PSPK-2 Flight Simulator with a Moving Cockpit (four- axis)

Date of Initial Operation: 1976



General Description: The flight simulator PSPK-2 with a moving cockpit is designed to simulate various regimes of flight including critical ones (stall, spin, “Kobra”, etc ) of maneuverable airplanes for the purpose of investigating handling characteristics control systems development and pilot personnel for critical flight regimes.


  • a model of a maneuverable airplane cockpit with electromechanical flight instruments;
  • central control column and pedals with a spring system for load application and trimming mechanisms;
  • a side stick with a spring system for load application;
  • engine control levers.

Visual System (Wide–Angle Projection System):

“Earth-Sky”, consisting of a light point source, a transparency and spherical screen of 10 m in diameter. Images of horizon line, sky and earth surface visible from the altitude of 3-4 kilometres generated on the screen , horizontal and vertical field of view is 180o. Rolling ang heading angles variation is unrestricted; pitch angle variation is from - 45 to + 90 degrees

Cockpit Motion System:

with 4-degrees of freedom and the following displacements:
  • horizontally from - 0.8 to + 0.8 m;
  • roll and pitch angles from - 15 to + 15 degrees; yaw angles from - 10 to + 10 degrees.

Digital Computer Complex:
  • upper level computer;
  • 3 lower level computers;
  • interface device ( 64 channels of Digital-Analogue Transducer and 20 channels of Analogue-Digital Transducer).

Practical Use:

The facility is used to investigate handling characteristics of existing airplanes of various modifications and advanced airplanes.
