AIM Inputs

The following list outlines the Missile Datcom inputs along with their default values available through the AIM interface.

• missileDatcom = "misdat"
  File name of missileDATCOM executable
• BODoption = int (1 or 2)
  Generate AXIBOD/ELLBOD Option 1 or Option 2 geometry
• BODtnose = "OGIVE"
  Nose shape:
  "CONICAL" or "CONE" (cone)
  "OGIVE" (tangent ogive) "POWER" (power law) "HAACK" (L-V constrained) "KARMAN" (L-D constrained)
• BODpower = 0
  Exponent, n, for nose power law shape: $(r/R)=(x/L)^n$
• BODbnose = 0
  Nose bluntness radius or radius of truncation
• BODtrunc = False
  Truncation flag: True if nose if truncated, False is nose is not truncated
• BODtaft = "CONICAL"
  Afterbody shape:
  "CONICAL" or "CONE" (cone)
  "OGIVE" (tangent ogive)
• FinSet = NULL
  Tuple used to input FinSet information, see Missile DATCOM FinSet for additional details.
• Mach = double
  OR
• Mach = [double, ... , double]
  Mach number.
• Ren = double
  OR
• Ren = [double, ... , double]
  Reynolds numbers per unit length
• Vinf = double
  OR
• Vinf = [double, ... , double]
  Freestream velocities
• Tinf = double
  OR
• Tinf = [double, ... , double]
  Freestream static temperatures
• Pinf = double
  OR
• Pinf = [double, ... , double]
  Freestream static pressures

  OR

• Alpha = [double, ... , double]
  

  Angle of attack [degree].

• Beta = 0.0
  Sideslip angle [degree].
• Altitude = double
  OR
• Altitude = [double, ... , double]
  Flight altitude.
• BL_Type = "TURB"
  Boundary layer type: "TURB" for fully turbulent and "NATURAL" for natural transition
• Surface_Roughness = None
  Surface roughness height. Only use one of "Surface_Roughness" (will take precedence) or "Roughness_Rating".
• Roughness_Rating = None
  Roughness height rating. Only use one of "Surface_Roughness" (will take precedence) or "Roughness_Rating".

Note: Any of the following combinations satisfy the minimum requirements for calculating atmospheric conditions (Mach and Reynolds number):

1. MACH and REN
   
2. MACH and ALT
   
3. MACH and TINF and PINF
   
4. VINF and ALT
   
5. VINF and TINF and PINF
   
6. VINF and TINF and REN
