Solar Team Full-Scale 2017-2018 Spartan Superway: Week 8

For this week, solar team successfully calculated the power that is needed for the 9 m track. Since we are going to build 9 m long horizontal track, some of the values are changed to meet the requirements, especially the elevation force.

Changes:
elev_comp = 0 #(1/n_bar)*n_t*M_v*(g*z)
aux_comp = 0 #n_t*P_aux*t_s
M = 400 #(kg) Mass of fully loaded ATN vehicle
P_aux =0 # previous 3500.0 auxiliary power, W (see Wikipedia for auto air con)

V_l = 1.5 # line speed, m/s V_w = 1.5 # average wind speed, m/s

Result:

** Energy per vehicle **
Energy required, E(t_s) = 8.70e+02 J
Average trip time, 0.5 minutes
Average power, P_avg = 32 W

>> Energy per 150 vehicles <<
Energy required, E(t_s) = 1.305e+05 J
Average trip time, 0.5 minutes
Average power, P_avg = 4.73e+03 W

KE loss = 3.71e+02 J ---> 42.6%
Air drag loss = 2.26e+01 J ---> 2.6%
Rolling resistance loss = 4.77e+02 J ---> 54.8%
Aux power loss 0.00e+00 J ---> 0.0%

Based on the power was calculated below, there are some of possible solar panels that can be used for the full scale solar design.

Due to aesthetics we should use thin film:https://www.amazon.com/ALLPOWERS-Monocrystalline-Lightweight-Connector-Compatibility/dp/B07195WHHX/ref=sr_1_5?s=lawn-garden&ie=UTF8&qid=1508262264&sr=1-5&keywords=flexible+monocrystalline
