📚noun

aerofoil

🗣️

DEFINITION

curved structure designed to give lift, wing surface, blade section

EXAMPLE SENTENCES

Engineers designed the aerofoil to produce maximum upward lift while minimizing turbulent atmospheric drag forces. The shape of an aerofoil causes air to move faster over its upper surface than beneath it. Testing different aerofoil designs in wind tunnels helps aerospace scientists improve fuel efficiency in modern planes. Damage to the aerofoil section can severely impair an aircraft ability to maintain stable level flight. The helicopter rotor blades function as a rotating aerofoil to lift the heavy vehicle straight upward.
