After graduating, Daiju decided to join Dr. Jayant Sirohi’s Aeroelasticity Lab to fulfill his passion for rotorcraft mechanics. He began by performing hover tests with a coaxial counter-rotating rotor (CCR) system and coaxial co-rotating system, comparing the results of each test to quantify how much energy the counter-rotating configuration was able to recover from the wake swirl compared to other rotor configurations. He presented the results at Forum 73 in his paper, “Quantification of Swirl Recovery in a Coaxial Rotor System.”
Daiju is now testing a 6.6 ft (2-m) diameter model-scale coaxial counter-rotating rotor system to understand transient blade passage loads of a coaxial rotor; the findings will be presented at the upcoming 44th European Rotorcraft Forum in Delft, The Netherlands. His mentor Dr. Sirohi is proud of this progress: “Due to his dedication, hard work and attention to detail, Daiju has made significant contributions to his research area; he also spent a great deal of time learning the experimental techniques that he is now an expert in.” Daiju’s ultimate goal is to create an algorithm or experimental methodology to reconstruct the aerodynamic forces acting on helicopter blades from structural response data.
“Receiving the VFF scholarship [in 2017] as a MS student was the first great opportunity for me to be recognized in the rotorcraft community,” Daiju recounted. “The scholarship [in 2018] as a PhD student helped me a lot to apply to summer intern positions, and I was lucky enough to have an intern position at NASA’s Jet Propulsion Lab to work on numerical modeling of energy estimation of rotary VTOL planetary exploration [on Saturn’s moon Titan]. This is truly a dream-come-true moment for me and is one of the biggest impacts on my aerospace career.”
