Description

Function to simulate the response (flight time) from the paper helicopter experiment, using a semi-physical model based on dimensional analysis

Usage

1
2
flighttime(w, r, t, d, theta0 = exp(0.102), theta1 = 1.9, phi = 0.1,
  int = 0)

Arguments

w

rotor width [0.03, 0.09]m

r

rotor length [0.07, 0.12]m

t

tail length [0.07, 0.12]m

d

paper density [0.06, 0.12] kgm^-2

phi

standard deviation of response distribution

Details

The flight time is simulated from a normal distribution with mean derived from a dimensional analysis regression model and standard deviation phi.

Other parameters (theta0, theta1 and int) are regression parameters.

Value

Simulated helicopter flight time (seconds)
