Introduction: The idea of using slingshots or other mechanisms to launch spacecraft into space was proposed in the 1920s. However, due to technical problems that seemed insurmountable at the time, it was not developed further. However, modern advances in astronautics, such as the use of ultra-high-strength materials, miniaturization of spacecraft instruments and components, and the need to address challenges such as asteroid mitigation, small spacecraft launches, orbital constellation deployments, and space object inspections, necessitate reconsidering this idea and developing new space technologies. These include rotary launch devices (RLDs), which impart the required rotational motion to their target systems relative to specific axes of the devices to perform their intended tasks. Research Objective: Develop new payload delivery systems to a given point in space. Methods: Systems analysis methods were used to achieve this objective. Results: The main types of RLDs were identified, and their composition and method of application were described. Practical signifi cance: the devices proposed in the article make it possible to expand the range of orbital-based vehicles with technical simplicity and insignificant mass-dimensional characteristics, capable of reliably solving the problems of launching spacecraft and their constellations of various purposes, various types of payloads into specified orbits with low energy consumption and without impact on structural elements and payload. Keywords: space, rotational launch devices (RTLD), space objects, space technologies. DOI: 10.25791/aviakosmos.5.2026.1557 Pp. 33-38.
