This report describes a program which was conducted to develop improved testing methods for helicopter fire control acceptance testing by providing meaningful simulation of angular motions within the laboratory. Tests were conducted on a Flight Motion Simulator (FMS), which is hydraulically actuated, operable in both manual and tape modes, and constructed to handle individual test specimens no larger than twenty inches in diameter. Using a pre-recorded tape of angular motion measurements were made in the AH-1G 'Cobra' helicopter. Data was obtained of the machine's operation in both the tape and manual operating modes. The data indicates that it is possible to simulate helicopter motion (of up to 50 Hertz) on the table of the FMS by playing a pre-recorded tape of helicopter motion through the FMS's tape input. It is also possible to reproduce manually the displacement and acceleration curves of motions (limited by frequencies up to 50 Hertz) that are presently specified for helicopter mounted instrumentation.
