Exciting Future Research
Opportunities
• With the present capabilities, our group at OSU has the
necessary infrastructure, competencies to carry out
exciting and important research of interest to NASA,
AFRL, OEMs, Industries and Small businesses
• Look forward to research agreements on topics of
mutual interest
• Ready to form and lead a team of researchers at OSU to
carry out multi/inter disciplinary research projects
• We assure you high quality research output to move
DECWG’ s vision forward
• Can help DECWG to create ‘Repository’ of open
literature on engine modeling, control and simulation.
