Heavy Metal

close boss. we had these cars in our windtunnels at MegaMotors so ive seen em. tip vortices - at sea level and summer ambient temp tho - means that sum-gun is hauling a**. but dufferent question is whats the vortices' (theres a debate ) composition besides air?
so a hint: the thing i saw was "confirmation" of what the wing is doing FOR the car. its subtle but there
the "personification' of heavy metal.
i see films of its ancestors (Saturn V) taking off and literally get teary eyed
thx!

I seen the planes from about 20-100 yards depending where it was parked on the flight line at Barksdale AFB when I was stationed there. Lots of security around it always. As far as I know there are 2 planes that are the same and depending who is on board (POTUS) it becomes Air Force One.Suprised never had this plane here. Please .. no politics on this one .. just the hardware
My aerospace buddies say this is pretty good performance for a 747 .. those who really know say its UNDERSTATED. Nobody says its a Mach 1 airframe tho (need to nosedive to do it, then stuff starts coming off the plane).

Crew: 26: 2 pilots, flight engineer, navigator,[3] and cabin crew
Capacity: 76 passengers
Length: 231 ft 10 in (70.6 m)
Wingspan: 195 ft 8 in (59.6 m)
Height: 63 ft 5 in (19.3 m)
Max. takeoff weight: 833,000 lb (375,000 kg)
Zero fuel weight: 526,500 lb (238,800 kg)
Powerplant: 4 × General Electric CF6-80C2B1 turbofans, 56,700 lbf (250 kN) each
Performance
Maximum speed: Mach 0.92 (630 mph, 1,015 km/h) at 35,000 ft altitude
Cruise speed: Mach 0.84 (575 mph, 925 km/h) at 35,000 ft altitude
Range: 6,800 nmi (7,800 mi, 13,000 km)
Service ceiling: 45,100 ft (13,700 m)
I have seen the Marine One helicopters a lot also. Anytime there was a event close and they need a secure area to put the plane or helicopters they always use the closest Air Force base.
Biggest tanks ever designed.
That darn Fiat .. first car .. that thing was NOT something I wanted to be around. damn. maybe its just me .. but i have the feeling i woulda stood further away from machines like this at nearly 100 years old.
these 30-50Liter displacements -- if these folks had better design tools (air/fuel management, metallurgy, CAD/CAM) they mighta hit 15K horses outta one of these things.

The 18+ Cylinder crowd ... didnt know Detroit did a 20V and how they did was remarkable (to me at least).

Not necessarily heavy, but extreme for sure.

There is in that video Ponsse wood harvester and it's funny story how this harvesters get their name. They make first prototype early 70's and when is was ready ,it was so ugly that somebody said ;..what is that? It looks like PONSSE!
In that time Ponsse was name for one local stray dog and everybody knows that ugly bastard. Then the founder of the company knows that that's name of company!
Thanks for posting that,
Regards from land of Ponsse,

It's Not Going to Shift Itself
learned two things.
1. never heard of that specialty Electromotive rig just for tunnels
2. never heard of seen a sideboom dozer ... apparently common in the pipeline business?

a 1950B, built in the 1960's .. the "Silver Spade" -- in relatively recent times. A few are still diggin after almost 60 years.

When it went to work in 1965 at Hanna Coal in Georgetown OH
Still at it in 2003, retired in 2006 and finally breaking down on its last day of work.
"The Silver Spade, or Bucyrus-Erie 1950-B to use its model designation, was not the largest shovel built but was probably the most famous as the last of its type operating. With an estimated weight of 7,200 tons, she operated with a 105-cubic-yard dipper on a 200-foot-long boom, measured 59 feet wide at ground level, and reached a height of 191 feet to boom tip.
The behemoth shovel was served by a 7,200-volt trailing cable weighing 20 pounds per foot. On board, AC main driving motors totaling 9,000 horsepower drove DC generators for the shovel's main motions — hoist (8 motors), swing (4 motors) and crowd (2 motors). The massive weight of the machine was supported on eight crawler track assemblies, each with its own DC motor.
The 1950-B was built by Bucyrus International and started work in November 1965. Purchased by the Hanna Coal Co., a division of Consolidation Coal (Consol), for coal stripping in the Georgetown area of Ohio, she was named to commemorate the 25th anniversary of Hanna Coal.
The Silver Spade's final production day was April 3, 2006. After that, she proceeded to climb out of the final pit and head for a designated resting place. But before she arrived, a breakdown occurred on April 10 leaving the shovel dead in her tracks and marking the end of an era.
She had served her owners well during her active life, moving a total of 607,226,370 cubic yards of overburden. The Spade's final fate is unknown at the time of writing, but a local preservation group wants to see the shovel preserved as a tourist attraction.
The Spade and other giant stripping shovels built in the 1960s helped to lower production costs and boost an ailing coal industry. Now, with modern earthmoving equipment, that trend continues with coal currently providing over half the electric power generated in America today.

thats not supposed to happen ...

TOOOOO much boost
i woulda guessed a bad part .. in my car mfg days we blew up stuff on dynos (bad-***, exotic builds we were doing for pro-racing teams) that were post-mortem determined to be fatigued/porous, etc. that were otherwise spec'd/assembled properly for their duty cycle.
not arguing against poorly spec'd components vs. requirements, or shoddy assembly for this 3000 HP diesel debacle ... just my experience with failure mode analyses.
btw what in the world uses such an engine ... diesel "dragsters"?

I would guess a pulling truck. A guy I know has a Duramax engine for sale that is 1800 HP. He does truck pulling. The engine can be yours for the low price of $30,000.
guess if its got an engine, of any type, somebody is gonna drag race with it
Those boys need a lot more DEF!!
