[Example] Continuously cooling the rocket motor.

Simulating sub-zero conditions in the heat of the Utah desert! A case of continuously cooling a motor in extreme heat.

We would like to introduce a successful case of testing a crewed flight solid rocket motor, made possible by the introduction of a specially designed adaptable air cooling system for Orbital ATK. The cooling motor test was a crucial test to prove that the motor could operate at low temperatures, but it was necessary to keep the motor and propellant at 40°F (5°C). Maintaining such low temperatures in the testing facility in Utah, where temperatures exceed 100°F (38°C), was extremely challenging. Our company designed an air cooling system equipped with a chiller unit that has three double-stacked low-temperature air handlers with defrost capabilities. Just before the live test, we removed the equipment from the building and operated a custom air duct system to cool the DM-2 joint until one minute before the rocket launch. [Challenges] - It was necessary to keep the motor and propellant at 40°F (5°C). - An integrated electric defrosting device was required. - It was essential to maintain the air at the appropriate temperature. *For more details, please download the PDF or feel free to contact us.*
