Narrative:
Shortly after intercepting glide slope at 3;000 feet MSL and 210 knots assigned on the ILS runway 36L and autopilot engaged; aircraft experienced a very rapid 60 knot wind shift from 50 knot tailwind to 10 knot headwind in less than 20 seconds. Aircraft rapidly accelerated beyond the config 1 flap limit despite full speed brakes. Disconnected autopilot; pulled nose up; slowed and executed a go-around. Landed uneventfully on second approach into clt.leading a small pack of aircraft; we were assigned a faster than normal speed for IMC conditions close to CAT I minimums. My first officer (first officer) and I noted the 50 knot tailwind and discussed the impending wind shift. But we expected it to be much more gradual and had no idea the shift was so sudden and severe. We did not receive any alerts from ATC or other crews about the nature of the impending shift.in the future I would recommend being more proactive in querying ATC about the shear location and severity and ensuring a speed much farther below the flap limit so as to be able to accommodate the speed increase. While I have had tailwinds on final in the past that transitioned to a headwind before landing; I have never had a 50 knot tailwind basically disappear and become a headwind so suddenly while on glide slope. I would also recommend to all aircrews that anticipate losing a tailwind on final that they lower the gear much earlier than normal to provide additional drag to help fight the acceleration.
