- Vacuum Test Facility (VTF) - The 450-square-foot VTF is designed to support ongoing research and educational activities requiring a controlled vacuum environment. The cornerstone of this facility is a 50-inch diameter, 72-inch long stainless steel vacuum chamber which enables the creation of a vacuum environment for use in the characterization of electric and chemical thruster performance, investigation of neutral and ionized gas plume expansion in a vacuum, and testing of avionics for nanosatellites designed to operate in a vacuum environment.
The pumping system for the VTF includes a rotary mechanical pump, positive displacement blower combination capable of providing substantial pumping speed (> 560 liters/sec ) at low vacuum (10-2 - 10-3 Torr). This pump pair can be used for tests requiring relatively high mass flow rates, such as plume measurements on micro-chemical thrusters.
For tests of electric thrusters where lower pressures (higher vacuum) are required, the mechanical pump would be used initially to pump the system down to the milli-Torr pressure range. Pumping would then transition to a 20-inch cryopump, which can provide up to 10,000 liters/s (on N2) at pressures less than 10-6 Torr.

This 400-square-foot laboratory is used for graduate research and educational activities in fluid dynamics. It houses a low-speed, low-turbulence wind tunnel facility with a one-foot square test section, which is used for experiments on low Reynolds number aerodynamics related to biologically inspired flight, and fluid-structure interaction. These systems are of practical importance in many aero- and hydrodynamic systems, such as micro-air vehicles and flow-induced vibration of flexible cables.
Standard equipment such as vibration shakers, hot-wire anemometry systems, spectral analyzers, digital oscilloscopes, and data acquisition systems are also used in the laboratory.

A bluetooth USB radio provides remote communication with the iRobot® Create programmable robot and the BAM. This wireless mobile sensor network is used for verification of moving source detection schemes as applied to biochemical source detection and containment, and intrusion detection in enclosed spaces. Added to these mobile robots is an autonomous battery-powered helicopter equipped with its own IMU unit and the ability to communicate with the iRobot® mobile sensor network in order to create a heterogeneous sensor network.
