Senior Associate Daniel Wachspress of Continuum Dynamics was recently the guest lecturer at the Korean Society of Aeronautics and Astronautics – 2025 VTOL Aircraft Summer Workshop. CDI has recently partnered with UIT (Unlimited Innovation in Technology) Solutions to provide VTOL aircraft engineering services and technology in South Korea. To kick off this new collaboration, UIT organized a week-long tour of the country where Mr. Wachspress met with companies, research institutes and university professors and students to speak about the capabilities of CDI’s CHARM (Comprehensive Hierarchical Aeromechanics Rotorcraft Model) code. CHARM has been refined over thirty years to accurately model legacy rotorcraft configurations like helicopters and VTOL aircraft, as well as the next generation of multirotor Urban Air Mobility (UAM) and Advanced Air Mobility (AAM) platforms. As part of this tour, UIT arranged for Mr. Wachspress’s lecture as part of a two day summer workshop, focusing on the current status of research and development activities for high speed composite helicopter technology. During the workshop, Mr. Wachspress gave a talk on eVTOL/UAM/AAM aircraft acoustic modeling challenges. CHARM is well validated for rotary wing aeroacoustics modeling, thanks to the work of Mr. Wachspress and Dr. Mrunali Botre of CDI who integrated CHARM with the industry standard PSU-WOPWOP code, which has been widely applied to both legacy helicopters and the rapidly growing UAM and AAM industries. In addition to a seminar on acoustics modelling, Mr. Wachspress provided a tutorial session on the use of CHARM, giving attendees an overview of it’s functionality.
