Abstract

A constrained linear spring (20) can increase a spring rate of a linear spring. A constrained linear spring (20) includes a linear spring element (100) having a first end (102) and extends in a first direction to a second end (104), with one or more undulations extending in a second direction transverse to the first direction. The linear spring element (100) has a first spring rate when compressed in the second direction with the first and second ends (102, 104) unconstrained. The constrained linear spring (20) also includes a constraining element (200; 210; 220) dimensioned to contact the first and second ends (102, 104) and at least one undulation of the linear spring element (100) when the linear spring element (100) is uncompressed. The constrained linear spring element (100) of the constrained linear spring (20) has a second spring rate higher than the first spring rate when compressed in the second direction that can be useful to counteract a forward overturning moment (50) in an airfoil (45) of a vane (40).
