Abstract
A flow body for an aircraft is disclosed having a stiffening structure and a flow surface at least partially enclosing the stiffening structure, the flow surface having a leading edge and a trailing edge at a distance to each other in a chordwise direction, the flow body including a first heating device attached to or integrated into the flow surface in a first chordwise section, a second heating device attached to or integrated into the surface body in a second chordwise section. The first chordwise section and the second chordwise section are distanced from each other, the first chordwise section is closer to the leading edge than the second chordwise section, and at least the second heating device comprises an electric heater.
Claims14
A flow body for an aircraft, comprising a stiffening structure and a flow surface at least partially enclosing the stiffening structure, the flow surface having a leading edge and a trailing edge at a distance to each other in a chordwise direction, and a solid trailing edge element, the flow body further comprising:
- a first heating device attached to or integrated into the flow surface in a first chordwise section,
- a second heating device attached to or integrated into the flow surface in a second chordwise section,
- wherein the first chordwise section and the second chordwise section are distanced from each other,
- wherein the first chordwise section is closer to the leading edge than the second chordwise section,
- wherein at least the second heating device comprises an electric heater, and
- wherein the second heating device extends to a position directly in front of the solid trailing edge element.
A method of heating a flow surface of a flow body for an aircraft for preventing or removing ice accumulation, wherein the flow body comprises a solid trailing edge element, the method comprising:
- heating a first heating device attached to or integrated into the flow surface in a first chordwise section,
- heating a second heating device attached to or integrated into the flow surface in a second chordwise section,
- wherein the first chordwise section and the second chordwise section are distanced from each other,
- wherein the first chordwise section is closer to the leading edge than the second chordwise section,
- wherein at least heating the second heating device comprises delivering an electric current to an electric heater comprised in the second heating device, and
- wherein the second heating device extends to a position directly in front of the solid trailing edge element.
