The “1147 HD ABS Black Propellers 1CW+1CCW (1 Pair)” appears to be a set of propellers designed for use with drones or quadcopters. The “1147” in the name likely indicates the size of the propellers, where the first number (11) represents the length in inches, and the second number (47) signifies the pitch in inches. The “HD” could imply that these propellers are designed for high-definition (HD) drones, although it’s always a good idea to check the manufacturer’s specifications for precise details.

The Propellers 1147(11X4.7) ABS Black is the high-quality propellers specially designed for multi-copters.
These Propellers are light in weight and high strength propeller has a 15° angle design at the end of the propeller to avoid whirlpool while the multi-copter is flying. They are useful in drones as well as in multi-copters.
The propellers help to improve the air-powered efficiency and aerofoil stability

Features:
