Panel

class hotwing_core.Panel(left_rib, right_rib, width)

A Panel is a representation of a wing panel and contains all of the items/objects necessary to define a wing.

A Panel can be thought of as a wing facing down with rib_1 on the left and rib_2 on the right. If rib_1 is the root chord and rib_2 is the tip, chord the panel will represent the left part of a wing.

Parameters:

• left_rib (Rib) – Rib defining the left of the wing
• right_rib (Rib) – Rib defining the right of the wing
• width (Float) – Width of the Panel measured from left_rib to right_rib

Variables:

• left_rib – Left Rib
• right_rib – Right Rib
• width – Width

__getitem__(key)

Trim Panel using the slice functionality.

Ex: panel_obj[2:5], trims from 2 to 5

classmethod copy(panel)

Copy a panel

Parameters:panel (Panel) – object to copy Returns:New panel Return type:Panel

get_feedrate_multiplier()

Because the feedrate is always set on the left axis, when we flip a wing around, the feedrate is incorrect. This produces a value between 0 and 1 that is applied to the feedrate to adjust for this.

classmethod reverse(panel)

Reverse the ribs on the panel. If you have a left side, it will make it a right side. The ribs will maintain the same direction, but just switch sides.

Parameters:panel (Panel) – object to flip Returns:New flipped panel Return type:Panel

classmethod trim(panel, left=None, right=None)

Creates a new Panel by taking an existing Panel and trimming it. The new panel’s ribs will be interpolated to the correct shape.

Parameters:

• panel (Panel) – object to trim
• left (Float) – distance from left rib to make the left side cut
• right (Float) – distance from left rib to make the right side cut

Returns:

New trimmed Panel

Return type:

Panel
