Re: A 9 passenger electrical plane available

First Model S had the range of over 300km while Renault Zoe had a range of less than 150km and performance gets worse from there. Today , Model S gets at least 600km range while Zoe gets little over 300km. Model S is more than twice the car of Zoe and Leaf. Model S is a viable future model while Zo...

Re: What is the minimum battery power density needed for a 2000nm range?

Re: What is the minimum battery power density needed for a 2000nm range?

One of the big issues is that batteries don't lose weight as they discharge. On the other hand as you burn fuel that weight disappears. This has a massive effect on range. Also, an A350-1000 might carry a maximum of 124 tonnes of fuel, but not even the longest flights use that much. If nothing else...

Re: RR begins building worlds largest jet engine

Unlikely. Because of the much better fuel economy a stretched A380neo would never have needed the MTOW originally envisioned.

The engine at this particular size was never intended for an A380neo application. The A380 does not need ~85k+ Lbf of thrust for each engine.
