2Rocket Flight Stability
- Via Rocksim, the new data has been uploaded and
tested. - Rocksim simulations have been run, verifying our
rockets flight worthiness. - Test flight on 3/9/08 positively confirmed
stability.
3CG-CP
4Rail Exit Velocity
- Rocksim analysis, 6 Diam, 40 lbs loaded with
L1300, 10 rail - Rail Departure Velocity35 ft/sec
- Minimum velocity for Stable flight46ft/sec
5Rocket Specifications and Performance
- Total length of vehicle10ft, 9in
- Diameter of vehicle airframe.6in
- Liftoff Mass fully loaded.45lbs, 10oz.
- Vehicle stability positive two caliber (airframe
diameter) Separation between CG and CP (center of
gravity and center of pressure) - Thrust to weight ratio..6.48 1
- Liftoff velocity off launch rail..35
ft/sec - Maximum velocity during flight..700ft/sec
- Time to Apogee (peak altitude).20.5 sec
- Drogue chute descent Velocity.76f
t/sec - Main parachute deployment at ...800ft AGL
(above ground level) - Descent velocity rate on main chute...19.8ft/s
ec - G-Forces experienced by rocket and
payloads...5.86Gs - Maximum Altitude achieved at apogee.5,216ft
AGL - NASA required an apogee of.5,280ft AGL
- Pitot Cruiser RDV was 64ft off the NASA required
target altitude.
6Motor specifications and performance
- Motor used L1300 APCPR
- L Total Impulse in Newton-seconds
- 1300 Average Thrust in Newtons
- 4.45 Newtons 1 pound of thrust
- Our motor has an average thrust of 292 pounds
- APCP Ammonium perchlorate composite propellant
same fuel and oxidizer used on the Space
Shuttle Solid Rocket Boosters (SRBs) - R Reloadable motor (motor case can be reused
again) - Manufacturer Aerotech
- Propellant mass 2,632g 5.8lbs
- Total Impulse rating 4,567 Newton-seconds
- Total Impulse is proportional to the total energy
released by the propellant in a propulsion system - Motor dimensions 98mm diameter x 443mm length
(3.9in diameter x 17.4in length - Burn time 3.5 seconds
- Burn time is calculated by dividing the Total
Impulse by the average thrust ratings L5120
Newton-seconds - Thrust to weight ratio 50 1
7Parachute Sizes and Descent Rate
- Five parachutes
- 1- 36 drogue chute
- 78.3ft./sec. descent rate
- 1- 45 nose cone chute
- 19.8ft./sec. descent rate
- 1- 45 capsule chute
- 19.8ft./sec. descent rate
- 1- 120 main chute
- 20.8ft./sec. descent rate
- 1- 12 safety chute for Mission Cdr. Gumby
- 28.6ft./sec. descent rate
Rocket Hunter frequency is 219.719 MHz
8Test Plans and Procedures
- Robot Pilots practicing control via radio/video
link - Pitot tube 220MPH leafblower test done
- BP ejection test done
- CO2 ejection test done
- Flight video successful integration into
nosecone! - 1st test flight successful!
9Scale Model Flight Test
- ½ Scale model flew successfully, with Video!
- 1st Pitotcruiser RDV flight 3/9/08
- Internal video camera running during flight.
10Dual Deployment of Avionics Test
- Dual Avionics Payload
- Aft Black Powder 3g
- Fore Carbon Dioxide (for low temperature,
noncorrosive gasses on robot. 38g x 2) - Dual, redundant altimeters for maximum flight
safety. - Worked perfect, 3/9/08!
11Ejection Charge Amount Test-CO2
- Forward Section Ejection, 38 gram cartridges, x2
- Components of CO2-Rouse-Tech, has been test fired
twice. - Successfully ejected main at 800 on 3/9/08!!!
12Ejection Charge Amount Test-BP
- Aft Section Black Powder Ejection Charge section.

3/9/08!!!
13Nosecone Pitot/Video payload
- Circuit integrated fully into nosecone
- ½ Plywood Flange epoxied screwed in nosecone
- 5 bolts hold bulkhead to flange
- Offset center for ease of reaching switches
- Camera below pitot electronics.
14Nosecone Pitot circuit
- Same circuit as last year
- Tube to Hose to Sensor to Data Logger
- Data downloaded to Laptop PC, Excel
- Calibration via 220MPH blower
15Mission Commander
- Team Orion is honored to have a passenger!
- Gumbys safety is mission critical
