Correcting thruster device (KDU)
The correcting gas-jet engine is the executive instrument of
the subsatellite control system and is designed for generating
tractive force impulses:
Fig. illustrates locations of KDU and controlling nozzles on
a subsatellite with respect to its axes.
- 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
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|
