Abstract: A hydrogenfueled twostroke prototype demonstrator based on a 9.9 hp (7.4 kW) production gasoline marine outboard engine is presented, which, while matching the original engine's rated power output on hydrogen, achieves ...

Abstract: Magnetic resonance imaging (MRI) compatible robots can assist physicians with the insertion of biopsy needles and needlelike therapeutic instruments directly into millimetersize tumors, using MR images as feedback. However, ...

Abstract: The inside-out ceramic turbine (ICT), a novel microturbine rotor architecture, uses monolithic ceramic turbine blades held in compression by a rotating structural shroud instead of traditional superalloy turbine blades in ...

Abstract: Increasing turbine inlet temperature (TIT) of recuperated gas turbines would lead to simultaneously high efficiency and power density, making them prime candidates for low-emission aeronautics applications, such as ...

Abstract: This paper presents the design and experimental results of a new micro gas turbine architecture exploiting counterflow within a single supersonic rotor. This new architecture, called the supersonic rimrotor gas turbine ...

Abstract: The inside-out ceramic turbine (ICT) is a promising concept to increase turbine inlet temperatures in microturbines by integrating individual monolithic ceramic. This architecture uses a carbon–polymer composite rim to ...

Abstract: This paper presents the design and experimental characterization of a binary jet valve, specifically developed to control an allpolymer needle manipulator during intramagnetic resonance imaging (MRI) prostate interventions ...

Abstract: Ceramic turbines can reduce fuel consumption by increasing turbine inlet temperatures (TIT). The need for heat-resistant materials like ceramics is particularly acute for small turbomachines for which efficiencies are ...
