Can you post the photo on this thread?
Thanks |
Kindly send or post photos of your BRS install
Hello, wife says BRS is required equipment in potential new -9 build, so I'm looking at options.
Thanks Steve Campbell RV-6 (sold in '07) |
Light sport should be 1400 Lbs
This would be a good reason to move light sport to 1400 LBS
BRS Emergency parachute and a real aircraft engine. My view Joe Dallas |
Here?s one for the RV-7/7A and 9/9A.

A couple of real-world points to consider...
Glasair has developed a BRS for their popular Sportsman 2+2 aircraft. It is available fitted to the aircraft during the Two Weeks to Taxi program, or as a factory-retrofit for existing aircraft. It is not yet available for homebuilder installation. Here's a video of a ground test: https://www.youtube.com/watch?v=6NQRYkIcj4c Cost is about $34K installed, and about a 50lb hit on useful load. One area of design which I don't think I saw covered in this discussion is passenger safety as a result of energy-absorbing seating design. This is a very important area, and is a key ingredient in the success of the Cirrus system. In the case of the Glasair Sportsman, the seat cushion design is already well on its way to being a very good energy-absorbing design, and the overall crashworthiness of the airframe has resulted in several folks walking away from what would have been an unsurvivable accident in other aircraft types. If installing a BRS, please do give consideration to the seating and ensure it is able to absorb high vertical loads, lest you survive the impact only to have your spinal column crushed. |
Canadian-JOY, that's a very valid point. With the seats being (essentially) on top of the spar / carry-through structure in the 6s/7s/9s), there is very little room (just a few inches of seat cushion) for energy absorption. Might the 8 or 14 be a better contender; I think the 8 has much thicker seat cushions? Of course, routing the lines to the '4-corners' would also pose some challenges. Presumably, they'd run on the exterior of the skin covered with fiberglass fairings of sorts.
Frankly, I think Van's missed the boat in this regard with the 12 & 14. You folks likely read the recent article about the positive trend with Cirrus CAPs deployments. It's difficult to argue against a properly designed and utilized BRS system. In my case, the lack of a BRS offering may drive me away from taking on another RV project. Not to beat the proverbial dead horse here, but any additional technical insight regarding the energy absorption requirements and methods to mitigate spinal compression (or other probable injuries) would be much appreciated. |
rv9builder, Ah - thanks for the link to the offering in AS&S Co. Apparently, my line of thinking about routing the straps under fiberglass firings is already put to fruition.
