When designing an aircraft to have a BRS system, what must be considered?
Where would the BRS and the harnesses be located relative to the center of gravity?
In some pictures with deployed BRSes, the aircraft is fairly horizontal to the ground and I see multiple (3 or 4 usually) lines running from various locations on the fuselage. Other times, the looks like there is only a single line attached at one point and the aircraft is pointed downwards.
A single harness is likely much simpler but isn't as stable and holds the airplane at a nose all-the-way-down attitude. Multiple harnesses require a more complex setup but tends to hold the plane at a much better attitude than nose down. And since the surface area of the bottom of the plane is much more than the surface area of the nose, impact forces will be reduced.
For this BRS-5 system, it looks like there is one harness or riser extension. Deploying the BRS would be simple enough and probably just requires a panel to pop out and the BRS then shoots out. The harness would be attached to some under the panel, near the BRS system.
In the case of multiple lines attached to multiple points, just where are the lines located when the BRS is not deployed? How do they come out once the BRS is deployed?
