Heavy Metal

[amazinblue82]

Stumbled across this...maybe been here before of you folks know of it. i thought i saw it on TV once 5-6 years ago?

yeah, a Chebbie, but with a V12 Merlin. 3,000 ponies..that'll part you hair. Not "Heavy" metal like an M1 Abrams tank, but "Heavy" as in awesome.

I feel two-ways about these airplane-engined cars... if i had the lettuce I'd never do it (better things to spend $1M bucks on - like a real vintage P-51 Mustang), BUT I come down on the "Wow. Cool" side from the ingenuity/engineering to get it to work in a car.

Been there, 4 years on the USS Hepburn FF1055, not a carrier but we did chase them around doing plane guard quite a bit.

Neat ship. Plenty heavy enough for me .

USS Hepburn, Knox-class frigate, overall length 438 feet (133.5 m), a beam of 47 feet (14.3 m) and a draft of 25 feet (7.6 m). They displaced 4,066 long tons (4,131 t) at full load. Their crew consisted of 13 officers and 211 enlisted men

The ships were equipped with one Westinghouse geared steam turbine that drove the single propeller shaft The turbine was designed to produce 35,000 horsepower (26,000 kW), using steam provided by 2 C-EBoilers, to reach the designed speed of 27 knots (50 km/h; 31 mph).

Largest Diesel Engine in the World. Tips scales at 4.5M pounds, 108,000 horsepower, 5.5M ft-lbs torque.

http://www.amusingplanet.com/2013/03/the-largest-and-most-powerful-diesel.html

This is RT-flex96C - a two-stroke turbocharged diesel engine designed by the Finnish manufacturer Wärtsiläand is currently the largest and most powerful diesel engine in the world.

Standing at 13.5 meters high and 26.59 meters long, it is almost as big as a small apartment. It weighs over 2,300 tonnes and its largest 14-cylinder version produces 80,080 kW of power.The 14-cylinder version was put into service in September 2006 aboard the Emma Mærsk, a container ship – the largest at that time. The design is based on the older RTA96C engine, but revolutionary common rail technology has done away with the traditional camshaft, chain gear, fuel pumps and hydraulic actuators.

One of the most remarkable feature of this behemoth is the high thermal efficiency, which exceeds 50%. This means that 50% of the heat generated by burning fuel is converted to power. For comparison, most automotive and small aircraft engines can only achieve 25-30% thermal efficiency. Even at its most efficient power setting, the big 14-cylinder engine consumes 1,660 gallons of heavy fuel oil per hour.

Bore: 960 mm
Stroke: 2,500 mm
Displacement: 1,820 liters per cylinder
Mean piston speed: 8.5 meters per second
Engine speed: 22–102 RPM
Torque: 7,603,850 newton metres (5,608,310 lbf·ft) @ 102 rpm
Power: up to 5,720 kW per cylinder, 34,320–80,080 kW (46,680–108,920 BHP) total
Mass of fuel injected per cylinder per cycle: ~160 g (about 6.5 ounces) @ full load
Crankshaft weight: 300 tons


The Emma Maersk..all 1300 ft, 110,000 tons of it

And there's no cats on it?

All in all..the proper place for a Merlin. Interesting story on the engine AND of course the plane at the link below.

http://acepilots.com/planes/p51_mustang.html

Side-bar: first airplane I EVER recall talking to my Dad about (he kept calling it a "mustang"-- at six years old I thought it was horse), and first model airplane we built together.

It represented his greatest dream UN-fullfiled. He wanted to fly the P-51..but he was born in 1933 so that just wasn't early enough. Korea was his war..in the artillery..right outta high school.

In a powerplant in Copenhagen. made by Burmeister & Wain, now of MAN B&W Diesel. Cool.

The largest of the engines, which was built in 1932 and re mained the world's largest for more than 30 years, stands 12.5 meters tall and 24.5 meters wide and weighs 1,400 tons. It produces 22,500 HP and supplied Copenhagen with electricity. It remained in use during peak demand until the 1970s

Cant find this beast...what is it?

USN hovercraft. Largest in the world.
Of course those are Marines invading the beach while the sailor boys are playing Minecraft....

That's her now resting at the bottom of the Pacific. That picture was taken either while I was on it or after I got out, because the hurricane bow was added while I was on board. The fastest we had it going was 31.5 knots, whole lotta shakin going on.

i didnt serve so i gotta stay outta the "swabbies and leathernecks" thing

yeah, ignominious end for her. bet she was a fine ship. thx.

World's biggest dump truck. Belaz 75710. Russian made. 4,600 HP, 720K lbs empty, top speed about 38 Mph.

The 75710 can carry a 500 short ton load. The empty weight is 360 tons - much more heavily built than the previous model, which was 240 tonnes. It is 20.6 metres long, 8.16 metres high, and 9.87 metres wide.

Instead of a single engine, the Siemens MMT 500 drive system (with AC/AC diesel-electric transmission based on the ELFA inverters) is powered by two 65-litre 16-cylinder diesel engines, each with 2300 horsepower 2 engines working together give a power of 4,600 hp.

Fuel consumption (according to company data) is 198 g/kWh per engine, with option to run on only one if carrying less than capacity loads. Maximum speed is 64 km/h, and economy maximum speed (when fully loaded and on a 10% gradient) is 40 km/h.

Even though I intellectually knew it would take-off, I admit to a thought that "No way that big-a** thing gets off the ground". (ala the "Spruce Goose" ..which "technically" flew I guess).

And there's only ONE of them in the world. Antonov An-225 - Russian-built late 1980's.

The "Spruce Goose"..Howard Hughes' famous (infamous) wooden (made out of birch actually) airplane.

Lots of info on it out there if you have any interest. The H-4 "Hercules" flying boat.

Flew once in 1947, got about 60 ft. in the air, never flew again. Soon after, Hughes' personal descent into madness accelerated (truly a sad tale).

Longest wingspan of any plane ever built tho...to this day beating our Russian friend above by over 20 ft.

Test Pilots..gotta love 'em.

The infamous barrel roll Tex Johnston did in the Boeing 707 prototype. its 1955 and the 707 was a BIG plane -- physical size AND importance to world aviation (and Boeing).

Always a crowd-pleaser at airshows...IF its allowed. The high-performance takeoff with afterburners lit.

This might draw snickers..but I have lived a long time NOT knowing what that thing on the end of a heavy weapon's gun barrel is - let alone what its used for.

a muzzle brake.

first finding out what is was called was easy via Google - "whats that thing on the end of the tank barrel called?" hundreds of thousands of listings come up.

why it works was the revelation to me and was from a basic law of physics i learned in high school 40 years ago: conservation of momentum. then it all made sense without reading much more.

the muzzle brake helps management of recoil (perpendicular to the barrel, making the barrel tend to otherwise move off the target after a shot) caused by escaping propellant gasses. in turn that improves accuracy under rapid fire conditions.

 

[amazinblue82]

I never tire of this magnificent machine. Only saw it fly once in person...wish i could have been there for every launch.

this is the first of series of videos slow motion/in-close from the pad --- longish but narrated by NASA engineers who worked on the program. the remaining parts are on You Tube if interested
