Webb18 feb. 2024 · The helical engine is a hypothetical propulsion system that has been proposed as an alternative to traditional rocket engines. Unlike a conventional rocket, which relies on the reaction mass principle to generate thrust, the helical engine makes use of the properties of spacetime itself to generate propulsion. Webb1 maj 2024 · Rotating detonation engines have attracted attention in recent years due to their extremely rapid, detonative combustion with improved theoretical thermal …

WebbFor engines, the net energy released from combustion is typically represented by the lower heating value (LHV) of the fuel since the water produced by combustion is assumed to remain in the vapor state. Figure 2 shows the LHV of a range of fuels that could be used in an internal combustion engine versus their stoichiometric air fuel ratio. The efficiency of a heat engine relates how much useful work is output for a given amount of heat energy input. From the laws of thermodynamics, after a completed cycle: and therefore where is the net work extracted from the engine in one cycle. (It is negative, in the IUPAC convention, since work is done by the engine.) is the heat energy taken from the high tem… small green computer power supply
