Airplane Propeller Prop
in aviation(private) what determines prop #'s?
I'm sure this is obvious to any aviation buff:
what factor limits the # of blades on the prop of an airplane engine
jet engines must have 100's of tiny blades in them
is there a limit to the # of propellers an airplane engine can have
I ask this question peering through the pinhole of how much mire efficient five bladed ceiling. cooling fans are than their 3 & 4 bladed
predicesors. Why couldn't a ten blade engine out run a 4 blade?
There are many aerodynamic factors to consider but in the real world the practical considerations are probably the most concern. The best propeller (efficiency) is a single blade with a counterweight for balance. A few aircraft have actually been built with this arrangement. For most real aircraft the single blade would have to be very long and you have other limitations - ground clearance and keeping the blade tips sub-sonic. Most light aircraft have used 2 bladed props because they are the best compromise between performance and complexity (cost). Their has been a trend the past several years for 3 and 4 bladed on light aircraft. This is due to noise pollution concerns. More blades = shorter blades = less noise. Listen to a twin Beech with 2 bladed Hamilton Standard props take off and then listen to one with Hartzel 3 bladers and you'll understand about noise. The biggest factor in large aircraft has always been ground clearance. Noise wasn't a big deal when they were making prop driven airliners.

Manually starting Airplane Propeller?
it's been a long time since I've flown but and I've looked in my old manuals to find nothing on the procedure for manually starting a single prop plane.... where do you stand? I believe it makes sense to stand behind it on the right side but for some reason I remember my instructor standing in front of the prop when teaching me this very dangerous procedure. Any pilots?
Lot's of good advice so far but different a/c types require a different approach to hand starting techniques.
Go and find a flight training instructor who regularly hand starts aircraft as part of his job and let him teach you the safe methods.
I've started many a/c types by hand over the last 30 years and I'm still learning, so never assume even when taught the correct method of hand starting that you know how to do it safely.
I almost lost a thumb once and I thought I'd done everything correctly.
Here's some tips from what I've learnt in three decades.
No loose clothing. Keep jackets zipped/buttoned up.
Good firm dry ground to stand on.
Never, never risk wrapping your fingers around the trailing edge of the prop to give you a better grip. Use the flat of your hand to pull the prop through.
Pull the prop through in a way that when your hands come away from the prop, the momentum of your body is taking you away from the prop.
If you must use gloves (to improve grip) use thin gloves.
If hand starting a taildragger, tie the tail down as well as chocking the main wheels.
No matter how well maintained an a/c may be, always regard the prop as live. You never know when a magneto earthing wire will break.
Don't ever be tempted to advance the ignition timing beyond the recommended point. You'll loose a hand, finger or thumb at the very least when the engine kicks back and the prop catches your hand with the trailing edge. I was lucky. The only thing that got badly damaged was the trailing edge of a wooden prop. My thumb trebled in size within 5 minutes but thankfully severe bruising was all it sustained.
Last thing, unless you are extremely confident and experienced, never attempt to handstart an a/c fitted with a starter that has failed. The prop will not be in the best position for hand starting when puling through TDC and falling into the prop is a sure thing if you don't know what you're doing.
Good luck.
