CHRISTIAN GUIN is an academic who published a paper in 2016 entitled Challenges in Combustion for Aerospace Propulsion. CHRISTIAN GUIN published this work as part of a team: Dupoirieux, Francis. Here is a description of this work: Given that combustion involves fuels in which chemical energy is very dense and is able to deliver a very high power/volume ratio, this mode of energy conversion, despite its negative aspects, will remain unavoidable for aerospace propulsion in the long term. One of its negative aspects relates to the conversion into kinetic energy of the heat released by combustion, which yields a thermodynamical efficiency that is necessarily much less than one. The improvement of this efficiency is achieved by increasing the pressure and temperature, which leads to increasingly tougher operating conditions in combustion chambers. Other issues are combustion instabilities, which compromise safety, load comfort and engine lifespan, as well as CO2 and miscellaneous pollutant emissions, combustion noise and ignition or re-ignition during flight. In order to tackle all of these points it is necessary to fully underst.
