  • Continuum Dynamics, Inc. at the 67th AHS Annual Forum


  • CDI has just completed its 12th consecutive annual visit to the American Helicopter Society Forum, held May 2-4 in Virginia Beach, VA. The technical display at our booth echoed the theme of the meeting: "Catching the Wave of New Vertical Flight Technology". The central feature of the display was a fixed-base flight simulation using the CHARM real time Wake/Panel Module to model an H-60 helicopter in shipboard operations. The Module permits real-time turnaround for piloted simulations including full free wake and realistic deck effects. It was coupled into the U.S. Navy CASTLE flight simulation environment, and built on ongoing work for the Navy led by Dan Wachspress and Jeff Keller of CDI.

    The display also provided an overview of other CDI technologies, including the CHARM, VorTran-M, MAST, and Brownout product lines while also featuring success stories from the application of these and other tools to flight simulations, fielded rotorcraft systems and prospective next-generation vehicles.

    CDI staff were also active at the meeting, with three staff members - Bob McKillip, Michael Yu, and Glen Whitehouse - chairing technical sessions. A total of five technical papers, spread across the Aerodynamics, Flight Simulation, and Advanced Vertical Flight sessions, were presented by CDI personnel.





  • CDI Ship Air Wake Development Featured in Tecplot Case Study


  • Every month, Tecplot Inc., the company behind the Tecplot family of visualization and plotting software, publishes a case study describing exciting new applications of their tools. For the March 2011 edition, Tecplot featured CDI's VorTran-M software and the development of the ship air wake database for the US Navy's MH-60R tactical trainer.

  • CDI led research on flapping wing aerodynamics featured in mainstream and online scientific press


  • Breakthrough research led by Continuum Dynamics, Inc. and New Mexico State University, investigating the influence of gusts on the aerodynamics of flapping wings was recently featured in the mainstream and online scientific press. This work, funded by the U.S. Air Force Research Laboratory through the Small Business Technology Transfer Program, advanced the fundamental understanding of the relationship between flapping wing kinematics and forces in still and gusty environments with the ultimate goal of developing aerodynamic/aeroelastic models for use in the design and analysis of flapping wing Micro Air Vehicles.

  • 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.
