We developed a key-component for our “next-gen” recovery-setup. A small BP-charge is propelling a bolt with a sharp cutting-edge onto another blunt insert – cutting the cord in-between. Two of this devices are meant to release the main parachute by (redundantly) cutting a strong cord which is holding the lid over the chute-compartment.
Part-List: (EndCap; Fuze and BP-Charge; Cutting-Bolt with O-Rings; Body-Tube with Cord-Hole; Blunt Counterpart; EndCap)
Cutting Bolt Shape
The Cuttung-Bolt is made of SilverSteel but not hardened(heat-treated) this time and therefore “single-use”. Developement ongoing.
