Continuum Dynamics

Continuum Dynamics, Inc. (CDI) is a research and development firm in Ewing, New Jersey, serving government and industry. It was founded in 1979 by Dr. Alan J. Bilanin and describes more than forty years of contract R&D, software development and licensing, engineering and design, and test support. Aerospace, environmental and nuclear engineering are among its areas, and rotorcraft is a major focus.

Rotorcraft work

• Rotorcraft aerodynamics, wake mechanics and interactional aerodynamics
• Helicopter brownout and particle transport near rotorcraft
• Rotor blade design and optimization, with blade designs cited as in operation worldwide including on the VH-3D Marine One
• Low noise flight procedure analysis
• Flight dynamics, simulation and control
• Design support for urban air mobility and distributed electric propulsion vehicles

Products

CHARM (Comprehensive Hierarchical Aeromechanics Rotorcraft Model) is the flagship product. It models the full aerodynamics and dynamics of helicopters, VTOL aircraft and multirotors in general flight conditions, and links to the PSU-WOPWOP noise analysis tool. The Sim Modules are real time versions derived from CHARM for flight simulators and trainers, including wake and panel, blade and aero, multiple aircraft (MAST) and brownout modules. CDI also lists CGE, a Cartesian CFD solver with an actuator disk rotor model, and FJSIM for fuel jettison.
