Abstract
A strut of a magnetostrictive oscillator includes a strut body which includes an airfoil with a first end, a second end, a leading edge, a trailing edge, a first side, and a second side. The strut further includes a heater element within the first side and second side, wherein the heater element connects from the first side to the second side. The strut further includes an electrically insulative layer between the heater element and the strut body. The heater element and the electrically insulative layer are integral with the strut body.
Claims20
A strut of a magnetostrictive oscillating ice detector sensor comprising:
- a strut body comprising:
- an airfoil with a first end opposite a second end, a leading edge extending from the first end to the second end, a trailing edge extending from the first end to the second end and aft of the leading edge, a first side extending from the leading edge to the trailing edge and extending from the first end to the second end, and a second side extending from the leading edge to the trailing edge and extending from the first end to the second end;
- a heater element within the first side and the second side, wherein the heater element connects from the first side to the second side;
- and
- an electrically insulative layer between the heater element and the strut body;
- wherein the heater element and the electrically insulative layer are integral with the strut body.
A method of forming a strut of a magnetostrictive oscillating ice detector sensor, the method comprising:
- depositing an outside layer, comprising:
- depositing a first layer of powder, wherein the first layer of powder is a first material;
- sintering the first layer of powder;
- depositing an insulator layer comprising:
- depositing a second layer of powder on the outside layer, wherein:
- a first portion of the second layer of powder is the first material;
- a second portion of the second layer of powder is a second material;
- a third portion of the second layer of powder is the first material;
- and
- the second portion is between the first portion and the third portion;
- sintering the second layer of powder;
- depositing a heater element layer comprising:
- depositing a third layer of powder on the insulating layer, wherein:
- a first portion of the third layer of powder is the first material;
- a second portion of the third layer of powder is the second material;
- a third portion of the third layer of powder is a third material;
- a fourth portion of the third layer of powder is the second material;
- a fifth portion of the third layer of powder is the first material;
- the second portion is between the first portion and the third portion;
- and
- the fourth portion is between the third portion and the fifth portion;
- sintering the third layer of powder;
- depositing a second insulator layer above the heater element layer by repeating the insulator layer above the heater element layer, thereby forming a continuous conduit of the third material surrounded by the second material;
- and
- depositing a second outside layer above the second insulator layer by repeating the outside layer above the second insulator layer.
An ice detector sensor comprising:
- a mounting base;
- a support strut connected to the mounting base;
- a magnetostrictive oscillator probe head connected to the support strut opposite the mounting base;
- and
- a heater element within the support strut, wherein the heater element is additively manufactured.
