L-39 Albatros

[W5]

[quote="Yoyoma"]Well gents, here is another cool toy that is becoming more and more popular in North America.



If I had some spare dough, that's what I would get!! And it's a Twin!!"




Thanks for the pic.,and the link Yoyoma. It brought back quite a few memories, as I did some training on that particular a/c and lots more on type at Brustem, Belgium.

Doesn't the L39 require a G-Suit?

No. It doesn't produce enough thrust to overcome the large amount
of drag which is a consequence of the production of large amounts
of lift, which is where G comes from.

The Cd curve is exponential wrt AOA, after all.

Executive summary: get an afterburner, then think about a G-suit.

Again, people who don't know very much about aviation think a G-suit
is a magic bullet or something, when in fact it might increase your G
tolerance maybe 1.5 G's. Technique is far more important.

Hate to do it, but I have to call you on this one. A G-suit is not intended to increase G tolerence over a short period of time. Infact, aerobat pilots without G-suits pull upwards of 12G while a fighter pilot in combat may see only 9. The difference is how long the G is sustained. Pulling a plane through an aerobat sequence is a far cry from sustained turns in a fighter.
An extra 300 probably doesn't have the power to sustain a high G turn as long as an F-18 can...
The albatross was designed as a fighter trainer was it not? So training with suits is important, even if the aircraft doesn't reall need it. G-suits may be usless for aerobat, but that's not what they're for.

Here's what a friend of mine who competed in aerobat had to say about it:

The guys who fly unlimited category maneuvers will be total +14 / -14 depending on the maneuver. sustained, maybe +6 for 5-8 seconds, etc....but keep in mind too, that you will always be going +14 to - 14 spread (or 28g's) in the span of anywhere from 4 - 10 seconds, thats what really kills you. And that in itself without a g-suit is impressive takes a bit a time to be able to do....on occasion, you get down with bruises on your body form the straps....
g suits only exist to sustain VERY long g's...as in more than 10-15 seconds..other than that, they are more or less useless....(well, useless for their weight to the aircraft and cost).

By the way, Canada has developed tha most advanced G-suit in the world (unless there is some russian job I haven't heard of) so be proud, we still invent cool stuff every once in a while.

I'd way prefer the SU-27. Though the su-27 would probably have me barfing all over myself within 30 sec.

su-27 woud be a close second for sure. sexy aircraft indeed.

something about mach 2.5 and FL800 though in a cold war legend..

HZ2P this is for you and it's probably been posted before, whatever:

The MENSA Troll

The MENSA Troll shares many characteristics of The Flamethrower Clone, but this style of poster refrains from writing as many blatant homosexual overtones. The general gist of all the MENSA Trolls' posts should hint at the idea that the MENSA Troll is the smartest creature in the world, and every time he posts a message, it is for the sole purpose of manipulating others on the forum. It doesn't matter what reaction he gets from anything he writes because the MENSA Troll can justify anything he wants. If, for some reason he is not able to justify it, he should ignore it completely and avoid the subject. Under NO circumstances should the MENSA Troll respond to anybody's criticisms of him; he should instead continue to criticize everybody else and avoid engaging in a two-way conversation.

EXAMPLES. The MENSA Troll will post the following messages:

Counter-Strike forum: "It's interesting to see so many of you silly little monkeys jump around and react to my post which created the associative link between Counter-Strike players and certain members of the canine family. Your predictable reactions are exactly what I expected from such a lowbrow, intellectually dead race of Neanderthals who barely possess the ability to use primitive tools. I'm sure it will take you months before your ape-like brains are able to realize that the sniper rifles in v1.0 are shit. Go back to downloading those mp3s you heard on the radio and watching ABC, you pop-culture addicted maggots."

Star Trek forums: "It is apparent that many of you lack the ability to comprehend a single one of my posts. If you did, you would understand that you are all pawns on a chessboard I bought and own. You are all merely dancing chimps here to amuse me, and I have the ability to pull your strings and control your every move. If your reactions weren't so banal and tedious, I might be impressed."

Honda Civic forum: "You mindless drones will purchase whatever product is placed before your ignorant, easily influenced heads. You are so willing to be manipulated by other people, it is no wonder I am able to bend and shape you into any way I please. Besides, it's common knowledge that the CRX is by far a better deal."

A G-suit is not intended to increase G tolerence over a short period of time.

Right, that's what I said. The L-39 doesn't have enough thrust to
maintain the sustained G.

An extra 300 probably doesn't have the power to sustain a high G turn as long as an F-18 can...

Obviously. That was my point about the L-39 - it doesn't have very
much thrust, either, making a G suit unnecessary.

Honestly, the reading comprehension skills of most pilots are so dreadful, it's amazing any instrument approaches get flown correctly.

Ok, perhaps I didn't understand what you wrote. But my comprehension is based on your composition, therefore I think we can agree that the commercialization of Christmas is, at best, a mixed blessing.

The last paragraph you wrote in the original post seemed to insinuate that G-suits were useless. I was simply pointing out that even if it wasn't necessary in the L-39 a system might be installed for training purposes. Since it seems that we agree I would like to suggest another beer is an order...

That's amazing W5! What a treat this must have been! I was promised a ride in one of the few remaining Fouga's in France or the PAF's Alpha Jet if the fouga wasn't ready but they never were able to clear me for a flight! I stayed on the ground and watched them perform!
