NASA Spiral Duct ESTOL Concept

Extremely Short Takeoff and Landing advanced vehicle concept based upon the coupling of the Lippisch Aerodyne and Custer Channel Wing. Designed to takeoff of at a speed of just 30 mph, with ground distances of less than 150 ft. The outer panels are freewings (able to freely pivot) so that the vehicle is less gust sensitive (which is a major ESTOL problem). Developed as part of the NASA Personal AIr Vehicle project under Mark Moore.

If a bird does hit a propeller, most likely the propeller will simply chop
the bird in half or bounce off. Show me cases of birds taking out
propellers (not turbofan engines - props). I have looked and there are very
few cases (with far more for turbofan engines). But if for some reason the
prop is not spinning, it will glide, but not be able to land in a very
short distance. This is why the powertrain system is fully redundnat with a
small cruise IC and electric system.

@leloodallasmultipass Yes, I am aware of software simulation; this is
obviously *not* that. How can I tell? Easy... *it only rolls across the
floor*. No aerofoil movement, no simulated air flow, no explanation of any
aeronautical benefits. Nothing. I could mock this crap up in Blender (for
free), and, again, it means *nothing*. Again, show *anything* that shows
that this thing *might* fly. And stop being condescending, its childish and
self-righteous; you don't know my background.

They could become something of a "lifeboat" for large bombers, & could
actually be launched in the same way as the bombs themselves. They could
also become lifeboats on a re-created airship industry, so events like the
Hindenberg wouldn't have such a high death-toll if they happened again.
There are a large number of uses for a small aircraft with deployable
wings, the ability to lift at only 30mph, & not needing a long runway to
get into or out of the air.

I like the design and concept. My questions are firstly, couldn't the duct
provide enough lift, without the side winglets? Follow on question,
wouldn't all the hardware (read; mass) needed to stow them be
counterproductive in response to P/WR? Still on same subject, the KISS
Principle would also be effective here, what with adding mechanisms to
break down. And secondly, piddling all over my quotation on the KISS
Principle, could/is the thrust be powerful enough to provide a pivot for
the cap

Good point, co-axials offer a lot, but require quite a bit of separation or

I see where the Custer channel wing comes in, but I'm not seeing a large
influence from the Aerodyne. Are their resources through NASA where I could
learn more about this design or resources you would recommend for learning
more about the Lippisch Aerodyne? Also how does the aerofoil change shape
in the design? Is it more like a connected biplane with low pressure
regions both above and inside the duct or is it a circular wing with the
only low pressure region being inside the duct?

I don't understand, the propeller is completely shielded by the wing -
which is one of the key features of this concept. How would you possible be
hit by the propeller unless you crawled into the propeller? Besides, you
wouldn't even get in or out of the vehicle with the propeller turning.

Author TheCaracatusPotts (3 years)
Sorry, original post did not include all of Q2: Secondly, piddling all over
my quotation of the KISS Principle, is/could the thrust be powerful enough
to enable vertical flight, if the capsule could pivot? All this is beside
the point? Where can I order one from????? :-))

Author CI9TK (3 years)
I get the duct effect on the rear control surfaces at low airspeeds but
this looks like a lot of wing/lift-surface loading for any craft able to
carry engine, pilot and landing gear.

Bird strike is not a significant issues for ducted props - much less so
than turbofan engines. The gradients are less strong, to permit a bird to
move out of the way, and even if it does go through, the contact area is
less than 20% of the disk area - while a turbofan is 100% capture area with
the bird having to be chewed up in the compressor, combustor, and turbine.
I would much rather face a bird strike in this, than a turbofan bizjet.

@NASAPAV Well, he had a point. Use some foam or fiberglass - or wood - buy
an RC A/C motor, build a scale model about a foot long, and see if it works
in the real world. Cost ya a couple hundred bucks, tops - plus your time.
Science: Propose a model. Test your hypothesis in the real world. Make
adjustments to your hypothesis, if needed. Test again. If a small scale
model works, scale up - and test, again.

Sorry.. very tired of seeing computer mock ups... you could have painted a
rock with chicken wings, and it means NOTHING. At the very least, build a
small proof of concept model with fiberglass, a lawn mower engine, and some
remote control actuators.... otherwise, nobody you are attempting to show
off to has ANY reason to believe this thing would fly.

Do the calculations - optimum wing span for a 600 lb aircraft flying at 130
mph is about 15 ft. Which is what it is. Now, that means you have to build
the aircraft to have a 300 lb empty weight. But look at the Rutan Quickie
aircraft. About a 15 ft span, and about 250 lb empty weight. That's the
idea - but this specific version of the concept is challenged with
excessive wetted area (which turns into weight!)

Doesn't this need a bigger Fuel Tank? If it is a PAV. Would that not
increase live load or whatchamacallit? Add a little luggage and I winder
how heavy it would be. Can a ESTOL PAV then still be made? Or would it end
up being a helicopter essentially?
