+Bongodriver Posted September 2, 2007 Posted September 2, 2007 Hi Folks, Me again, new problem, I am modelling a new aircraft, it has canard fore planes, the animations are all great BUT!!! it seems that as the aircraft controls are deflected for up pitch the aircraft actually pitches down, therefore on take off it just buries its nose in the dirt and explodes, I can see no specific entry in an INI file to tell the game that the aircraft has the pitch control at the front of the aircraft and I know of no other aircraft in game to use as reference (looked at the viggen but I didn't see the obvious answer if there is one) Quote
Guest capun Posted September 2, 2007 Posted September 2, 2007 Do you have the ini entry like this? [LeftStabilizer] SystemType=CONTROL_SURFACE InputName=PITCH_CONTROL MovingSurface=TRUE CDdc=0.0018 Cmdc=-0.15536 MaxDeflection=30 MinDeflection=-25 ControlRate=1.0 ModelNodeName=Left_Canard ReverseModelOrientation=True Quote
+Fubar512 Posted September 2, 2007 Posted September 2, 2007 Craig, Canards should be given an aerodynamic surface entry under [AircraftData], like so: [AircraftData] Component[008]=LeftCanard Component[009]=RightCanard They would then require the appropriate entries, as would any lifting surface: [LeftCanard] ParentComponentName=Fuselage ModelNodeName=Line01 DestroyedNodeName= ShowFromCockpit=TRUE DetachWhenDestroyed=TRUE StructuralFactor=1.25 DamageRating=DISABLED MassFraction=0.007 HasAeroCoefficients=TRUE LiftSurface=TRUE CLa=0.261 CD0=0.0004 CDL=0.0012 Cmq=-1.7825 Cmad=-0.8818 Cyb=-0.0109 Clp=-0.0025 Cnb=0.0055 CL0MachTableNumData=5 CL0MachTableDeltaX=0.40 CL0MachTableStartX=0.00 CL0MachTableData=0.986,1.000,1.037,1.020,1.051 CLaMachTableNumData=5 CLaMachTableDeltaX=0.40 CLaMachTableStartX=0.00 CLaMachTableData=1.001,1.000,0.979,0.910,0.938 CD0MachTableNumData=5 CD0MachTableDeltaX=0.40 CD0MachTableStartX=0.00 CD0MachTableData=1.825,1.000,1.028,2.494,2.773 CmqMachTableNumData=5 CmqMachTableDeltaX=0.40 CmqMachTableStartX=0.00 CmqMachTableData=0.971,1.000,1.107,1.261,0.873 ClpAlphaTableNumData=15 ClpAlphaTableDeltaX=4.00 ClpAlphaTableStartX=-28.00 ClpAlphaTableData=1.474,1.361,1.264,1.182,1.115,1.063,1.027,1.006,1.000,1.009,1.034,1.074,1.129,1.200,1.285 XacMachTableNumData=5 XacMachTableDeltaX=0.40 XacMachTableStartX=0.00 XacMachTableData=3.856,3.724,3.585,3.476,3.236 Ymac=-1.19 MovingSurface=TRUE ControlSystemID=1 StructuralFactor=1.00 MinExtentPosition= -1.2907,-1.6681,0.0000 MaxExtentPosition= 1.2907, 1.6681,0.2600 CollisionPoint[001]= CollisionPoint[002]= SystemName[001]=LeftCanard [RightCanard] ParentComponentName=Fuselage ModelNodeName=Line30 DestroyedNodeName= ShowFromCockpit=TRUE DetachWhenDestroyed=TRUE StructuralFactor=1.25 DamageRating=DISABLED MassFraction=0.007 HasAeroCoefficients=TRUE LiftSurface=TRUE CLa=0.261 CD0=0.0004 CDL=0.0012 Cmq=-1.7825 Cmad=-0.8818 Cyb=-0.0109 Clp=-0.0025 Cnb=0.0055 CL0MachTableNumData=5 CL0MachTableDeltaX=0.40 CL0MachTableStartX=0.00 CL0MachTableData=0.986,1.000,1.037,1.020,1.051 CLaMachTableNumData=5 CLaMachTableDeltaX=0.40 CLaMachTableStartX=0.00 CLaMachTableData=1.001,1.000,0.979,0.910,0.938 CD0MachTableNumData=5 CD0MachTableDeltaX=0.40 CD0MachTableStartX=0.00 CD0MachTableData=1.825,1.000,1.028,2.494,2.773 CmqMachTableNumData=5 CmqMachTableDeltaX=0.40 CmqMachTableStartX=0.00 CmqMachTableData=0.971,1.000,1.107,1.261,0.873 ClpAlphaTableNumData=15 ClpAlphaTableDeltaX=4.00 ClpAlphaTableStartX=-28.00 ClpAlphaTableData=1.474,1.361,1.264,1.182,1.115,1.063,1.027,1.006,1.000,1.009,1.034,1.074,1.129,1.200,1.285 XacMachTableNumData=5 XacMachTableDeltaX=0.40 XacMachTableStartX=0.00 XacMachTableData=XacMachTableData=3.856,3.724,3.585,3.476,3.236 Ymac=1.19 MovingSurface=TRUE ControlSystemID=1 StructuralFactor=1.00 MinExtentPosition= MaxExtentPosition= CollisionPoint[001]= CollisionPoint[002]= SystemName[001]=RightCanard Finally, set them up as control surfaces: [LeftCanard] SystemType=CONTROL_SURFACE InputName=PITCH_CONTROL RotationAxis=X-AXIS MovingSurface=TRUE MaxDeflection=-10.0 MinDeflection=3.5 ControlRate=0.5 MaxControlSpeed= 255.0 ModelNodeName=05 [RightCanard] SystemType=CONTROL_SURFACE InputName=PITCH_CONTROL RotationAxis=X-AXIS MovingSurface=TRUE MaxDeflection=-10.0 MinDeflection=3.5 ControlRate=0.5 MaxControlSpeed= 255.0 ModelNodeName=06 ReverseModelOrientation=TRUE These values are from an as yet unreleased model, so you'll want to recalculate for your purposes. The pitch axis I've set here opposes the models elevator pitch, as the real-life aircraft uses an FBW system that pulls the nose down at low speed, high AoA (as would be the case during a carrier landing). If you want the canards to pitch up with the elevators, just add the following line to the last two data fields: ReverseInput=True Quote
