MATLAB在飞行动力学和控制中应用的工具

-----------------------------------------------------------------
AIRDATA2 is a masked Simulink subsystem, used to compute the im-
pact pressure qc, equivalent airspeed Ve, and the calibrated air-
speed Vc. The block AIRDATA2 is contained in the subsystem 'Air-
data Group' of the system BEAVER.

Inputvectors: yatm and yad1 (the inputvariables which are not
used in AIRDATA2 are displayed between accolades).
============================================================
  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)

where:

 {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]

Outputvector: yad2.
===================
  yad2 = [qc Ve Vc]'

where:

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