@RamMNK, sir I think you may check this technology out. For a case study. The #DiaphramAirEngine. 

Usually a #cessna150 training airplane consumes 20 litres of fuel per hour that is #Avgas. And in traditional turboprops in countries like the US, have been reducing most of the #lead content in the #aviationfuels i.e., avgas. Now, they are going towards bio-fuel management. Bio-Fuels that have mostly #SynGas. Mixing of #carbonmonoxide and #hydrogen. From #biomass. 

But by using #Air_Diaphram_Engine, we can produce nearly 25000 RPM. The RPM depends upon 2 factors. Air-Pressure, Diameter of the Housing. These pumps use flexible diaphragms to fill and discharge pumping chambers. They are used for transferring fluids like sludges, slurries, and abrasive fluids. The next technology for #modern #airplanes.
