"Forward rotor blades" is navy terminology for what???

Jayne Mansfield is sitting in the cockpit of a USN Helicopter Utility Squadron Two (HU-2) tandem rotor Piasecki H-25/HUP Retriever. Photo was taken in 1957.

There are several types of rotor wing aircraft that have a distinct "droop" in the main rotor blades from static and thru start up or wind down at slow slower rpm's as the weight of

the blades has not been overcome by centrifugal force.

Kaman aircraft (HH-43) for example were notorious for low rotor blade tip plane path due to the nature of the design.

The forward cyclic pitch alone (controlled by the pilot) of many helicopter rotor (single) blades will allow the blade tip plane to rotate somewhere around head level for the average height man and is why the industry standard for boarding the aircraft is - walking toward the front of the aircraft so the pilot can see your approach and keep the blade path perpendicular to the rotor mast or high enough to allow safe approach. Twin main rotor aircraft have their own similar rotor plane/path characteristics (and hazards).

Maybe they are also warning of spinning rotor blades attached to her 2 hubs... Kinda figured it must be the H-25 since they mentioned a forward set of blades,
