June 10, 2020, ©. Leeham News: France presented a 15 billion Euro support plan for the French aeronautical industry yesterday, to help the industry overcome the effects of the COVID-19 pandemic.
The plan has three focus areas:
May 1, 2020, ©. Leeham News: We now wrap the series about technologies that can help reduce air transport’s environmental footprint.
I wrote in the first article, December 13: We have lost our way in our search for a lower carbon footprint air transport system by heading down the electric lane. I will argue why it’s not the best route as it’s not the route that leads to tangible results any time soon, despite huge investments.
In 19 Corners to date, we discussed why. It’s time to summarize what we learned.
April 24, 2020, ©. Leeham News: Before we wrap the series about technologies that can help us reduce the environmental footprint of air transport, we describe what the ICAO emissions scheme CORSIA is, its goals, and comment on its importance.
April 17, 2020, ©. Leeham News: We continue the summary of the series why e in ePlane should be more about environment focus than electric aircraft.
Last week we summarized the high hanging fruit technologies pursued presently, now we continue with the low hanging fruit.
April 10, 2020, ©. Leeham News: We have since December 13, discussed why e in ePlane should not stand for electric and covered a lot of areas explaining why electric aircraft or hybrids are not the best way to environmentally friendly air transport.
We now recap what we learned and then wrap the series.
April 3, 2020, ©. Leeham News: In this week’s Corner, we go deeper into bio-based carbon-neutral fuels. We described the two variants of bio-based and synthetic alternative fuels last week and gave an overview of the pros and cons of synthetic fuel.
Now we dig deeper into bio-based airliner jet fuels, an already existing carbon-neutral fuel type.
March 27, 2020, ©. Leeham News: In this week’s Corner, we analyze the use of carbon-neutral fuels for airliner use.
Almost all variants of carbon-neutral fuels have the “drop-in” advantage, they can replace our regular jet fuel in a mixed capacity or entirely with none or minimal changes to our present aircraft and their engines.
It’s a big subject, and I will use the next Corners to explain the key alternatives, their production process, and what benefits and problems they bring.
March 20, 2020, ©. Leeham News: In this week’s Corner, we continue our analysis of what it means for a regional airliner to go from Turbofan propulsion to Hybrid Electric propulsion. Last week, we looked at a Serial Hybrid. Now we analyze a Hybrid where the electric power applies in parallel with the gas turbine power.
March 13, 2020, ©. Leeham News: In this week’s Corner, we address an often forgotten aspect of Electric and Electric-Hybrid aircraft design.
The battery as an energy source, as the only or assisting source, has the same weight during the whole flight. A fuel (alternate, fossil, or hydrogen) consumes during the flight. You gradually fly a lighter aircraft. Let’s see how this affects the aircraft’s efficiency.
March 6, 2020, ©. Leeham News: We use this week’s Corner to discuss the safety hazards a change to an Electric or Hybrid-Electric airliner introduces.
The trigger is two battery fires in six weeks for the electric aircraft prototypes which are now flooding the market.
