Human Training Centrifuge

The Dynamic Flight Simulator (DFS) that is, in fact, one of the crucial functions of the Polish Human Training Centrifuge gives plenty of opportunities for using it in operational, training and diagnostic character. It allows to perform intensive pilot training providing to proper performance of anti-G maneuvers and familiarisation of aircrews with effects of activity of high accelerations with longitudinal time and push-pull phenomena. Moreover the centrifuge provides a safe alternative to raise awareness of aircrews in case of possibilities unwanted effects of accelerations, such as G-LOC loss of consciousness or spatial disorientation. Centrifugal training allows to restore and/or maintain optimal G-tolerance even performing of tasks in the air is impossible or not required. Costs of such training are definitely much lower than possible costs of using modern combat aircrafts and not even mention about human life.

The gondola of the centrifuge has been assembled on eight-meter-long arm and allows to achieve Z-axis accelerations in the range from –3G to +16G with maximal gradient of accelerations increasing to 14,5 G/s. Additionally gyroscopic suspension of the gondola provides to achieve X-axis and Y-axis accelerations respectively in the range of the value ± 10G and ± 6G.

The human centrifuge is dedicated for survey and training of candidates for military pilots and pilots flying on highly-maneuvering aircrafts (i.e. combat, acrobatic and sport), and experimental technical tests.
Interchangeable parts of the centrifuge gondola enable functional projection cockpit equipment of the Polish Air Force basic multi-purpose aircrafts i.e. F-16 Block 52+ and MiG-29.

TRAINING CAPABILITIES

  • pre-startup activities,
  • flights under instruments and navigation (navigation by VOR, VOR/DME, TACAN and NDB, radio procedures – communication equipment maintenance, procedures for flights at night, approach controlled from the Earth, approach to landing by ILS, group flights and navigation in difficult weather conditions),
  • outputting of the aircraft from unusual locations,
  • emergency situations (fire engine, damage of the control system, etc.),
  • combat application (intercept of air targets, defensive maneuvers, use of weapons, etc.),
  • training Spatial Disorientation (SD) consist of:
    • black hole approach,

POSSIBLE TASKS

  • Aircrew pre-selection, evaluation of individual natural G-tolerance,
  • High-G training to recognize individual symptoms of high-G stress and G-tolerance limits,
  • Teaching and training of effective anti-G measures (breathing methods, anti-G straining maneuvers) and the optimal individual use of the G-protection equipment,
  • Improving aircrew tolerance to high-G stress,
  • Improving G-awareness of aircrew,
  • Standardized high-G training of aircrew for high-performance aircraft using pre-programmed standard profiles (STANAG 3827),

  • Equipment testing and assessment of ergonomic aspects of high-G flight.

Moreover possibility of the human centrifuge use for diagnostics allows in comprehensive way to assess the pilot’s physical fitness in environment of real gravitational loads. Possession of the centrifuge with such high parameters will allow to conduct medical research on ways of pilots protection against high and rapidly increasing accelerations. The centrifuge has also large developing potential to conduct additional psychological tests aimed to understand and analyze the pilots behavior subjected the accelerations.
