Correcting thruster device

The correcting gas-jet engine is the executive instrument of the subsatellite control system and is designed for generating tractive force impulses:

to correct the subsatellite motion along its longitudinal Z-axis and perpendicularly to it; - to realize the subsatellite rotation around its longitudinal Z-axis and its damping;
to redirect the longitudinal axis (-Z) to the sunward direction.

Fig. illustrates locations of KDU and controlling nozzles on a subsatellite with respect to its axes.

Main technical characteristics of KDU are presented in Table.

Jet body	Compressed air
Tractive force of one nozzle for all conditions of its operation	0.1 +/- 0.007N
Normal pressure of the balloon filling for the environment temperature 20 C	22MPa
Range of pressure variations at the input	0.25-0.37MPa
Pre-start gas pressure in the cavity in front of	0.5MPa
Balloon volume	1.85 liters

Correcting thruster device was made in "Yuzhnoye" Design Bureau, Dnepropetrovsk, Ukraine.
