Earlier today, I was talking with a gentleman about the
various props and their normal uses, i.e. climb, “normal,” cruise,
etc.
I just saw this article about HALT testing as it applies to
airplane engines, prop selection and cruise.
In summary, the article suggests running a bit flatter of a
prop, more of a climb prop. Then, in cruise, you let it spin a bit higher
rpm to get your cruise speed and, he asserts, you’ll be putting a lot
less stress on your engine than if you used a “cruise” prop like
the 7152 on a C-85.
Interesting food for discussion. Thoughts, you
experts?
