Airblast Pressure Transducer for Measurements in Nuclear Blast Simulators.
Abstract
An extremely rugged resistance-based blast pressure transducer is developed over a number of years for use in the blast and shock environment of high explosive-driven nuclear blast simulators. A novel silicon disk with integral (diffused) strain sensitive regions is used as the transduction element for measurements of peaks to 69 MPa and requiring microsecond rise time response. Evolution of the transducer geometry, internal configuration, and special thermal barriers enable sensing applications in extremely violent shock environments to 50 kgs with intense flash and burn thermal environments. A variety of transducer mounting hardware configurations enables side-on sensing of incident overpressure and head-on sensing of reflected and stagnation pressures in a variety of simulator field test configurations.
