'Parafoil vertical lift mechanism'

[Quagmirian 40]

Anybody know what this is? From the drawings it looks really... odd.

Great Scott!
A ram-air triplane!
I'd really love to see the deployment sequence. Or come to that, the packing procedure of one of those...
Though I like the idea of parachutes on a truck. Anyone care to take this thing to Bridge Day?

It's not a parachute ~it's a 'Lifting Devise'

I don't know about the "Lifting", but it is certainy a "Devise".

I second the "Great Scott" exclamation.

Dam you Red Baron, you're back again.

U only make 2 jumps: the first one for some weird reason and the last one that you lived through. The rest are just filler.

Twardo, you probably have a harness/container somewhere that could handle the pack volume.

Please don't dent the planet.

I thought the 'truck pic' WAS the harness & container!

Looks like a CRW rig for somebody with no friends.

Might have been designed for the military for their equipment to cross damaged bridges etc.

The equipment provides the fwd speed the tri plane provides the lift.

If the drag wasn't too bad the lift would lighten the load for better gas mileage!

Triplanes only enjoyed a short service life, near the end of the First World War.
Sopwith's Triplane was only manufactured during 1917 and was soon replaced by (biplane) Sopwith Camels.
Fokker only built DR1 tri-planes between id-1917 and the end of the war. Fokker triplanes were unstable ... er extremely manuverable ... but slower than contemporary biplanes.
No tri-planes were manufactured - in significant numbers - after WW1.

[riggerrob 643]

The primary disadvantage of biplanes and triplanes is that the high pressure area - below the top wing - interferes with the low pressure area above the lower wing.
This interference reduces lift and increases drag, steepening the glide ratio.
The only reason early airplanes were biplanes, was that biplanes could be built much lighter than mono-planes.

I always wondered where ground launching originated.
