Integrated Powerhead Demonstrator

The integrated powerhead demonstrator (IPD) was a U.S. Air Force project in the 1990s and early 2000s run by NASA and the Air Force Research Laboratory (AFRL) to develop a new rocket engine front-end ("powerhead", sometimes also termed a powerpack) that would utilize a full flow staged combustion cycle (FFSCC). The prime contractors were Rocketdyne and Aerojet.

The long-term design goal was to apply the advantages of FFSCC to create a reusable engine with improved life, reliability and performance. The powerhead demonstrator project was to develop a demonstrator design of what could become the front-end for a future engine development project. No subsequent funding was made available by public policymakers, so no full engine design was ever completed.

The turbines were also planned to feature hydrostatic bearings instead of the traditional ball bearings.
