Ammunition propellant temperature measuring assembly

An ammunition propellant temperature measuring assembly comprising:

• a first temperature measuring device for determining at least two surface temperatures of a round of ammunition and for transmitting a first signal indicative of said at least two surface temperatures;
• a second temperature measuring device for determining ambient temperature in a storage area for said round of ammunition and for transmitting a second signal indicative of said ambient temperature;
• and
• a computer for receiving said first and second signal and a temperature profile for said round of ammunition corresponding to a relationship between said at least two surface temperatures, said ambient temperature, and the propellant temperature, for computing therefrom the propellant temperature of said round.

An ammunition propellant temperature measuring assembly for use with a gun that fires a round of ammunition, comprising:

• a first temperature measuring device disposed proximate a gun breech that receives ammunition, said first temperature measuring device determining at least two surface temperatures of the round of ammunition entering said breech and transmitting a first signal indicative of said at least two surface temperatures;
• a second temperature measuring device disposed in a storage area for said round of ammunition for determining an ambient temperature in said storage area and for transmitting a second signal indicative of said determined storage area ambient temperature;
• a first computer for receiving said first signal, said second signal, and a temperature profile for said round of ammunition corresponding to a relationship between said at least two surface temperatures, said ambient temperature, and the propellant temperature, and computing therefrom the propellant temperature of the round of ammunition, said first computer transmitting a signal indicative of said computed propellant temperature;
• a ballistic computer receiving said signal indicative of said computed propellant temperature from said first computer to refine an expected trajectory of the round of ammunition upon firing from the gun;
• a position sensor disposed proximate said first temperature measuring device for detecting movement of the round toward said breech and to signal said first temperature measuring device to begin a temperature measuring operation;
• and
• a reflector mounted proximate said gun breech on an opposite side thereof from said position sensor and in alignment with said position sensor to receive and reflect an energy beam from said position sensor, said signal from said position sensor to said first temperature measuring device being triggered by interruption of said beam by the round of ammunition moving toward said breech.
