Aeromatic / Jon Berndt / DATCOM / Hal V. Engel 2001-01-01 $Revision: 1.21 $ Advanced model of P-51D fighter (Beta) This model was created using publicly available data, publicly available technical reports, textbooks, and guesses. It contains no proprietary or restricted data. If this model has been validated at all, it would be only to the extent that it seems to "fly right", and that it possibly complies with published, publicly known, performance data (maximum speed, endurance, etc.). Thus, this model is meant for educational and entertainment purposes only. This simulation model is not endorsed by the manufacturer. This model is not to be sold. 235 37.1 1.00 6.6 41 15 20 0 99 0 -26.5 128 0 30 0 0 0 8031 9274 14547 7125 96.5 0 -9 180 98 0 15 0 97 -79.2 -19.2 0 97 79.2 -19.2 0 97 -87.6 -19.2 0 97 87.6 -19.2 0 97 -96 -19.2 0 97 96 -19.2 0 97 87.6 -30 0 97 -87 -30 0 97 87.6 -43 0 97 -87 -43 0 97 87.6 -43 0 97 -87 -43 78 -71 -89.5 0.8 0.5 0.05 9500 2500 6200 0.0 LEFT 1 78 71 -89.5 0.8 0.5 0.05 9500 2500 6200 0.0 RIGHT 1 282 0 -47 0.9 0.7 0.05 4100 4280 STEERABLE -6.0 NONE 1 100 -222 -7 0.80 0.50 11000 1179.23 100 222 -7 0.80 0.50 11000 1179.23 300 0 -25 0.80 0.50 11000 1179.23 300 0 50 0.80 0.50 11000 1179.23 25 0 -30 0.80 0.50 11000 1179.23 15 0 10 0.80 0.50 11000 1179.23 110 0 30 0.80 0.50 11000 1179.23 85 0 -27 0.80 0.50 11000 1179.23 185 0 -45 0.80 0.50 11000 1179.23 10 0 -67.5 0.80 0.50 50 5000 10 0 -67.5 0.80 0.50 50 5000 10 -67.5 0 0.80 0.50 50 5000 10 67.5 0 0.80 0.50 50 5000 36 0 0 -4.0 2.5 -6.0 0 1 2 3 4 36 0 0 -4.0 2.5 -6.0 1 60 110 -80 -9.675 607.21 396 1 110 80 -9.675 607.21 396 0 130 0 -3.0 561 0 0 97,5 -198 -25 495 0 0 97.5 198 -25 495 0 0 fcs/elevator-cmd-norm fcs/pitch-trim-cmd-norm -1 1 fcs/pitch-trim-sum -0.18 0.15 fcs/elevator-pos-rad \ fcs/elevator-pos-rad -0.18 0.15 -1.0 1.0 fcs/elevator-pos-norm fcs/aileron-cmd-norm fcs/roll-trim-cmd-norm -1 1 fcs/roll-trim-sum -0.35 0.35 fcs/left-aileron-pos-rad -fcs/roll-trim-sum -0.35 0.35 fcs/right-aileron-pos-rad fcs/left-aileron-pos-rad -0.35 0.35 -1.0 1.0 fcs/left-aileron-pos-norm fcs/right-aileron-pos-rad -0.35 0.35 -1.0 1.0 fcs/right-aileron-pos-norm fcs/rudder-cmd-norm fcs/yaw-trim-cmd-norm -1 1 fcs/rudder-command-sum -0.35 0.35 fcs/rudder-pos-rad fcs/rudder-pos-rad -0.35 0.35 -1.0 1.0 fcs/rudder-pos-norm fcs/flap-cmd-norm 0 10 20 30 40 47 fcs/flap-pos-deg fcs/flap-pos-deg 0 47 0 1 fcs/flap-pos-norm gear/gear-cmd-norm 0 1 gear/gear-pos-norm /controls/gear/brake-left /controls/gear/brake-parking -1 1 /controls/gear/brake-right /controls/gear/brake-parking -1 1 systems/brakes/brake-left 0.0 0.60 fcs/left-brake-cmd-norm systems/brakes/brake-right 0.0 0.60 fcs/right-brake-cmd-norm Change_in_lift_due_to_ground_effect aero/h_b-mac-ft 0.0000 1.2290 0.1000 1.1240 0.1500 1.1160 0.2000 1.1240 0.3000 1.1050 0.4000 1.0410 0.5000 1.0340 0.6000 1.0190 0.7000 1.0080 0.8000 1.0030 0.9000 1.0010 1.0000 1.0000 1.1000 1.0000
