Abstract
A fluidfoil (78) for use in guiding fluid-borne vehicles has first and second bodies (82, 80) arranged in telescoping relation and collectively defining the leading and trailing edges (18, 20) of the fluidfoil so that the chord length (24) of the fluidfoil is variable. The bodies (82, 80) are rotatable about a shaft (16) defining an axis (14) in fixed positional relation to the leading edge (18), and the fluidfoil (78) is operable under the influence of a relatively moving, surrounding fluid medium (22) to assume an angle of attack which depends on chord length (24).
