" Hover Velocity " _ Is there such a phenomenon?

[Snattlerake]

I was listening to something the other day either on TV or a podcast I can't remember which.

The person talking used the words Hover Velocity. In addition to this, can't remember the sentence or the context of the sentence.

I put it to you'se guys.

Does a helicopter in a hover have velocity?

FOR THIS QUESTION, the helicopter is not moving vertically, horizontally, or in any other direction relative to its' original hovering position.

Force Mass Gravity Air Distance Time
F=mhelicopterg
F=maira
mhelicopterg=maira

Velocity V=d/t

Acceleration is velocity per unit time, so a=v/t.
Helicopter - hel·i·cop·ter
/ˈheləˌkäptər/
Noun, a loose assemblage of aeronautical parts all moving in the same general direction.

Only if v can equal zero?

In that scenario it would have velocity relative to wind speed, but not to ground speed.

 

[sklfco]

The position it is hovering above is not a fixed position. The earth actually moves quite a bit.

In the real world, that hover isn't perfectly still, so there is some movement, and if there's movement, there's velocity. Also consider that it has to maintain enough lateral airspeed to keep its ground speed at zero, or it'll start moving with the wind. The rotor is also moving air to maintain lift, so it is maintaining a vertical airspeed. So, yeah, I'd say that a helicopter in hover actually has several velocity components, it just works out that they all balance each other out relative to the ground.

Doesn't matter. It's all politics.

I mean, technically, if the helicopter didn't have velocity in the upward direction it'd sure be falling fast to the crash site.

Well….. according to the last SH-3G Helicopter Crewman I spoke with (myself) we agreed on the answer and it is Yes, the ability to overcome the winds and other mechanical oddities there is a nice little device for the “Dry” crewman to hold the hover in place (as close as possible) using the “Hover Trim” handle located just forward of the cargo door on most helicopters where precise hover is required.

Are the propellers pushing down on the air or pulling up on the air?

It's Trump's fault.
