Delta wing manoeuverability

[FGR.4]

Hi.

Does anyone know how tailless delta wing aircraft like the Typhoon pitch and roll? I don’t understand as there aren’t any (obvious) ailerons.

[Wissam24]

They have control surfaces at the trailing edge of the wing, sometimes split but working as both elevators and ailerons.

[FGR.4]

Ah, right. Thanks.

Known as elevons if i can remember my aerodynamics module correctly

Typhoons actually have Flaperons. They combine the function of a flap, aileron and elevator into one. The foreplanes on typhoons will also provide some pitch input.

...The fireplaces on typhoons...

Don't you just love auto-spell...?

I thought it was a quaint term for the engines and wondered if they'd introduced thrust vectoring!

These are called canards.

These are called canards.

They’re called flaperons, the canards are at the front of the aircraft.

I was posting about the bits that

also provide some pitch input.

The "also" should indicate that it is not about the flaperons (as those were discussed earlier in the thread).

Quoting the message you’re referring to would provide some clarity.

I remember a very young Wissam24 on CCF camp asking an RAF person who was teaching our group about flight and how aeroplanes fly, and I asked her what a flaperon was, a term I'd heard somewhere, and she had never heard the term before. I was quite disappointed actually. Fortunately, one of the other RAF people came up to me after and told me. She seemed much more knowledgeable, actually, I'm not sure why she wasn't teaching us.

I’m assuming they were referring to fireplaces, which presumably is an autocorrect of foreplanes, which of course are canards.

[JetMan]

Autocorrect really is a curse sometimes - Fireplaces should indeed read foreplanes... That’ll teach me to read my posts properly!!

Foreplanes and canards are not the same thing though. Many use the words interchangeable (or just use canards as that’s the more we’ll known term) but foreplanes will only move together whereas canards can move independently of each other.

Typhoons have foreplanes as they can’t operate independently and, for example, rafales have canards.

[GertrudetheMerciless]

A foreplane is any wing like structure ahead of the wing/at the front end of the aircraft...

...so a canard is a foreplane. Always has been. The Eurofighter has canards. It has nothing to do with how they operate, because a canard is a foreplane.

[Harvo266]

Canards move together i.e. can't move individually, Foreplanes do move individually (the left can pitch differently to the right and vice versa)..

[Seahornet]

I agree with Gertrude; the formal name for such a flying surface is foreplane, whilst 'canard' is a less formal term for the same thing (a contraction of 'canard foreplane'). The spurious distinction between the two, based on whether they are fully independent or not, is a recent development, which seems to have the hallmarks of an urban myth - especially as the proponents of the idea can't agree which way round it is...

Can we not just call them "little wing thingys" for utter simplicity

[CJS]

canard

noun
1.
an unfounded rumour or story.

I first came across the term 'flapperon' at RIAT 1998 when Mike Whitehouse was delivering commentary on what I believe to have been an F-16 doing a high-alpha pass.

Somehow, 'flapperon' just sounds a little twee and unofficial!

Yep.
