Successful Chronos Ground Test

In preparation for the upcoming Intercollegiate Rocket Engineering Competition (IREC) taking place in Green River, Utah, members of the YUAA Rocket Competition Team ground tested Chronos to make sure that the golden beauty would be ready for its debut launch. The series of ground tests had one thing in common: Success.

In the first phase of ground testing, the main parachute was deployed by placing a charge source in contact with a 9V battery. The Rocket Competition Team used 3.0 g of Pyrodex to supply the charge, and after touching the wires from the Pyrodex to the battery, the nose cone launched off, followed by the main parachute. Similarly, the the drogue parachute deployment was tested using 3.2 g of Pyrodex, and the outcome resembled the experiment that preceded it. At this point in the ground tests, the team was confident that Chronos would properly return to ground level after soaring thousands of feet above the Utah plains.

In the second phase of ground testing, Chronos was fully assembled to evaluate whether or not the Pyrodex would actually ignite at apogee. The team strategically replaced the Pyrodex pellets with LEDs and simulated the environment at apogee by using a portable vacuum. The vacuum emulated apogee conditions,  and as a result, the LEDs lit up, indicating a successful network of communication within the rocket.

Chronos is ready for you, IREC!
