Creation

Description

CompositeCoefficient(valueCell,functionHandle) creates a composite aerodynamic coefficient with a cell array of Simulink.LookupTable objects, scalar numeric values, or Aero.AircraftCompositeCoefficient objects, valueCell, and a specification of how the cell array members are combined, functionHandle.

Input Arguments

valueCell — Collection of Simulink.LookupTable objects, scalar numeric, Aero.AircraftCompositeCoefficient objects

row or column cell array

Collection of Simulink.LookupTable objects, scalar numeric, Aero.AircraftCompositeCoefficient objects, specified a row or column cell array.

functionHandle — Function handle action applied to valueCell cell array members

@prod (default) | @sum

Function handle combination action applied to valueCell cell array members, specified as @prod (product) or @sum (sum).

Examples

Create Aero.Aircraft.CompositeCoefficient for Product of Simulink.LookupTable Objects

Create an Aero.AircraftCompositeCoefficient object of a product of multiple Simulink.LookupTable objects.

Assume a composite coefficient, CL, defined by:

CL=q*S*CLge*CLsb*CLsp*f

where,

• q is the dynamic pressure.

• S is the relevant surface area.

• CLge is the lift Simulink.LookupTable object due to ground effect.

• CLsb is the lift Simulink.LookupTable object due to speed brake.

• CLsp is the lift Simulink.LookupTable due to the spoiler.

• f is the flap position.

To create the Aero.AircraftCompositeCoefficient object as a product of the Simulink.LookupTable objects:

Aero.Aircraft.CompositeCoefficient({CLge,CLsb,CLsp},@prod)
