That link requires the viewer to log in, was interested enough in seeing the video to click on the link but, not joining FB so, it's a no go for me. It is, what it is........... |

Bob, That's a different video, but basically the same thing. It's better, actually... The cutaway project is really cool, I've never seen anything actually building one.. The school I went to had an R4360 moving cutaway.....What a beast! https://www.youtube.com/watch?v=qpmOb46bvCs |

Hey Bob, Great post, I love that WW2 air tech and the tank stuff is cool too. Double Wasp, Merlin, and this Chrysler tank engine. https://en.wikipedia.org/wiki/Chrysler_A57_multibankThey took 6 slant six engines and married them up to a single crank. (actually they geared the cranks to a single sun gear) I saw one at the Walter P. Chrysler Museum outside Detriot. They have a Double Wasp here, saw that a few years ago. https://en.wikipedia.org/wiki/New_England_Air_Museum. Great museum at Bradley International Airport and worth the time and price of admission. |

Don't know about you Baldo, but it took me 5 years to get the oil out of my hands when I quit working on round motors. I do miss the rumble though.

Wow what beat the heck out of that piston? |

I found what was left of the valve in what was left of the supercharger. -RP On one of PBA's DC-3's, a connecting rod on an upper cylinder broke at the pin. That rod beat the living crap out of the cylinder skirt, belling it out all the way around. We were able to get the cylinder up a bit and got in there with a sawzall and cut the jug off. What a mess. I went on many a road trip for jug changes, a few times the jug cracked all the way around and blew right up through the cowling..I have some great pix, I'll try to find them. The funny part is I was actually avionics tech, but the mechs were shorthanded most of the time. I changed more cylinders than nav receivers....lol That was the best job I ever had. The money wasn't great, but the fun made up for it. |

You'd get the MAP up to about 45 if I remember correctly and that beast would scream. The collector ring was bright cherry red, you could see it all the way around the engine.... |

On turn flights, you'd fill the oil and check the gas....  |

R 1820-82 A. Powered the Stoofs when I was in the Navy. Was an emergency Gear tech-ejection seats A/C pressurization Oxygen and fire control-putting out engine fires in flight. But I have helped change jugs and engines and C S D units. Just couldn't loan those greasy mechs MY tools-no grease and oil around Oxygen. Ain't NUTTIN else in the world sounds like a round motor.

You'd get the MAP up to about 45 if I remember correctly and that beast would scream. The collector ring was bright cherry red, you could see it all the way around the engine.... The 2800s we had on the Convairs had ADI (water injection). Without the water on, MAP at full power was 59 inches. With the water on, you could go to 62 inches manifold pressure. I was doing a full power run one night and I forgot to turn the water on. I noticed the guys on fire bottles were getting pretty excited when I got up to 62 inches, so I pulled the power back. They told me that there were sparks coming out of the augmenter tubes going back about twice the length of the airplane. They said it was pretty spectacular. I told them I was just burning the carbon out. -RP |

One day my buddy was running it up to power right in front of the hangar after an engine change. He had pulled his rollaway out onto the ramp to work on it. Guess what...for whatever reason it started rolling, right into the prop. You've never heard or seen anything like it...  |

Please excuse my ignorance. Why the water injection ? For cooling ? And is it injected into the combustion chamber ?

NOT bein a smart azz water is one part hydrogen and two parts oxygen. More power and some cooling. In the late 60s early 70s some of the dirt trackers on alky had water injection. On dry nights you could hear and feel the difference. Know how well yer M/C runs on those cool damp mornings? RIDE SAFE.

Exactly. ADI stands for Anti-detonation Injection. You can only richen the mixture up so much to prevent detonation at high power settings. If you inject a little water into the mix, it'll cool it down a little so you can pull a little more power without getting into the detonation heat range.

Water cooled machine guns..... go longer before melting barrels (or jamming up badly). Very helpful with banzai attacks where barrel changes can get interesting.   https://s-media-cache-ak0.pinimg.com/originals/3e/57/a3/3e57a3be42ce0465ae9d7ebd451806ca.jpgWater is also helpful in our cars and bikes. Even helpful for plants and animals.  This fall my air cooled expensive chipper-vac got hot enough to blow a chunk out of the block (it was not low on oil). Now I have to buy another air cooled engine. |
