Predicting constraint point loads for a vehicle towed along a fixed path
(2020-12)
Towing a vehicle along a fixed path is useful in automation processes. Understanding the forces involved while towing a vehicle is critical for the design of the towing system. For aircraft in particular, careful measures ...
Viscoelastic Poisson's ratio of webs
(2020-12)
During web handling operations, the web moves along a processing line, supported by rollers, and is subject to numerous successive processes, for example several printing operations with different colors. Registration ...
Exploring mechanical assonance for impact energy harvesting using acoustic metamaterials
(2020-12)
Acoustic metamaterials are engineered to possess unique dynamic properties that are not commonly found in nature. It has been demonstrated that customizing the characteristics of their local features can help optimize their ...
Design, analysis, and integration of a turboelectric propulsion and power system for unmanned aircraft
(2020-05)
Electrically powered small unmanned aerial systems face limited range and endurance due to the inherently low energy density of current level of technology batteries. Hybrid gas-electric systems are under development and ...
Experimental dynamic characterization of meta-configured structures for aerospace applications
(2020-07)
Drawing inspiration from acoustic metamaterials, meta-configuration as a means to improve coactive mechanisms between sub-structures to enhance overall structural performance is investigated with a primary focus on aerospace ...
Computational and experimental investigation of Brazilian Free-Tailed bat ear tubercles on an airfoil leading edge
(2020-05)
Preliminary experimental data has indicated that the tubercles on Brazilian Free-Tailed bat ears, when applied to an airfoil leading edge, reduce drag and delay aerodynamic stall. This study's objective was to investigate ...
Control and commissioning of a hot-gas bypass compressor load stand for testing light-commercial compressors using low-GWP refrigerants
(2020-07)
As a result of changing efficiency standards for HVAC&R equipment, hydrofluorocarbon refrigerants such as R134a and R410A are in the process of being phased out because of their high Global Warming Potential (GWP). Many ...
Design and development of a water observatory: An autonomous environmental sampling system for in-situ sensing of lakes and rivers
(2020-12)
This project focuses on the design, development, and implementation of an autonomous system, or unmanned surface vessel (USV), known as MANUEL (Mobile Autonomously Navigable USV for Evaluation of Lakes). MANUEL is an ...
Tribological and cavitation erosion behavior of metallic glass reinforced aluminum matrix composites processed using spark plasma sintering
(2020-07)
Metallic glasses are emerging as a potential reinforcement for lightweight metal matrix composites. With their high strength, high elastic strain limit, and metallic nature, metallic glasses have better prospects of improving ...
