Overview
Project Hermes is the team's entry to the 2018 IREC Unlimited Category. It is entirely SRAD. The design was conceived during summer of 2017. It is a single stage, 6in, minimum diameter rocket with a single separation point.

Recovery System
The Hermes recovery system is a piston-actuated, single separation-dual deploy architecture.
Propulsion System
Hermes Propulsion System (8-grain) is an eight-grain custom solid rocket motor that will provide propulsion for the vehicle.

Vehicles
Raziel PathfinderRaziel Pathfinder was an unflown Test Article from 2016-2017's Project Raziel. After undergoing extensive modifications, the pathfinder was uprated to flight hardware. The construction of this vehicle is primarily E-glass. Early manufacturing limitations limit the maximum length of any tube produced using the old methods to 24in, so the fin can is held together with a coupler. Some of the tubes are distinctly out of round due to a low-quality mandrel used for initial production runs. The nosecone is a modified COTS gelcoat covered 4:1 Ogieve nose cone. |  |
Hermes 1Hermes I is the first build of a flight-ready Hermes rocket. Building on our experience with Pathfinder the structures team delivered an all-composite minimum diameter fin can. Andrew A. constructed a hexagon Avionics Tower. The rocket was designed to work with an 8G motor but was modified to accommodate the 4G motor it flew on by moving the motor retention bulkhead into the middle of the air frame. This rocket flew Hermes Flight 1 before being retired to the Rocket Garden in the Unified Lounge. Responsible Engineers Listed Here. Mass Budget here. This rocket was originally envisaged as flying in the 'Unlimited Category' at IREC 2018. Deliverables below: |  |
Hermes 2Hermes II is an iterative improvement on the Hermes I design, intended to eventually serve as a first stage for a spaceshot. This rocket is intended to fly an 8 grain motor. This rocket is receiving additional design work in the 'mystery box' area and avionics bay. |
