Corky Scott I wasn't implying that a catastrophic coolant failure was a likely event, but rather that this was an unlikely PR angle. Eric |

There has been one incident where there was a sudden and complete loss
of coolant. The builder had capped an unused hose connection on the block by folding a short length of heater hose in half and hose clamping everything in place. Though the engine's head gaskets had not been set up as recommended the plane had more than 800 hours on the meter. The builder had no problems to this point because of his procedure of fully bring the engine to temp before requiring take off power. This day he neglected his own warm up rules and took off before full saturation. The head gasket blew pressuring the coolant system. The pressure peak blew the clamped hose plug and instantly emptied the coolant from the engine. After trying to find a hole between traffic on a couple of highways the pilot was flying parallel to traffic on his intended landing highway when the engine quit. Flight time since loss of coolant at that point was 15 minutes. The pilot and passenger in the Mustang II skidded on top of a fence beside the road for several yards then tipped over into a water filled ditch. Because of the recently installed roll over structure he and his passenger walked away. The plane had minimal damage and was quickly repaired. The engine when disassembled was found to have not seized. Nothing wrong could be found in the engine. After several days of running the engine the builder finally discovered that the culprit was a water caused short in the ignition system and steps were take to eliminate that weak point. This incident is the only instantaneous loss of coolant of which I am aware. Point is that sudden loss of coolant does not suddenly stop the engines power making capability ....as would loss of fuel or loss of oil in this or any other engine.

They did a couple of experiments of running the engine, with a prop, without coolant. On both occasions the broken-in engines ran for 30+ minutes. Both stopped due to expansion of the pistons in the bores. When the engines cooled the coolant systems were filled and the engines started. Both ran and turned the prop at the same rpm. But also both engine's head gaskets were shot and the metallurgy of both the heads and the pistons had changed to the point of all having to be relegated to the scrap pile. Crank and rod bearings were still in good condition. Bruce A. Frank ++++++++++++++++++++++++++++++++++++++++++ What RPM? What power level?

Keep on spinning away... with talk of minimal damage, etcetera -- Barnyard BOb -- KISS - keeping it simple, stoopid I recall Bill Phillips posting a story about test flying an RV (6 I think) on it's initial flight. Bill agreed to make the flight for the builder. The builder went with Bill on the flight, if I remember correctly, although that fact doesn't matter in terms of the story. The engine was a brand new Lycoming, again, if I remember correctly. It blew out the front seal of the engine while in flight and emptied all the oil everywhere, including the windshield. Bill managed to get it down amidst a rock strewn opening in the desert, with minimal damage to the airplane and engine. This was an air cooled engine, he did not have 15 minutes to get it down. Corky Scott PS, I don't see Bruce's post as a "spin" on the subject. Applying a spin to a story implies twisting the facts to better suit an agenda or to explain away ill thought through utterances. What Bruce was doing was showing that yes in fact there had been a sudden and catastrophic loss of coolant in a Ford powered airplane, after I'd said I did not know of such an incident. That the engine was not damaged, even after flying for 15 additional minutes after loosing all it's coolant isn't "spin". It's what actually happened. |

Otherwise, your remarks here are fair game for one and all. IF you and Corky ever ACTUALLY FLY your conversions..... maybe your FACTS? will take on a more realistic perspective. So far, you vocal RAH conversion advocates are ALL TALK and NO WALK. ALL HAT. NO CATTLE. You guys point to what you believe are 'successes' defined by some 'shoot from the hip' criteria. MOSTLY what I see is...BULL****, so the flags go up. If this is "BESTING" you, so be it. I make no apologies. Worth YOUR indulgence? Pardon me all to hell, your majesty. While you and Corky just talk, talk, talk.... I continue to walk my walk - just like I have for 50 flight years. Why should I give a rat's ass if you never INDULGE me, again? When you two scare the **** out of yourselves sufficiently, AND YOU WILL, I believe you may 'indulge' me... ....IF you survive your follies and your egos. Barnyard BOb -- over 50 years of flight. |
