Summary Size: 63.5 in. High, Diameter: 4 in. Mass: 117 oz. Motor: Cesaroni I350SS Recovery System: Two 72 in parachutes with drogues 36 in heavy duty thread Objective: Design a AGSE to autonomously load a payload. We will design a rocket that will reach an apogee of 3000 ft. At apogee the main recovery system will deploy Upon return the payload will be ejected at 1000 ft Both the payload and rocket stages will return safely.

Vehicle Criteria: Design 2 Stages Upper Stage with main parachute system Lower (payload) Stage with payload, engine, and secondary parachute system Mass (with engine): 117 oz. Center of Pressure: inches from tip Center of Gravity: inches from tip Stability Margin: 1.58 calibers Center of Pressure Center of Gravity

Rocket Stages Stage 1 Stage 2
