The project philosophy of the propellers in general will evolve in the future, as in the past, keeping in mind the three fundamental characteristics of aerospace systems: weight, volume, power. Considering the use of the propeller, (military or civil), two other eminently economic factors must be taken into consideration: the lowest possible obsoleteness for military use, the lowest cost of utilization for civil use. Themes of theoretical and experimental research: about the components relative to only the energetic system: subsonic and supersonic combustion processes; traditional and non-traditional combustibles, interaction between the mechanical and combustible system; with combustion in axial fluxes and deviated fluxes; spark ignition; initial combustion and relative phenomena; transitory of the combustion, the combustion rgime; of the fluid-dynamic system components; isolated blades of the compressor and turbine with a small rapport 1/d in subsonic and supercsonic fluxes; elevated load blades in subsonic and supersonic fluxes; annular formation of the compressor and turbine; electronically servo-assisted automation during the transitory phase of any process.
