The “compressor radius” in aircraft design refers to half the width or size of the compressor’s rotor or impeller. It’s the distance from the center of the rotor to its outer edge. The compressor radius is used to describe the physical dimensions of the compressor and is often employed in geometric calculations.
Mathematically, the relationship between the compressor diameter (D) and the compressor radius (R) is as follows:
- Diameter (D) is the width or size of the compressor’s rotor, measured from one side to the opposite side.
- Radius (R) is half of the diameter, which is the distance from the center of the rotor to its outer edge.
