(OP)
A US Navy shrouded propeller's exterior paint scheme includes a 3" red strip at the path of blade rotation. MIL-STD-2161A, PAINT SCHEMES AND EXTERIOR MARKINGS FOR U.S. NAVY AND MARINE CORPS AIRCRAFT lists fuselage painting requirements Para 5.5.5.10.3.6. Is this Mil-Std appropriate for the shroud painting requirement? Is this a safety issue?





RE: A US Navy shrouded propeller's exte
The stripe You noted is generally placed on the exterior of nacelles, cowls or fuselages (or interiors of military acft fuselages with external props). The stripe is in-line with high speed rotating blade systems and demnotes the likely path of fragments, should an uncontained blade failure occur. It is NOT a good place to be [near] during an engine failure, crash, etc... especially for "people", hazzardous materials/cargo [fuel tanks, other flammable/explosive items, etc], or high-value materials.
If there is any tech-data requirement for such a stripe, put it on... it is a safety issue.
