Closer look at the flight dynamics of wings with non-elliptic lift distributions

Prandtl’s alternative solution for wings with minimum induced drag opens another route for improving aircraft performance especially at the conceptual design phase. In this work, the lateral-directional characteristics of such wings are studied for a glider use case from a per-spective that focuses on pro verse yaw and handling qualities. The authors propose an aileron design methodology that ensures roll authority and proverse yaw characteristics. The resultsshow that these conditions cannot be satisfied by a conventional Elliptic configuration, whereaswings with non-elliptic distributions provide several solutions. Non-linear flight dynamic mod-els of the configurations that provided maximum proverse yaw were assessed in an engineering simulator and compared against the baseline Elliptic case. Proverse yaw was observed in thesimulation data and pilot feedback indicated improved handling qualities in the non-elliptic cases. However, the inherent directional instability combined with other lateral-directional coupling effects masked the observations from the pilot’s perspective

The Holistic Impacts of Intergenerational Senior Wellness Programs for Recreational Therapy Professionals In Training and Residents in Long Term Care Settings

Intergenerational programs serve the older adult population alongside young children, youth, and/or young adults and their design is intended to be mutually beneficial. In this session, we will discuss the community engaged learning project with Old Dominion University Recreational Therapy students and their residential care partnership with Beth Sholom Village. We will further present the holistic benefits experienced by both populations and identify changes to perception towards aging. Additionally, we will emphasize the benefits of this program to future Recreational Therapy professionals and highlight this program as a model for improving the field of Therapeutic Recreation and the quality of life of the individuals which our interventions serve
