Subsystem Airdata2

Airdata2 computes the impact pressure qc, equivalent airspeed Ve, and the calibrated airspeed Vc. The block Airdata2 is contained in the subsystem Airdata Group of the Beaver model. Other airdata (-related) variables are computed in the blocks Atmosph, Airdata1, and Airdata3, which also contained in the subsystem Airdata Group.

Inputvectors: yatm and yad1

  yatm = [rho ps T mu g]'   (atmospheric properties, computed in
                                               the block Atmosph)
  yad1 = [a M qdyn]',      (speed of sound, Mach number, dynamic
                        pressure, computed in the block Airdata1)

 {rho  : airdensity [kg/m^3]                                    }
  ps   : static pressure [N/m^2]
 {T    : temperature [K]                                        }
 {mu   : dynamic viscosity [kg/(m*s)]                           }
 {g    : acceleration of gravity [m/s^2]                        }

 {a    : speed of sound [m/s]                                   }
  M    : Mach number [-]
  qdyn : dynamic pressure [N/m^2]

The inputvariables which are not actually used by Airdata2 have been displayed between curly braces.

Outputvector: yad2

  yad2 = [qc Ve Vc]'

  qc   : impact pressure [N/m^2]
  Ve   : equivalent airspeed [m/s]
  Vc   : calibrated airspeed [m/s]
