A numerical technique has been developed a t Langley Research Center which
generates l i n e a r perturbation models from nonlinear a i r c r a f t vehicle simulations.
The technique is very general and can be applied to simulations of any system
tktt is described by nonlinear d i f f e r ~ ~ r t i eaql u ations. The computer program
used to generate these models is discussed with emphasis placed on generation
of the Jacobian matt ices, ca l c u l s t ion o f the c o e f f i c i e n t s needed for solving
the perturbation model, and generation of t h e s o l u t i o n of t h e l i n e a r d i f f e r e n-
t i a l equations. Included in the paper is an example a p p l i c a t i o n of the technique
to a nanlinear model of the NASA Terminal Configured Vehicle
