Iran Moves 35 Years Ahead by Reverse Engineering US RQ-170

stable or not, without AI or pilot commands to decrease the altitude, a drone would eventually enters stall state and would fall like a rock. in fact that picture proves that a pilot has landed the RQ-170 too.

that is not true, You need energy to keep flying.
Should that supply of energy stop ( from engine or air currents) you will loose altitude.
Gravity is every present, and you need to counter gravity to keep flying.
Loss of power does not mean the wing will stall. This is why I wanted you to pay attention the wing geometry.
stall characteristics are dependent on foil geometry, and then the wing's geometry.

Simple physics !

RQ-170 is a flying wing which is inherently as unstable as it get , you cut the power and it'll dive nose down and there will be no flying leaf
another flying wing is B2 that need 3 different computer work with each other just for stabilizing it , you cant compare these planes with glider like planes like what you showed

Ahan, is that true ?

Ever observed a bird and questioned yourself why has the bird evolved into a flying wing design ?

Instead of spending so much energy on the forum trying a defend a very difficult point, why don't you spend the same energy learning science ?

B2 RQ-170 need computer power to make them fly straight ahead.
 
so it looks like a lot of people dont have the tolerance of watching iran , achieve !!!

well they should close their eyes maybe that would help ;)

We are not talking about the exact copy of RQ-170 !

yeah , i heard we are even adding features that us was looking forward as their future plan ,like temp. control etc.

Why not Iran help a victim state of US drones.. and send some specialist hackers to Imran Khan, who will land US drones @ Peshawar airport and this way children lives will be saved, without shooting a bullet.

We can't share military secrets with pakistan ... & you know why !
 
It is not easy to reverse engineer, and Iranians obviously bullshiting, Iran can dismantle to parts but can it produce the parts? nope, the key here is the technology to produce parts.

We have 3D print ability !

let me make something clear for you ... there is no bullshiting or bluffing ... stuff is ready for first fly !
 
I wish you wouldn't publicly make a fool of yourself by accusing others of callousness and jingoism, while you yourself fail to properly look at an image you're referring to, to back up your claim.

It is very clear that the RQ-1 made a controlled landing and didn't fall out of the sky. You don't have to be Sherlock Holmes to notice the deployed and mangled landing gear, under the fuselage.

Well I'm not the one who is resorting to pointless attacks rather than being able to prove through technical terms they are right.
If there is deployed and mangled landing gear it could be of two reasons:

1. the Drone had a mechanism to lower gear at low altitude
2. There was a malfunction that resulted in the drone thinking it had to land and it did(This has happened before to a MQ-1)

time to time? really? instead of bringing a ridiculous example for a funny statement(survive intact after loss of control), show us a theory in which a tailless drone can fall down on enemy field intact.

possible theories:
engine failure( or loose of everything including engine):
stall is unavoidable, unless pilot or AI decided to give a gift to Iranian. in this case your example will be rejected cause that aircraft had a working engine (plus a pilot that keep it's balance, and his final act, ejecting caused enough thrust to avoid crashing)

communication loose:
drone will return to it's base, unless someone has already detected it and ambushed a GPS spoofing net for it.

control(hydrolic) failure:
drone will keep flying till ran out of fuel, stall would be unavoidable (again your example doesn't match cause that aircraft had a working engine.)
In none of the cases have you given solid counter examples. A loss of control does not entail an engine failure or otherwise.. Nor does it mean that the drone will always head to base. There are two examples of MQ-1 and MQ-9 systems going "rogue drone" in which they did not respond to operator inputs nor did they assume RTB programs in case communication was lost.

Moreover, your assertion that flying wings are unstable has nothing to do with their susceptibility to wing stalls. Infact, they are MUCH more susceptible to it as compared to conventional aircraft in both symettric and assymetric stall scenarios.

Your attempt to guide the conclusion to GPS-Spoofing is also tripping on the rug from published knowledge that Drones still essentially rely on Primary INS guidance with GPS correlation. These are based on tolerances that tell it what levels of difference between two data feeds is acceptable. So if the GPS said it was 500 km away from where its should be, even the most least sense programming would include a flag that would make the drone ignore GPS inputs and rely on INS. Such programming exists on even on smart phones with dual GPS/GLONASS systems. One would think the US defence industry knows better.

Especially airframes like of RQ-170 which resemble maple seed and prone to autorotation

It could be anything, perhaps the drone did decide to land when it ran out of fuel. But historical evidence indicates that in all these scenarios Drones tend to pitch down to blow themselves to pieces. A second thing ignored by the GPS spoofing landing claims forgets that if the drone landed in the area where they showed it being airlifted by the chopper.. it would not have been intact and rather have tumbled over and broken up in the terrian where its gears would have caught onto every other thing.
However, counting on jingoism.. we have certain releases that came out in the same vein as the esteemed members assertion.
Supposedly the drone made a perfect landing
Only later it dawned it was a different US drone under going testing in the California desert..

And if this screen grab is to be taken.. I dont see any gears there(although it looks like CGI)

oh jesus !!!:lol:

dont u think the possibility that iran hacked into the system is a little higher than that??

i even can believe that a pigeon has flown into the engine !! but this is sooo funny :P

Thermostats? :what:

no brah!! in our country people use thermostat as a temp sensing device , not a system which balances the temp of inside with that of outside !
