Simulator for Air-to-Air Combat Motion System Investigation.
Abstract
This investigation was conducted to evaluate the Simulator for Air-to-Air Combat (SAAC) motion system response to known input signals, to observe platform movements, to measure leg extension velocities and accelerations, and to establish delay lags through the system electronics and hydraulics. Signal voltages at pre-established levels were input by a signal generator at the analog-to-digital converter simulating pilot's control stick movements. Resulting platform movement was recorded on strip chart recorder measuring accelerations and final positioning from six linear and angular accelerometers mounted beneath the motion platform. Several noticeable factors were revealed that contribute to the status of the motion platform being less than representative of motion of the aircraft. First, the motion platform lags the input command by a noticeable amount. The platform's motion is about a multiple set of axes rather than a single axis as the command would direct. Also, because of physical constraints on the size of the system, the magnitude and deviation of the motion are limited. A fourth major problem is that when the excursion is near the maximum allowable, the motion is stopped too abruptly, and this stopping is readily perceived by the pilot (the washout problem).
