We started the day with the planned tests of the wing simulators. The modified third generation Parachute Test Payload (PTP-3) had three possible configurations that we tested, with the goal of evaluating the effects of the different wing sizes on a payloads stability during ascent. With all of these tests we endeavored to keep the…
For the first time since the catastrophic crash that destroyed the first generation Parachute System Control Computer (PSCC-1), we returned to the test site. As the PSCC-2 had been extensively tested on the ground, the next step was to perform a flight test that would subject it to an environment very similar to the one…
After the results of our last tests, we were feeling confident that the PSCC (Parachute System Control Computer) was approaching a functional sate. During our latest in a series of tests, all aspects of the PSCC code worked as expected, with the only issue being a recurring discrepancy in the GPS and air pressure altitude…
A little over a week later we returned to the test site, once again ready to test the PSCC. This time we were better prepared, bringing with us a wider selection of tools and an upgraded battery charger that could charge the FTS’s (Flight Test System) battery much faster. While originally we planned to fly…
Development of the PSCC code that would automatically deploy the parachutes proved much easier than expected. Only a few days after the GPS issue was solved, this code was ready for testing. Functionally, this version of the PSCC code is simple and functions as follows: During operation the code takes altitude readings from the PSCC’s…
The PSCC (Parachute System Control Computer) is a small computer that will be used to deploy the parachutes at a preset altitude. A few months ago, we performed the first flight test of this system. This test recovered useful data but also revealed that the GPS (a vital PSCC sensor) was reporting an incorrect altitude…
After our most recent FTS (Flight Test System) test flight it became apparent that a new method of attaching payloads to the FTS was needed. Originally, payloads were attached to the FTS via the drop system which was mounted below the FTS, but with the removal of the drop system from the FTS we were…
In the past few weeks we have made significant progress with both the GTP (Guidance Test Payload) and PSCC (Parachute System Control Computer). This continues to bring us closer to the first test flight of the GTP. With the arrival of new 3D printing material (filament) we were able to print the rest of the…
Now that we have decided on the building materials for the GTP (Guidance Test Payload), we can start assembling it. The Gen 2 GTP will be made up of two segments; the parachute segment and below it, the electronics segment. Each segment has two parts; the outer shell and inside it, the module. The outer…
