  • Aeroelastic Gust-Airfoil Interaction Numerical Studies

    PI Vladimir Golubev

    The project conducted in collaboration with WPAFB and Eglin AFB AFRL scientists over the past 8 years employs DOD HPC and ERAU computer facilities to conduct high-fidelity, low-Reynolds, aeroelastic gust-airfoil interaction studies to model unsteady responses and their control for small UAVs operating, e.g., in highly unsteady urban canyons.

    The focus is on modeling airfoil interactions with canonical upstream flow configurations including time-harmonic and sharp-edge gusts, vortices and synthetic turbulence with prescribed characteristics tailored to a specified unsteady flight-path environment. Note that this and other listed projects that include noise predictions and noise/flow control components are partially supported by Florida Center for Advanced Aero Propulsion (FCAAP) in these efforts

  • Self-Sustained Flow-Acoustic Interactions in Airfoil Transitional Boundary Layers

    PI Vladimir Golubev

    CO-I Reda Mankbadi

    This work carries out collaborative theoretical, experimental and numerical investigations of flow-acoustic resonant interactions in transitional airfoils which are responsible for sudden appearance of prominent acoustic tones and unsteady aerodynamic fluctuations in low-Reynolds-number airfoils.

    The experimental part of the efforts is implemented in France at anechoic wind tunnel facility of Ecole Centrale de Lyon, while numerical and theoretical studies are conducted at Embry-Riddle using DOD HPC facilities. The project involves several PhD and MSAE students both in U.S. and France.

  • Wake Vortex Safety Analysis in the Context of UAS Integration in the NAS

    PI Vladimir Golubev

    ​This project is a collaboration with several research organizations under the supervision of FAA. The focus  of the current research efforts is on developing and employing variable-fidelity prediction approaches to examine safety implications of the future integration of variable-size UAS systems in the National Aerospace System (UAS). 



    In particular, variable-fidelity prediction methods to accurately resolve all aspects of aircraft wake generation, evolution, interaction and control are developed. The results of this research will be incorporated in the FAA Integrated Safety Assessment Model developed for analysis of risk implications of UAS operations in the terminal zones and beyond.

  • Integrating Engineering and Aviation Standards in Higher Education Curriculum

    PI Leila Halawi

    CO-I Marwa El-Sayed

    CO-I Mark Miller

    CO-I Sophia White

    This project aims to develop a transferable plan for integrating industry standards into engineering and aeronautics programs, with a short-term goal of refining learning modules. It has the potential to serve as a model for other STEM institutions and improve learning outcomes at both undergraduate and graduate levels.

    This proposal aims to accomplish three broad yet related objectives: (1) Create two customizable educational modules for three targeted courses: a) Two undergraduate in engineering; b) One graduate in aeronautics; (2) Evaluate the student learning outcomes through different stakeholders including university advisory/industry board, and subject matter experts across our campuses; and (3) Develop and offer a model curriculum suitable for other colleges and universities to use in teaching and integration of standards across the curriculum, leading to certifications.

  • Multiscale Computational and Experimental Framework to Elucidate the Biomechanics of Infant Growth

    PI Victor Huayamave

    There is currently a lack of biomechanical quantification of growth and development because: (1) there is no generic musculoskeletal infant model, and (2) the lack of infant data in the literature.

    An infant’s spontaneous movements generate forces that are constantly acting on the joints and can affect the morphology and development of soft bone. Using experimental motion capture data, statistical shape modeling, and multi-scale musculoskeletal mechanobiological models, we will be able to predict the complex adaptation of the joint to biomechanical factors, thus providing a biomechanical basis for improved prevention and treatment of developmental disorders. This project pioneers the development of solutions that improve intervention and outcomes of conditions such as scoliosis, spina bifida, clubfoot and developmental dysplasia of the hip. The model provides a non-invasive three-dimensional approach to study the dynamics of human movements using biomechanical parameters that are difficult or impossible to examine using physical experiments alone. Our proposed research will advance pediatric movement science and will uncover the underlying mechanisms involved in the maturation of the hip joint during early development. Results from the proposed research will: (1) Provide experimental data and computational models that can serve as the basis for developing innovative solutions for infant developmental disorders; (2) Develop innovative tools to aid clinicians, pediatricians and physical therapists when managing joint disorders; (3) Identify factors that drive and regulate growth early in life that may have long-term benefits for prevention of early arthritis. Each of these contributions is significant given that joint disorders such as developmental dysplasia of the hip underlie around 29% of all primary hip replacements in adults.

  • Integrated Structural Health Sensors for Inflatable Space Habitats

    PI Dae Won Kim

    PI Sirish Namilae

    Under this research project we will develop an innovative structural health monitoring system for inflatable space habitat structures by integrating nanocomposite piezoresistive sensors 

    Inflatable structures for space habitats are highly prone to damage caused by micrometeoroid and orbital debris impacts. Although the structures are effectively shielded against these impacts through multiple layers of impact resistant materials, there is a necessity for a health monitoring system to monitor the structural integrity and damage state within the structures. Assessment of damage is critical for the safety of personnel in the habitat, as well as predicting the repair needs and the remaining useful life of the habitat. We are developing a unique impact detection and health monitoring system based on hybrid nanocomposite sensors composed of carbon nanotube sheet and coarse graphene platelets. An array of these sensors sandwiched between soft good layers in a space habitat can act as a damage detection layer for inflatable structures. We will further develop algorithms to determine the event of impact, its severity, and location on the sensing layer for active health monitoring.  Our sensor system will be tested in the hypervelocity impact testing facility at UDRI in future.
