70% to passWhich of the following propulsor types represents the proper terminology for a screw propeller of the conventional design?
AFixed-pitch propeller
BCycloidal propeller
CDetachable-blade (built-up) propeller
DControllable-pitch propeller
AI Explanation
The correct answer is A) Fixed-pitch propeller. A fixed-pitch propeller is the proper terminology for a conventional screw propeller design. This type of propeller has blades that are fixed in place and cannot be adjusted to change the pitch. The fixed-pitch design is the most common and standard type of propeller used on many vessels, including those operated by the US Coast Guard. The other options are not the correct terminology for a conventional screw propeller. Cycloidal propellers, detachable-blade propellers, and controllable-pitch propellers are different types of propulsion systems that are not the same as a fixed-pitch screw propeller.
