- Abstract
The development of space microgravity technology is one of the most perspective ways of the modern aerospace engineering. At the present time there are different directions of the space microgravity high-technology development such as the growing of high-performance semiconductor homogeneous crystals under space vacuum and microgravity conditions, production of medicine preparations of extreme purity, realization of important researches in biology, fundamental research in many areas of physics such as the processes sensitive to gravity level and direction, etc. Unfortunately, almost all attempts to realize these technological processes onboard modern spacecraft were not quite successful. Deep and wide research of this fact using numerous Russian, American, German, French and other experimental results showed that microgravity conditions on board contemporary universal and large spacecraft did not allowed to have necessary conditions. These conditions are: - the onboard equipment has to be located in the mass centre of the spacecraft and oriented in special direction along microgravity vector; - the level of onboard microgravity has to be very low, about (10-8 – 10-7)g0, where g0 is the normal Earth gravity acceleration; - the onboard residual acceleration vector has to be stable in space and in time. As shown in [1, 2] a special small satellite will allow to realized these conditions on its board. Obviously it is necessary to examine this idea during the flight of a small satellite with gravity stabilization system. It is very important to carry out the space experiment with dynamic measuring of the onboard residual acceleration vector, using high-level sensitive instrumentation. We suggest having five accelerometers. First of them will be placed at the mass centre of the small satellite, second and third will be placed at the “highest” and “lowest” points of the satellite volume, forth and fifth at the “left” and at the “right” of the mass centre. To increase reliability experimental information we suggest using two different types of onboard accelerometers, Russian and Belgian for example. Besides, we think to supplement the direct measuring of the onboard micro-gravity environment using ballistic data and synchronous information about magnetic field at the satellite orbit that can be used to calculate the residual micro-accelerations.
