MORPHING AEROFOIL

摘要

A morphing aerofoil comprising: a leading edge; a trailing edge; and upper and lower surfaces extending between the leading and trailing edges. An upper thermal actuation member is provided proximate the upper surface; and a lower thermal actuation member is provided proximate the lower surface opposite the upper thermal actuator. The upper and lower thermal actuation members have different thermal expansion coefficients and are positioned such that they cause the trailing edge to deflect when they expand or contract by different amounts in response to a change in ambient temperature, thereby changing a camber of the aerofoil.

1. A morphing aerofoil comprising: a leading edge; a trailing edge; upper and lower surfaces extending between the leading and trailing edges; an upper thermal actuation member proximate the upper surface; and a lower thermal actuation member proximate the lower surface opposite the upper thermal actuator, wherein the upper and lower thermal actuation members have different thermal expansion coefficients and are positioned such that they cause the trailing edge to deflect when they expand or contract by different amounts in response to a change in ambient temperature, thereby changing a camber of the aerofoil.
