On the 4th of February, grad students and faculty members from the Department of Aerospace Engineering gathered in the Materials Testing Lab of the Lehman Engineering and Technology Center to conduct a structural compression experiment on a composite panel which employs a new structural design concept developed by Boeing and NASA to meet the needs of future aerospace vehicles.
The university team was joined by Field Applications Engineer, Naman Garg of Luna Innovations Inc. who provided optical-fiber sensing measurements to complement the strain gage setup instrumented by the students. The panel fabricated using the Pull-Extruded Rod Stitched Efficient Unitized Structure (PRSEUS) concept has been under development by Boeing and NASA to enable the implementation of novel aerodynamic solutions such as the hybrid wing-body (HWB) concept for the future of large transport category aircraft.
However, researchers at Embry-Riddle working with the Boeing Research and Technology Group have been exploring the potential of PRSEUS as applied to current generation designs found in the general aviation industry. With Gulfstream Aerospace now interested in the effort as well, Dr. Ali Tamijani and his student, Samaksh Behl are developing computational models to investigate the benefits of PRSEUS on the wing and fuselage structure of the recently certified G650 business jet. Yesterday’s experiment led by Dr. Daewon Kim has offered preliminary results which suggest good agreement with computational predications. A lot of work still remains though, and the next couple of weeks will see students and faculty analyzing the gathered data.
