A propulsion and electric power generation system includes a gas turbine propulsion engine, an electrical generator, an aircraft power distribution system, a plurality of auxiliary fans, and a controller. The gas turbine propulsion engine includes at least a low-pressure turbine coupled to a fan via a low-pressure spool, and the low-pressure turbine is configured to generate mechanical power. The electrical generator is directly connected to the low-pressure spool and generates a total amount of electrical power (Pe). The aircraft power distribution system receives a first fraction (Pa) of the total amount of electrical power. The auxiliary fans receive a second fraction (Pf) of the total amount of electrical power. The controller is configured to control a ratio of Pf to Pa (Pf/Pa) such that the ratio spans a range from less than 0.6 to at least 0.9.

An internal combustion engine has a brace and/or an engine block mounting system coupled to the engine block and arranged to reinforce and minimize deformation of the engine block. The reinforcement and reduced deformation of the engine block allows a lubrication system to provide reduced oil pressure to minimized clearances between mating internal engine components in relative motion. Meanwhile, permanent magnets are disposed in the piston, the connecting rods, and/or the crankshaft. Electromagnets are disposed in the engine block, the cylinder head, the brace, and/or the oil pan. A control system selectively provides an electrical current to the electromagnets to produce a desired magnetic field and affect the motion of the crankshaft. In at least one embodiment, the brace has a circular structure that surrounds part of the crankshaft and supports the plurality of electromagnets. In other embodiments, the brace is coupled to the main caps that support the crankshaft.

A vehicle has an internal combustion engine, an accessory, and a system having first and second belts extending between a drive assembly rotatably connected to a crankshaft of the engine and a driven assembly rotatably connected to a driveshaft of the accessory. One of the drive and driven assemblies comprises a mechanism with a shaft supporting first and second pulleys, with the first and second pulleys associated with the first and second belts, respectively. The first pulley is selectively engaged with the shaft in response to an engine speed being below a threshold value, and the second pulley is selectively engaged with the shaft in response to the engine speed being above the threshold value.

Disclosed is a rotary engine, comprising a stator and a rotor rotatably connected thereto. A stator holder with an annular recessed variable track guide groove is on each end of the stator. A sidewall, close to the rotor, of the stator is provided with an arc-shaped combustible gas groove, a combustible gas inlet, a ring-shape groove, a combustion chamber, a decompression device and an exhaust gas outlet. A compression-resistant element is provided in the ring-shape groove. The rotor is provided with a combustible gas piston chamber having a combustible gas piston, a slider slot having slider, and gas exchange channels. The sliders on the same generating line on the rotor and the combustible gas piston are connected fixedly to the same sliding rod in a sliding rod groove, and the two ends of the sliding rod extend into the annular recessed variable track guide groove of the corresponding stator holder.

Provided are systems and methods for transport vehicles using recyclable metallic fuels. The method includes capturing fuel products, including a metal oxide and unburnt fuel from the combustion of a metallic fuel, storing the unburnt metallic fuel and the fuel products, and recycling the metal oxide to recreate the metallic fuel and/or byproducts. Heat generated by the combustion and/or sintering of the metallic fuel may be transferred to a working fluid to drive the production of electricity and/or to provide propulsion in land, air and water vehicles and spacecraft. Furthermore, the thermal energy harvesting system may be used to generate electricity. The system includes a thermal (heat) engine having an induction heating assembly for heating the metallic fuel. Processes for complete combustion of the metallic fuel and recycling the metallic fuel in a sintering loop are described.
