One last question on the Concorde...

Recommended Posts

I want to thank all that gave me assistance on setting up my Concorde. I just have one last question about my contact points issue. Here are my current settings, and they produce the sunken-gear issue in the pic below. I just need some help on how to tweak these settings. The rest of the plane in all it's liveries, with the photo-real cockpit and afterburners is working great!!//Tail gear-point.1=1.000, -101.500, 0.000, 0.350, 1042.896, 0.000, 0.600, 0.000, 0.100, 0.500, 0.000, 5.000, 5.000, 0.000, 270.000, 275.000//Mains gear-point.2=1.000, -54.000, -13.000, -13.820, 1580.000, 1.000, 3.236, 0.000, 1.650, 1.550, 1.200, 10.500, 11.500, 2.000, 270.000, 275.000point.3=1.000, -54.000, 13.000, -13.820, 1580.000, 2.000, 3.236, 0.000, 1.650, 1.550, 1.200, 11.000, 12.000, 3.000, 270.000, 275.000

Sorry to take so long - Got work and a life...That's a strange set of gear points. I suspect someone a long time ago adapted it from a tail-dragger. You should pick up the comments (lines with //) from a default plane just so you have the info handy.The parameter of interest is the position of the landing gear relative to the nominal center of the aircraft. The values you've got are 0.350, -13.820 and -13.820 for the 3 gear points. The 0.350 is clearly wrong, but it doesn't seem to be a problem for some reason. That should be the nose gear, but if some other parameter is saying the plane is a tail-dragger that might explain it. These values are all in feet. I note that the point.1 line is also saying the gear is at -101.5 feet, which would put it in the tail as well. Since you don't have a full set of contact points in the post, there may be another one for the nose gear.To get the main gear out of the tar, I'd change the -13.820 to about -15.0 for a test. This should raise the plane a little over a foot. You may also need to play with 2 other values - static_cg_height and static_pitch. static_cg_height defines where the plane will be placed on startup - too high and it will fall to the the ground, too low and it will be stuck in the runway. If you're just a little above the contact points it should settle gently onto its landing gear. Static_pitch controls the angle of the aircraft on startup. Make this value more negative to begin a bit more nose-down. Pitch is in degrees, while static_cg_height is in feet.

The points you have posted are for the Tail and Main gear! You missed out a line :-rollThe nose gear possition is as follows...//Real-world steering angle 60 deg:point.0=1.000, 21.500, 0.000, -13.400, 1242.896, 0.000, 2.636, 50.000, 1.150, 1.700, 0.950, 10.500, 11.000, 0.000, 270.000, 275.000Maybe this might be of some help now?Andrewhttp://ftp.avsim.com/dcforum/User_files/3e37d5c4577a3303.jpg

The Concorde actually does have a tailwheel. It is a very tiny retractable tailwheel at the tailcone used as a bumper should the tail contact the runway surface. Other aircraft such as the Draken and S-2 come to mind as aircraft which also have bumper tailwheels.

Ok, I made the changes to the main gear you guys had suggested, and then copied the nose-gear line directly into my .cfg file. I changed the -13.400 to -14.000, and got this as the total result. It looks 'normal' to me now, with almost no 'dip-bounce' when the plane finishes loading on startup.Scott
