Setbacks (Part 2)
Part one here We decided to try the spring powered parachute system one last time before scrapping the idea. We wanted to know if the length of the springs effects the power of the parachute system. The “power” of springs is measured in rate(lb/in). Rate is how much force (in lbs) it takes to compress…
The Flight Test System; an Overview (Part 2)
Click here for part 1 The second subsystem of the FTS (Flight Test System) is the test payload. It will be dropped by the S1000+ from 106.7 m (350 ft). Above is a 3D model of the guidance system test payload. The test payload will differ in design depending on which system will be tested. …

The original design of the parachute system used ballistic deployment. This meant the system would use springs, CO2, or pyrotechnics to force the chute from the tube it was stored in. The main advantage of a ballistic parachute system is that the significant speed of the parachute after launch, decreases deployment time of the parachute….
GPS
Our research into a new GPS module for the Parachute System Control Computer (PSCC) led to a promising discovery; advanced GPS modules are available that utilize Real-Time Kinematic (RTK) data to determine position and altitude with an accuracy of a few centimeters. RTK data provides the GPS with information it needs to correct for the…
Setbacks
This week we returned to working on the parachute system. With the new receiver, we were able to set up the release servo motors. After some testing, we realized that the servos we originally planned to use did not fit our specifications. Fortunately, we were able to repurpose some other servos we had on hand….
Status Update
Months ago, when we began designing the parachute system, we decided to use springs to deploy the chutes. We chose springs because they are reusable and simple. We planned to spend no more then a month working on the parachute. However, after hundreds of hours of planning, designing, printing, testing, and redesigning, the spring powered…
