New Task

 

Wings

 

  • Seems we still need to figure out the proper wing span + chord length combination for ideal wing loading (~26 oz/ft^2?)

    • 58 oz/ft^2 with 5 ft wing span and 8in chord length

    • aim for high 20? ~35 is the heavier side

    • 4:1

    • standardize units - metric

    • m/s > km/h

    • use metric for wingspan moving fwd

    • specific numbers ~ a range

  • 8% camber airfoil isn’t standardized

    • find something within 6-10%

    • high camber = better lift at low speed

    • low camber = less drag

  • spread sheet calculator
