It is counter each other to push away, and continuation acceleration of taking advantage of a situation, the driven rotating rate of shaft for taking off turning moment driving output shaft is made more than master
It is dynamic to drive rotating rate of shaft, the left and right entirely dynamic aileron of VTOL fixed wing airplane further to adjust balance under the control of the computer
Aerodynamic condition, engagement sleeve are separated under airplane ascensional force effect into upper and lower two parts, and aircraft is taken advantage of a situation and taken off vertically, and depart from female
Warship.
Step 4, VTOL fixed wing airplane are rotated with itself, and the mode of vertical ascent rises to safe altitude,
Servomechanism is controlled by airborne computer, the pitch of the complete dynamic aileron in left and right is manipulated respectively, or is manipulated the inclined of complete dynamic vertical tail
Gyration, realizes that VTOL fixed wing airplane is realized from rotary motion flying to tapered auger line moving the transformation of flight,
The resultant motion of the linear motion that the circular flight motion that i.e. three dimensions inside radius becomes larger is gradually increasing with height.
Step 5, VTOL fixed wing airplane control servomechanism by airborne computer, manipulate respectively in safe altitude
The pitch of the complete dynamic aileron in left and right, and the deflection angle of complete dynamic vertical tail is manipulated, continued with the motion flight of tapered auger line
Climb, and the radius of tapered auger line motion flight increasing finally breaks away from tapered auger line with rectilinear flight campaign
Motion flight, finally realizes the motion of rectilinear flight mode, in the process real time management or so engine power and thrust side
To.
It is the reverse movement of step 4, step 5 in VTOL fixed wing airplane descent.
The invention has the beneficial effects as follows, the present invention provides patent 2015203521439, and VTOL fixed wing airplane is in warship
The technical scheme taken off on ship, takes off relative to the helicopter of traditional autonomous dynamic, and AV8B's takes off vertically with significantly excellent
More property, for fleet air defense, ocean escort, aircraft carrier miniaturization is respectively provided with important meaning and far-reaching influence.
