CENTRIFUGES

CENTRIFUGES

Centrifuge TsF-7
TsF-7 dynamic trainer-centrifuge was opened on March 1973.
The centrifuge is intended to perform the following functions:

check g-load tolerance while cosmonauts and pilots selecting;

improve medical-biological g-load tolerance and enhance operator’s skills while cosmonaut training;

study the extreme flight factors affecting person and onboard systems;

conduct medical researches in order to practice methodic of improving g-load resistance, reducing its unfavorable affect and predicting of a person’s g-load resistance;

perform experimental researches on increasing cosmonaut training efficiency;

Now days the centrifuge is used in the interest of cosmonaut selection.

Technical features:

1. Rotation radius - 7 m;

2. Maximum overload

- 20 g;

3. Maximum load gaining rate

- 7 g/sec;

4. Motor capacity

nominal

- 820 kW;

starting

- 1280 kW.

5. Free suspension cabin

6. Reduction less design.

Сentrifuge TsF-18

It’s been operating in GCTC since 1980. It is used for cosmonaut selection and training by simulating the bad factors of space flight. Those factors are:

longitudinal g-load;

physiological micro gravity;

low cabin pressure, different temperatures, humidity, gas composition of the cabin’s air.

Technical features:
In terms of design TsF-18 comprises the following:

primary electrical drive;

tube design truss with counter weight;

cabin attached by three-degree suspension.

The weight of the centrifuge rotating elements is 300 t and the shoulder radius is 18m. It is the biggest centrifuge in the world and has unique technical features:

maximum load

- 30 g;

maximum load gaining rate

- 5 g/sec.;

starting capacity of the primary electrical drive

- 27 MW;

cabin’s pressure range

- from 800 to 40 mm Hg per 9 minutes;

cabin’s temperature range

- from +5 up to +50° C;

cabin’s humidity

- from 30 to 70%;

limits for percentage gas composition of the cabin:

Nitrogen

- from 56 to 83%;

Oxygen

- from 17 to 40%;

Carbon dioxide

- from 0 to 4%.

TsF-18 centrifuge has three changeable cabins (A,B,D). Cabin “A” is intended for research and training of cosmonauts and has two working seats. Cabin “B” is designed for special medical research and has X-ray equipment. Cabin “D” is used to gain the descent control skills and has a mock-up of the working seat for manned space vehicle.
There is a medical-physiological complex to ensure cosmonaut’s health monitoring during training.

TsF-18 training options

During centrifuge training cosmonauts are affected by maximum load varying from 5g for “head-waist” direction and 8g for “chest-back” direction.

Along with cosmonaut training TsF-18 centrifuge performs special tests and research of space and aviation equipment under load affect.
