ABSTRACT:
A shock tube assembly for simulating high energy detonations includes a driver section, a diaphragm section, an expansion nozzle, an expansion tube and an improved system for providing a heated and pressurized gas for the driver. After preheating the improved pebble-bed evaporator and superheater, gas or liquefied gas from a pressurized supply flows temperature. The output of the pebble-bedheater flows through a mixer for control of the temperature of the gas used to charge the driver. The pebble-bed heater is preferably vertically oriented and includes spaced baffles having flow apertures arranged in concentric circles. The apertures of each circle are connected by a groove to permit flow of gas through the aperture in the event that a pebble element rests on the open end of the aperture. This system allows very driver rapid fill times and makes possible the use of hot gas in uninsulated, unheated drivers to eliminate contact surface discontinuity and thereby produce near ideal static and dynamic pressure profiles.
