Preliminary Design of a Recuperator for a Gas Turbine Range Extender Application

Range extended electric vehicles (REEV) are being considered as a possible solution for the electrification of passenger vehicles. The application of a recuperated gas turbine (GT) for REEVs shows potential in terms of power-to-weight ratio, emissions and cost. The recuperator plays a major role in achieving target efficiency, while being a main...

Electrically Assisted Propulsion & Power Systems for Short-Range Missions: Electrification of a Conventional Airbus A320neo

Over the last 50 years, the global airline industry has seen resilient growth in the demand for passenger travel; this trend is expected to continue in the coming decades. With kerosene being the predominant source used as jet fuel, this increase in air traffic is expected to result in the depletion of non-renewable fossil fuels and undesired...

Development Of A Preliminary Lifing Analysis Tool For The F135-PW-100 Engine

In the near future the Royal Netherlands Air Force will replace their fleet of F-16’s with the F-35. In the past the NLR has aided the Air Force with life cycle and deterioration analysis work on the F100-PW-220 engine, which powers the F-16. Understanding the physical system of the engine allows for on-condition maintenance. The same is...

System Study Towards the Integration of Indirect Biomass Gasification, Methanol and Power Production

The transition from a fossil based economy to a greener, bio-based economy remains challenged by the gap in technological maturity between bio-based processes and conventional fossil energy. Decreasing the price difference between fossil fuels and bio-fuels remains a major constraint. With 98% of the transportation sector now depending on fossil...

Parametric Emission Prediction Model in Gas Turbines with Exhaust Gas Recirculation

One of the challenges in gas turbines is in the reduction of NOx and CO emissions due to simultaneous<br/>dependence on stringent emission norms and subsequent demand for change in operating conditions. To cater the volatile demand of power supply, most of the gas turbines have to be flexible to changing loads. Closer the load is to full load,...
