Use MATLAB to upload the Mars Ingenuity Helicopter Sound, which can be

downloaded from the following NASA web$-$site:

Listen to NASA's Ingenuity Mars Helicopter in Flight $$ NASA Mars Exploration

See the provided MATLAB starter code in order upload and to clip this file to a shorter,

more manageable length.

b$)$ Your primary goal is to verify that the frequency of the periodic humtype sound created by the helicopter blades is the frequency provided

in the above NASA link. You will do so by doing a basic spectral

analysis in MATLAB using the fft$.$

c$)$ Your secondary goal is to convert the periodic sound frequency in Hz

$($cycles per second$)$ to rpms $($revolution per minutes$)$ and verify against

NASA information.

d$)$ Both, the obtained frequency of the hum$-$type sound and rotor revolutions

per minutes $($rpms$)$ should be consistent with the NASA web$-$page.

e$)$ When converting from Hz to rpms note that the Helicopter has two blades.

f$)$ Compare the revolutions per minutes $($rpms$)$ of the Mars Ingenuity

Helicopter with the average rpms of earth helicopters. Why there is

such a difference?

g$)$ Produce a Technical Report

h$)$ Include MATLAB Code pasted in your Technical Report as well as a separate m$-$file.

i$)$ You code should be well commented where each line of code can be understood and

has some rationale.

j$)$ Turn in your project by the due date in a zip$-$file that includes the Technical Report,

MATLAB m$-$files.

k$)$ Send an email with questions about the project if needed.

l$)$ I will be available in Gather $($video conf$)$ on Thursdays Jan $19,$ Feb $1$ and Feb $8$ from

$4$:$30$ to $6$:$30$pm$.$ Email me first if you need to meet me on those dates $($other hours

by appointment$).$
