Aviation continues to be an important means of transport for passengers and cargo. However, fuel savings emissions reduction have become increasingly in recent years. As part a PhD thesis, ways reduce consumption by reducing the final reserve were investigated. Improved risk assessment, calculations based on better data decision-making can optimise amount needed without compromising safety leve...

This paper presents an overview of the most relevant fuel cell types and identifies promising options for application in propulsion systems commercial electrified aviation. The general design, operating principles main characteristics polymer electrolyte membrane, alkaline, direct methanol, phosphoric acid, molten carbonate solid oxide cells are described. Evaluation criteria derived from aviat...

A sub-critical microwave discharge is used to achieve a stable ignition and combustion of lean air-fuel mixtures in long tube. The burnt at the presence initiator with quasi-optical beam. resonance way initiation more effective compared traditional plasma-assisted ways stabilization combustion. experimental observations show that air propane mixture tube achieved low limit fuel/air ratio lower ...
