Abstract: An ammunition propellant temperature measuring assembly comprising a first emperature measuring device for determining at least two surface temperatures of a round of ammunition and for transmitting a first signal indicative of the surface temperature, a second temperature measuring device for determining ambient temperature in a storage area for the ammunition and for transmitting a second signal indicative of the ambient temperature, and computer apparatus for receiving the first and second signals and a temperature profile for the ammunition, and adapted to compute therefrom a propellant temperature of the round.

Abstract: An ammunition temperature emulating system is provided for use in a tank ch carries ammunition. The temperature of the ammunition (which comprises liquid propellant) is needed to be known for firing accuracy. The temperature is indirectly approximated by measuring the temperature of the wall of the chamber in which the ammunition is stored, using a simulating thermal insert. The system includes a gauge having a sensor bulb, a vacuum bottle having a cavity receiving the sensor bulb and receiving the simulating thermal insert.
