  7. Abstract:
  8. The weight characteristics of the aircraft, including the location of the center of mass, has a direct and important impact on its stability and control. For example, air dropping is one of those cases in which weight characteristics are subject to considerable changes. Today, the development of algorithms for accurate estimation of weight characteristics has flourished both on-line and off-line. Therefore, it is important to develop the means by which kinetic-based estimation algorithms can be tested. The device should be efficient both in terms of mechanical performance and Implementation capability. To do this, we have to design an outline of the machine, which has the same dynamics as a specific aircraft. Then we will simulate the device designed by ADAMS dynamic analysis software. The test performance of each of the estimated algorithms will be done by generating data with the simulated system and comparing its output with the weight specification that is set here position of center of the mass. After these steps, considering the electrical motors and sensors in the market, we will select and design of the subsystems of this system, and finally, by selecting the subsystems and determining the exact installation location of each, and the location of the connections, the design map will be extracted
