Today we made blueprints and started making our rocket. We have decided to use a parabola shaped nose cone because from the website below and many other reliable sources we have found that this is the best design to use. We have decided to construct the nose cone out of cardboard and duct tape because by using the rocket simulator I found that it was best to use that kind of material. Form Addison's use of the rocket simulator we found that it is best to use three fins instead of four because it decreases the rockets mass which helps it cut through the air quicker.

B.T.W. I will be posting the blueprint tomorrow because I forgot to bring my tablet home.

DATA SHEET

Flight One Flight Two Body: Payload Height (cm): 1.905 Nozzle Radius (cm):.9525 Fairing: Yes Fairing radius (cm): .007 oz/in2 Nose Cone: Shape: conical Material:Cardboard Propulsion: Water (liters):? Pressure (KPa): ? Fin Design: Fin Height: 1.5 Fin Shape: trapezoidal Number of Fins: 3 Fin Dimensions: 1.5 by 1 by 0 Body: Payload Height (cm): 1.905 Nozzle Radius (cm): .9525 Fairing: Yes Fairing radius (cm): .007 oz/in2 Nose Cone: Shape: Conical Material: Cardboard Propulsion: Water (liters): ? Pressure (KPa): ? Fin Design: Fin Height:  1.5 Fin Shape: Trapezoidal Number of Fins: 4Fin Dimensions: 1.5 by 1 by 0 Launch Stats: Max Altitude (m): 34 Max Velocity (m/s): 24 Launch Stats: Max Altitude (m): 26 Max Velocity (m/s): 17 This is my data.  I, like Emily, decided to only change one factor at a time.  The factor that i decided to change was the number of fins. When i had less fins, it made the rocket lighter.  This made the rocket go higher and faster then the rocket with 4 fins.  From this data, i have concluded that Emily and i should use not 4, but 3 fins.
