Thanks

but it isn't enough useful.

Hello,

The vertical takeoff and landing planes(VTOL) use completely or mainly the propulsion system for the control of attitude and of trajectory, It is thus necessary to control the aircraft attitude  and the trajectory, in the case of the longitudinal movement, it thus should be used another thing that the RHP, or aerodynamics, ineffective at low air speed.

One of the solutions of topicality is control by vectoring thrust, or jet control surfaces or devices (nozzles or jet activated flaps) far from gravity center which creates an effective moment forces to control pitch roll and yaw moments.  This efficiency is needed at low air speed to avoid lost control or spin departures.  

For VTOL or STOVL  it is thrust vectoring, well go and read articles on Harrier jump jet. Another solution is rotor tilting go and read artcles on Osprey Tilt rotor

Thanks for all the attention.
