|
 | A study was performed using the Air Force Total In-Flight Simulator (TIFS) to gather data concerning spatial orientation, head/neck biodynamics, and the tactile cue environment during certain aircraft maneuvers. The maneuvers included coordinated turns, uncoordinated rolling and pitching motions, roller- coaster motions, lateral accelerations and sustained longitudinal accelerations. Measurements were made of perceived direction of vertical, perceived roll rate (magnitude estimates), and perceived translatory acceleration (magnitude estimates) using a special ... |

 | The physiological effects of accelerated flight are considered to contain perceptual information important to vehicle control and contribute to defining flight envelopes accessible to the pilot. As such, these effects, or acceptable surrogates thereof, must be considered for inclusion within ground- based devices designed to train pilots for their flight mission. This study investigates the physiological effects of accelerated flight within the cardiovascular musculoskeletal, visual, auditory, tactile, and respiratory systems. ... |

|
| Pilots use information from a variety of sensory mechanisms to determine their estimate of orientation and motion. An understanding of this process and a quantitative model are essential for development of effective simulator motion cueing devices. A multisensory model for dynamic spatial orientation is being developed for this purpose. Aircraft or simulator motion is translated into stimuli which are processed by dynamic models of the appropriate sensors (visual, vestibular, tactile, ... |

|
| The purpose of this study was to model human motion and orientation sensing mechanisms so that simulator motion cueing systems can be designed to take full advantage of the characteristics of these sensory mechanisms. Individual models for vestibular, visual, tactile, and proprioceptive sensors have been either adapted from previous modeling work or formulated from available psychophysical and neurophysiological data. A literature search was conducted to help identify material in the ... |

|
| The optimal control model of the pilot has been extended to incorporate motion as well as visual cues so that it can be used to compare fixed-base, moving-base and VFR/IFR differences in simulator systems. The motion cues are included by adding the semi-circular canal and otolith dynamics to the state vector, with the vestibular firing rates available as additional inputs to the kalman filter/predictor. The psycho-physical thresholds are modeled as ... |

|
| The report concerns modern and future fighter aircraft with maneuvering capabilities that now are beginning to exceed the G force limitations of man, particularly with regard to such effects on man's pulmonary, cardiovascular, and labyrinthine systems. Protective mechanisms are discussed that have potential for exceeding man's unprotected tolerance; research at many laboratories is discussed. The report considers that 9 G 30-sec duration acceleration is likely to be tolerable and that ... |

|
| An earlier report described a physical analog of the human vestibular system, which simulated nystagmic eye movements and subjective sensation of motion based on sensed motion of the 'head.' This report reviews a number of possible extensions to this model--emphasizing the complex interactions among visual, otolith, and canal stimuli. Models are discussed for semicircular canals and otoliths, the vestibulo-ocular reflex, optokinetic and galvanic stimulation of eye movements, counterrolling, visual-vestibular interaction ... |

|
| A functional model of the human vestibular system was designed and built. The vestibular model consists of two major subassemblies: a three-axis gimbal system for simulating head motion; and a special-purpose analog computer which permits simulation of the semicircular canal and otolith dynamic response and nonlinearities. The gimbal system head simulator can be driven through the computer or independently. The entire 'head' may be placed in an aircraft or in ... |
