Record 1 1990-11-20

English

Subject field(s)
  • Cooling and Ventilating Systems
CONT

The blade may be forward-curved, radial, or backwardly inclined. Vector diagrams of the velocity at the blade tip show that the air leaves the backwardly inclined blade at lower velocity than the tangential velocity of the wheel.

CONT

Backward curved blades ... are constant thickness airfoil blades and are preferred over straight backward inclined blades ... because they allow smoother air flow and are stronger.

OBS

"Backward curved blade" and "backward inclined blade" are usually synonyms, but some sources make a distinction between those two terms. In the "backward curved blade", the blade is curved, and in the "backward inclined blade", the blade is straight.
