Payload Adapter for Satellite Missions Launched Using ICBM-Derived Launch Vehicles

Deactivated ICBMs are a logical means of putting payloads into space, but missile systems are not designed for satellite launches, and payload accommodations on deactivated missiles are inadequate for standard payloads. Furthermore, the vibration andacoustic environments during launch of an ICBM are much more severe than the environments seen on a rocket developed specifically for satellites. The need for new, low-cost launch vehicles combined with the availability of these deactivated ICBMs drive aneed to develop a payload adapter to manifest multiple satellites on these new vehicles. CSA Engineering is developing a modular, composite Dual Payload Attach Fitting (DPAF) system with integrated vibration and acoustic suppression capability. Thisadapter system will mount two spacecraft in the 2000-lb class or a 2000-lb primary payload and up to four smaller secondary payloads. The DPAF will be a lightweight all-composite structure designed specifically for the Peacekeeper ICBM, but adaptable forMinuteman and other booster systems. Low-shock separation of the DPAF will complement vibration damping and whole-spacecraft isolation capabilities, which have become proven technologies for reducing the dynamics environment during launch. This programwill develop new technology by integrating all these types of vibration suppression into a low-cost, lightweight, composite DPAF.
