The article discusses the peculiarities of spinal fractures in catapulted pilots: mechanism of fracture--indirect axial load in combination with front or front-lateral bending; morphological picture--wedge-shaped compression fracture of vertebral body; type of fracture--stable; clinic peculiarities--scanty clinic picture as a rule; localization--mid-thorax… (More)
The biomechanical characteristics of the middle ear of a live man and a corpse (autopsy material) were compared. The conditions were found that provide the adequacy of biomechanical reactions of both objects to changes in the external air pressure.
To prevention death and serious injuries personnel must be equipped with war materiel collective and individual antimine defence. The experience gained in the establishment of protective equipment shows that modern technology can prevent serious injuries and moderately severe blast injuries in the members of the crew an ensure injury prevention not less… (More)
The authors demonstrate that the training of flight personnel to the ejection from an aircraft in distress is a learning system that includes interconnected types of land-based activities: studying the material part of the means of salvation, documentation, regulatory need for ejection and the ejection rule; exercises in the cockpit; training on special… (More)
The purpose of this work was to evaluate early and delayed effects of static mechanical loading of the spine on human tolerance to the ejection g-loads. Experiments with spine segments showed that static pre-loading equivalent to aerobatic accelerations of 8-10 units leads to relative strengthening of vertebra with low tolerance of the longitudinal shock… (More)
The localization, causes and severity of 214 "ejection-associated" injuries occurred in 160 pilots are discussed. Spine, upper and lower extremities are affected most frequently. The severe injures prevail (57.8%). The main causes of severe injuries are the impact + Gz accelerations of ejection and the impact + Gz accelerations of landing.
According to results of performed examinations scoliotic spinal deformity in flight personnel has a low impact on professional health. This is proved by: oligosymptomatic course of disease - lack of complaints of pain, moderate pain, which is revealed only in case of loading tests and palpation; preservation of supporting and movement spinal function; lack… (More)
The paper considers existing approaches to the classification of outcomes of emergency egress the aircraft. The existing classification of time-related manifestations of the outcome of the bailout supplemented with clause immediate consequences bailout. The analysis of the effects of aircraft emergency escape for the pilot's health, special attention is… (More)
Three groups of criteria can be used to describe ultimate tolerance of the "side-to-side" impact loads by test-subject as a pre-shock or pre-traumatic margin of relatively safe exposure. These groups include subjective signs, regulatory (bradycardia, extrasystole, brief respiratory disturbances) and spinal biomechanics deviations. Physiological experiments… (More)
