Abstract
An engine component for a turbine engine, the engine component comprising a wall bounding an interior; a panel portion defining a portion of the wall, the panel portion comprising: an outer wall; an inner wall spaced from the outer wall to define a wall gap; and a structural segment formed within the wall gap comprising at least one structural element. The apparatus formed from a method including calculating a factor and adjusting a variable until the factor is between a given range.

An engine component for a turbine engine, the engine component comprising:
- a wall comprising an inner wall and an outer wall spaced from the inner wall to define a wall gap and bounding an interior;
- a structural segment defining a portion of the wall, the structural segment comprising at least one structural element disposed between the inner wall and the outer wall at an orientation defined by a structural element angle;
- and
- wherein a frequency factor, determined from a modulus, an area, and a moment of inertia, each associated with the structural segment, is between 1 and 1.4.
A blade for a turbine engine, the blade comprising:
- a wall having an inner wall and an outer wall spaced from the inner wall to define a wall gap and at least one structural element disposed between the inner wall and the outer wall at an orientation defined by a structural element angle;
- the wall having a modulus (E′), an area (A′), and a moment of inertia (I′);
- and
- wherein the blade has a frequency factor

- determined from the modulus, the area, and the moment of inertia, and wherein the frequency factor is between 1 and 1.4.
A test blade for a turbine engine, the test blade comprising:
- an outer wall, an inner wall spaced from the outer wall to define a wall gap, and a structural element disposed within the wall gap at an orientation defined by a structural element angle determining a frequency factor associated with the test blade;
- and
- wherein the test blade has a frequency factor of between 1 and 1.4 where a frequency factor equal to 1 is associated with a solid wall having no wall gap and a frequency factor equal to 1.4 is associated with a wall gap with no structural elements.
