Can thrust vectoring be used to enable the use of flaps on canardless tailless delta-winged aircraft?

I'm considering flying wings as well as airplanes with only vertical stabilizer. I know that there is a destabilizing effect in place which is counteracted with some computer-aided control input on ...

Disadvantages of using thrust vectoring only in an aircraft with variable rotation nacelles such as the X-19

Take a quad tilt rotor aircraft such as the curtiss-wright X-19 or even a bi-tilt aircraft such as the V-22. What would be the advantages or disadvantages of using thrust vectoring only for control ...

Why do jets with 3-D thrust vectoring never hover nose up, but instead move slowly forward?

I've seen several impressive videos of fighter aircraft moving incredibly slowly by essentially hovering on the engines, balancing using thrust vectoring. For example: This Su-10 This Su-37 Large ...

How bad is the efficiency of jet engines under low loads?

VTOL operations need 4-5 times more thrust than a conventional take-off of an aircraft. If you don't want to install additional lift-engines into a hypothetical aircraft and use thrust vectoring to ...

Are wings any more efficient at creating lift, versus orienting the engine's thrust downwards?

As I understood from this article, wings on an airplane basically create lift by pushing air down. Maintaining the lift force expends energy because air needs to be continually accelerated downwards. ...

How is thrust vectoring controlled by the pilot?

Thrust vectoring is used to extend the manoeuvrability of aircraft outside a `normal' flight envelope, by providing (optionally differential) vectored engine thrust, as explored in many previous ...
