Calculation of Displacements to Correct the Mounting Locations of Devices When the Mass Limits Are Exceeded in the Placement Zones in Compartment

When designing the aircraft devices layout, it is necessary to ensure a specific position of the compartments’ centers of mass while minimizing the lengths and masses of the cables connecting the devices. This problem can be solved using expert methods (heuristically), but when optimizing the layout, many other factors must be taken into account. Therefore, a computational approach is essential for providing the systematic development of layout solutions. The issue of determining the direction and magnitude of devices movements to ensure the fulfillment of mass centering and inertial requirements for the layout of on-board equipment inside the spacecraft compartment has been researched. Mathematical models have been developed for cases of displacement of one instrument and several instruments, including in the presence of several equally accessible placement zones. A general algorithm of actions has been built, and examples of its development are given. An analysis of the results showed that geometric constraints have a significant impact on the calculation results and, in some cases, require additional consideration. There may also be situations where increasing the distances between functionally connected devices is unavoidable to ensure compartment alignment, and such devices layout needs to be rearranged.
