Safety Systems, Culture, and Passengers’ Willingness to Fly in Autonomous Air Taxis

  • PI Kenneth Ward

    CO-I Scott Winter

  • As city populations grow, the transportation industry plans to alleviate traffic congestion by introducing the urban air mobility (UAM) concept, in which small passenger and cargo aircraft augment metropolitan transportation networks. A key component of UAM is that of air taxis, which are on-demand air services for individuals and small groups. In addition, UAM companies are designing the aircraft to operate fully autonomously: The intent is for the vehicles to arrive and transport people from point to point without input from human pilots.

Science and engineering proof of concept study for the Next generation Space Weather Prediction mission and space weather model development

  • PI Heidi Nykyri

  • Project analyzes astrodynamics (transfer trajectories) and spacecraft constellation stability about all Lagrange points for Mercury, Venus, Earth, Mars system for the "next generation" space weather prediction mission, and develops a solar wind model which will use data from this mission
Seaplane design analysis: Focus on structure factor optimization

  • PI Alberto Mello

    CO-I Soham Bahulekar

    CO-I Sergio Butkewitshch

    CO-I Wesley Queiroz

  • In this work, a design optimization is being investigated considering possible hydrodynamic and structural advantages aiming to reduce the structure weight factor, with a trade-off between fluid dynamics and structural aspects.
Searching For Subdwarf B Long Orbital Period Binary Systems And Single Stars Using The Light Time Delay Method

  • PI Tomomi Otani

  • Our group, which includes both graduate and undergraduate students, studies the formation of subdwarf B (sdB) stars by investigating their binarity through stellar pulsations. We use photometry data from the TESS space telescope to measure precise pulsation frequencies, distinguish between binary and single-star systems, and determine orbital solutions for candidate binaries. This research is supported by NASA funding.
Secret Sharing Over a Gaussian Broadcast Channel: Optimal Coding Scheme Design and Deep Learning Approach at Short Blocklength

  • PI Rumia Sultana

  • ​We consider a secret sharing model where a dealer shares a secret with several participants through a Gaussian broadcast channel such that predefined subsets of participants can reconstruct the secret and all other subsets of participants cannot learn any information about the secret.
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.
Self-sustaining Wind Energy Extraction Technique (SWEET) Using Multi-Level Control Design Methods
Shielded UAS Operations Detect and Avoid

  • PI Hever Moncayo

  • ​This effort is intended to identify risks and recommend solutions to the FAA that enable shielded UAS operations
Simulation Based Inquiry Oriented Linear Algebra

  • CO-I Ashish Amresh

  • Games that teach introductory concepts in linear algebra such as vectors, span and dependence are created to be used by instructors in an undergraduate class.
Small UAS (sUAS) Mid-Air Collision (MAC) Likelihood

  • PI Ryan Wallace

    CO-I Dothang Truong

    CO-I Scott Winter

    CO-I David Cross

  • This research focuses on sUAS MAC likelihood analysis with general aviation (GA) and commercial aircraft. Because severity research varies based on where a collision occurred on a manned aircraft, this likelihood research will not only look at the probability of a MAC, but also the likelihood of colliding with different parts of a manned aircraft.
Software Infrastructure For Analysis of Infection Propagation Through Air Travel

  • PI Sirish Namilae

  • This NSF funded  project seeks to develop a novel software that will provide a variety of pedestrian dynamics models, infection spread models, as well as data so that scientists can analyze the effect of different mechanisms on the spread of directly transmitted diseases in crowded areas. The initial focus of this project is on air travel. However, the software can be extended to a broader scope of applications in movement analysis and epidemiology, such as in theme parks and sports venues. Development of the proposed software will involve several innovations. It will include a novel phylogeography model that links fine-scale human movement data with virus genetic information to more accurately model geographic diffusion of viruses. New models for pedestrian movement will enable modeling of complex human movement patterns. A recommendation system for the choice of pedestrian dynamics models and a domain specific language for the input of policies and human behaviors will enhance usability by researchers in diverse fields. Community building initiatives will catalyze inter-disciplinary research to ensures the long-term sustainability of the project through a critical mass of contributors and users.

Space Operations in the NAS: Analysis of Impacts to the Aviation Industry
  • The basic goal of the research is to understand impacts to aviation stakeholders of the National Airspace System (NAS) due to space launch activities.  The focus of the research is to study impacts to general aviation (GA), particularly with respect to airports and airport users, near and around Cape Canaveral, FL. Further, several avenues will be assessed to determine what aspects of GA are impacted, where, when, how, and why. Data will be collected and analyzed in alternate methods other than the originally-proposed simulation and modeling. As an aside, per FAA input and following review of extant literature, impacts to GA have not been adequately researched. Until recently, the industry and the FAA have largely focused on impacts to airlines (Tinoco, Eudy, Cannon 2020). As a result, we believe this effort will lead to interesting outcomes and fill a much-needed gap in the literature.
