I assume we are talking about hard chroming, not ornamental chroming. I've never seen hard chrome flake, even in pretty severe environments. The biggest problem would be in developing land profile. Wi ...

For that application chrome would usually be seen as superior due to its resistence to corrosion and high temperture erosion . One of the fixes to the early M-16 problems was to chrome plate the chamb ...

In general, a chrome crank offers a harder, lower friction surface. The biggest advantage is that it can be used as a repair technique on a single journal without re-chroming the entire crank, with a ...

Well, here goes with more data points which do not agree. In the book " High performance automotive fuels and fluids" ( author is Jeff Hartman ) there is a table which gives a RON of 109 and ...

If liquid cooled engines are so superior, why are all the successful, high horsepower ( 3000+ hp) engines air cooled? Also, did any high performance liquid cooled engines ever equal the s.f.c of the t ...

Two different nuclear propulsion schemes were pursued. Pratt Whitney worked on an indirect cycle engine, but never built a working prototype. General Electric built direct cycle engine ptototype, the ...

Very interesting observation. A similiar situation existed in drag racing in the late 70's. In the Top Fuel and Funny car classes, Big Block Chevrolets were very common, and were competitive. When the ...

I have access to a 605 D installed in a Bf 109 G-10 if that would be of any help. I also was interested in cannon installation in the 109, specifically if it was possible to install a mk 103. After lo ...

Does anyone have any details on the USAAF/USN use of N2O ? A long time ago I read that the USN tried H2O2 injection very late in the war on fighters, but have never seen any other mention of it. Has a ...

Are there any in museums? ( Hopefully on the West coast !! )

Do any two stage V-1710's still exist? I would love to see one in person.

Graham, I agree with you 100% about the charisma thing. What I am proposing is that turbines be allowed to be competive - NOT dominating. Only a very few people would want to watch an all turbine pow ...

I was aware of the rule restriction for the unlimited class. I think this is the exact subject that needs to be discussed, as it seems to have a direct bearing on how much longer we will see the pisto ...

It crashed at Reno in 1993, due to an engine failure. Probably one of the most controversial airolanes to ever fly, as people are still flaming each other wether or not this was a genius design or ano ...

Is there any sign that there is movement away from the "legacy" aircraft that we have been pounding away for so many years? Surely, we must be appraoching a time where the economics of purpose built ...
