I agree, Tallak:
I saw “Lilly Dear” (from “The Munsters” old TV show) as flawed from the beginning.
The rows of small, ducted fans seemed too numerous, without sufficient swept area to be efficient. Moving more air, at lower speed is more efficient than moving small amounts of air at high-speed. Today’s jetliners’ high-bypass engines have huge diameters compared to the original cigar-shaped engines, and they travel at slower speeds than the original jetliners, but are way more efficient. Helicopters usually have one large, pitch-controlled rotor, for a reason - efficiency - moving more air at lower speed than a small propeller blowing a small amount of air downward at high speed.
Of course, i was willing to be wrong, and wondered if it was just me missing the big picture or something, but that was my honest take.
The whole idea of electric aircraft powered by heavy, onboard batteries, starts out at a major disadvantage, as a start.
but we’re supposed to iignore all the science and engineering facts learned the hard way over the last century-plus, and pretend some artificial reality along the lines of “Believe us, NOT your lying eyes”.
I love exploring new ideas in engineering, but how much in resources can we put toward falling for multiple, redundant, slow-motion engineering trainwrecks that don’t even pencil out on paper, let alone if properly scrutinized?
