    Russian UFO (not)

    =at 15:30 =MUSH regime ! (vertical descent, Vhor.=0 ) -thanks low span=good for FLYING car !

    Ducted Fan Pseudo-Jets

    -I agree,BUT iff the "thing" seems VERY GOOD ? BTW=it exist russian words= "сила есть,ума не надо!" -in auer case=iff we have big thrust, we can ignore the drag ! (in contrary,for economic "electric" fly we need LOW drag...)

    =? (another word...?) PS= "A single speed combustion engine drives the rear fuselage fan at very high efficiency, due to the Goldschmied fuselage propulsor. "

    =look at comment (Goldschmied aerodynamic)...

    Ducted Fan Pseudo-Jets

    =very strong shirm for distorsied blades (iff bird streik !) -I think, the best solution is many radial inlets (big surface) +laminar flow extension (fuselage drag reduction)...

    =NOTCHED duct, =STEPPED duct... BTW="to protect people from the prop " =kevlar composite ring inside notch/step...?

    Source for 2024 tubing?

    =not similar E-modul...?

    The concept of a flying car will eventually succeed

    -any positive results in DUCTED fan experiments ? (Josef cooperation ...)

    Ducted Fan Pseudo-Jets

    =iff involve EJECTOR nacell,ruway can be shorter... =iff CRDiff. syxstem=+30 % thrust !

    Celera 500l Progress

    =iff HCCI ? (detonation ignition...) f,e. "gun engine". (95 % eficiency !)
  14. H

    What do you think about "e-soaring"?

    +good knolage... (probably pilot drived wheel =better acceleration) -bischen better ? or (am besten, SIMPLEST !)
