PSPK-1 Flight Simulator with a Moving Cockpit (five-axis)

Date of Initial Operation: 1976



General Description:

The flight simulator PSPK-1 with a moving cockpit is designed to simulate various regimes of flight including critical ones (stall, spin, and low speed regimes, etc ) of maneuverable airplanes for the purpose of investigating handling characteristics, control systems development and pilot personnel training 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 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 are generated on the screen, horizontal and vertical field of view is 180 degrees. Rolling and heading angles variation is unrestricted; pitch angle variation is from – 45 to + 90 degrees.

Cockpit Motion System:
with 5 degrees of freedom and the following displacements: 
  • vertical from - 0.5 to + 0.5 m, 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;
  • 2 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.
