Default 'Canopy Wire Deflector Bars' - Past experience and current thinking

I thought the wire strike kits for landing accidents, couldn't stop before a wire fence and could hit the fence post. A wire strike while flying has a host of other difficulties. Helicopters commonly had wire strike kits installed, and as part of the kit that are cutters above and below the aircraft. I have seen swing tests of these kits, but would not want to try it myself.

I have personally know three helicopter pilots that hit wires, all three knew the wires were there and momentarily "forgot". This happened to me once, but I did not hit the wire. Did have a conversation with a glider pilot who while landing out observed the wires, planned a landing to ovoid the wires, then completely forgot his plan and that the wires were there, only remembered after safety landing and exiting the glider.

Bottom line: have wires as part of your off field landing check list: Wild Women Seek Sex, Wind Wires Slope Speed

does anybody have a viable design that will work with a modern sailplane?


Pure speculation.

For light gauge electric horse coral wires... Maybe a firmly mounted 'hook knife'mounted on a 12" whip to the fuselage just in front of the canopy might catch and cut wires (more often than not). Integrate it into an externally mounted Powerflarm antenna. Mount two. One on either side to get the sight blocking off center and gain redundancy (redundant antennas and cutter).
