NUCLEAR BLAST VULNERABILITY OF SHELTER ELECTRICAL GENERATING EQUIPMENT - DIESEL ENGINE OVERPRESSURE TOLERANCE

Abstract

Nuclear blast tolerance of internal parts of an operating diesel engine was tested by exposing the exhaust system, and simultaneously the intake and exhaust system to simulated overpressure air. Peak overpressures as high as 100 psi were applied. When the engine exhaust was subjected to overpressure, the engine speed was momentarily but noticeably reduced and the combustion chamber peak pressure was slightly increased. With the intake and exhaust system exposure to overpressures, the engine speed was only slightly affected and the peak combustion chamber pressure was greatly increased. This pressure reached 4400 psi at 100 psi overpressure, thus increasing the internal load to over four times that of normal engine operation. The diesel engine under test withstood repeated overpressure applications of 100 psi without any failures.
