Fixed pitch Cruise vs Climb prop

Asked by: 579 views , , , ,

How is a cruise prop more effective than a climb prop during cruise? How does taking a "bigger bite" out of the air create more thrust? How does it allow you to fly faster when it is also creating more drag than a climb prop?

    You probably had a multi-speed bike at one time. Remember starting in a lower gear and shifting to a higher one to get more speed once you got going. The pitch of the prop is analogous to the shifting of gears. A climb prop is like the gear you used to start on your way or for going up steep hills. The cruise prop is like the higher gears.

    A constant speed prop is intended to make the airplane perform at its best in various conditions. Of course, the downside is the expense and complexity.
