Difference of Helicopter, Airplane and a Drone

Last night I learned some basics of aerodynamics in a very fascinating way of how the mind can imagine.

After reading through the summary, make sure you watch the bonus video in an attempt to solidify your thoughts on the difference of how mechanically made flying objects such as airplanes, helicopters and drones could defy gravity.

So normally in order to make something fly, you need something called lift. 

Of Airplanes...

Lift is a force that counteracts gravity - it's why planes need wings to take off and stay airborne. Without wings they're just really fast buses. The wings, and the general shape of the plane, defines how aerodynamic it is - how easy it is for it to go fast, basically. By going fast, the airplane generates a steady stream of air for the wing to slice through. This is how lift is generated. It's why airplanes can't just stop in the middle of the air, and also why even if both engines die the plane can continue flying for some amount of time - it still has some speed remaining, and until that speed goes below a certain threshold (known as a stall), the wings will continue generating lift and keeping the plane up. 

 

Of Helicopters...

In contrast, helicopters don't really generate lift as much as they generate thrust. Missiles and space ships work in the same way. They simply produce a force that moves them in a certain direction - whether that's up, or sideways, or down, or whatever. If that force is strong enough to counteract gravity and air resistance, it can move wherever it wants. Think of it like letting go of a blown up balloon - it has no wings or engines, but it still moves really fast in all sorts of ways.

 

Of Drones and Quadcopters... 

Quadcopters are basically helicopters, but now there's 4 rotors (hence quad). Thus, they can do everything helicopters can do, in even crazier and faster ways.

Here's the video...

Two Years Wasted

Love story inside a story... hear this out readers.




It's actually a true story...
It hurts to talk about it
But wanna know the funny part that's not very funny to me?

She was cheating on me the whole time
(Sighs)
If I had put the some amount of time i spent focusing on some girl into my degree,
I would have had much better grades and more money to show for it
But no!
I got f*cked

Two Years wasted...

I was making good money as well i could have bought a new car
and have afforded a new apartment closer to the city
But no!
I let what appeared to be true love screw me
I just lusted after her like some pathetic loser
While she took my money and spent in on vacations with her other guy
while i thought she was away on work trips
I'm so broke because of her
I would have been well off
No I'm still in school finishing my specialist degree

My only advice - never trust anyone
Not even your family
Be competent
Then you'll never have to rely on anyone
or anything to make you happy
She may have broken my heart but she'll never take my pride
Sure thing

I really sought revenge, I did
I had it planned out for months
But then i let go
I let go of my hatred for what she did to me




Straight from the heart,

Hongkong Crisis - It Now Involved Terrorism

5-minute read


There are other things to worry in our country but i couldn’t help to be disheartened on the current crisis that Hongkongers (citizens) are going through.  The account of real time danger they are having now is harrowing; that even with the coldest of hearts could fall into unspeakable surprise by how the authorities are treating these citizens.

Here’s a graphical description of how they are terrorized. A picturesque of suffering, pain and pleadings of mercy especially when the OP (original poster) mentioned that these innocent folks who were not rallying/protesting knelt and beg the assaulters to stop.

This reddit post reflects a raw, unfiltered experience of a Hongkong Citizen; trying to voice the severe condition they are in and at the same time, trying to move the reader to at least do something in any way they can to appease and help their current situation.

I chose to post this in my blog because it feels that i am obligated upon my knowledge of this piece of truth to share to my audience no matter how big or small my followers are that somehow somewhere, a part of a nation in this earth is at a stake of difficult time. A state that life and death are the major players bestowed to each individual. Where no one can tell that any moment, any second, their lives have been or spared or they have already breathed their last.
