Investigation of Jet Engine Combustion Chamber Burn-Through Fire.
Abstract
Work was directed toward establishment of standard test conditions for testing materials which are intended for use as fire barriers for protection against a jet engine combustion chamber burn-through type of failure. The development of such a failure was accomplished on a General Electric J-47 jet engine. The resulting flame was quite severe, penetrating the present standard firewall material in 2 seconds. Studies were made of the flame impingement characteristics, including impingement temperatures and pressures; and various potential firewall materials were tested for effectiveness as fire barriers for protection against such a failure. Most materials tested in this manner failed to provide adequate protection against such an engine failure. An investigation was conducted toward development of a means of simulating a combustion chamber burn-through failure with the ultimate goal of developing a suitable laboratory test flame for evaluating potential firewall materials. A combustion chamber simulator, which will produce a flame of similar severity to the flame produced in the J-47 engine, was developed. However, more effort is required to further develop this simulator so that exact simulation is possible. (Author)
