Greening civil aviation is key to our global future. It is imperative to succeed without the vast economic and social damage that would follow constraining aircraft demand and operations.  So radical aircraft propulsion technologies must be developed urgently.  Most likely to succeed in this grand challenge (promising full decarbonisation) are hydrogen (H2) and electrification.  H2 is an inevitable solution for a fully sustainable aviation future, via hybrid/fuel cell technologies for short to medium range and H2 combustion in gas turbines for longer missions. This presentation will provide an overview of the ongoing EU H2020 “ENABLing CryogEnic Hydrogen-Based CO2-free Air Transport” (ENABLEH2) project being coordinated by Cranfield University. The case for LH2 for civil aviation will be discussed followed by the strategic importance and overall scope of ENABLEH2. A summary of the key achievements to date will presented for the ENABLEH2 research on:

  • Ultra-low NOx hydrogen micromix combustion
  • Fuel system heat management – to exploit the formidable heat sink potential of LH2
  • Safety
  • LH2 Aircraft “Technology Evaluation”        

The presentation will conclude with an overview of twelve key research technology strands (identified as part of a preliminary roadmapping exercise in ENABLEH2) that are necessary for accelerating the entry-into-service of LH2 aircraft to realise the environmental benefits as soon as possible. 

 

Biography

In 2004, Dr Sethi received an MSc Thermal Power degree from Cranfield University where he was also awarded the "British Aerospace Companies" Prize. Dr Sethi completed his PhD in the Department of Power and Propulsion at Cranfield University in 2008. Upon completion of his PhD, Dr Sethi joined the School of Engineering as a Research Fellow and was promoted to Lecturer in 2012.

In 2019 he became Deputy Director of Research, School of Aerospace, Transport & Manufacturing  and in 2020 he also became Associate Professor in Gas Turbine Combustion and Environmental Impact.

He is currently Overall Project Coordinator and CU Principal Investigator for the ~€4M EU H2020 ““ENABLing CryogEnic Hydrogen-Based CO2-free Air Transport” ENABLEH2 project (20+ key EU civil aviation stakeholders – partners and Industry advisory board members)

A seaplane gives the ultimate freedom of flight with theoretically endless take-off and alighting possibilities

along the coast, on lakes and rivers – and not to forget on the open seas. The design of seaplanes is based on

the knowledge of aircraft design and speedboat design. The craft must meet buoyancy and lift requirements.

Hydrostatic and -dynamic stability has to be matched with the longitudinal and lateral static and dynamic

stability in the air. The structure has to withstand water and air loads. Crucial are hydrodynamic resistance at

take-off as well as the lift-to-drag ratio in flight and particularly the water loads in defined sea states.

Sea plane design has a glorious past, but much of the knowledge is buried in dusty archives. It is even worse if

knowledge is lost forever and needs to be reinvented.
