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.
