What a fusedrag can be used for
A fuse drag can be used for a couple of things.
It can be used to make a vehicle more aerodynamic to make the top speed improve.
The fusedrag section can help improve modeling of the aerodynamic drag of a plane.
It can model the fuselage of a plane like a big wing section, with an airfoil.
Example of a symmetrical airfoil is something like NACA0009.afl
Im going to show you improvements a fusedrag can do to a vehicles top speed.
An example im going to use the Dodge Police.
The max speed without wheel spin was about 41 mph.
Now lets add a fusedrag and see what happens.
To add a fuse drag just find two nodes.
Here is what needs to be defined:
- Number of the front-most node of the fuselage: First Node
- Number of the rear-most node of the fuselage: Second Node
- Approximate width of the fuselage: ie: 4.0 (You can use and width you want.)
- Airfoil name: (Default NACA0009.afl)
Here's an example of what i added in the .truck file.
fusedrag 10, 11, 4.0, NACA0009.afl
I got an result, the speed improved by 31mph so if you want more speed add a fusedrag.
I hope this helped you guys out.
