OT: Totus, NEW Aerospace/Commerical SST Lockheed story for You....

[Mattingly23NY]

Tom have you heard or read of Lockheed's 'new on the drawing board', SST-80 Passenger Jet? Still in Design mode, and will fly from LAX to JFK in but 2 1/2 hours. The one thing I read, that somewhat puzzles me, is a "noise reduction" process, which just makes no lick of sense to me, since Noise Suppression of Jet Engines cannot stop a Sonic Boom, and we all know that. WTF is Lockheed thinking? I'll fill you in when I get that far. I think its bullshit to think they can stop an airframe from breaking the sound barrier, without sonic booms, by simple engine noise reductions. In other words, yes, Lockheed's Spokesmen of course don't usually know their asses from a toilet seat, in public forums.

Especially when it comes to the specific details of a new program....

On the B2, we did develop a Non-Contrail and Non-Heat Signature out of the B2's powerful 4 each, 50,000 lbs thrust engines. That much was actually an easy task of design. Yet, its still one of several features on that great bird, that still remain at the TSAR level, and will be til no more B2's are flying.

BTW- I'm going to see Interstellar on Friday, I'd enjoy having a convo with you on that flick...!

Interesting. Heck my 54mm minimum diameter rockets flying on a K250 engine would 'pop' during mach transition. My all carbon airframe weighed a hair over 2lbs...the engine was 3lbs, lol! Sucker would max at Mach2.5 and soar to 25,000'. Lit one off for a buddy who was cruising a lot with his wingman in their F18s out of Miramar. They were tuning their plume section systems, we were mock SAMs. We all felt pretty proud a few months later when his squadron went downtown Bagdad.

Not sure why they need to suppress sonic booms....they take off to the west, just pop the cork feet wet and their turn east.

you guys know this, but how can someone say that "noise reduction" stops the boom? It's a pressure wave emanating from the leading edge, right (at least, in "traditional" airframes--I won't speculate on your high-side stuff)

Very Impressive. Do you ever launch your Rockets at El Mirage Dry Lake Bed? If so, let me know one weekend, I may be able to make it over there, that would be a site worth seeing. You've built some incredible rockets, as a hobbyists, you know if Aerospace were booming like in the 70s-90s, Rocketdyne would be calling you. You could work your day job, then do 2nd shift designing new Titan Rockets or other Delivery Platform Rockets, THE NEW AGE OF ROCKETS. 2LBS Composite Vehicle, WITH A 3LB ROCKET. Holy Moses, look Martha, Armageddon has started without us....The Russians are coming...! (or Chinese), hell some might think Saddam with his Scuds is still alive, another Conspiracy Theory....!

Exactly either way from LAX to NY or vice Versa, no need to suppress Sonic Booms....like you said. Hell, I don't even see a strategic need to suppress the unsupressable...perhaps a pander to create a bottomless gut of R&D money out of the Govt-DOD coffers. Makes not a lick of sense.

I'm jazzed as hell to see Interstellar...!

Hey Rob....I'm on a flying hiatus. Hope to jump back in a couple years, want to play more at Black Rock....100,000' altitude waiver. Real fan of boosted dart engineering....energy transfer - potential to kinetic. Also an entry point to building a micro scramjet.

I think its bogus to keep the tree huggers from suing.
