Multiple payload adapters; opening the doors to space

In order to increase the number of satellites that can be flown on a small, fixed budget, low-cost multiple payload adapters (MPAs) are needed to take advantage of excess payload capability on launch systems. This paper will discuss the development of several MPAs at the Air Force Research Laboratory-Space Vehicles Directorate (AFRL/VS) in support of current and future Air Force and DOD requirements. The adapters are being designed using state-of-the-art manufacturing processes, launch vibration isolation, and low-shock separation technology that can accommodate multiple satellite configurations. The MPAs can deploy multiple satellites, in a large range of sizes (15 kg to 1000 kg), depending on the design configuration. The MPAs are being developed to support the Minotaur, the Evolved Expendable Launch Vehicle (EELV), as well as the Space Shuttle. The successful development of these adapters will greatly reduce the cost of launching satellites into orbit by allowing for the efficient use of currently unused payload margins.
