Pair of copper channel wall test pieces from a COBRA booster engine developed for NASA by Pratt & Whitney–Aerojet Propulsion Associates in 2002, measuring 12? x 6? and 15.5? x 5?, with the top side ribbed and the underside smooth. In fine condition, with expected wear from use. In 2001 Pratt & Whitney and Aerojet teamed to provide a wide range of main propulsion options in support of NASA's conceptual second generation, reusable launch vehicles. COBRA was proposed as a long-life, moderate-to high-thrust, reusable booster engine that incorporated a safe, low-cost, low-risk, LH2/LOX single burner, using a fuel-rich, staged combustion cycle.
