[Flightgear-devel] CH53e data

[wim v. h. <wim...@gm...>]

Hi there,


Some data for the CH53e yasim model, taken from Prouty [1], p. 699.

Looking at the data in cvs, rotor diameters and chords should/could be
changed, just like control input ranges for the main and tail rotor.

- Fuel capacity (aux):              8450

Engines:
- Type:                         General Electric T64-GE-416
- Number:                    3
- Max T.O. rating:         13140
- Max usable power:     11570

Rotor Parameters:                                  Main                   Tail
- Radius (ft):                                          39.5
         10
- Chord (ft):                                            2.44
          1.28

          0.163
- No. of blades:                                       7
           4
- Tip speed (ft/sec):                                732
        733
- twist (deg):                                         -20
          -8
- equiv. linear hinge offset ration (e/R):   0.063                  0.043
- Airfoil:                                                 SC1095
           NACA 0015
- Collective range (deg):                       -1.4 to 19.6           -10 to 24
- Longitudinal cyclic range (deg):         -8.5 to 18.0             -
- Lateral cyclic range (deg):                 -9.8 to 6.1               -
