Compute aerodynamic forces and moments using Digital DATCOM static and dynamic stability derivatives
Aerospace Blockset / Aerodynamics
The Digital DATCOM Forces and Moments block computes the aerodynamic forces and moments about the center of gravity using aerodynamic coefficients from Digital DATCOM.
The Digital DATCOM Forces and Moments block port labels change based on the input and output units selected from the Units list.
The Digital DATCOM Forces and Moments block supports only Digital DATCOM, which is the 1976 version of DATCOM.
The operational limitations of Digital DATCOM apply to the data contained in the Digital DATCOM structure parameter. For more information on Digital DATCOM limitations, see Section 2.4.5 of reference [1].
The Digital DATCOM structure parameters
alpha
, mach
, alt
,
grndht
, and delta
must be strictly
monotonically increasing to be used with the Digital DATCOM Forces and Moments
block.
The Digital DATCOM structure coefficients must correspond
to the dimensions of the breakpoints (alpha
,
mach
, alt
, grndht
,
and delta
) to be used with the Digital DATCOM Forces and
Moments block.
