How is a propeller similar to a wing?
Like a conventional wing a propeller blade will produce a lift and a drag force proportional to the square of the resultant velocity passing over the blade (relative airflow). Whereas a wing’s aerodynamic forces are a function of the forward speed of the aircraft, the propeller’s resultant velocity is a function of both the forward flying ...

Are wooden propellers still used?
On the majority of aircraft, metal and composite props have replaced wood, but, wooden propellers still own 10 percent of the aviation market.
Why are airplane propellers made from wood?
Until the mid-1920s, propellers were made from wood and were fixed pitch, which significantly limited the aircraft's performance capabilities. Wood propellers turned the aircraft engine's power into thrust to propel the plane forward.
How much does a propeller weigh?
Weight varies depending on design; a two-blade propeller weighs between 10 and 14 pounds and a three-blade propeller weighs between 11 and 15 pounds.
What makes a good boat propeller?
As a rule, a stainless-steel prop of the same pitch and diameter will make your boat go faster — up to 2 to 3 knots, on some boats — than an aluminum prop. Stainless steel is stronger and can be made thinner, which allows more speed. Stainless steel also flexes less and keeps its shape at higher speeds.
Are stainless steel props faster?
Performance: If extracting every bit of performance potential from an outboard or sterndrive engine is a priority, go with a stainless steel prop. The thinner blades produce less drag in the water, typically resulting in higher top speeds.
What material are boat propellers made of?
Propellers for commercial boats are typically made from either a stainless steel alloy, a nickel-aluminum-bronze alloy, or a manganese bronze alloy. The costliest material, stainless steel, is very easily repaired and stands up to quite a bit of abuse. The hardest alloy is nickel-aluminum-bronze.

How to make a propeller out of wood?from wikihow.com
Laminate the planks together. You will need to use a very strong glue, like Resorcinol, to create aircraft propellers. Be sure there are no spaces or air between the wood. It may seem easier to use one large piece of wood, but you will have a stronger material by gluing a number of smaller pieces tightly together.
How to secure a propeller?from wikihow.com
Keep the prop stable. You may want to use a vice to secure the propeller while you work. If you don't have one you can tie down one side of the propeller to the table while you work on the other end to keep it secure.
How to check if a propeller is balanced?from wikihow.com
Check the balance on the prop. Put a straight bar through the center hole of the propeller and see if the wings will balance evenly at each end. If the prop stays straight with the blades perfectly horizontal, you have a well-balanced propeller.
Why do propeller blades have a twist?from wikihow.com
A propeller blade is like a wing with a twist. The twist of the blade makes the propeller more efficient at pushing air or water. This is because the speed of the propeller blade is much faster at the tip than at the hub.

How many blades does a propeller have?from wikihow.com
Decide how many blades your propeller will have. Most propellers have two, three, or four blades. Some large aircraft use propellers with even more blades. The more powerful the engine driving the propellers, the more propellers will be needed to distribute the power evenly.
What color should propeller tips be?from wikihow.com
You can also paint the tips a bright color like yellow or red to make the propeller more visible when spinning.
Step 2: Glue Up
The two pieces were glued together using plenty of wood glue and several clamps. When gluing wood, be sure to apply a thin layer of glue to both surfaces to be joined.
Step 4: Drill Center Hole
The propeller spins on a stack of skateboard bearings, mounted on a 5/16" bolt. A hole to house the bearings was drilled using a 7/8" (22mm) forstner bit on a drill press.
Step 5: Band Saw
Tapered lines were drawn onto the wood blank along the sides from the middle section down to 1/2", centered on either end. These wedge shapes were then cut off using a band saw.
Step 7: Mark Areas to Remove on Prop Blades
Areas to be removed on the propeller blades were indicated with a marker.
Step 8: More Band Sawing
The marked areas were carefully nibbled away using the band saw. The blade guide is raised and the blade is used to basically carve the work piece.
Step 9: Progress
Here is the propeller after further roughing out the shape on the band saw.
Step 10: Refine Shape With Belt Sander
The shape of the propeller blade is refined with 36 grit sandpaper on a belt sander. The propeller is held securely in a vise to do this.
How to make a propeller?from wikihow.com
To make a propeller, start by designing the length and number of blades. If you're new to making propellers, you'll want to start with 2 blades since it's easier to construct. As for the length, you can determine the limit by measuring the distance from the nose of your aircraft to the ground since you don't want your propeller to hit the dirt! Once you have a design, begin your build by laminating several planks of wood together since this will make a stronger blade than using 1 thick piece of wood. To learn how to check the balance of your propeller, keep reading!

How to shape an airfoil?from wikihow.com
Shape the airfoil. A propeller blade is thick at the hub with a large blade angle and thin at the tip with a low blade angle. Determine the width of the blade and the angle of attack. Propeller blades are fixed to their hub at an angle, just as the thread on a screw makes an angle to the shaft.
How to make a prop plane?from forum.kerbalspaceprogram.com
However, if you want to make a prop plane or a helicopter, you have to do something about the torque or you'll roll or spin uncontrollably without such control. The usual answer to this is 2 rotors going in opposite directions so the torque cancels out. You can accomplish this in 2 ways. Method 1 is coaxial rotors.

What is RPM on a helicopter?from forum.kerbalspaceprogram.com
For helicopters, generally RPM is constant and torque is mapped to a control axis so can be set at intermediate values depending on need. So you'd have a single button for on/off, then a control axis for the torque. #3 is used for strange contraptions, such as epicyclic amusement park rides :).

Do rotors have an hourglass shape?from forum.kerbalspaceprogram.com
But yeah , the rotor parts have an hourglass shape although 1 end is bigger than the other and has radial attachment nodes (the number of which you can change in the PAW ). The intent is that the smaller end will be rigidly attached to the craft and the big end will spin, with the torque going into the craft's body.
