frameType

A frame is a circumferential stiffener of the fuselage shell: the profile of a structural element swept along a path around the fuselage on its surface. A frame with one position (stringerFramePositionType) is a whole ring: its path is the cross section of the surface in the plane x = <positionX>, starting at the position and running in the direction of increasing <referenceAngle>.

Several positions

A frame with several positions runs on the surface from each position to the next, in the direction of increasing <referenceAngle>, and ends at its last position. The order of the positions therefore decides which way the frame runs: from 255° to 210°, it passes 270°, 0°, 90° and 180°; from 210° to 255°, it covers only the 45° between them. Such a frame can be part of a ring, e.g. a frame interrupted by a door, or a whole ring whose profile changes around the circumference; a whole ring repeats its first position at the end, e.g. at 0°, 90°, 180°, 270° and 360°. Positions with different <positionX> give a frame that is not planar.

Section of the fuselage at x = 8 m seen from behind: rays from the reference point on the axis to the first position at 255 degrees and the last position at 210 degrees, the angle of the first position measured from the z-axis, and the frame running from the first position in the direction of increasing angle over the top to the last position, leaving out the cargo door between them

The figure shows the frame of the example below that is interrupted by the forward cargo door, in the section at x = 8 m seen from behind. It starts at the stringer above the door at 255°, runs over the top, the left side and the bottom, and ends at the stringer below the door at 210°.

Example

The first frame of the barrel shown in fuselageStructureType, a whole ring at x = 7 m starting at the top, and the frame interrupted by the cargo door. Both use a Z-profile that is moved inwards by the height of the stringers, so that the frames stand on the stringers (alignmentStringFrameType).
