity Brownout Model for Real-Time Flight Simulations and Trainers" by Daniel
Wachspress, Glen Whitehouse, Jeff Keller and Michael Yu of CDI and collaborators at SAIC at Redstone Arsenal has won "Alfred P. Gessow Best Paper Award" of AHS Annual Forum 65.

CDI Voted Best Paper in Simulation, and Overall Best Paper Nominee at I/ITSEC 2008
The Interservice/Industry Training Simulation and Education Conference (I/ITSEC) was held at the Orange County Convention Center in Orlando, FL on Dec. 1-4, 2008,
and was attended by over 18,000 industry and government professionals and featured cutting edge technology in the rapidly growing fields of training and simulation.
CDI sponsored a booth in the exhibit hall for the second time at this prestigious meeting, and provided technology demonstrations and technical briefings, including
two technical papers describing advanced brownout simulations and the use of CDI's CHARM real-time free-vortex wake model for the prediction of rotorcraft aerodynamic
effects in a shipboard environment. CDI's brownout paper, entitled "Physics Based Modeling of Helicopter Brownout for Piloted Simulation Applications" by Daniel
Wachspress of CDI and collaborators at SAIC at Redstone Arsenal was voted "Best Paper" in the Simulation session and was nominated for "Best Paper" overall.

CDI Featured in NASA Spinoff Magazine
CDI's CHARM rotorcraft analysis is a featured commercial product in NASA's Spinoff 2007 — NASA's annual premier publication featuring successfully commercialized
NASA technology. Spinoff features between 40 and 50 commercial products annually.

I/ITSEC Symposium in Orlando 2007
The Interservice/Industry Training Simulation and Education Conference (I/ITSEC) was held at the Orange County Convention Center in Orlando, FL on Nov. 26-29, 2007.
CDI sponsored a booth in the exhibit hall for the first time at this prestigious meeting, which was attended by over 16,000 industry and government professionals
and featured cutting edge technology in the rapidly growing fields of training and simulation. CDI provided technology demonstrations and technical briefings,
including a technical paper prepared by Jeff Keller of CDI and his collaborators at CAE describing the use of the coupled CGE/ VorTran-M model for the computational
modeling of ship airwakes for use in simulation databases. Technical demonstrations introduced attendees to this software as well as variety of additional tools and
technologies, including the use of CDI's CHARM real-time free-vortex wake model for prediction of rotorcraft aerodynamic effects in a shipboard environment as well
as novel physics-based modeling of rotorcraft brownout.
Look for future CDI technology displays at the American Helicopter Society 64th Annual Forum (April 29-May 1, 2008 in Montreal, Canada) as well as the the U.S.
Navy 2008 Opportunity Forum at the Hyatt Crystal City, VA (June 2-4, 2008).
CDI's composite blade design in action
A Carson Helicopters S-61 waterbomber fights the 2007 California wildfires using new high performance composite blades designed by Carson in collaboration with CDI
personnel. These new blade sets are also already in service in Afghanistan with UK armed forces on Westland Sea King helicopters, and will enter service as an upgrade
to the U.S. Navy VH-3D fleet of Presidential transport helicopters in 2008.
CDI's work in rotor analysis supports Sea King featured in "Defense Helicopter"
As part of a multi-year effort sponsored by Carson Helicopters in the 1990s, CDI undertook the analysis of improved rotors for civil S-61 helicopters operated by Carson.
This activity exploited the fast, accurate design capability afforded by the CDI EHPIC-HERO software
. Carson subsequently fabricated and flight tested their new rotor blade design, as detailed in a a 2002 paper
presented at the American Helicopter Society Annual Forum. As noted in that paper, the CDI analysis accurately predicted the measured rotor performance
improvement (including an 8 point increase in hover Figure of Merit, corresponding to a 10% increase in gross lift at constant power) several years prior to flight test.
Carson is now selling these rotor blades to commercial operators worldwide, but also has customers in the both the U.S. Navy and the U.K. Royal Navy. The new blades
are being installed on U.S. Navy SH-3D helicopters used for Presidential/Executive transport missions, while the
attached article describes how U.K. Sea King (SH-3 derivatives) using the new rotors are already entering service in Afghanistan.
