This page consists of an overview of the many systems that make up Project Redirect, ranging from test payloads to parachutes. Also included are images and videos related to these systems
A note on terminology; Often a single system will have several different versions. To aid in differentiation between these versions they are separated into different numbered generations, or gens. A higher gen number signifies a newer system. This gen number is often added to the end of a system’s acronym (ex. GTP-2).
The Parachute System
The Project Redirect parachute system is one of the most important systems as it is responsible for safely landing the payloads. Development of this system was completed in June 2019.
Our, first and most developed type, the spring powered parachute system, uses a spring to launch the parachute.
The Gen 0-S parachute systems were simple models constructed with household items such as jars and left over springs. These models were used to determine the feasibility of a spring powered parachute system.
Constructed with cardboard and sprinkler parts, the Gen 1-S parachute system was a simple proof of concept model used early in the development process. The Gen 1-S was in use for a few days and during that time performed only a couple of tests. These tests revealed the need for a better release mechanism. Most of the Gen 1-S was repurposed into the Gen 2-S. More
The Gen 2-S improved on the Gen 1-S by adding a simple, 3D printed, release mechanism. This mechanism, made the system easier to use and helped guide the design for future Gens. After a few tests we begin to work on the Gen 3-S and the Gen 2-S was retired. More
The Gen 3-S marked many firsts for the parachute system. It was the first to be made of fully 3D printed parts and to utilize purpose bought springs. The Gen 3-S also used a servo powered release mechanism. If it were not for the numerous problems that were mostly fixed in the Gen 4-S, the Gen 3-S would have been the first parachute system to fly. More
The Gen 4-S was similar in many ways to the Gen 3-S, it was simply a more refined version. The Gen 4-S solved most of the Gen 3-S’s issues such as: week hinges and bad servo placement. Unfortunately, the Gen-4-S did not fix the issues with release mechanism power. More
The CO2 powered parachute systems are newer than the spring powered systems.
Like the Gen 0-S, the Gen 0-C was a simple model used to test the validity of a CO2 powered parachute system. It was made of parts of the Gen 3-S to save time and funds. More
Pilot Parachute Assisted Deployment
A unique system that uses a small pilot parachute to deploy the larger main parachute.
Like the other Gen 0s, the Gen 0-P was used to test a concept for a parachute system. The Gen 0-P used a spring from the Gen 0-S as well as a Gen 3-S release mechanism. More
The Gen 1-P was a 3d printed version of the Gen 0-P. The tube and release mechanism are almost identical to the ones used in the Gen 4-S. More
The Gen 2-P was the first flight ready parachute system. The Gen 2-P consisted of a Gen 1-P pilot parachute launcher integrated with a main parachute tube and a parachute test payload attachment module. More
The Flight Test System (FTS)
The FTS is designed to test various components of Project Redirect in a real world environment by lifting them to a altitude of up to 121 m (400 ft) and dropping them. The FTS is capable of lifting up to 6.6 kg (14.6lbs) allowing it to carry and drop a wide variety of test payloads. The FTS is also equipped with a camera to record the performance of the test payload. More
The Test Payloads
Project Redirect makes use of many test payloads. These test payloads are dropped from the FTS (Flight Test System) to test different systems of the project.
Parachute Test Payload
Used to flight test prototype parachute systems without risking expensive components, the Gen 1 Parachute Test Payload flew in parachute system test 11. In a effort to reduce it’s cost and complexity, it was not designed to be reusable and is only capable of performing a limited number of flights. More
The PTP-2 (Parachute Test Payload, Gen 2) is a retrofitted version of the PTP-1 with upgrades including a new drop system and expanded electronics storage. This retrofit was designed to create a more flexible and reusable PTP for PSCC (Parachute System Control Computer) testing. More
Guidance Test Payloads
Guidance Test Payloads (GTPs) are used to test the components of the guidance system in flight. The GTPs are much more advanced than the parachute test payload.
Due to advances in construction techniques that rendered the Gen 1 GTP obsolete, it was retired and replaced by the Gen 2. More
Parachute System Control Computers
Parachute System Control Computers (PSCC) are compact flight computers that are designed to record data during test flights and automatically deploy a payload’s parachute at a preset altitude.
The PSCC-1 was the first generation of the PSCC to be tested. It used both GPS and air pressure sensors to determine it’s altitude. It was also equipped with a small LCD screen to aid in debugging. More
Built to replace the destroyed PSCC-2, the gen 2 used an upgraded GPS module as well as other improvements to fix the previous generations shortcomings. More
