Nuclear Blast Response of Airbreathing Propulsion Systems. Laboratory Measurements with an Operational J-85-5 Turbojet Engine
Abstract
The work discussed in this report represents a technology development program in which an experimental technique has been developed for the performance of controlled laboratory measurements of simulated nuclear blast response of airbreathing propulsion systems. The technology program utilized an available J-85-5 turbojet engine located in the test section of the Calspan Ludwieg-tube facility. Significant modifications, described herein, were made to this facility in order to adapt it to the desired configuration. The J-85-5 engine had previously been used at Calspan for other purposes and thus came equipped with a total of eight pressure transducers at four axial locations along with compressor section. These transducers have a frequency response on the order of 40 KHz. Preliminary comparisons have been made between the measured pressure histories at selected compressor locations and predicted pressure histories using a simple computer code. The development of the code was initiated under this contract and completed as part of an ongoing IR&D effort at Calspan in computational fluid dynamics and problem areas related to engine dynamics.
