QuoteHello all:
Thanks Les for the pictures. I must admit that seeing your photos and those from Courville made me feel a kick to the gut. It's sad that someone in the business could not see a way to keep her going. We thought maybe TWT could have become a co-op, if not outright ownership by some company for the price of the property. It's doubly sad that someone made the decision to allow that unique test facility to fall to the knackers. Shame on UCLA.
I have wondered if the wrecking team had any idea how many cans were in the tanks. The cans are of interest to several folks. I have pal, ex-B-1, who sent an email asking about the cans and heard comments that the cans were still shiny, no rust.. Yes the air was very dry, thanks to that gas fired air dryer that was a pain in the arse to keep in operation.
Here is some trivia, FYI: How many cans? According to my notes, there were 135 rail cars (open gondolas) full of cans. Some one calculated their weight as 1,500,000 lbs! (I did occasionally wonder if a tank seam weld failed, would we spew cans all over El Segundo? ) As most know, the cans provided temperature stabilization for the air. The air was hot coming out of the compressors, cooled by the intercooler and after cooler, but still about 100 F. (as I recall), as it went into the tanks. During during a blow, the air cooled due to expansion. Having extremes in tunnel air temperature, blow to blow, would be unacceptable. So, to provide better temperature stabilization, tin cans were selected by those smart NAA design guys during the early 1950s. They looked a several concepts, rings, steel shavings etc. and settled on tin cans. The tin cans were mostly without ends, just tin cylinders, to provide massive surface area as a heat sink, while taking up minimum tank volume. (Tank volume was 214,000 cu. ft. ) We could see the cans by entering the big manifold and going up to the tank outlets where cans were retained by grating. There were lots of juice cans and beer cans. Remember Lucky Lager? They were there by the thousands, with the big X still visible on the labels.. There was a funny story about buying the cans. Seems NAA talked to a major can mfg. (maybe American Can or Continental Can Co.), and made a deal to buy cheaper rejects. After having several RR cars of rejects delivered, an executive from the can company called NAA and says "What is an airplane company doing with all our rejected cans?" He was told and said he would like to see the job. He came on site, and watched the conveyor dump all those cans into the top hatch of a tank, then said something like "Dang we have lots of rejected cans!". He goes home and tightens up the manufacturing process so much that the rejected can supply tapered off. NAA, with a schedule to meet, had to go to another can company to supplement the initial purchase. I'm sure Dick Leef has a bunch of early TWT stories, and is one of the few who can add to, or correct this story.
I was sorry I could not be there for the TWT "wake" and last blow in September of '08. I certainly thought it fitting and proper that Dick Leef, ("Mr. Trisonic"), was there, the only person who saw the very first blow in 1958 and the last blow, some 50 years later. Trisonic Wind Tunnel was an outstanding facility, no matter what name was on the building or data, NAA, Rockwell International, and later, Microcraft or Allied AeroSpace. She was a tribute to all the exceptional folks who kept her afloat all those years. I am honored to have been a small part of her history and to have worked with so many wonder people, including staff , associates and customers.
