Carswell, There ya go, tnx. and if you think the B-52s were loud you should have been there when the B-36s were. Found this: "The engines and propellers produced an unforgettable throbbing sound when the B-36 flew overhead. A friend of mine remembers the sound from his boyhood as a "captivating drone. The noise went down to your heels, it was so resonant. It just stopped you in your tracks. You looked up into the sky to try to find this thing, and it was just a tiny cross, it was so high." Others remember that it rattled windows on the ground from 40,000 feet." w3rv |

Thats about how high they would be when they came over our house some 200 miles west of Ft. Worth and the windows would rattle. It was an unmistakeable sound. Six a'turnin' and four a'burnin..... A good friend of mine who died too young was an engine mechanic on the '36 in the 50s, which prepared him for his full-time hobby of rebuilding the two Jaguar engines that he had - one was in his wife's "Saloon Car" and the other one was up on the hoist. Then they would switch. How many folks do YOU know who have a chain hoist and a full engine rebuilding shop in their 2-car garage? No wonder I could never interest him in ham radio..... -- 73 de K2ASP - Phil Kane |

Worth and the windows would rattle. It was an unmistakeable sound. One of the unique features of the B-36 is it's geared-down props, i.e., the props turn much slower than it's six big Wasps. The rotational speed reduction was necessary because given the 19 foot diameter prop disk the tips of the blades would go supersonic and all hell would break if loose if they turned at engine RPMs. I don't know of any other reciprocating engine powered fixed-wing military A/C which had geared-down props like the B-36 had. Seems reasonable to me to wonder if the B-36 also churned out an acoustic signature which was also quite unique in that from the ground they apparently sounded something like six "down to your heels" thumping overpowered military helicopters which I'm sure we've all heard in our neighborhoods. The little speck in the sky does thumps galore on the ground from miles away. With it's six big, unusually slow-turning props the B-36 it might very well be that it's acoustics were helicopter-like. Except a whole lot more so. Acoustics is radio in a different medium and frequency range. The results of resonance apply to both. The B-36 probably had an acoustic SWR of 1:1 at ground level. I never saw a B-36 in flight but I was there when Bell-Boeing V-22 Osprey airframe No. 8 arrived in the pattern over Brandywine airport in West Chester PA and flew it's last flight before being turned over to the American Helicopter Museum which is on the airport property. The V-22 also has monster slow-turning props and can fly like a fixed-wing A/C at speeds not too disimilar from B-36 speeds. I'm here to tell you the thing damned near drove all of us who were there that day thru the tarmac during it's high-speed demo passes. The Apache did not. w3rv |
