Final answer:
Option (C), The maximum gap between the Venturi Ejector Nozzle and turkey feathers in aerospace engineering components is 15 inches.
Step-by-step explanation:
The maximum gap between the VEN (Venturi Ejector Nozzle) and turkey feathers design components in aerospace engineering is 15 inches. This measurement is based on a newer approach that expands on an older rule of thumb. While the older guideline recommended a spacing of 5 inches side-to-side and 7-8 inches deep, recent studies suggest a much larger gap can be tolerated.
Newer work advises that up to 8 diameters side-to-side and 15 diameters deep can be considered safe and functional. This ensures a successful balance between structural integrity and aerodynamic efficiency in the design and functioning of aerospace components.
