Micro Flight supports several types of vehicles, the following sections show the detailes of the various formats of
these vehicles and gives instructions for creating them.
All of these vehicles have intrument panels which share the
same format and are documented in the following sections.
The foot launched
gliders are built in the format of HangSim gliders, they are based
upon a chracter animation for the pilot which is used in
chase view, and a static wing model that is used in pilot
view.
The
aircraft directory inside the MicroFlight directory
containes the available gliders, each glider is placed
inside a directory inside the MicroFlight\aircraft directory.
Inside
each glider directory are the following files:
Glider.cfg
This file containes the aerodynamic characteristecs of the glider
and a short description for it.
The structure of
the Glider.cfg file is as follows:
----------------------------------------
0
30.0
16.0
0.05
0.025
120.0
3.5
0.3
0.0
0.15
1.0
650.0
6.0
6.0
3.0
0.0
----------------------------------------@
Low preformance Trainer.
High wing area, low speed , low glide ratio.
breaks easily , Unpowered .
Excells in slow speed , good for rigde flights.
Poor penetration against head winds.

Explanation:
This file is composed of two sections:
1.the glider data:
HasEngine; // does the glider
have engine 0 or 1
VNE = 30; // never exceed speed
s = 16.0; // m^2
cd0 = 0.05; // unitless
ki = 0.025; // unitless
float m = 120.0; // kg
cla = 3.5; // unitless
al_max = 0.3; // radians
al_min = 0.0; // radians
alfa0 = 0.15; // radians
th_factor = 1.0; // thrust efficiency
th_static = 650; // static thrust newtons
g_max = 6; // max g
sink_max = 6; // max sink rate on ground
thermal_sense = 3; // thermal sensitivity factor
glider type = 0; // 0 - hang glider 1 -
convetional 2 - paraglider
2. The glider description :
this part is a simple text only
section that must begin with @ and endes when the
file ends.
Wing_0.x
This is the main model file for the glider without the pilot,
this model file will be used only from the pilot's view.
This
is a simple one frame
hirarchy mesh file, it can be created by converting a 3DS file into an X file by using the command "conv3ds
-m [filename.3ds]" , conv3ds.exe is a
small freeware converter written by Microsoft.
Wing_fa.x
This is an animated mesh file which includes the glider
and the pilot, this model file will be used only for the
chase and leave view.
This
file can be created by converting a 3DS file into an X file by using the command "conv3ds
-A [filename.3ds]" , conv3ds.exe is a
small freeware converter written by Microsoft.
The animation
containes 120 frames with the following keys:
0 - pilot is standing
0 - 30 - pilot is running
30 - 60 - transition phase
60 - 70 speed effects
70 - 80 transition phase
80 - 100 breaking phase
100 - 120 pilot's behaviour
while glider broken.
Wing_fb.x
This is the simple model file for the glider as a traffic object
, this model file will be used only for traffic items of
this glider only.
This
is a simple one frame
hirarchy mesh file, it can be created by converting a 3DS file into an X file by using the command "conv3ds
-m [filename.3ds]" , conv3ds.exe is a
small freeware converter written by Microsoft.
The X
files may contain any number of textures, the format of
these textures must be a BMP file ( 256 colors or better
) and it must be rectangular with size of 16x16 to
256x256 pixels.
All
these textures will be placed into the glider directory
so the program can find it when loading a glider.
