yeah,and it's hard to know how far back it goes.
Many years ago an uncle treated my oldest brother and I to a visit to the air museum at Chino Airport,California (flying cars).
They have a WW-II Soviet YAK fighter,with an active rotating-radial vanes within radial vanes style grille-blocked radial engine.Really elegant engineering.
I was serving at Eddy's Airplane Patch at the time,and immediately flashed to the air-operated shutters on our Brockway bob-tail tractor-trailer radiator.
As Alex Tremulis would say,"what's old is new again!"
