So how exactly are these installations supposed to work effectively? Is there something I don't understand about the BRS's? :?

the rocket deploys the chute through the pilot, 8)

i mean seriously though wouldnt the first 3...assuming you chute doesn't get tangled in your tail feathers first....put you in a face first angle for the ground?? Or is that what the helmet is for?

The can position does not affect how the airplane hits the ground Chute fires out the flat side of the can.

It's how the kevlar straps are anchored to the airframe.

A lot of airplanes blow the chute out sideways or down and it has a long strap that connects to a swivel. This swivel connects several straps to the beefiest parts of the airframe with steel shackles.

You can hang the airplane from the swivel fitting on a new installation to see how it will impact. Using the landing gear to absorb some shock is best.

The rocket container has holes in the side to deflect the rocket exhaust 90 deg from the rocket tube.

One problem with most installations are they put the parachute handle on the cabin top or where you need to bend backwards to pull.

During a structural failure you may be pinned down by G forces and be unable to reach up to the handle. I like to use the lower instrument panel console between the seats so you have a easy rearward pull for the chute. The handle travels a good distance. It pulls up slack and then cocks a firing device before the rocket goes.

In an accident where the chute is not fired to deactivate just cut the firing
cable. Then it is safe.

I brought all our local EMS and fire dept to the airport and showed them how the rockets work, how to deactivate, Where the door handles, fuel tanks, fuel selectors on each type of airplane based here.

Good idea for any airport.

They have made a lot of changes over the years. The ones in the photos are the other way.

The 05 CTSW we had here had the soft pack chute in a fabric backpack looking thing.

Seemed fine for inside installations. I'm not sure why they switched back to the metal can. It seems like it would be heavier.

(move empty CG aft maybe? )

The give away is the rocket fires away from the actuator cable. you can see how the cable goes into the rocket housing in the photos.

Thanks guys...I thought the strap was contained in the canister and was attached to the canister mount or something and the whole housing was then supposed to be attached to a hard point. :roll: I did a little a more digging and found this diagram that pretty much sums it up I guess.
