Under the Earth conditions you can "execute" a short-term space flight according to the following cyclogram:
"Soyuz" space vehicle insertion into the Earth artificial satellite orbit with full or reduced/shortened in time G-load (up to 4 G, duration up to 540 sec);
Short (60 minutes-long) orbital flight, during which you can verify you adaptation possibilities to weightlessness;
"Soyuz" space vehicle de-orbiting from the Earth artificial satellite orbit with full or reduced/shortened in time G-load (up to the moment of parachute deployment, 6.5 G, duration to 420 sec).
In addition, you can experience a long-term G-load of a desirable value and direction, including simulation of the typical test profiles for fighter - pilots and cosmonauts. You can order testing of different systems (devices) for their reliability and work capacity under G-load conditions.

At insertion and de-orbiting stage the spacecraft is exposed to G-loads. Under conditions of the Earth gravitation we are using the method of semi-natural simulation of linear accelerations in the centrifuges with a mobile cab for simulation of G-loads, originating in a space flight. The mobile cab can have different degrees of freedom. The cab rotation can be controllable by means of controls and uncontrollable, using the inertia force effect on the offset center of gravity.
The major factor of the orbital flight, affecting a cosmonaut, is a weightlessness state, which causes essential changes in cardiovascular and vestibular systems operation. Sensory and vegetal disorders, occurring in the first hours and days of cosmonauts stay in orbit, are called " satellite disease " or "space motion sickness ". The three-degree gimbaled centrifuge is able to simulate a "physiological weightlessness". Its sense is to initiate disorders of cosmonauts' vestibular system, by controlling the centrifuge motion and angular attitudes of its cab according to the special law, which causes the simultaneous re-distribution of fluids in the cosmonauts' organism by creating the excessive pressure in the lower part of the space suit.
