hi hi
I'm curious as to what other people think T Birds are like. I have heard a lot of different, sometimes conflicting explanations for what they are and how they work. Some people say they work like the ekranoplan and utilize surface effect, but are otherwise essentially tanks. Other people say they are more like VTOL jets planes with heavier armor and weapons. Some people say they are like just like extra powered hovercraft.
I have no idea what they are actually like now. None of the 4th edition books seem to be of any help, they just sort of assume that you already know what they are because they've been around so long. Any clues?

Definitely not ekranoplanes, although SR *should* have those.

For me, I always thought they were VTOL 'tanks' with lifting bodies; not real airplanes, but stubby and aerodynamic vec-thrust craft.

You can have variants that would have ground skirts ala hovercraft,
Mostly they are ground effect vehicles and it looks like they typically have the the lift for low altitude flight.

-- What DireRadiant said. Think of a Harrier with more armor and stubbier wings.
-- They don't make a lot of sense in their supposed niche, but that's because they were directly cribbed from the novel
Hardwired (which is also where their original name came from, panzers). Which is funny, because in the
Cyberpunk sourcebook that Walter John Williams himself wrote, they look more like air cushion vehicles

Well, if they have high stall speeds, they're not really VTOL after all, right? Hmm.

Well, if they have vectored thrusters and small wings, they might need high stall speed when the thrusters are horizontal, but when put to vertical position they can stay immobile in the air.

Wait, they used to be vector thrust vehicles! When was that changed?

Something like
this, but limited in altitude due to it's heavy armor.

-- Hmm yeah that is odd. Because this implies that they need to land and take-off like a conventional aircraft. This is directly counter both to their supposed utility and the art (they are already borderline aerodynamically impossible anyways, with their turrets).

I'm fine with VTOL up, then swivel the nozzles to be a rocket-plane. They don't really seem to use ground effect, though. That's *really* low. Or, rather, if they use ground effect, they certainly don't *rely* on it, like an ekranoplane.

I'd say T-birds are supersonic vector thrust powered veicals that can make use of ground effect for long trips to cut fuel use.

Supersonic and tiny wings? Can't imagine them carrying enough fuel for any trip to be a long one.

Jun 19 2010, 11:39 PM
well they can hit 333.3M/S as a cruseing speed. Thats just shy of mach 1 at 340.29 m / s so with pilot tests It looks like one can hit at least mach 1.
Yerameyahu
Jun 19 2010, 11:46 PM
Daylen, there's certainly a sweet spot in play.

My point is that the F-22 is one thing, a T-bird is another. A rocket plane can definitely *go* that fast… it just can't make any 'long' trips.

In previous editions, LAVs and T-birds were synonymous.
There are at least 2 LAVs pictured on p113 of Arsenal.
The GMC Banshee seems like it's the odd duck being specifically called a thunderbird.
Yerameyahu
Jun 19 2010, 11:54 PM
Wait, are they *not* synonymous now? :/
To me, the Skraacha looks like a hovertank, not a rocket-plane. Hrm. The MiG-67 is a little faster, and the Banshee's faster still (a little). I guess it's a broad category?

I would imagine they resemble
Deep Flight, only with more bulk and four thrust vectors instead of the two propellers.
Dumori
Jun 20 2010, 12:00 AM
Hence my superstition of for long journeys it uses ground effect. As to reach mach 1+ it needs a pilot test so its not with in normal operation. Though with some mods to the base craft it becomes much more possible. I see the T-Bird as a class of heavy fast craft. With roles from fast transport. To HTR and purely fire-support.
Likely with radically different moderations. As a pure gunship it would be as fast a some jets but as versatile as a helicopter with VTOL and hovering. Though air superiority fighters and such would still have jobs.
The only fighter in SR4 atm the Federated-Boeing Eagle-C though falls as a T-Bird in this out look in a way. While more a harrier in style its body and such put in the same class as the GMC Banshee. Though one must ask why one has sensor 5 and the other 3. In fact costing almost a third of the price its odd that the only sensor 5 is the GMC Banshee.
Yerameyahu
Jun 20 2010, 12:00 AM
I guess, but the problem is that they don't appear to. That looks like a standard cruise missile, but the images we have of T-birds are *much* bulkier. They barely have any fins at all, let alone wings.
Some images
HERE are also illustrative.
Honestly, the Eagle-C's stats must be wrong, in comparison to the Banshee. It doesn't really make sense for a t-bird to be as fast as a fighter, even a VSTOL fighter-bomber.

Well ture. T-Birds are really named for there sound... and yes the images we have are mad. Did SR find a way to negate gravity a bit or such. Though maybe they use lighter that air tech to make them as "light" as possible so they need less lift....

-- The Banshee is still vectored thrust according to SR4A (p. 349). It's also controlled using the VTOL/VSTOL skill.
QUOTE
GMC Banshee: This light t-bird vectored-thrust craft was designed for reconnaissance and courier duty.
--I'm not sure what to make the Arsenal text. Perhaps it was a bit too off-the-cuff? But it's not like stall speeds are really given any explanatory text anyways

Shadowrun does appear to be a bit inconsistent with panzers though, in the original Rigger Black Book they are "Effective VSTOL (vector thrust)"
-- Rigger 3 I think had the best description of how these worked, and they should probably just have stolen that text verbatim: (See
Rigger 3, p. 69).
[ Spoiler ]
I find it a bit amusing that the Banshee can accelerate at 8.5G's with no obvious problems. In comparison, the Space Shuttle has a max G load of 3Gs during launch. 8.5G is at the
upper limit of humans in best possible conditions sustaining without
blacking out in a straight run. Or maybe I did the math wrong or something

Yerameyahu
Jun 20 2010, 12:13 AM
Anyway, the point is that being the fastest thing is *not* what T-birds are for. They're much, much slower than a jet fighter, even by 2010 standards. Instead, they have heavy armor/armament/payload, and they fly very low. Vectored-thrust makes sense.
Let's ignore the stall speed thing.

Maybe it simply refers to their gliding ability (nonexistent), as someone implied above.

It's called aerofoil hull design. The X-43 takes the design the concept to the extreme to achieve hypersonic flight, but at less extreme levels it makes a winless aircraft possible as long as it can maintain a fairly high speed.
Am I the only one who felt R3's vehicle rules were the best so far (aside from body)?
Yerameyahu
Jun 20 2010, 12:20 AM
I did love Rigger 3, so much. Anyway, for those without the benefit, here's Rigger 3, p.108:
QUOTE
Thunderbirds have stubby auxiliary wings and rely almost entirely on jet propulsion to provide lift and thrust. Without adequate power, t-birds become flying (or more precisely, falling bricks). Consequently, thunderbirds generally have short ranges and tremendous fuel requirements.
In most militaries, thunderbirds are used for short-range close air support, as well as armor support in terrain not suited to tank maneuvers. In these applications, t-birds are heavily armored and fitted with machine guns and assault cannons in place of rockets and missiles.
Sounds perfect to me: *short* range, gas guzzler, no wings, 100% jet thrust. They're hovertanks. Well. Flying tanks, because armored hovercraft also exist.

Add some gun turrets and you've got a GMC Banshee.

I'm rereading the original Secrets of Power novel at the moment, and there's a T-Bird in there. It's very specifically referred to as a Tank and a Panzer... I suspect that they've kinda morphed and been retconned a bit over the years...
The original Rigger Black Book had a pic of one too, IIRC>..

Hypersonic is not within the scope of a t-bird. Supersonic is barely okay, as an extreme maneuver, for the exceptionally aerodynamic models.
Dumori
Jun 20 2010, 01:04 AM
Very much so as I stated or at least tryed. Though the Federated-Boeing Eagle-C can cruse at mach 1.175. Though its T-bird staus is debate able but looking at its over stats it fits very well as a mill spec combat t-bird.
Daylen
Jun 20 2010, 01:43 AM
they are the SR version of the A10.
Yerameyahu
Jun 20 2010, 02:00 AM
Agreed. It's much too slow for a F-15, or even a Harrier. It's not too slow for an A-10, and it doesn't look like/isn't described as a T-bird or LAV. It's just a really slow fighter-bomber.

So basically T Birds can only really be used over water because they wont be able to fly over things like trees due to the limitations of Ground Effect. I guess that works too.
Yerameyahu
Jun 20 2010, 04:09 AM
No, that's the whole point. Ekranoplanes fit that description, but t-birds certainly do not. They're explicitly described as 'used on land where tanks wouldn't work'.
I'm not convinced ground effect/WIG has any significant role in t-birds. AFAIK, you need *wings*, the bigger the better. Hence, the ekranoplane. T-birds, on the other hand, are drawn and described as flying bricks.

If one of those ekranoplanes used something like a GEnx with thrust vectoring nozzles and a NOE pilot assist system, it would have no difficulty flying anywhere in the world. However, since they use engines that barely put out 5% of the thrust, and manual flight controls with only a very basic autopilot they are limitted to oceanic flight.

• Panzers (yes, I use the old SR1 term because it sounds cooler) probably have a
lifting body hull which will provide a bit more lift than their stubby little wings alone will.
• They may also benefit a bit from the
wing-in-ground effect in some situations, just like any other aircraft (which will substantially increase their fuel efficiency, as previously noted).
•They probably are not normally VTOL, and as described in previous sourcebooks are VSTOL so they don't blow all their fuel just getting off the ground.
• Being below a panzer is very hazardous to your health.
* They will require some sort of prepared ground to land on and take-off from.
Deadmannumberone
Jun 20 2010, 04:35 AM
Technological advancements allow for extraneous components to be removed. Remove the wings from an ekranoplanes, and install thrust vectoring nozzles controlled by a NOE system on the back of a powerful set of engines and they'd still be able to fly.
Yerameyahu
Jun 20 2010, 04:46 AM
