FA2 Collects aeroelastic flutter data
FA2
Collects aeroelastic flutter data
Collects aeroelastic flutter data for reduction and presentation for each loop through
the configuration parameters.
Format:
FA2 CPH1,CLAMA1,FSAVE/
CPH2,CLAMA2,CASEYY,OVG/
S,N,TSTART/VREF/AECONFIG/SYMXY/SYMXY/LPRINT $
Input Data Blocks:
CPH1 Complex eigenvector matrix for h-set in flutter analysis.
CLAMA1 Complex eigenvalue summary table in flutter analysis.
FSAVE Flutter storage save table
Output Data Blocks:
CPH2 Appended complex eigenvector matrix for h-set in flutter analysis.
CLAMA2 Appended complex eigenvalue summary table in flutter analysis.
CASEYY Appended Case Control table in flutter analysis.
OVG Table of aeroelastic x-y plot data for V-g or V-f curves
Parameters:
TSTART Input/output-integer-no default. On input, TSTART is the CPU clock
time at entry to FA1. On output, set to -1 if there is insufficient time for
another DMAP loop.
VREF Input-real-no default. Flutter velocity divisor to obtain flutter indices.
AECONFIG Input-character-no default. Aerodynamic configuration.
SYMXZ Input-integer-no default. Aerodynamic z-y symmetry flag.
SYMXY Input-integer-no default. Aerodynamic x-y symmetry flag.
LPRINT Input-logical-default=TRUE. Print flag for flutter analysis.
Remarks:
All output data blocks are must be declared on the FILE statement with APPEND
keyword in order to append outputs from previous loops.
