A real-time airframe simulation was constructed with an all analog, hybrid-single Central Processing Unit (ePU), hybrid-dual CPUs with shared common memory, hybrid-dual CPUs with an Input/Output serial link, and all digital computer configurations so as to investigate the effects of various computer error sources on solution accuracy. The air-frame simulation represented three degrees-of-freedom of longitudinal motion such that effects of error sources on both short period and phugoid motion could be observed. The error analysis utilized Fast Fourier Transforms which showed how the Power Spectra of the transient airframe response distorted (relative to a theoretical response) when contaminated with error sources.
