blade loading

blade loading

[′blād ‚lōd·iŋ]
(aerospace engineering)
A rotor's thrust in a rotary-wing aircraft divided by the total area of the rotor blades.

blade loading

The ratio of the all-up weight of a helicopter to the total area of a rotor, excluding the disc area. It is the amount of the total weight each square foot of a helicopter rotor blade supports. Since blade area does not change, blade loading must be a constant in flight. Also called disc loading .
