Propeller - 14 CFR 1.1
Propeller means a device for propelling an aircraft that has blades on an engine-driven shaft and that, when rotated, produces by its action on the air, a thrust approximately perpendicular to its plane of rotation.
Propellers may be classified as to whether the blade pitch is fixed or variable. The demands on the propeller differ according to circumstances. For example, in takeoffs and climbs more power is needed, and this can best be provided by low pitch.
Propeller de-icing
Only a small section of the blades are heated or treated with fluid. Ice forms on the inner sections of the blades as the angular speed at that point is lower than at the tips, where ice can not attached easily.

Grab the propeller by hooking your index and ring fingers around either side of the center, straddling the motor between them. Hold the airplane's body with the other hand, and grip it by something sturdy like the cockpit -- not the tail!

Contra-rotating propellers have been found to be between 6% and 16% more efficient than normal propellers[1]. However they can be very noisy, with increases in noise in the axial (forward and aft) direction of up to 30 db, and tangentially 10db[1].
propeller - A device on an aircraft, consisting typically of two or more blades twisted to describe a helical path as they rotate with the hub in which they are mounted, and serving to propel the aircraft by the backward thrust of air.

Propellers For the forty years following the Wright Brothers first flight, aircraft used propellers to produce thrust. Modern general aviation aircraft still use propellers.
PROPELLER SPEED REDUCTION UNIT (PSRU) - A gearbox or a belt and pulley device used to reduce the output rotational speed (rpm) when compared to the higher input rpm of the powerplant.
Propeller: A device commonly used to convert the power of an aircraft piston or turboprop engine into propulsive force; each blade is essentially a rotating wing, twisted and varying in section from root to tip to achieve maximum efficiency, ...
geared propeller - A propeller driven from the crankshaft through a series of reduction gears. This allows the engine to operate at an efficient speed while holding the propeller RPM in its efficient range.
Propeller Pitch.-Pitch is best defined by analogy to an ordinary wood-screw; if the screw is turned one revolution it advances into the wood by an amount equal to its pitch.
PROPELLER - Rotating blades of aerofoil section, engine driven, each of which reacts as an aircraft's wing, generating low-pressure in front and higher behind, thus pulling the aircraft forward.

When the propeller disk is inclined to the direction of flight (so that P-factor really is occurring) the downgoing blade has a slightly greater angle of attack (compared to the upgoing blade) as shown in figure 8.4.
FEATHERED PROPELLER- A propeller whose blades have been rotated so that the leading and trailing edges are nearly parallel with the aircraft flight path to stop or minimize drag and engine rotation.
A two-bladed propeller driven by a steam engine pulled the machine around the track. The Phillips Flying Machine of 1893 was able to lift its own weight plus 72 pounds (a total of 402 pounds) some three feet, at a speed of about 40 m.p.h.

feather (of a propeller) - to set the angle of CS or VP propeller edge on to the airflow to minimise drag and rotation following engine failure on multi engined aircraft.
PUSHER - A propeller mounted in back of its engine, pushing an aircraft through the air, as opposed to a TRACTOR configuration.
QUADRAPLANE, QUADRUPLANE - An aircraft having four or more wingforms.
Inspection of Propeller. The first point that should receive attention is the propeller. It should be carefully examined to determine that the blades are in good condition.
The propeller is just a big fan in the front of the plane to keep the pilot cool. Want proof? Make it stop; then watch the pilot break out into a sweat.
Constant Speed Propeller - A propeller that relies upon a governor mechanism to adjust the blade pitch to maintain a constant engine speed during all phases of flight.
(Boating) To accommodate a midship engine location in a small boat, and still maintain a modest 12 degree angle, the propeller shaft must pass beneath the crankcase. This results in positioning the engine so that the transmission faces forward, ...
Slow the airplane down (in the case of propeller-driven aircraft, to something between 60-80 knots). It is far easier to land a slow airplane than a fast one.
Give yourself some distance.
The helicopter is type of aircraft in which lift is obtained by means of one or more power-driven horizontal propellers called rotors. When the rotor of a helicopter turns it produces reaction torque which tends to make the craft spin also.
New propeller airfoil, giving improved speed and climb capability.
1965. Standard bench seat replaced with bucket seats.
1966. Vertical stabilizer gets swept back 35 degrees, decreasing rudder authority slightly.
The driven region, also called the propeller region, is nearest to the blade tips and normally consists of about 30 percent of the radius. The total aerodynamic force in this region is inclined slightly behind the rotating axis.
Autogyros can be of tractor configuration (with the engine(s) and propeller(s) at the front of the fuselage), e.g., Cierva, or pusher configuration (with the engine(s) and propeller(s) at the rear of the fuselage), e.g., Bensen.
A propjets turboprop engine is an aircraft power plant that uses gas turbines to drive a propeller. The turbine is specifically for this so almost all of its output gets used to drive the propeller.
Unlike the Seneca and Seminole that employ counter-rotating propellers, the DA42 turns both engines left, so the left mill is critical. In other words, you'll generate more of a rolling moment if the left engine fails than if the right quits.

It uses a jet engine to turn a propeller. Thrust is generated by both the propeller and the exhaust gases of the jet itself. Turboprops are used on small, short-range aircraft such as those often operated by commuter and regional airlines.
