Why are Vx and Vy Different?!?!?!

In this video we talk about why Vx and Vy are different speeds from a power and thrust prospective.
If you prefer reading, cehck out this article, where I took all my information anyway.

@Merryfaceaviation , brilliant explanation! Could you please do one on Vmd vs Vmp as well, in the context of Max range vs. Max endurance please?

[@stenya]

I have a very simple (I think) explanation if somebody has a minimal interest in car can understand: Vx is torque Vy is horsepower Vx aka torque needs if you want to tow a caravan to the hill. (Steep climb, Vx, slow but steep, like a tractor) Vy aka horsepower needs if you want to go fast on highway. (accelerate, need to cover horizontal distance fast, Vy) The rest is magic with those charts ;)

[@rudyhiller]

This is a great way to explain it. So does changing the pitch of the propeller blade change Vx? Seems it would

[@lassefaugstad8223]

Thanks man! Best video I've seen so far on why excess thrust and excess power are different!

[@MerryfaceAviation]

thanks for the kind words!

[@NhanNguyen-vq3kr]

Wonderful. Thank you so much

[@MDRedwood]

Great stuff, thanks!

[@Stefan-nt3zk]

OMG! You might just saved my day! Best explanation ever! Thank you so much!! And please keep up this excellent explanations!

[@MerryfaceAviation]

Glad it helped!

[@steffenleo5997]

Well explained....thank you..... Left of the minimum if i reduce thrust(throttle down Power) speed increased and right of minima if i increased thrust(throttle up) speed increased, is that right?

[@MerryfaceAviation]

I'm afraid not! Left of the minimum you'll slow down quicker the slower you go.

[@yongah1]

At 4:43 you have Vx as best RATE of climb...is Vx not best angle of climb?

[@AlanTheBest97]

I have one question. Is it correct to say that VX would indeed be correlated to Vmd (The velocity where you have minimum drag or green doy speed)? Because the jet engine thrust avaliable remains quasi constant no matter the airspeed?

[@MerryfaceAviation]

Excellent question! I have to admit I don't remember the answer, especially as this video is mainly focused on prop aircraft.

[@nghicks42]

I think Nike calls it the “Swoosh.”

[@dumbdumb9394]

You try to give the video more brightness it will be great if you do

[@MerryfaceAviation]

what do you mean?

[@MDRedwood]

At 7:22 you said Vx by mistake. I think you meant Vy.

[@MerryfaceAviation]

indeed!

[@bellaaneke]

Thought it was just me😮

[@flyguy1637]

Yes u did.
