Some schemes, generations of canard wing is arrow form, but from the front pictures show canard wing is trapezoid. According to minimize edge Angle of edge alighnment principle, the airfoil shape should and canard wing, consistent, before and after canard flanges alignment. If the last proof canard wing not trapezoid but arrow form, it also just as well, canard wing and before margin does not necessarily need left facing left, left face right can too. Wing applying M shape or W shaped although also accord with the edge alighnment principle, but increased inside and convex Angle,[link widoczny dla zalogowanych], increase to radar reflective characteristic, can avoid the best to avoid predators, only in the former edge cause wing root length than the body when it necessity. Double hang tail shapes and estimate the canard consistent, be helpful for edge alignment. Hang tail pointed crosswise a sword, estimate, canard wing also have same Angle of inclined cut one knife. Mig vertical tail often have such a sword, F - 15 wing tips is like this, it is in order to dodge the wingtip eddy current caused by the extra resistance.
Generations of canard wing is full motion, generations of double hang tail is full motion. Known fighter, only T - 50 is full motion hang tail, F - 22-35 and F is regular fixed hang tail plus moving actuator. Full motion hang tail and full motion flat tail, as the flight control requirements and increase the level of results. Traditional transverse stability of the plane design, the aft fuselage horizontal direction is umbriferous area should be greater than before, such aircraft fuselage like vane,[link widoczny dla zalogowanych], as in horizontal is natural and stable. Aft fuselage refers to the machine centre of gravity after part. Modern fighter aircraft engine account for part of the small weight, the plane focus more on the wing, so also after depend, causing F - 18 such as long as crane nose out in front of appearance. But such, after the fuselage umbriferous area will rely more and more hang tail, a hang tail is insufficient,[link widoczny dla zalogowanych], sometimes still need two hang tail. Double hang tail and additional benefits, can while heading for the reef surface differential action (namely simultaneously to the outside,[link widoczny dla zalogowanych], or simultaneously to), act as braking are used. Like F - 18 that WaiQing double hang tail actuator differential moves, still can generate additional pressure tail torque, help aircraft early payable, shorten take-off distance. WaiQing double hang tail and lower side of the benefits of radar reflection area. For distant illuminate over radar,[link widoczny dla zalogowanych], Angle basically can be equated to incident, erect the vertical level tail like a mirror reflection, WaiQing vertical tail is significantly reduced radar reflective characteristic. But WaiQing double hang tail in flight control on comparison at odds, not only produce yaw torque, also produce roll moments, and to achieve the pilot's no worries operation, require a higher flight control level. Generations than this also took one step, using a full motion hang tail. Full motion hang tail passively natural stability for use active control attained direction stability, benefit is can use smaller hang tail, weight and resistance are minor, radar reflection area is small,[link widoczny dla zalogowanych], the disadvantages of flight control requirement is further improved. Generations using this extreme technology, explains the flight control of advanced been confidence.
But generations of flight control of abnormal lies not in this, but in the moving of edge. In numerous strakes, little human attention is canard wing and between the edge of, there is a clear suture, this can only be moving of edge. Generations of distance coupling canard notice, conduce to the agility of balancing role helicopter pointing to, but for stable hovering needed vortex lift doesn't help. European "typhoon" in canard wing added pair and between little turbulence piece, used to produce vortex lift. Generations greatly took one step, canard wing and between the edge of is moving. Because and wings in the same horizontal plane's sake, generations of canard wing slightly on the reverse. Say commonly against wing enhance the stability of roll, used in natural stability shortage of placing wing. Generations canard equivalent single wing, on the single wing for use against is very rare and agility is negative effects, but canard area is too small, this effect can be neglected. But canard wing slightly, and to reduce the edge of keep out, can strengthen the role of edge. Generations of edge of a small, narrow, after all,[link widoczny dla zalogowanych], too lenient canard wing behind the useless. But that does not mean of edge is inaction, especially of edge can be controlled prolapse. The moving of edge can reinforce vortex lift, and can control the eddy current trends. Mege - 29K also used a similar technique, not just the same, but some like-minded. Mege - 29K big of edge under a pair of off and landing is down in the turbulence piece, this pair of turbulence piece greatly enhances the vortex lift, so don't need Sue - 33 such canard can be achieved the carrier's sliding jump take-off. The difference is that the turbulence 29K mege - piece only in takeoff and landing on flight dynamic used when no help, generations of moving edge of all the time can also play a role, this is a new design and improving the design of flight control difference,[link widoczny dla zalogowanych], also is the difference.
