I am interested in developing a flight model in jbsim. jbsim requires a thrust table similar to as follows, with varying mach and altitude numbers (with thrust as a fraction of max):
| -10000 0 10000 20000 30000 40000 50000
-----+--------------------------------------------------------
0.0 | 1.2600 1.0000 0.7400 0.5340 0.3720 0.2410 0.1490
0.2 | 1.1710 0.9340 0.6970 0.5060 0.3550 0.2310 0.1430
0.4 | 1.1500 0.9210 0.6920 0.5060 0.3570 0.2330 0.1450
0.6 | 1.1810 0.9510 0.7210 0.5320 0.3780 0.2480 0.1540
0.8 | 1.2580 1.0200 0.7820 0.5820 0.4170 0.2750 0.1700
1.0 | 1.3690 1.1200 0.8710 0.6510 0.4750 0.3150 0.1950
1.2 | 1.4850 1.2300 0.9750 0.7440 0.5450 0.3640 0.2250
1.4 | 1.5941 1.3400 1.0860 0.8450 0.6280 0.4240 0.2630
Given that I know the thrust of an engine at sea level, in a standard atmosphere at 0 velocity, how would one calculate, or extrapolate the same data for something such as a J57-21?
