RISOptimize Energy Efficiency of Quadrotors Via Arm Rotation
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Quadrotors have been used in many areas such as cargo transportation, agriculture, and search and rescue. The low energy density of power sources and the low energy efficiency of quadrotors have prevented quadrotors from ...
Study on a Vapor Feed Air Breathing Direct Methanol Fuel Cell Assisted by a Catalytic Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Feeding vaporized methanol to the direct methanol fuel cell (DMFC) helps reduce the effects of methanol crossover (MCO) and facilitates the use of highconcentration or neat methanol so as to enhance the energy density of ...
Structural Characterization of a Novel Gas Foil Bearing With Nested Compression Springs: Analytical Modeling and Experimental Measurement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel nested compression spring gas foil bearing (NSFB), which used a series of nested compression springs as compliant supporting structure, was proposed and designed. NSFBs can be easily manufactured and are able to ...
