Other Available Tabs
This tab is used to define items of an aircraft for which the drag will be calculated to determine aircraft performance. These items have been predefined in the system parameters setup and may be altered for any design configuration. Please note that modification of these items for an aircraft configuration is only possible in the registered version of Winfoil.
The available aircraft configurations are;
Monoplane
Biplane
Canard
Flying Wing
Tandem Wing
The following information is displayed for each item;
|
Item Name |
eg; Wing |
|
Description |
This is a comment on what type of area is needed for the drag calculation. This varies according to the item and the available drag coefficients. For example; |
|
|
Wing Wing Area |
|
|
Wheel Frontal Area |
|
Cd |
Drag Coefficient. This can either be automatically obtained from data stored in Winfoil or entered manually. |
|
Area |
This is the area used to calculate drag for the item. This is calculated in the units which are selected at the bottom of the Tab. All areas use the same units of measurement. |
|
Flat Plate Area |
This is the calculated drag of an item. |
|
|
Flat Plate Area = Cd (Drag Coefficient) X Area |
At the bottom of the tab the total Flat Plate Area is displayed. This is a summation of the flat plate area for each item. This value will be used to calculate the performance of an aircraft.
The two buttons provided on this tab are;
|
Change |
Used to change the currently selected drag items area, drag coefficient and if a Wing, the aspect ratio. Click on this button to open the Edit Drag Breakdown Item screen. You may also access this screen by double clicking on a drag item. |
|
Default |
This button is used to reset the drag items. This button will clear the drag items and recreate them based on the definitions for the aircraft configuration. This button is useful if the items have been changed. |
The Units dropdown list at the bottom of the screen is used to set the units of measurement used for the area for each drag item. The units selected in this screen do not have to match the units used in other tabs. Winfoil will automatically convert the units between tabs.
