AFRL confirm feasibility of SABRE engine concept


Analysis undertaken by the US Air Force Research Laboratory (AFRL) has confirmed the feasibility of Reaction Engines’ Synergetic Air-Breathing Rocket Engine (SABRE) engine cycle concept.

The analysis was undertaken by AFRL as part of a Cooperative Research and Development Agreement (CRADA) with the Air Force Research Laboratory’s Aerospace Systems Directorate (AFRL/RQ).

The investigations examined the thermodynamic cycle of the SABRE concept and found no significant barrier to its theoretical viability provided the engine component and integration challenges are met.

Reaction Engines and AFRL are now formulating plans for continued collaboration on the SABRE engine; the proposed work will include investigation of vehicle concepts based on a SABRE derived propulsion system, testing of SABRE engine components and exploration of defence applications for Reaction Engines’ heat exchanger technologies.
