The original delta Mirage was designed as an interceptor, basically to get there as soon as possible and try to stop a threat such as a nuclear bomber. Speed was important above all else (except of course having enough stability to fly, where deltas also excel). Canards are added for maneuverability for use as a point defender. As range is not critical for ...

There is not one problem with the canard layout but a whole rag-bag of problems. Firstly, it is worth noting that the reason the Wrights built their first Flyers as canards was to make them deliberately unstable. They believed that a plane could not be both stable and controllable; a stable plane would just settle on its course and it would be difficult to ...

In airplane empennage design, there is a thing called Tail Volume Coefficient. Mind you, there are no volumes here, but you are working with $m^3/m^3$. It is calculated as follows: Horizontal tail volume: $V_{HT} = \cfrac{ l_{HT} \cdot S_{HT} }{ c_{REF} \cdot S_{REF} }$ Vertical tail volume: $V_{VT} = \cfrac{ l_{VT} \cdot S_{VT} }{ b_{REF} \cdot S_{REF} }$ ...

Canard designs shouldn't be summarily classified as "failures" without understanding the entire design of the aircraft. In the age old struggle of maneuverability vs stability they provide a very useful tool in decreasing excessive pitch stability of delta type aircraft. In the case of the Viggen, they also enhanced high AoA lift for STOL while ...

I wonder if this might have been an actual Diamond Hybrid -- a combustion/electric hybrid aircraft (hence strange engine sound -- the propellers are driven by electric motors). The two electric motor nacelles (each holding an electric motor, batteries, and inverter) are mounted on a "canard" type surface (which doesn't appear to have any control ...
