Research and Technologies for Aerospace Propulsion Systems (RTAPS)

The Research and Technologies for Aerospace Propulsion Systems (RTAPS) Indefinite Delivery/Indefinite Quantity (IDIQ) contract is a NASA-managed vehicle supporting advanced aerospace research and technology development across multiple propulsion domains. The contract focuses on critical technological areas including communications, structures and materials, power systems, and propulsion technologies for both aeronautical and space applications. Through this IDIQ, NASA seeks to advance long-term aerospace research programs by engaging multiple prime contractors to develop, demonstrate, and verify emerging technologies that can potentially transform aerospace engineering capabilities.

Task orders under this IDIQ consistently target high-complexity technology development efforts, with typical values ranging from approximately $20,000 to $12 million and durations spanning several months to multiple years. Key contractors appearing in the task orders include Honeywell, Rolls-Royce, and various aerospace research firms, with most task orders being either Firm Fixed Price or Cost Plus Fixed Fee. The vehicle predominantly supports research in air-breathing engine technologies, space propulsion systems, and advanced materials development, with a strong emphasis on innovative propulsion concepts such as turbine-based combined cycle (TBCC) systems, electric propulsion architectures, and advanced engine component design. Most task orders are not set aside for small businesses, and they consistently involve NASA Glenn Research Center and other NASA research facilities as the primary places of performance.
