St. Vincent – St. Mary FRR Presentation NASA Student Launch Initiative
Final Launch Vehicle Dimensions Length: 127.6 in Diameter: 5.54 in Span Diameter: 19.0400 in Mass: 29.5 lbs. with ballast Center of Gravity: 82.1 in Center of Pressure: 90.4 in Static Margin: 1.5
Key Design Features • Dual altimeters • Payload piston ejection system • Airship inflation system • Airship release system • Boat-tail
Final Motor Choice The final motor we are using on our full scale rocket is a Cessaroni K660. We chose the K660 because it has the ideal thrust for our full scale rocket design. The motor also has a fast burn time, allowing the rocket to reach maximum speed faster and provide better launch stability
Rocket Flight Stability Margin 1.5 Thrust-to-Weight Ratio 5.46 Rail Exit Velocity 38.09 ft/s
Mass Statement Our mass margin is zero ( We are overweight) The rocket weighs about 29.5 pounds. The rocket is at its limit on weight, any more and it will be hard to reach the expected height.
Parachutes and Recovery Harness Main Chute – Skyangle Size 7 Recovery Harness – Area: 56.8 sq.ft Type: Tubular Nylon Mass: 40.9132 oz Size: 5/8 in w x 25 ft l Descent Rate: 13.84 ft Drogue Chute – Cert-3 Area: 6.3 sq.ft Mass: 6.00 oz Descent Rate: 75.5ft/s
Kinetic Energy After drogue parachute is deployed After main parachute is deployed
Test Plans and Procedures • Tests • Airship inflation • Airship release from the rocket
Full Scale Flight Test Flight Information • Motor Used: Cesaroni 1635k445 • Altitude: 2000 ft. • The rocket was fired without the payload. Bags of sand were used as weights to simulate the payload in the rocket.
Payload Integration The main parachute will sit in the top of the forward rocket body tube and will rest on the airship. Below the airship is a rocket body tube coupler and bulkhead that will serve as a piston to push out the main parachute, airship, and nose cone.
Interfaces • RC-Airship • RC-Airship Inflation System • RC-Airship Disconnect • Altimeter On/Off Switches
