B-29 "Doc" number 4 engine static start

[badmoonryzn]

WOW! What a great sound. I remember flying on one of the Constellations and hearing those wonderful engines all the way from Indy to LAX. We stopped somewhere and changed planes. I was only 5 but I will never forget that wonderful sound when those engines were started up one by one and then hearing them under a load for take-off. I was so lucky, as my pop worked for the FAA and we flew often. I got to go up in many airplanes. It is so quiet now in the airliners of today. Thanks for the video!

How is the bottom cylinder lubbricated? It seems like the oil would drip down into the combustion chamber.

[1995MartinD40FMG]

Can't wait to see Doc in the air with FIFI !

[Fennec2828]

@crispycritterz Only the early production engines had that problem.Once the "combat" engines made their debut the most serious problems had been solved.The early cylinder barrels were the prime cause of many of the fires.The R-3350 served in many aircraft including airliners such as the L1049 Constellation and the DC-7C Cloudmaster to name just a couple.

[crispycritterz]

Those Wrights scare me. They had a nasty habit of catching fire for no reason.

[distructor20]

that's one powerfull lawnmower.

I think this is amazing that there are people restoring an old plane like this

[RSBSTEADICAM]

When shooting these things, turn off the "shutter" feature in your camera for a much more natural effect. The shutter is causing a stroboscopic effect which (seems to) stop motion or (worse) making things seem to go backwards. Just a hint for all your wanna be historical film/video makers out there!

[BronzeGiant]

I REALLY do not like what digital cameras do with propellers.....

[crazyfvck]

@BronzeGiant Yeah.. It does make them look pretty weird.

[mjmikelson]

Pretty sure the APU provides the power to start the motors spinning too, no battery out there's going to provide enough electricity to do that.

[TheBrokenWing1]

ok, i dont know much about these amazing engines.....what exactly does the APU do?

[volodymyrm1]

@TheBrokenWing1 APU- auxiliary power unit provides power for the engine to start and electronic components when the engine is off i.e car battery/ a little jet engine in the tail of 747 solar panels on the space craft a piston engine with generator/ alternator on it that produces power for a main engine and electronics shit like that

[TheBrokenWing1]

@volodymyrm1 ok, thanks! i thought it had something to do with the cooling system, or maybe some kindof oil pressure pump.

[volodymyrm1]

@TheBrokenWing1 yea as much as i know APU only provides sparking for cylinders and power for on-board electronics

[smokingws6]

@volodymyrm1 In this case the APU is only a 28v DC generator.  B29's use standard electric starters. Magnitos are not tied into the electrical system.

[kirkconway]

Incredible ,

3350's are really something, to hear and watch run,

[cs512tr]

nice, was waiting to hear it at full rpm or so

still awesome

:)

[playerdepimp]

uhmmm it looked as if the propellers were bent, i guess not then, i hope it flys once again!!!!!

[Milstar73]

How do you reverse the prop rotation? That doesn't seem possible.

[darkhound891]

@Milstar73 the reason it seems to do that is bc the prop is moving so fast it seems to slowdown an reverse direction

[ponkkaa]

@Milstar73 Prop reversal is an optical illusion caused by the camera's shutter frame rate. Try moving your hand back and forth rapidly in front of a fan blade. the blade will look like it stops and starts.

[BlueWaterBoat]

@ponkkaa Its also referred to as reticulation.

[ponkkaa]

@BlueWaterBoat Hey! Watch your language!

[jeeprcks]

Wright Cyclones are my favorite...listen to that sound! :o)

[spikonaleash]

sounds bad ass, hay put that in my truck lol

[VFA103JollyRogers]

Will Doc fly again?

[kansasflying]

That is the plan. I think there might be some $ issues right now. I sure hope it flies again!

[vabch82]

@kansasflying isn't fifi the only flying b29 right now

[TBM3EAvenger]

@vabch82 FIFI has been grounded for some years now but she now has 4 brand new engines and will return to flight once testing is done

[ghostrider02100]

four stroke singel

[rusttrail3]

Sweeeeeeeeeeeeeeeeet

[kansasflying]

I am not too sure...

[Bergstaller01]

I cant remember if the APU is a 2 stroke or a 4 stroke engine.

[Awesomeman1987]

it sounds like a four stroke

[Bamchucknorris]

@Awesomeman1987 it is a 4 stroke, 2 valves per head
