Ballute design Copenhagen Suborbitals
http://www.wired.com/wiredscience/2014/01/bastard-named-ballute/

"We just initiated the Ballute design-phase and we have already created the very first prototype which seems like a promising try-out model."

Ballute requirements and functionality
Basic data: Ø600 mm, drop shaped, Nomex.
Velocity range: 0 to 900 m/s
Pressure range: 0 to almost 1 bar
Temperature range: up to 650 K
Aero-breaking: negligible (used for attitude control)

Would these ballutes be more useful for entry and landing, aerocapture/braking, or both if perfected?

Prior to landing to keep the vehicle orientated. Made from the right materials it COULD be used during entry but aerocapture velocity is probably going to be way to high. I actually wonder what speed they are looking at using it for? It doesn't look to me like a high-speed design.

(FYI: I've experiance inspecting, packing, and attaching super-sonic and sub-sonic ballutes for air-dropped weapons and that's where the question is coming from)

From The Amazing Catstronaut on the Black Arrow LV:
British physics, old chap. It's undignified to belch flames and effluvia all over the pad, what. A true gentlemen's orbital conveyance lifts itself into the air unostentatiously, with the minimum of spectacle and a modicum of grace. Not like our American cousins' launch vehicles, eh?

From the article they seem to have two models one for the test this summer
"For the 80 kg capsule, for summer 2014 space-shot, there is no need for main parachute since the drogue itself will provide a terminal velocity of 11 m/s at sea level.

In short, the TDS80 capsule will deploy a ballute at apogee (app 100 km) creating a steady re-entry all the way to 3 km. At this altitude the capsule itself has a terminal velocity in the range where we can allow for the drogue to be deployed."

I guess their testing with an 80kg capsule since Felix Baumgartner is retired. Hope it works and Stratojumping becomes common.

Found an offshoot company off of our friends from  Copenhagen Suborbitals

Not sure if this video link will work or not  http://tinyurl.com/qhtaj5c

"Men building homemade rocket ship in backyard

Two men from Denmark are taking doing-it-yourself to a whole new level by creating their very own space program in a backyard shed. They plan to blast off into space with a homemade rocket. NBC’s Keir Simmons reports. "
