ABSTRACT
Biofuels have relatively high thermal conversion efficiencies. Multiple airlines are conducting test flights along commercial routes to evaluate the performance of biofuel blends under regular operational conditions. The nature of a biofuel makes it an attractive choice to power engines. As well as being nontoxic and biodegradable, biodiesels have a most convenient lubrication property. Third generation biofuels may be obtained from easily farmed algae, which can even be genetically manipulated to improve its properties for combustion purposes. Concerns about the cost effectiveness of a viable commercial solution, as well as the sustainability of the production must be addressed. Among the various design challenges encountered during the development of a jet engine at the UNAQ, the following two have required special attention: the hydrodynamic features affecting the fuel injection system and the geometry of the combustion chamber. Some technologies are attaining sufficient maturity to help overcome the injection problems in an efficient manner.
