    Could the Inflatable Aircraft Concept Be Updated/Modernized?

    I even found old pics of this British military thing

    Could the Inflatable Aircraft Concept Be Updated/Modernized?

    Regarding Tensairity, what I've noticed from perusing various examples of it, is that it seems to mainly be used on static structures - particularly ones which are spanning gaps between static anchored objects. For instance, making a bridge that spans between the anchorpoints on each side of a...

    Could the Inflatable Aircraft Concept Be Updated/Modernized?

    The key question is - where are the most important places to put these rigid structural parts, which are going to add weight and will also require mechanical joints/hinges/telescoping for portability/collapsibility on the ground. Could it be possible to first create a collapsible lightweight...

    Could the Inflatable Aircraft Concept Be Updated/Modernized?

    Here's a placeholder website for Aereon Corporation (the official one apparently went offline): https://aereoncorp.com/.pages/aereon26.html And here is their description of the Aereon 26 (emphasis mine):

    Could the Inflatable Aircraft Concept Be Updated/Modernized?

    I found this example of some kind of attempt to use Tensairity for something that flies:

    Which types of shapes does Tensairity favor or work best with? Also, has Tensairity ever been used in an aircraft?

    Could the Inflatable Aircraft Concept Be Updated/Modernized?

    That Aereon 26 looks pretty interesting - I couldn't quite tell if it's an inflatable aircraft, though it certainly has the look of one.

    Could the Inflatable Aircraft Concept Be Updated/Modernized?

    I was just thinking that this kind of vehicle could start out as an extension of the water sports market, with a small inflatable seaplane. The water sports market is already comfortable with all sorts of inflatable watercraft. So this would only be a small leap beyond that. The water sports...

    Could the Inflatable Aircraft Concept Be Updated/Modernized?

    What's going to puncture an aircraft flying in the sky? A bird strike? That could smash a windshield too, never mind just cause a puncture. People do hot air ballooning without suffering any punctures. People fly ultralights with fabric wings, without suffering any punctures. An inflatable...

    See this also: If you can dynamically adjust pressure using a compressor, perhaps you can even use that as an actuator, for variable geometry purposes. You might be able to deform the geometry by changing the pressure in certain inflated structures. If you're using a battery, then it could...

    Could the Inflatable Aircraft Concept Be Updated/Modernized?

    Back in the 1950s, Goodyear developed its Inflatoplane concept for the US military, using its newly developed Airmat technology. The idea was to create a collapsible/portable plane that could be airdropped to downed pilots for escape, but it was abandoned as alternatives like helicopter rescue...

    V-173 / XF5U - Flying Flapjack

    Okay, so the underside hatch is the nominal route, but the canopy method would be there as a backup. Why is it better to have the canopy on top though, when it restricts your view of the ground? Wouldn't it be better to have the canopy on the underside of your wing, to afford you a better view...

    V-173 / XF5U - Flying Flapjack

    Hi Christ/drive330, thanks for your reply, it gave me lots to think about. So let me then modify the goals/requirements I previously gave, and re-state them as: Safety + STOL + Speed + Range So I've added in safety as a goal/requirement, and I'm listing these things in order of priority...

    V-173 / XF5U - Flying Flapjack

    Ah, the good old days - back when we looked forward to flying cars: This one's narrower, and look at the nifty wide stance of its wheels: But I just thought of another idea. What if you take an aircraft like the Arup/Flounder/UFO, but you shift your cockpit & canopy farther away from...

    V-173 / XF5U - Flying Flapjack

    Going back to the UFO, I do wonder about the safety of an aircraft where you have to enter from below: https://www.homebuiltairplanes.com/forums/attachments/rowe-ufo-sport-pilot-mag-png.84909/ What if your undercarriage collapsed, say on a hard landing? You'd be trapped inside your vehicle...
