About this file
This document is a Statement of Work (SOW) that describes the requirements for four rope seals capable of surviving a 3000°F combustion environment in a Rotating Detonation Rocket Engine (RDRE). The contractor team will work with the Air Force to finalize the seal groove dimensions and the rope seal design, using either metal carbide carbon-graphite fiber or advanced near-stoichiometric SiC ceramic fiber. The contractor must provide proof that they have previously fabricated rope seals from these extreme-temperature-resistant fibers. The four seals will be delivered to the Air Force's RDRE test facility for evaluation.
The related federal contract opportunity is a Sources Sought (SS) notice from the Air Force Research Laboratory (AFRL) for the four 3000°F rope seals. This is not a solicitation, but allows the government to review industry capabilities. Interested small businesses must submit their credentials, including company information, small business status, and relevant experience, by October 9, 2024. No quotes or proposals are being accepted at this time.

Additional Work SOW // Minimum Requirements Document
3000F RDRE Extreme Combustion Environment Rope Seals
Background and Scope:
To date no one has created a rope seal made from any fiber capable of surviving the 3000F oxidizing combustion environment of a Rotating Detonation Rocket Engine (RDRE) for any relevant multi minutes of exposure duration. Two new fiber classes have recently come onto the market which have demonstrated the ability to sustain acceptable properties when exposed to 3000F oxidizing environments: Near Stochiometric SiC very low Oxygen content ceramics fibers are one, Post rope seal fabricated metal carbided fiber surfaces carbon-graphite fibers are a second. Fibers from these new classes need to be fabricated into, in part braided, rope seals and their survivability tested in an RDRE.
Requirements:
The contractor team will work with the AF’s Rotating Detonation Rocket Engine (RDRE) development branch to finalize the shape and dimensions of two seal grooves and subsequently the dimensions and constituent architecture of the extreme 3000F environment surviving rope seals designs capable of surviving the combustion leakage environment of a firing RDRE’s 3000F exhaust.
The contractor team shall fabricate four rope seals, two made from a metal carbide carbon-graphite fiber (which will subsequently be surface carbided modified/treated) and another two made from an advanced near Stochiometric SiC very low Oxygen ceramic fiber into the necessary final rope seal length forms. Both fibers must have previously demonstrated the ability to survive and maintain adequate extreme 3000F RDRE combustion environment relevant related properties and the contractor team must provide proof they have previously fabricated (to some degree braided) rope seals from these two extreme 3000F surviving fibers.
The contractor shall ship the seals to the Edwards AFB RDRE test facility for testing in an AF government RDRE.
The contractor shall document the results in a small final report.
Product Description:
Finalize the shape and dimensions of a seal groove and subsequently the dimensions and constituent architecture of an extreme environment surviving rope seal design capable of surviving the combustion leakage environment of the 3000F exhaust of a firing RDRE.
Fabricate four rope seals, two made from carbon fiber (subsequently surface modified/treated) and another two made from an advanced ceramic fiber, both fibers previously demonstrated to survive and maintain adequate extreme 3000F RDRE combustion environment relevant seal related properties.
Ship the four seals to the AF government RDRE test facility for testing.
