CDI is located at 34 Lexington Avenue, Ewing, New Jersey and occupies over 12,000 square feet of office and laboratory space. To support computational studies, the company owns and operates a cluster of five dual-processor Intel Xeon 3 GHz machines and a Silicon Graphics, Inc., Altix 12-processor system. A network of over 25 Intel-based personal computers is also available to support engineering analysis and simulation calculations. On-site experimental facilities include a 1'x1' low turbulence wind tunnel with a maximum speed of 150 fps; this tunnel is capable of a range of studies, from very low turbulence testing of vortical flows to proof of concept demonstrations of advanced aeronautical devices.

CDI also owns and operates several static rotor/propeller test stands, including an outdoor stand for rotors and other rotating models up to 6 feet in diameter. The stand is driven by a 15 HP electric motor and includes an 8 channel slip ring to record on-blade data.  Outdoor hover stand (left); view of flapped airfoil model (right).

Other facilities in hand for the study of small rotor/propeller performance include thrust stands for measurement of forces and moments on UAV-class propulsion components.  Thrust stand with a small UAV propeller (left); rotor stand with a four-bladed rotor for a micro helicopter (right). In addition, CDI owns and operates a 24" low speed water tunnel (below left) used for basic studies in fluid mechanics as well as engineering demonstrations of devices for naval applications (e.g., the variable geometry duct below right) and the hydraulics of power generation systems. 
Finally, the CDI thermal hydraulics laboratory includes numerous unique testing rigs for studies of acoustic resonances in piping systems, fluid/structure interactions in steam/water flows, and head loss in advanced debris strainer designs for nuclear power plant applications. |
