DCS: Air Density Vs. Missile Energy. 

Hey guys, just some real basic concepts here, nothing too complicated. just a side note, if the opponent does the same you did (drags the missile down) whoever recommits and fires again will usually win. so keep ur head in the fight. good luck and thanks for all ur support on the channel. its been an amazing few months seeing it grow. thank you guys.

i dont even play dcs and i really like your videos, it's just always interesting.

I work as an aircraft engineer. And holy moly i didnt expect dcs to even have physics for missile performance under different heights. This is amazing. I remember using simple dodge mechanics in F-22 lightning 3.. Ancient but good game at its time.. obviously it didnt have the mechanics but if you wanted to dodge you had to make the missile turn so bad that it would lose energy and miss. Good vid.

I always thought that by pulling down from a higher altitude you might increase the chance of getting hit by the missile. I didn't thought of the fact that increased density would slow down the missile. But now I know that i was wrong. Thank you @GS.

Best DCS channel! I do always learn a lot. Thank you GS!!!

Your channel is truly an encyclopedia with a lot of timeless gems like this one

Once I played LockOn Flanker 1.0 on Win95/98 for many years. But now I have no time for that. thats why I watch your videos.

Awesome video showing air density effects on missiles...kudos also to whoever made that missile chart!

Great video man! As always, quality delivered. I’m surprised about the amount of content this channel has. I never loose interest. 👍🏻👍🏻👍🏻 hope the channel grows.

All this info it's great helps to learn to fly and also learn to fight; clean and clear, i like it.

Neat transition to the Tac View segment man, good stuff

Physics fact of the day: In the absence of any external forces and provided your already on a heading towards your target then yes a straight line would be the quickest way between 2 points along with being the shortest distance. However when external forces get involved and when you start out moving on a different heading than your target the brachistochrone will always be the quickest way between 2 points with no exceptions. Keep up the good work though I love watching these videos.

I think your videos are amazing. No BS, great explanation & interesting stuff.

Hi Buddy ! That was sweet tach on Basic Concepts and this is the way win Dogfights. Thank for super video...

Very nice and detailed explanation there GS, this is refreshing my tactics/understanding, GR8 job there on the TacView M8!, love your vids!, I find myself going through the older ones as well, plz keep it up M8!! :)

Great video! Also I know I've been late to mention this, but this new microphone that you are using is great! Cheers! Favorite DCS channel btw, I learn a lot from your explanations.

Is the gravity pull effect involved - or it has the coffee break? They both fired a missile almost in the same time, ok? Aim-120 that goes up gain more energy than the diving one???? Following that logic - all object coming from above must decelerate because of the air density. Especially small and aerodynamic objects. Of course the air cause drag but gravity pull should have more impact on the object than air density. The higher you fired the missile the further it should go and the higher pk In the video above it works just opposite

Very nice video again. One thing crosses my mind though. You not only led this fox to the dense air but also increased the distance by coming down thus the missile had to travel more and more into denser environment with every feet it flew down. BTW. From what I see that the gain from using G to propel the missile it's not that significant to overcome fraction forces in a denser environment. Anyway it's indeed a good video - thanks for it :)

Cool idea to use thicker air density to drastically shorten a missile's effective range.

Nice man, very informative again going to try some of this stuff out with the F18. I bought my new laptop yesty and she eats DCS get 130fps at Alt and 70-90 low.. I train up with the F18 and see you in the Sky Soon !!! 👍 10/10

The physics of all of this are about to change! DCS announced big missile fix!

you could be a great teacher for fighter pilots right. wow thanks, that was interesting.

thanks for sharing tactical attack and defense Information

such great information keep up the good work....!!!!!!

Nice video! Now I see why you go inverted before firing - so you can just drop towards the ground.

Is their any reason why you inverted when you fired your missile

This begs a question I've been thinking of since I've watched some of your BVR fights: since DCS obviously takes air pressure vs altitude into account, does the Mach number also factor in air density, considering sound travels faster at sea level than it does at altitude?

Wow man I never would have thought that… I thought pulling the missile down would help it gain speed… cool

id also add putting the missile to 90 degrees (3 or 9 oclock) and affording myself a bit shallower dive (70-80 °), think that would bleed even more energy off the missle, since it will have to turn on two axes, spendin some extra energy on vertical axis turn. right? :)

When you released your missile and rolled towards the ground, you lost your lock. Had it gone pit bull straight off the rail?

I would never think that, missiles being much faster than their terminal velocity, they would loose energy by diving, drag being worse than the potential energy they convert to speed, while it seems quite obvious and common sense. Feeling pretty dumb right now.

Dude. You have some real understanding of balistic flight dynamics and energy conservation. Generally speaking, you have an amazing grasp on modern aerial tactics... Where did you learn this? Sim iterations?

Nice!!! I might download it today. I need to start practicing

Hi there! I'm loving your videos man, they got me to seriously go back to DCS and actually try to learn it (it'd been sitting in my Steam library forever). Anyway, here's my question for you: this type of tactic works great when using Fox-3 type missiles, but what if you're only equipped with Fox-1 and 2's? (i.e. the S530 and Magic II from the Mirage 2000C) I feel like I'm hugely outgunned whenever I fly that plane, but God knows I won't stop using it..! Thanks for your work!

Nice vid GS, love it.

This still applies to Over G fighters- an Xbox 360 game from 2006 :P

Are there tables that show missile max G? There should be turn performance tables for certain altitudes and missile models. I have some older books but they don’t publish this data.

"Jeest".. a gamer... a really smart guy

Woow, another one. Ur video was Helpful & @least Entertaining, cheers.

Awesome vids dude

Thanks for the info. I'm planning on buying my first DCS module when they go on sale. The only thing I'm worried about atm is DCS world is frequently crashing during loading and when in flight is dropping frames frequently.

Damn never knew there were so many calculations and effects with missiles. I always thought they were heat seekers or active radar like in battlefield 4 and all you had to do was pop flare to avoid being hit or turn on after burner and head down to out run the missile.

Well done as usual!

What's the point where an air fight goes from a fight against the enemy missiles (in terms of energy/manouvering) to a fight against the enemy fighter? Isn't the fighter that has more height and speed at about 13:00 in a better position to recommit? It comes always down to 'chance of missile evasion' vs. 'time, energy, and chance to commit to the next offensive manouvre', doesn't it? For that reason, an F-Pole or Beam would be superiour to air-to-air-missile anti-energy manouvering, especially if you don't have any Fox 3s to force the enemy into a defensive manouver (That's the reason M2000c against the major FC3 fighters is so challenging).

Great video. awesome.

Nice explained !

Thank you very good, much appreciated. Good explanations. Hard to see in the video but when you did fire your shot, were you close enough that you didn't have to wait for it to go pitbull before you went down ?

And those armchair generals say whoever fires first wins, and a missile on it's way is a 100% hit/kill....

Interesting. So that’s why phoenix missles go high i guess.

Could you do a video for these instruments on your cockpit? I want to learn in depth on what these shapes mean or what even is the radar at this point

Entertaining and helpful

Can anyone post that graph about missile effective range, would be very gratefull. Great video,as always!

Every time I decide to watch one of your excellent videos, my first gut reaction is to switch to a Fox3 so I don't have to listen to your growl.

Great video!

Great lesson!!!!! Thanks

Good stuff!

Im thinking about getting into dcs. Does this game have tutorials to teach you all this stuff. It seem a bit overwhelming

But when the missile goes down line that, even though it's entering more dense air, does it gain an energy advantage due to gravity pulling it down?

awesome tuto thx! could you please explain and demonstrate the differences between the Amraam and Sidewinders variants (AIM120 B/C & AIM9 M/L/P available in DCS) that would be helpful thanks! :)

What is the purpose of inverting before firing?

Ackchyually. You never fire standalone missile. It's always a salvo with sound interval, to counter basic maneuvers and harass adversary.

Im sub you because i liked your gameplay, tactics, and you give all important information about dogfigts, gun range, etc. Do you have a Tutorial Section? I played this game once but saldy i never understand it. Cheers ;)

great, thank u

There’s a website publicintelligence.net/u-s-navy-f-18-natops-flight-manuals/ that has the real flight manuals but when it comes to weapons systems the info is classified as you’d expect.

Going from high to low dont that increase the rockets speed as well just that it looses energy faster when it runs out of fuel?

Can anyone enlighten me on why does diving bleeds missile energy but on aircrafts, diving gives them more energy. Is it because of thrust?

Nice video! Would it be possible to do this while keeping radar lock and within effective missile range, perhaps to guide semi active missiles? Thanks!

Excellent video. Could a plane out of chaff decoy a radar homing missile by pickling the drop tanks at an interval?

This guy is a st8 up “G”

You‘re breaking lock at around 10.5 nm. Is this already within pitbull range? (Always thought it was at about 8nm)

Is there guesswork involved in when to go high again?

At one point in my life, I thought split-S spelled like split ass I want to get AIM120'ed

I think it would be really cool if you did a video of you in an F 14 vs a Saint Adversary vfc-13 😎. Top Gun? Never heard of him 😂😂😂

Do you wait until pitbull before turning down?

Spam chaff and make the missile recalculate its trajectory until its out of gas :)

Night gun battle?

Any info on beating Sam

Dark docs narrator vs this guy

The AI seems poor on his side, a human would have increased speed and put himself at a 90 degree angle to your missile maybe even try a 180 escape.

comfy

Only I know is that the first fired missile from long range (r-Max) are going to become garbage

I see a lot of people, mostly Americans, who seem to think modern air-to-air kills occur at 50 or 100 or 150 kilometers. This is possible but very misleading.

#science

You can't fire a missile while inverted

Your voice sounds like you have a little Canadian win you. lol

I'm astonished by how dumb is the AI. Turning straight into incoming Fox 3...really ??? At least in Falcon 4 they know how to pump !!!
