    Pterosaur "X" plane analysis

    Jim C - I just lost a long detailed post . (!!!!!) I could not respond to you until now due to being banned (there appears to be no indication to others that this has been done and it makes it LOOK like I have either ignored or snubbed you or have no reply to make --none of those are true...

    What is wrong with VTOL? -matters of design philosophy

    Very interesting Cheapie - it looks like a tailsitter and possibly has tilting outer wing panels as well (?) --very much less constraints on an Unmanned VTOL and it makes a lot more sense since they are not doing transport tasks . Tailsitters just bludgeon their way to level flight by...

    What is wrong with VTOL? -matters of design philosophy

    Just as an aside -Jarno quoted the PALV and Maverick as being good but both are NOT VTOL and don't come close to fulfilling this thread's premise (Gyros can take a surprising distance to lift off and then have to maintain forward speed so cannot be vertical -jumpstart gyros need an enormous...

    Distributed Electric Propulsion

    Andy Hahn -just recalled (nice guy, apparently 're assigned' after the PAV program was terminated {"Were' going to Mars !!"} I also suggested that NASA SHOULD take the lead in researching the most promising avenues for getting a workable vehicle and moreover the electronic environment to...

    Distributed Electric Propulsion

    I have no idea if this post will be expunged without warning as were the others I posted earlier (and have Holden's also been erased?) -you DO know that this WAS done on your behalf ,don't you ? ( I was cut off and unable to say anything in my defence on this forum without any warning ) (I have...

    Distributed Electric Propulsion

    Regarding the issue of 'being overly opinionated' 'tired of knowing more than anyone else' and other insulting asides --the general trend being to denigrate any dissention and especially any threat to take the focus off the minutae of your particular embodiment of a generic VTOL scheme . ("move...

    Distributed Electric Propulsion

    Compliments to you too Mark. "bluster"eh ? my dictionary defines this as to 'blow fiercely' amongst other things -- I would have thought that that applied to 'your' proposals with Joby actually. (when I say "your' I reiterate that the idea is as old as aviation almost and approaches the...

    What is wrong with VTOL? -matters of design philosophy

    The Jetsons has been replayed much more recently than it's first TV run (including the movie about a decade or so ago) Among the hundreds of cartoons and Tv series that have come and gone since 1962 no more than a handful are still remembered but if you add 'like the Jetsons' to any piece of...

    What is wrong with VTOL? -matters of design philosophy

    Danger Zone, et al - you have gone to some trouble to be 'comprehensive' so deserve a response more than most. Using your numbering;- 1. VTOL personal flight vehicles en masse ARE 'part of 'their' (govt in EU) 'knowledgeable shemes" as you put it . The EU Foresight program and specifically the...

    Distributed Electric Propulsion

    My earlier posts being deleted disrupts any possibility to conduct a technical argument and the misrepresentation about water landing or something I did not say but could not subsequently defend derailed the very essence of the problem with 'fly in your own slipstream' design schemes of the kind...

    Pterosaur "X" plane analysis

    Jim C - I hope you haven't given up on this thread. Due to circumstances beyond my control.. I could not respond to your last post or (till now) keep my promise to post the evidence of the distinct grooves, pits of whatever they might be called that are visible on the QN skeleton in Melbourne...

    Pterosaur "X" plane analysis

    Hi to all here. I'm brother of Aircar. Uploading some unfortunately less than perfect Pterosaur pics (camera & lighting issues) taken yesterday at Melbourne (AU not Florida) museum as requested by him. Close ups of first neck vertebra of Quetzalcoatlus are meant to illustrate (iirc) anchor...

    What is wrong with VTOL? -matters of design philosophy

    Jay- your post just appeared (after my above) UAVs are an entirely different matter and fall into a totally different part of the scaling spectrum (if VTOL), don't carry human beings or involve 'selling' the concept to the public on some shaky at best premise. It may be too late to recover the...

    What is wrong with VTOL? -matters of design philosophy

    A number of threads and a vast number of ,usually, government funded projects over many years have focussed on VTOL (vertical Take Off and Landing) on the assumption that 'cracking' this problematic area of aircraft design will result in a 'breakthrough' that will enable widespread use of (in...

    Will there be a HBA presence at Oshkosh?

    Our officially designated intrepid reporter needs to be appointed (and given one of those pork pie hats with a large "PRESS" card under the hatband plus one of those official looking cameras with inbuilt flash and telephoto lens.) What would you have in a HBA booth by the way ? Would EAA even...

    "minimum" personal mobility device --ground and airmobile.

    At what point will I have provided ENOUGH answers to satisfy any demand for MORE ? (feeling a bit like Oliver here or maybe the little red hen..) It is the job of a designer to,well,DESIGN --you decide how much of what and see how light or low drag or whatever turns you on you can come up with...

    RTOL (Road Take Off and Landing)

    CTOL has already happened before you fold wings or change hands inside or whatever else --the 'conventional' part involves rolling on and off a hard surface generally extended in the direction of flight with only the aircraft's wheels to guide it until lift off or after touch down . Only the...
