BOOMLAB - Sharing the Science of Boomerangs - Boomarology
Brent W. Pomeroy * and Daniel V. Uhlig ** working at the University of Illinois at Urbana-Champaign, Department of Aerospace Engineering, did a project in about 2014 tracking a small indoor boomerang (roomerang) with Vicon cameras to accurately track its path and orientation. They got great results and did detailed analysis of the flights. This is one of the best practical insights into the flight path and behaviour of a boomerang.
* In the paper Brent describes himself as "Graduate Student, Department of Aerospace Engineering, AIAA Student Member, Fledgling Boomerang Authority."
** Daniel is described as "Graduate Student, Department of Aerospace Engineering, AIAA Student Member, Aspiring Boomerang Buff."
Brent Pomeroy - Boomarologist
Experimental Equipment was a roomerang and some Vicon cameras. They tried to make a boomerang launcher but like others before them they found only humans can throw a boomerang
The results include an excellent graph of how the boomerang lays over - what they call 'incline angles'
