Embodiment Construction

[0043] The invention described herein relates to generating propulsion for an aircraft. A particular engine system for an aircraft includes multiple engines.

[0044] figure 1 A simplified schematic diagram of a prior art conventional propulsion plant 10 and a schematic diagram of a prior art hybrid electric boundary layer suction engine 20 are shown. A prior art conventional propulsion plant 10 has a first combustion engine 12 and a second combustion engine 14 . Both combustion engines 12 , 14 are fed by a source of combustible fuel contained within a fuel tank 16 . The engines 12, 14 and associated propellers combine to ignite a fuel and air mixture and inject the mixture to provide propulsion for the aircraft. The source of combustible fuel can be kerosene, biofuel or natural gas etc.

[0045] A prior art hybrid electric boundary layer inhalation engine 20 has a first combustion engine 22 and a second combustion engine 24 powered by fuel tanks housed in respective fuel ...

Abstract

The present invention relates to a multi-source aircraft propulsion arrangement comprising a cryogenic propulsion source and a combustion propulsion source wherein the cryogenic propulsion source and the combustion propulsion source may be selectively and independently operated to generate propulsive force for an aircraft.

Description

technical field [0001] The present invention relates to aircraft propulsion systems, and in particular aircraft propulsion, which are responsible for large quantities of harmful gaseous emissions. Background technique [0002] According to most estimates, air traffic is set to double every fifteen years, which would substantially increase the operation of land-based propulsion systems and subsequently airborne propulsion systems, thereby increasing the generation of associated emissions. Emissions are known to be harmful, whether generated on the ground or at high altitudes. [0003] The use of alternative fuels has been identified as a possible avenue to explore in order to meet the emission reduction targets set by the International Air Transport Association. Alternative fuels include biofuels, synthetic kerosene, compressed natural gas. Additionally, the ACARE Roadmap to 2050 identifies needs and sets targets for significant reductions in a range of emissions. It is we...
