Applications

Space Applications
The knowledge of microacceleration levels, their spectral composition, and their spatial distribution is a necessary condition for the effective utilization of manned space complexes as a means for achieving scientific and applied objectives, as well as for refining mathematical models and dynamic characteristics of various ISS stack configurations and for monitoring the structure’s remaining operating life.

Results/More Information

The results obtained during the sessions using this equipment have demonstrated that microaccelerations caused by dynamic station operations can excite convective flows in a heterogeneously heated gas environment. The root causes of convective flow excitation have been validated by comparing the Dakon-M results with angular rate sensor measurements. In particular, the tests have demonstrated that convection can occur as a result of continuous microaccelerations existing aboard the ISS, as well as of the accelerations related to boosting the station’s orbit and to docking and undocking with Progress-M and Soyuz vehicles.

A study of convective and isothermal flows caused by small inertial forces aboard the ISS RS was completed using the Dakon-M science equipment during the 2011 ISS increments. The performed studies show that the microgravity environment aboard the ISS RS is unfavorable for a number of experiments. To ensure the favorable conditions for microgravity experiments, Progress vehicles are proposed as a platform for such experiments after the spacecraft has fulfilled its primary functions. The performed experiments has shown that the Progress attitude control methods developed for this use can ensure microacceleration levels of at least 10-6 g, which is a unique achievement opening up broad possibilities for the implementation of science programs.

The expected scientific and engineering results of the Izgib experiment are related to the ability to obtain the inputs required for the development of both mathematical micro g-load models and a database on hardware-related impacts on micro g-load levels for different science hardware locations.
