Abstract
The LOC 835 high-power rocket with J275W-12 motor at Argonia, KS, for L2 certification, was auspiciously launched and returned. J means the motor can exert 640-1280 Ns of impulse, which makes a sizeable propelling sound. Even though four main hindrances occurred from the construction to the launch, the issues were revised correctly. The rail button and the tracker were severe issues, so I devised the method of drilling a hole for the rail button, but there was no way to replace a broken tracker. The wind speed on the launch day was so strong that the rocket flew 1-2 miles away. Thanks to the farmer driving his car, I could successfully retrieve the rocket and get L2 certification from certified staff. Indubitably, a deeper hole I drilled in the grain might have exploded the rocket. Thanks to the help from the board members, I could figure out how to solve the problem by bedding an epoxy into the hole. After the L2 certification launch, I would like to implement dual deployment and prepare for the night flight, inspired by a good talk with Dr. Paul Adams on the way home. Even though rocket building is stressive since we need to predict possible problems before we assemble the rocket, successful launch melts stress away.
