A Novel Multi-speed Dedicated Hybrid Transmission with Superior Fuel Economy and Acceleration Performance

As road transportation contributes 17% of global CO₂ emissions, the shift toward electrified powertrains has accelerated. While electric vehicles still face challenges like limited infrastructure, range anxiety, and battery-related concerns, hybrid electric vehicles (HEVs) and plug-in HEVs, which offer a balance between lower emissions, range, and cost,

Dual Adaptive Propeller System

This study presents a groundbreaking Dual Adaptive Propeller System designed to overcome the inherent limitations of current propulsion technologies in UAM and VTOL applications through innovative thrust modulation and aerodynamic control mechanisms.

As urban air mobility (UAM) and vertical take-off and landing (VTOL) systems evolve, propulsion technologies must adapt to the demands of compact designs, agile maneuverability,

Ferrocement Adaptive Optic Heliostat

On paper, power towers look great. So why are they shutting down?

One reason is current solar power tower heliostat fields are limited to 1500°F maximum because of flat heliostats. This new adaptive optic heliostat innovation creates higher temperatures 2500°F, which now allows for greater industrial applications, such as using the sun to manufacture cement, steel, fuel,

The Piston Pneumatic Motor With High Environmental and Techno-economic Indicators

The proposed development will allow to increase the efficiency of using energy of compressed air in piston motors for generating energy to move a vehicle or a stationary engine (with daily fluctuations in electricity consumption). The considered technical solution will contribute to improving the environmental and techno-economic indicators of piston motors when using compressed air in them.

Radial to Radial Pump

I'm not sure how to classify this unit, however it does pump. The impeller is completely symmetrical in all respects. This pump also works in both directions automatically. I have 3D-printed working models. Could this be a new pump design as I know of three types: axial, semi axial, centrifugal and gear style. Radial to radial?
