Part 1 (25 min)
On entrepreneurship: mixing engineering with business ‐ a personal experience of building &
selling an engineering company.
Dr. Ng will share his experience on being an entrepreneur for over twenty years, while remains a full‐me faculty
at VaTech. This presentaon is targeted towards students (undergrad & grad) who are interested in being an engineering
entrepreneur: the dos & don’ts for being successful in leading a company
Part 2 (20 min)
Analysis of C‐spec sand breakage in a turbine engine parcle ingeson test cell
A turbosha engine test rig has been developed at Virginia Tech’s Advanced Propulsion and Power Laboratory in
cooperaon with the US Navy, Pra&Whitney, and Rolls‐Royce. The engine has been instrumented to allow
measurement of the effects that dust parcles have on the engine (power degradaon) as well as the effects
that the engine has on the parcles (e.g. breakage). The first set of data collected from the engine tests will be
presented, with focuses on changes in the shape and size of C‐Spec (quartz) dust aer passage through the first
five stages of the axial compressor and through the enre engine. Dust samples have been analyzed to determine
parcle size and shape distribuons at the locaons of interest and these have been compared with undigested
material. These analyses suggest that average parcle volume decreased to ∼5% of the original size during
transit through five stages of the axial compressor. The data obtained will assist communies interested in
turbine engine environmental damage in understanding the deterioraon processes and their prevenon. Ul‐
mately, the research will allow for pinpoinng such degradaon effects to a single compressor stage, resulng in
a greater ability to predict engine damage.
Wing Ng is an Alumni Disnguished Professor at VaTech, a pre‐eminent appointment recognizing remarkable
scholarship and service, as well as extraordinary teaching that has influenced the lives of generaons of students.
The honor is given to less than one percent of university faculty. He is a fellow of AIAA & ASME and has
received numerous awards for his research & teaching. While a full‐me faculty, he founded Techsburg in 1998
and managed it unl it was sold in 2020.
