What is the point of designing canards with such deflections though? Would the plane ever achieve this kind of deflection in flight?

on the gripen are airbrakes, maybe the J-20 use them in the same way.
in flight not in that way

So...is the new engine the reason it has reportedly flown five times in two days?

Those of you knowledgeable in these things...is it normal to use two different types of engines on a prototype at the same time? Or is it most likely a different nozzle on the same type of engine? Why would one only use ONE of the new ones? If it was a new type of engine, perhaps more powerful, you couldn't use it fully as the other engine would lag behind....wouldn't it?

With a new engine on a twin engined plane, it is always safer to only install one new engine, especially for first flights.

This way if something really bad happens to the new engine, you always have a proven back up that should be able to get the bird back home safely even if the new engine suddenly fails during the test flight.

I am more interested to know what this new engine is. Surely it is too early for the WS15, but putting in a moderately improved WS10 seems like a bit of a wasted effort since anything other than the WS15 would just be a placeholder anyways.

Unless we hear about a major breakthrough with the WS15, I am more inclined to believe that this is just a new exhaust nozzle instead of a brand new engine. Maybe a TVC nozzle?

(Thanks Martian + HouShanghai for the link. :p .)


That's so strange too. Since the URL's look the same in both versions. Ah well.
