STUDY OF A FAIL-SAFE ABORT SYSTEM FOR AN ACTIVHLY COOLED HYPERSONIC AIRCRAFT, VOLUME I, TECHNICAL SUMMARY by C. J. Pirrello and R. L. Herring McDonnell Aircraft Company 1. SUMMARY A detailed study was conducted to conceptually design and evaluate a fail-safe actively cooled structural system which will be used in an abort mode from cruise Mach numbers of 3 to 6. Study of a fail-safe abort system for an actively cooled hypersonic aircraft: volume I--technical summary / By C. J. Pirrello, joint author. R. L. Herring, United States. National Aeronautics and Space Administration., McDonnell Douglas Corporation. and Langley Research Center. The fail-safe concept depends on basically three factors: (1) a reliable method of detecting a failure or malfunction in the active cooling system, (2) the optimization of abort trajectories which minimize the descent heat load to the aircraft, and (3) fail-safe thermostructural concepts to minimize both the weight and the maximum temperature the structure will reach during descent. The fail-safe concept depends on basically three factors: (1) a reliable method of detecting a failure or malfunction in the active cooling system, (2) the optimization of abort trajectories which minimize the descent heat load to the aircraft, and (3) fail-safe thermostructural concepts to minimize both the weight and the maximum temperature the structure will reach during : R.

The Fail-Safe Abort System TEMPerature Analysis Program, (FASTEMP), user's manual is presented. This program was used to analyze fail-safe abort systems for an actively cooled hypersonic aircraft. FASTEMP analyzes the steady state or transient temperature response of a thermal model defined in rectangular, cylindrical, conical and/or spherical coordinate : Sr. L. A. Haas. Conceptual designs of a fail-safe abort system for hydrogen fueled actively cooled high speed aircraft are examined. The fail-safe concept depends on basically three factors: (1) a reliable method. The detection of a serious system malfunction in an actively-cooled hypersonic aircraft of course requires the effective emergency action be taken to slow the aircraft to a speed at which the radiation equilibrium temperature does not exceed the allowable temperature of the aircraft structure.
